DESCRIPTION:This session looks at where open hardware is heading\, starting
  from recent ground up developments at FOSSASIA and extending to global tr
 ends across the open hardware community. With perspectives from FOSSASIA d
 evelopers and open hardware experts\, it explores decentralised collaborat
 ion\, open silicon and firmware stacks\, manufacturing realities\, and how
  openness can be sustained at scale.\nIn 2025\, teams at FOSSASIA initiate
 d several open hardware projects developed entirely from the ground up\, i
 ncluding a new ARM based Pocket Science Lab\, an updated LED Badge platfor
 m\, and an NFC powered ePaper badge enabling energy independent content tr
 ansfer. However\, this session goes beyond a project update. It situates t
 hese developments within a wider global movement of open hardware initiati
 ves across Asia\, Europe\, and other regions. Drawing on experiences from 
 FOSSASIA as well as broader perspectives from the international open hardw
 are community\, the talk examines where open hardware is heading as a dece
 ntralised\, collaborative practice. With input from international experts 
 and community contributors\, the session will explore trends emerging\, in
 cluding evolving manufacturing models\, open silicon and firmware stacks\,
  supply chain resilience\, and the realities of sustaining openness at sca
 le.\n

DESCRIPTION:Build your own open-source Bitcoin signing device with a Raspbe
 rry Pi Zero\, camera and display! We have kits for 45€\nSeedsigners are op
 en-source DIY signing devices which can be built using "normal" hardware l
 ike a Raspberry Pi and act as kind of hardware wallets to sign Bitcoin tra
 nsactions. Since the hardware is missing a secure element chip\, the keys 
 are saved externally\, usually via self-drawn QR-codes which are read agai
 n for every use via the build-in camera.\n\nWe brought a few kits with us 
 which we sell for 45€ and build together. We will solder the 40pin GPIO he
 ader to the Raspberry Pi Zero\, flashing the firmware on the MicroSD card 
 and then build everything together in the 3d-printed enclosure.\n\nThe kit
  includes:\nRaspberry Pi Zero 1.3 (without Wifi or Bluetooth chip)\, GPIO-
 header to solder\nDisplay-Hat with joystick and buttons\nCamera\n64GB Micr
 oSD card\nMicroUSB to USB-C cable\n3D printed enclosure\n6 printed templat

DESCRIPTION:Free/libre software promotes users' rights\, safeguards privacy
 \, individual control over technology and fosters autonomy and decentralis
 ation within our communities. In contrast\, proprietary software limits us
 er freedoms leading to centralised monopolies that often misuse their powe
 r to oppress and exploit. This imbalance can result in malware\, degradati
 on of privacy and service enshitification. Unfortunately\, many remain una
 ware of the unjustices created by proprietary software\, but increased awa
 reness and shift towards free software can fuel resistance.\n\nReplacing o
 f proprietary software is a crucial first step to liberate users\, yet man
 y need support to make this transition successfully. Workshops for system 
 installation\, repair centres and tech-savvy friends can offer essential a
 ssistance. However\, what is the most effective way to offer this support?
  Which software should be recommended and how to engage the novice users w
 hile minimising the challenges associated with the transition?\n\nIn this 
 workshop we aim to discuss possible strategies of providing information on
  the path to software freedom. We will examine the installation process an
 d ongoing use of free software within our circles. Key topics will include
  sparking interest in free distributions\, selecting ideal software config
 uration\, and exploring various forms of assistance during installation. A
 dditionally\, we'll address onboarding into the new system and troubleshoo
 ting potential issues. Finally\, we hope to gather and share ideas on stre
 amlining the process for everyone involved.\n

DESCRIPTION:The right to respect for digital integrity is an emerging right
  to protect people's digital lives. \n\nThis talk will introduce this new 
 legal concept\, its possible implications for data protection and how this
  concept is being introduced in the current legal framework. The talk will
  also be an update of the implementation work with the adoption of the rig
 ht in the Constitution of Geneva voted with 94% approval rate on the 18th 
 of June 2023 and with 91% in Neuchâtel in November 2024. Zurich will be vo
 ting in November 2025.\nEvery human evolves today in multi-dimensional phy
 sical and digital environment. If each individual is to keep its individua
 lity and autonomy in its choices\, it must be protected and given effectiv
 e tools to defend its own autonomy.\n\nRecognizing that human life has bee
 n digitally extended must question ourselves on what makes us human today.
  Should personal data be considered as component of the person\, rather th
 an objects that can be owned by whoever collects that data? Should our dig
 ital integrity be protected?\n\nIf each human person already has a right t
 o physical and mental integrity (Swiss Constitution article 10 al.2)\, sho
 uldn’t it have a right to digital integrity?\n\nAlexis Roussel has been co
 -authoring a book on the right to Digital Integrity. He is an advocate in 
 digital public policies in Switzerland.\n

DESCRIPTION:Digital identity is sold as a path to trust\, inclusion\, and "
 digital empowerment." In practice\, it is a brittle control surface: a set
  of design choices that decide who is seen\, who is excluded\, and who can
  be targeted at scale.\n\nBorn from a landmark research project\, _The Dig
 ital Identity Event Horizon_\, this talk describes the 2025 "mask-off mome
 nt" for digital identity: the point where multiple comforting narratives c
 ollapse and the core use of identity systems as population-management infr
 astructure becomes hard to deny. Using short vignettes from New Design Con
 gress case-study work (Estonia\, the US\, Australia\, Gaza\, and others)\,
  it shows how ambiguity\, vendor incentives\, and governance theatre turn 
 identity into fraud-permissive\, coercion-ready infrastructure\n\nIn respo
 nse to this decline\, this talk concludes proposes a working model of the 
 digital self as a socio-technical system with six properties: serialisatio
 n\, custodianship\, presentation\, authentication\, authorisation\, and as
 setisation\, and offers new framing and threat models to help understand h
 ow digital identity creates brittle societies.\nDespite decades of cryptog
 raphy\, security practice\, and best practice deployment\, digital identit
 y remains the weakest link in systems design because its core terms stay v
 ague while its consequences are concrete. What does it actually take to as
 semble a digital identity? What do different implementations share\, even 
 when they claim to be radically different? And what happens when those def
 initions are left elastic enough to serve whoever holds power?\n\n"The mas
 k-off moment" tracks the convergence of capability (biometrics\, sensors\,
  AI triage\, mass digitisation)\, institutional incentives (risk scoring\,
  eligibility gates\, compliance automation)\, and political will. The resu
 lt is an emerging form of bureaucratic violence we are not prepared to nam
 e\, much less govern.\n\nThis talk traces how digital identity became weap
 on-ready through optimistic framing and opportunistic ambiguity\, then off
 ers a concrete frame to interrogate any proposal: what it will do on its b
 est day\, what it will do on its worst day\, and which parts of the system
  will be impossible to “add accountability to later.” The intended audienc
 e is policymakers\, technologists\, designers\, and civil-society people w
 ho are tired of vague promises and want a usable model that survives conta
 ct with reality.\n

 deployment as well. But what kinds of other PKI wizardry can we do with Na
 mecoin and Tor?\nTopics to be covered include:\n\n* How we can use Namecoi
 n as a PKI with ~0 bytes of blockchain overhead.\n* How Namecoin's smart c
 ontract functionality (allowing multisig and timelocks to control updating
  a name) interacts with PKI use cases.\n* How we generalized Namecoin and 
 Tor PKI to work with non-TLS protocols.\n* How revocations can be handled 
 securely.\n* How we ensured anonymity (including Tor stream isolation) des
 pite TLS implementations not providing API's for this.\n* How the anonymit
 y protections actually *improved* performance.\n* How all of the above int
 eroperates with existing software.\n

DESCRIPTION:The Great Firewall of China (GFW) is one of\, if not arguably t
 he most advanced Internet censorship systems in the world. Because repress
 ive governments generally do not simply publish their censorship rules\, t
 he task of determining exactly what is and isn’t allowed falls upon the ce
 nsorship measurement community\, who run experiments over censored network
 s. In this talk\, we’ll discuss two ways censorship measurement has evolve
 d from passive experimentation to active attacks against the Great Firewal
 l.\nWhile probing the Great Firewall’s DNS injection system in 2021\, we n
 oticed something strange: Sometimes the injected responses contained weird
  garbage. After some investigation\, we realized we’d stumbled onto a memo
 ry disclosure vulnerability that would give us an unprecedented window int
 o the Great Firewall’s internals: Wallbleed.\n\nSo we crafted probes that 
 could leak up to 125 bytes per response and repeatedly sent them for two y
 ears. Five billion responses later\, the picture that emerged was... conce
 rning. Over 2 million HTTP cookies leaked. Nearly 27\,000 URL parameters w
 ith passwords. SMTP commands exposing email addresses. We found traffic fr
 om RFC 1918 private addresses - suggesting we were seeing the Great Firewa
 ll’s own internal network. We saw x86_64 stack frames with ASLR-enabled po
 inters. We even sent our own tagged traffic into China and later recovered
  those exact bytes in Wallbleed responses\, proving definitively that real
  user traffic was being exposed.\n\nIn September 2023\, the patching began
 . We watched in real-time as blocks of IP addresses stopped responding to 
 our probes. But naturally the same developers that made this error in the 
 first place made further mistakes. Within hours\, we developed “Wallbleed 
 v2” queries that still triggered the leak. The vulnerability persisted for
  another six months until March 2024.\n\nGFW measurement research went bac
 k to business as usual until September of this year when an anonymous sour
 ce released 600GB of leaked source code\, packages\, and documentation via
  Enlace Hacktivista. This data came from Geedge Networks - a company close
 ly connected to the GFW and the related MESA lab. Geedge Networks develops
  censorship software not only for the GFW but also for other repressive co
 untries such as Pakistan\, Myanmar\, Kazakhstan\, and Ethiopia.\n\nWe will
  discuss some of our novel findings from the Geedge Networks leak\, includ
 ing new insights about how the leak relates to Wallbleed.\n\nWallbleed and
  the Geedge Networks leak show that censorship measurement research can be
  about more than just actively probing censored networks. We hope this tal
 k will be a call to arms for hackers against Internet censorship.\n\n\nMor
 e information about Wallbleed can be found at the GFW Report:\nhttps://gfw

DESCRIPTION:Like 39C3\, the last CCC camp (2023) and congress (38C3) have s
 een volunteer-driven deployments of legacy ISDN and POTS networks using a 
 mixture of actual legacy telephon tech and custom open source software. Th
 is talk explains how this is achieved\, and why this work plays an importa
 nt role in preserving parts of our digital communications heritage.\nJust 
 like at this very event (39C3)\, the last few years a small group of volun
 teers has delpoyed and operated legacy telephony networks for ISDN (digita
 l) and POTS (analog) services at CCC-camp2023 and 38C3. Anyone on-site can
  obtain subscriber lines (POTS\, ISDN BRI or PRI service) and use them for
  a variety of services\, including telephony\, fax machines\, modem dial-u
 p into BBSs as well as dial-up internet access and video telephony.\n\nThe
 se temporary event networks are not using soft-PBX or VoIP\, but are built
  using actual de-commissioned hardware from telecom operators\, including 
 a Siemens EWSD digital telephone exchange\, Nokia EKSOS V5 access multiple
 xers\, a SDH ring for transporting E1 carriers and much more.\n\nWhile som
 e may enjoy this for the mere hack value\, others enjoy it to re-live the 
 digital communication sear of their childhood or youth.  Howevre\, there i
 s a more serious aspect to this: The preservation and restoration of early
  digital communications infrastructure from the 1970s to 1990s\, as well a
 s how to operate such equipment.  As part of this effort\, we have already
  been able to help communications museums to fill gaps in their collection
 s.\n\nThe talk will cover\n* the equipment used\,\n* the network hierarchy
  we build\,\n* the services operated\n* the lessons learnt\n* newly-writte
 n open source software for interfacing retro telcommunications gear\n

DESCRIPTION:This project transforms a classic rotary phone into a mobile de
 vice. Previous talks have analyzed various aspects of analogue phone techn
 ology\, such as rotary pulse detection or ringing voltage generation. Now 
 this project helps you get rid of the cable: it equips the classic German 
 FeTAp 611 with battery power and a flyback SMPS based ringing voltage gene
 rator - but still maintains the classical look and feel. The talk demonstr
 ates the journey of bridging analog and digital worlds\, explaining how ca
 reful design connects a vintage phone to today’s mobile environment - in a
  way that will make your grandparents happy.\nThere are people who throw a
 way old telephones - and then there are those who find them in the garbage
  and think\, „How can a microcontroller actually read the digits from a ro
 tary dial?“\nThis talk follows the journey of transforming a classic Germa
 n FeTAp 611 rotary phone into a mobile device while keeping its vintage ch
 arm. Building on earlier retrofits\, this project aims to combine the foll
 owing design goals into a mobile version of the Fernsprechtischapparat:\n\
 n- Grandparents-compatible – The phone shall be easy to use by non-technic
 al people\, showing the same look and feel as the original phones\, includ
 ing details such as a dial tone.\n- easy phone switching – Switching betwe
 en FeTAp and regular cellphone shall not require unscrewing the phone to s
 witch SIM cards.\n- standard components – PCB/PCBA suppliers shall be capa
 ble of manufacturing boards at a reasonable price.\n- device-agnostic circ
 uit design – Adapting to different phones (e.g. W48\, FeTAp 791\, FeTAp 61
 1) shall minimize the need for changes in the schematic. This includes a r
 inging voltage generator that shall be powerful enough to drive an old W48
  phone.\n\nThis talk will walk you through certain aspects of the German a
 nalog telephony standard 1TR110-1\, and the challenges faced when implemen
 ting those on a battery-powered device with little space. It explains\n- t
 he state machine implemented on an STM32 microcontroller\,\n- how to conne
 ct old carbon microphones to modern audio electronics\,\n- designing (and 
 avoiding mistakes in) a flyback based SMPS to generate 32V - 75V ringing v
 oltage\,\n- how to generate 25 Hz AC using an H-bridge\,\n- and how to lay
 out the PCB such that the ancient second handset connector can now be used
  for USB-C charging.\n\nIn the course of the development\, I discovered th
 at the project is not only a good way to get a glimpse into various aspect
 s of ancient and modern types of electronics - but also into people’s reac
 tions when such a phone suddenly starts ringing on a flea market… :-)\n

DESCRIPTION:Did you ever wonder where all the drugs\, which you can get at 
 a pharmacy\, come from? Who makes them\, and how? Well\, there is no easy 
 answer\, because the process of drug discovery and development is a very c
 omplex\, expensive\, and challenging journey\, riddled with many risks and
  failures. This holds true for all types of drugs\, from a simple pill to 
 an mRNA vaccine or a gene therapy. Today\, scientists support this process
  with a variety of AI applications\, cutting-edge technologies\, automatio
 n\, and a huge amount of data. But can the race for new medicines and cure
 s succeed only through more technology\, or do we need to rethink the enti
 re process? Let’s take a look at how the drug discovery and development pr
 ocess has worked so far\, and how this entire process is changing – for be
 tter or worse.\nAfter presenting a high-level overview of the path from an
  idea to the medicine that you can buy at a pharmacy\, this talk will pres
 ent and discuss the following aspects of the drug discovery and developmen
 t process:\n(1) The translation of an idea into a drug for a human patient
  faces many critical moments along the development process. This so-called
  “translational gap” is addressed through experiments in a test tube (or P
 etri dish)\, experimentation in lab animals\, and eventually testing in hu
 mans. However\, findings in a standard cell line or in a mouse do not nece
 ssarily reflect the complexity of biological processes in a human patient.
  Currently\, there are many technological advancements under way to improv
 e the current drug discovery and development process\, and possibly even r
 eplace animal studies in the future (e.g.\, organs-on-chip). Nevertheless\
 , the fundamental issues surrounding translational research remain\, such 
 as the lack of standardization\, the limitations of model systems\, and va
 rious underlying clinical biases.\n(2) Like in many industries today\, AI 
 applications are introduced at multiple levels and for various purposes wi
 thin the drug discovery and development continuum. Often\, a lot of hope i
 s placed in AI-based technologies to accelerate the R&D process\, increase
  efficiency and productivity\, and identify new therapeutic approaches. In
 deed\, there are many highly useful examples\, such as the automation of i
 mage analysis in research\, which replaces repetitive tasks and hence free
 s up a lot of time for researchers to do meaningful research. However\, th
 ere are also many applications that are likely misguided\, because they st
 ill face fundamental problems in evaluating scientific knowledge. For inst
 ance\, the use of LLMs to summarize huge amounts of very complex and heter
 ogeneous scientific data relies on the accuracy\, completeness\, and repro
 ducibility of the available scientific data\, which is often not the case.
  In addition\, AI is often employed in an IT environment with questionable
  data security and ownership practices\, such as the storage of sensitive 
 research data on third-party cloud platforms.\n(3) Until now\, the overwhe
 lming majority of drugs have been developed to treat large patient populat
 ions\, which represent a considerable market and ultimately ensure a retur
 n on investment. Today\, however\, most common and homogeneous diseases ca
 n already be managed\, often with several (generic) drugs. Slight improvem
 ents to current drugs do not justify a large profit margin anymore\, so th
 e focus of drug discovery and development is shifting toward more heteroge
 neous and rare diseases\, for which no or only poor treatments are availab
 le. Novel medicines in those disease areas hold the promise of substantial
  improvement for patients\; however\, these new patient (sub)populations\,
  and thus markets\, are much smaller\, leading to premium prices for indiv
 idualized therapies in order to ensure a return on investment. This paradi
 gm shift toward individualized therapy - referred to as precision and pers
 onalized medicine - is supported by the advent of novel technologies and t
 he accumulation of large bodies of data.\n(4) The rise of precision and pe
 rsonalized medicine is challenging the current business model of today’s p
 harmaceutical industry\, suggesting that the era of blockbuster drugs migh
 t be over. Moreover\, many intellectual property rights for blockbuster dr
 ugs are going to expire in the next few years\, ending the market dominanc
 e of a number of pharma companies and sending the current industry landsca
 pe into turmoil. These developments will likely alter the current modus op
 erandi of the entire biopharmaceutical development process\, and it is not
  clear how the next few years will look like.\n

DESCRIPTION:Großen Herausforderungen im Gesundheitswesen soll mittels Techn
 ik und Eigenverantwortung begegnet werden. Die Hoffnung: „KI“ und Digitali
 sierung machen das System effizienter\; Selbstoptimierung und mehr Eigenve
 rantwortung halten die Menschen länger gesund. Der Vortrag analysiert aktu
 elle Diskurse rund um Digitalisierung und Gesundheit\, und fragt kritisch\
 , wie diese Entwicklung ohnehin bestehende soziale Ungleichheiten verschär
 fen könnte. Am Ende bleibt die Frage: Wie könnten tragfähige Lösungen fürs
  Gesundheitssystem aussehen?\nIn der Analyse sind sich alle einig: Das Ges
 undheitssystem steht vor großen Herausforderungen\, die von explodierenden
  Kosten\, wachsenden Zugangsbarrieren bis hin zum anstehenden demographisc
 hen Wandel reichen: viele Menschen werden alt und kränker\, während gleich
 zeitig sehr viele Mitarbeiter:innen des Gesundheitswesens in Rente gehen. 
 Wir brauchen also Lösungen fürs Gesundheitssystem\, die nachhaltig tragen 
 und Menschenwürde ermöglichen.\n\nWährend ganz unterschiedliche Lösungsans
 ätze diskutiert werden\, taucht ein Narrativ immer wieder auf: Dass Digita
 lisierung durch massive Effizienzgewinne die bestehenden Probleme im Gesun
 dheitswesen fixen werden: Dank „KI“ sollen Menschen weniger häufig Ärzt:in
 nen brauchen\, zum Beispiel\, indem durch Symptomchecker und Co vorgefilte
 rt wird\, wer wirklich behandelt werden muss\, und wer nicht. Manche behau
 pten\, dass Hausärzt:innen künftig ein vielfaches an Patient:innen behande
 ln könnten\, wenn nur die richtigen technischen Hilfsmittel gefunden wurde
 n. Und längst befinden wir uns tatsächlich in einer Realität\, in der Chat
 s mit LLMs an vielen Stellen zumindest Dr. Google ersetzt haben.\n\nWeiter
 e Lösungsansätze zielen auf mehr Eigenverantwortung ab: "Longevity" ist da
 s Trendwort in aller Munde. Ein Ansatz der „Langlebigkeit“\, der maßgeblic
 h durch technische \nMaßnahmen gestützt sein soll: Selbstoptimierung per A
 pp\, „KI“ als individueller Gesundheitsassistent und allerlei experimentel
 le Untersuchungen. Die Grundidee: Wenn Menschen länger gesund bleiben und 
 leben\, wird das Gesundheitssystem weniger belastet\, während Menschen län
 ger zu Gesellschaft und Wirtschaft beitragen können. Die ideologischen Gru
 ndzüge und Geschäftsmodelle der „Longevity“ kommen aus den USA\, von Tech-
 Milliardären und ihren Unsterblichkeitsfantasien bis hin zu wenig seriösen
  Gesundheitsinfluencer:innen\, die am Ende oft mehr schaden als dass sie z
 u einem größeren Wohlbefinden ihrer Kund:innen beitragen würden - und trot
 zdem hunderttausende auf Social Media in ihren Bann ziehen.\n\nDer Vortrag
  zieht Verbindungslinien zwischen naiver Technikgläubigkeit\, aktuellen Di
 skursen im Gesundheitswesen\, ihren fragwürdigen ideologischen Wurzeln und
  der Frage\, wie wir Herausforderungen und insbesondere sozialen Ungleichh
 eiten im Feld der Gesundheit wirklich effektiv begegnen.\n

DESCRIPTION:A 595€ wheelchair remote that sends a handful of Bluetooth comm

 A speed upgrade from 6 to 8.5 km/h locked behind a 99.99€ paywall - becaus
 e apparently catching the bus is a premium feature.\n\nWelcome to the wond
 erful world of DRM in assistive devices\, where already expensive basic mo
 bility costs extra and comes with in-app purchases! And because hackers go
 nna hack\, this just could not be left alone.\nThis talk depicts the rever
 se engineering of a popular electric wheelchair drive system - the Alber e
 -motion M25: a several thousand euro assistive device that treats mobility
  like a SaaS subscription. Through Android app reverse engineering\, propr
 ietary Bluetooth protocol analysis\, hours of staring at hex dumps (instea
 d of the void)\, and good old-fashioned packet sniffing\, we'll expose how
  manufacturers artificially limit essential features and monetize basic hu
 man mobility.\n\nWhat you'll learn:\n\n- how a 22-character QR code sticke
 r\, labeled as "Cyber Security Key"\, becomes AES encryption\n- why your 6
 000€ wheelchair drive includes an app with Google Play Billing integration
  for features the hardware already supports\n- the internals\, possibiliti
 es and features of electronics worth 30€ cosplaying as a 595€ medical devi
 ce\n- the technical implementation of the "pay 99.99€ or stay slow" speed 
 limiter (6 km/h vs 8.5 km/h)\n- how nearly 2000€ in hardware and app featu
 res can be replaced by a few hundred lines of Python\n- why the 8000€ even
  more premium (self-driving) variant is literally identical hardware with 
 a different Boolean flag and firmware plus another (pricier) remote\n\nWe'
 ll cover the complete methodology: from initial reconnaissance\, sniffing 
 and decrypting packets to reverse-engineer the proprietary communication p
 rotocol\, to PoCs of Python replacements\, tools\, techniques\, and ethica
 l considerations of reverse engineering medical devices.\n\nThis is a stor
 y about artificial scarcity\, exploitative DRM\, ethics and industry power
 \, and how hacker-minded creatures should react and act to this.\n\nThis t
 alk will be simultaneously interpretated into German sign language (Deutsc
 he Gebärdensprache aka. DGS).\n

DESCRIPTION:What power structures are inherent to the field of computer-gen
 erated art? In the year 1965\, so 60 years ago\, the first three exhibitio
 ns of art created with the help of computers took place - in part independ
 ently of each other. We want to present the interesting aspects of develop
 ments since then and discuss them with Frieder Nake\, one of the people wh
 o exhibited in those very beginnings and followed those developments with 
 a critical attitude.\nWe want to look at the complex topic of art created 
 with computers\, beginning with some careful and barely noticed first expe
 riments and emerging into an ever more diverse and creative field\, from d
 ifferent angles. In particular\, we want to focus on the dynamics of power
  and how these developments were influenced by their context - from social
  movements to political pressure.\n\nWe want to start with explaining how 
 the initial developments\, both from an artistic - concrete art - and tech
 nological - the evolution of computers and the creation of the drawing mac
 hine Zuse Z64 in Germany and film techniques in the US\, respectively - to
 ok place. We will do so in the context of the first three exhibitions that
  all took place in the year 1965. Their artworks were created by Georg Nee
 s in Stuttgart\, A. Michael Noll with Béla Julesz in New York and Frieder 
 Nake with Georg Nees\, again in Stuttgart.\n\nIn the following\, we will t
 ry to give an outline of further developments. We provide examples how hie
 rachies in art and science have developed and played a role in different e
 vents. In the domain of computer-generated art\, similar to other art\, th
 ere are two large influences hidden for the typical recipent of this art -
  galleries and critics. We will discuss this exemplary with early exhibiti
 ons of Frieder Nake being described by the FAZ and later on\, how the east
 -west conflict has influenced the art and its exhibitions. Among other iss
 ues\, we discuss patriarchal structures\, the commercial side of art\, how
  old tech is sold as revolutionary and how progress is still as connected 
 with threatening feelings as in the early years.\n\nLooking back at the be
 ginnings\, it is interesting to observe how artists - also with an artisti
 c\, rather than technical background - worked with the limitations and ove
 rcame them. Fortunately\, the technological entry barrier to create algori
 thmic art yourself has drastically decreased over time and we want to enco
 urage you to experiment yourself!\n\nFrieder Nake is creating algorithmic 
 drawings and doing visual research since 1964. In 1971\, he published the 
 influential essay "there should be no computer art" and he has been teachi
 ng computer graphics at the University of Bremen for decades. Enna Gerhard
  is pursuing a PhD in theory of computer science and creates algorithmic d
 rawings in the meantime.\n

DESCRIPTION:This talk reveals our in-depth vulnerability research on the Wi
 ndows Recovery Environment (WinRE) and its implications for BitLocker\, Wi
 ndows’ cornerstone for data protection. We will walk through the research 
 methodology\, uncover new 0-day vulnerabilities\, and showcase full-chain 
 exploitations that enabled us to bypass BitLocker and extract all the prot
 ected data in several different ways. This talk goes beyond theory - as ea
 ch vulnerability will be accompanied by a demo video showcasing the comple
 te exploitation chain. To conclude the talk\, we will share Microsoft’s ke
 y takeaways from this research and outline our approach to hardening WinRE
  and BitLocker.\nIn Windows\, the cornerstone of data protection is BitLoc
 ker\, a Full Volume Encryption technology designed to secure sensitive dat
 a on disk. This ensures that even if an adversary gains physical access to
  the device\, the data remains secure and inaccessible.\n\nOne of the most
  critical aspects of any data protection feature is its ability to support
  recovery operations in case of failure. To enable BitLocker recovery\, si
 gnificant design changes were implemented in the Windows Recovery Environm
 ent (WinRE). This led us to a pivotal question: did these changes introduc
 e any new attack surfaces impacting BitLocker?\n\nIn this talk\, we will s
 hare our journey of researching a fascinating and mysterious component: Wi
 nRE. Our exploration begins with an overview of the WinRE architecture\, f
 ollowed by a retrospective analysis of the attack surfaces exposed with th
 e introduction of BitLocker. We will then discuss our methodology for effe
 ctively researching and exploiting these exposed attack surfaces. Our pres
 entation will reveal how we identified multiple 0-day vulnerabilities and 
 developed fully functional exploits\, enabling us to bypass BitLocker and 
 extract all protected data in several different ways.\n\nNotably\, the fin
 dings described reside entirely in the software stack\, not requiring intr
 usive hardware attacks to be exploited.\n\nFinally\, we will share the ins
 ights Microsoft gained from this research and explain our approach to hard
 ening and further securing WinRE\, which in turn strengthens BitLocker.\n

DESCRIPTION:A spectre is haunting Europe—the spectre of bureaucracy. All th
 e Powers of old Europe have entered into an unholy alliance to exorcise th
 is spectre: The EU Commission\, Member States\, industry\, even J.D. Vance
 . This threatens the digital rights and rules built up in the last decade.
 \nThe new EU Commission has an agenda. What started with the report of for
 mer European Central Bank chief Mario Draghi on Europe's "competitiveness"
  has quickly turned into "getting rid of bureaucracy"\, then into "simplif
 ication"\, and finally open "deregulation". What this means is that a larg
 e number of European laws that were adopted in the last decade to ensure s
 ustanabiliy\, protect human rights along the whole supply chain\, or to en
 sure our digital rights\, are watered down\, and core elements are scrappe
 d.\n\nIn terms of the EU's digital rulebook\, it has already started in Ma
 y with the deletion of a core compliance element in the General Data Prote
 ction Regulation (GDPR) - the obligation to keep records of your processin
 g activities. While it sounds harmless - all the other rights and obligati
 ons still appy - it means that companies have no clue anymore what persona
 l data they process\, for which purposes\, and how.\n\nA much larger revis
 ion has been proposed on 19th November 2025\, with the "omnibus" legislati

DESCRIPTION:Science advances by extending our senses beyond the limits of h
 uman perception\, pushing the boundaries of what we can observe. In photon
  science\, imaging detectors serve as the eyes of science\, translating in
 visible processes into measurable and analysable data. Behind every image 
 lies a deep understanding of how detectors see\, respond and perform.\n\nA
 t facilities like the European XFEL\, the world's most powerful X-ray free
 -electron laser located in the Hamburg metropolitan area\, imaging detecto
 rs capture ultrashort X-ray flashes at MHz frame rates and with high dynam
 ic range.  Without these advanced detectors\, even the brightest X-ray las
 er beam would remain invisible. They help to reveal what would otherwise s
 tay hidden\, such as the structure of biomolecules\, the behaviour of nove
 l materials\, and matter under extreme conditions. But how do we know they
  will perform as expected? And how do we design systems capable of “seeing
 ” the invisible?\n\nI will take a closer look how imaging technology in la
 rge-scale facilities is simulated and designed to make the invisible visib
 le. From predicting detector performance to evaluating image quality\, we 
 look at how performance simulation helps scientists and engineers understa
 nd the “eyes” of modern science.\nX-ray imaging detectors have come a long
  way in the last 15 years\, turning ideas that once seemed impossible into
  realities. Imaging detectors in photon science are more than just high-sp
 eed cameras. They are complex systems operating at the limits of what’s ph
 ysically measurable. Understanding how they behave before\, during\, and a
 fter experiments is essential to advancing both the technology and the sci
 ence it enables.\n\nIn this talk\, I’ll take you inside the world of detec
 tor simulation and performance modelling. I’ll explore how tools like Mont
 e Carlo simulations\, sensor response models\, and system-level performanc
 e evaluations are used to:\n\n- Predict detector behaviour in extreme cond
 itions (such as MHz X-ray bursts)\, and\n- identify critical performance b
 ottlenecks before production.\n\nBy linking imaging technology with simula
 tion and modelling\, we can better interpret experimental data and design 
 the next generation of scientific cameras. Beyond the technical aspects\, 
 this talk reflects on the broader theme of how we “see” though technology\
 , what it means to make the invisible visible\, and how simulation changes
  not only how we build instruments\, but also how we understand them.\n

DESCRIPTION:Learn from our mistakes during the first iteration of Network O
 perations for Europe's largest furry convention\, Eurofurence.\nDieses Jah
 r hat ein kleines Team aus dem Chaos\, Furries und Chaos-Furries ein neues
  Netzwerk-OC gegründet\, um die Eurofurence mit gutem premium 👌 Internetz 
 auszustatten. Wir erzählen von unseren Erfahrungen und den sozialen sowie 
 technischen Herausforderungen.\nZum Zeitpunkt der 29. Eurofurence (also di
 eses Jahr) hatte das Event eine Größe erreicht\, bei der typische Event-Lo
 cations unsere speziellen Anforderungen nicht mal eben so erfüllen konnten
 . Beispielsweise ist eine aufwändige Audio/Video-Produktion Teil der Eurof
 urence\, welche ein IP-Netz mit hoher Bandbreite\, niederiger Latenz\, nie
 drigem Jitter\, Multicast-Transport und präzise Zeitsynchronisierung benöt
 igt. Deshalb wurde dieses Jahr das _Onsite Eurofurence Network Operation C
 enter_ _(EFNOC)_ gegründet. Unsere Aufgabe sollte es sein\, alle Anforderu
 ngen der anderen Teams kompetent zu erfüllen wovon wir euch in diesem Vort
 rag etwas aus dem Nähkästchen erzählen wollen.\n\nGrob haben wir wärend de
 r EF29 das Team etabliert und ein Netzwerk gebaut\, welches für A/V-Produk
 tion\, Event-Koordination und Event-Management (z.B. Security\, Ticketing)
  benutzt wurde. Unser persönliches Ziel war es außerdem\, ein benutzbares 
 WLAN-Netzwerk für alle Besuchenden über dies gesamte Event-Venue hinweg zu
  schaffen – also von Halle H bis zum Vorplatz.\nUnsere Architektur bestand
  dafür aus einem simplen Layer2-Netzwerk mit VLAN-Unterteilung\, welches v
 on _Arista DCS-7050TX-72Q_ mit 40Gbit/s Optiken bereitgestellt wurde. Die 
 Aristas haben außerdem ein PTP-Signal propagiert\, welches von einer Meinb
 erg Master-Clock gesteuert wurde. Zusätzlich war ein Linux-Server als Hype
 rvisor für diverse Netzwerk-Services wie DNS\, DHCP\, Monitoring und Routi
 ng im Einsatz.\nSo zumindest der Plan\, denn während des Events wurden wir
  mit der Realität und vielen „spaßigen“ Problemen konfrontiert.\n\nUnser T
 alk wird sich unter anderem mit diesen technischen Problemen beschäftigen\
 , allerdings den Fokus nicht nur auf die technische Darstellung legen. Sta
 ttdessen werden wir auch beleuchten\, wie wir als Team menschlich unterein
 ander und in der Kommunikation mit anderen Teams damit umgegangen sind.\n

DESCRIPTION:**39C3 LED badge -- SMD for Beginners**  \n\nThe 39C3 LED badge
  contains 42 LEDs that blink under control of of a pre-programmed 4 cent m
 icrocontroller. When the badge is alone\, the LEDs will blink randomly. Wh
 en it is among friends (when there are other badges nearby)\, it will disp
 lay a chaser pattern. \n\nIn this workshop you will learn how to solder Su
 rface Mounted Devices using a normal soldering iron.\n\nSuitable for begin
 ners. Under 16s only with responsible adult supervision.\n### 39C3 LED bad
 ge -- SMD for Beginners\n\n![39C3 LED badge](https://usercontent.events.cc
 c.de/congress/2025/hub/usercontent/b/7dccaedbb7ec/39C3badge.png)\n\nSurfac
 e Mounted Devices (SMDs) are small compared to Through Hole (TH) electroni
 c components\, and have the reputation of being difficult to work with as 
 a hobyist: Difficult to see and handle\, when you sneeze\, you loose them 
 and you can not easily use them on 2.54mm raster prototyping boards.\n\nSM
 D components are designed to be used in a reflow soldering process where t
 iny dots of solder paste are applied to a Printed Circuit Board (PCB)\, af
 ter which the SMD components are "Picked and Placed" on the PCB\, after wh
 ich the whole PCB is heated to the melting point of the solder ("reflowing
 ")\, actually completing the  electrical connections.\n\nThis workshop is 
 aimed at showing you that the reputation of being difficult to work with i
 s a bit undeserved\, and that you can also work with SMDs using just a  re
 gular soldering iron: With some simple tricks and a suitable selection of 
 components (not the smallest possible)\, the vast majority of people can s
 uccessfully complete this project.\n\nBeing able to solder SMD projects us
 ing just a simple soldering iron will also help you develop some skills th
 at are useful if you  need to do "rework" on reflow soldering projects. Re
 flow soldering is also not difficult to do as a hobbyist\, but requires a 
 few more tools like a stencil to apply solder paste and either an oven or 
 a hot plate to do the reflowing. It is\, however\, much quicker than solde
 ring the parts one by one\, and can yield more professional looking\, clea
 ner\, solder joints.\n\nThe project is an electronic name-badge - You shou
 ld write your name (or nick) on it and wear it. It contains 42 LEDs\, a mi
 crocontroller\, some support components and an InfraRed transmitter and re
 ceiver that allow it to communicate with other badges. When the badge dete
 cts the presence of other badges ("friends") nearby\, it will change its b
 ehaviour. It will not only interact with other 39C3 LED badges\, but also 
 with TBD badges - come visit the TBD assembly at komona or https://tbd.cam
 p\n\n![TBD badge](https://usercontent.events.ccc.de/congress/2025/hub/user
 content/e/d619de5f1be1/tbdbadge.png)\n\n### Costs\nThis workshop is donati
 on based. Materials costs are 2 euro per badge. Donations will go towards 
 1) covering costs of the badges\, 2) covering costs of running the hardwar
 e hacking area in general\, 3) covering costs of organizing TBD (see the T
 BD assembly at komona or https://tbd.camp)\n\n### Registration\nThe number
  of participants per session is limited. First come\, first served. Either
  get a participation voucher beforehand or show up early (there may be pla
 ces left).\nThere will be *numbered* paper vouchers available for each ses
 sion some time in advance of each session. If you get a voucher and do not
  show up *before* the designated starting time\, someone else may take you
 r spot. Please don't take multiple vouchers and don't take  vouchers if yo
 u don't actually plan to participate.\n\n### Getting a kit\nKits are part 
 of the workshop and not for sale separately. You can\, however easily sour
 ce your own PCBs and parts and make kits yourself because the design is  M
 IT licensed open source.\n\n### Links\nUnder construction: https://hackwin

DESCRIPTION:While the extreme right is on the rise in many countries and cl
 imate change is unrolling\, a promising future seems to be written: Accord
 ing to Elon Musk\, Sam Altman\, and some other “tech bros” it is to leave 
 the dying planet to go to space. With the help of something called “A(G)I”
 .\nBut what kind of future is the one that is promised? And what is the co
 nnection between power cycles of tech company owners and people who's beli
 eves can be called fascist? As we moved power through data in the hands of
  very view\, it is important to examine what ideas these view have in thei
 r heads.\nThis talk will explore the roots of today's tech fascism and its
  love for tech. From the early thoughts and movements in the US and Europe
  to Futurism and the Holocaust\, organised with Hollerith punching cards. 
 It will dive into the its blooming relationship with cybernetics\, and tak
 e a look in the future the “tech bros” want to lure us in.\nThis talk will
  address the often overlooked topic of how and when people get comfy with 
 diving into movements of hate and how to stop a white supremacy future whe
 re we will be sorted by machines.\nAnd\, in taking a look on past movement
 s opposing authoritarianism and will examine mindsets and possibilities of
  resistance as well as the possibility of restarting everything. Because w
 e have a planet and loved ones to lose.\nWear your safety cat-ears\, buckl
 e up\, it will be a wild\, but entertaining ride.\nThe idea of the Super-H
 uman is not a new one\, neither is the idea of charismatic „good“ leader n
 or to sort humans into classes\, races\, abilities. The idea of a view con
 trolling many by force and ideas that justify their rulership and crueltie
 s is an old one\, as is the opposing idea of a free society and humans as 
 equals.\nA central aspect is how people involved see the human nature and 
 according to that what society they want to build. And what role is intend
 ed for technology.\nIn the 19th century the beliefs of both the opposing s
 ides dripped into science\, as well as individual’s heads\, and social mov
 ements around the world. While some wanted to form a wold society of equal
 s others wanted to breed a master race that to control everything.\n\nThe 
 love of industrial leaders for authoritarianism has played an important ro
 le since the beginning in funding and providing access to powerful network
 s. Industrialists like Henry Ford loved and promoted ideas at least close 
 to fascism. German\, Italian\, and Austrian counterparts funded Hitler and
  Mussolini. And it is not that they did it because they did not understand
  the fascist leader’s yearning – it was because they shared and loved thei
 r aims and violence.\n\nIn Futurism\, one of the often overlooked roots of
  fascism\, and its Manifesto the enemies and societal goals are proclaimed
  crystal clear: “We will glorify war — the only true hygiene of the world 
 — militarism\, patriotism\, the destructive gesture of anarchist\, the bea
 utiful Ideas which kill\, and the scorn of woman.“\n\nAfter WWII most of t
 he people believing in dominating others by force and eugenics lived on\, 
 they and their cronies had slaughtered millions and destroyed whole social
  movements were opposing them. These people warning us about authoritarian
  prophets of doom and concentration camps are still missing.\n\nIn the pos
 t-war time ideas of authoritarianism met a new player: Cybernetics\, the b
 elieve in a future\, where all problems will be solved through technology 
 and we are “All Watched Over by Machines of Loving Grace” (Richard Brautig
 am\, 1967). The ideas split\, merged\, and melted into new beliefs and qua
 si-religions. Into something that is called “Cyber-Libertarianism” by Davi
 d Golumbia or “TESCREAL” by Émile P. Torres and Timnit Gebru.\n\nThis talk
  will address an aspect that is often missing in analyses: What kind of br
 eeding ground is it where ideas of fascism hatches best? And how can we st
 op iFascism instead of participating in it?\n\nFurthermore\, as being sort
 ed by machines is not everyone's secret dream\, ways to stop iFascism will
  be provided.\n\nBecause we are more\, we care for people in need – and we
  are the chaos!\n

DESCRIPTION:Building electronics has never been easier\, cheaper\, or more 
 accessible than the last few years. It's also becoming a precious skill in
  a world where commercially made electronics are the latest victim of ensh
 ittification and vibe coding. And yet\, while removing technical and finan
 cial barriers to building things\, we've not come as far as we should have
  in removing social barriers. The electronics and engineering industry and
  the cultures around them are hostile to newcomers and self-taught practit
 ioners\, for no good reason at all. I've been teaching advanced electronic
 s manufacturing skills to absolute beginners for a decade now\, and they'v
 e consistently succeeded at acquiring them. I'm here to tell you why it's 
 not as hard as it seems\, how to get into it\, and why more people who thi
 nk they can't should try.\nElectronics is easier and more fun to get into 
 than it's ever been before. All the tools and resources are easily accessi
 ble and super cheap or free. There's an enormous amount of things to build
  from and build on.\n\nIt's also never been more important to be able to b
 uild and understand electronics\, as assholes running corporations are was
 ting their workers' unpaid overtime on making all the electronics in our l
 ives shittier\, more full of ads\, slop\, and spyware\, and more frustrati
 ng to use. Encountering a device that works for you instead of against you
  is a breath of fresh air. Building one is an act of resistance and power.
  Not depending on the whims of corporate assholes is freedom.\n\nHowever\,
  the culture around electronics and the electronics industry is one of exc
 lusion and gatekeeping. It doesn't need to be. It would be stupidly easy t
 o make things better\, and we should. I've been teaching absolute beginner
 s advanced electronics manufacturing skills for many years now. It's absol
 utely shocking how much more diverse the people who I teach are compared t
 o the industry. The "hardware is hard" meme is true in some cases but toxi
 c when worn as a badge of pride or a warning to people attempting it.\n\nI
  will tell you why designing and building electronics is not nearly as har
 d as it seems\, how it's almost never been easier to get into it\, and why
  it's very important that people who think or have been told they can't do
  it should be doing more of it. I'll tell you my experiences of what build
 ing devices is like\, show and tell a few useful skills\, and tell the sto
 ry of how trying to prove someone wrong on the internet turned into a deca
 de of teaching people with zero experience how to handle the most complex 
 electronic components at all sorts of community events.\n

DESCRIPTION:Despite how widely used the ESP32 is\, its Bluetooth stack rema
 ins closed source. Let’s dive into the low-level workings of a proprietary
  Bluetooth peripheral. Whether you are interested in reverse engineering\,
  Bluetooth security\, or just enjoy poking at undocumented hardware\, this
  talk may inspire you to dig deeper.\nThe ESP32 has become an ubiquitous p
 latform in the hacker and maker communities\, powering everything from bad
 ges and sensors to mesh networks and custom routers. While its Wi-Fi stack
  has been the subject of previous reverse engineering efforts\, its Blueto
 oth subsystem remains largely undocumented and closed source despite being
  present in millions of devices.\n\nThis talk presents a reverse engineeri
 ng effort to document Espressif’s proprietary Bluetooth stack\, with a foc
 us on enabling low-level access for researchers\, security analysts\, and 
 developers to improve existing affordable and open Bluetooth tooling.\n\nT
 he presentation covers the reverse engineering process itself\, techniques
  and the publication of tooling to simplify the process of peripheral mapp
 ing\, navigating broken memory references and symbol name recovery.\n\nThe
  core of the talk focuses on the internal workings of the Bluetooth periph
 eral. The reverse engineering effort led to the discovery of the periphera
 l architecture\, it’s memory regions\, interrupts and a little bit of info
 rmation about other related peripherals.\n\nBy publishing open tooling\, S
 VD files and other documentation\, this work aims to empower researchers\,
  hackers\, and developers to build custom Bluetooth stacks\, audit existin
 g ones\, and repurpose the ESP32 for novel applications. This may interest
  you if you care about transparency\, low-level access\, and collaborative
  tooling.\n

DESCRIPTION:While trying to apply fault injection to the AMD Platform Secur
 ity Processor with unusual (self-imposed) requirements/restrictions\, it w
 ere software bugs which stopped initial glitching attempts. Once discovere
 d\, the software bug was used as an entry to explore the target\, which in
  turn lead to uncovering (and exploiting) more and more bugs\, ending up i
 n EL3 of the most secure core on the chip.\nThis talk is about the story o
 f trying to glitch the AMD Platform Security Processor\, then accidentally
  discovering several bugs and getting a good look inside the target\, befo
 re returning to trying to hammer it with novel physical strategies.\n# BAC
 KSTORY\n---------------\nSo here is the backstory of how it all started:\n
 - I bought a commercial gaming console\n- Then bought a VR headset (for th
 is console) because of exclusive game\n- But also wanted to play beatsaber
 \n- I could\, but builtin song selection was very limited\n- Custom songs 
 exist (for example on steam)\, but not for this console\n- I didn't want t
 o buy a second headset for steam\n  That's when i decided i want to hack t
 his console so that i can port community created customs songs to the cons
 ole and play them there with the VR headset i already have.\n\nInitially s
 tarting with an approach similar to the usual "entrypoint through browser"
 \, then go for kernel and call it a day\, but quickly annoying hurdles blo
 cked my way. For one\, the Hypervisor makes your live just miserable with 
 it's execute only kernel text blind exploitation. Other issues were that o
 ne needs to be on latest version to download the game\, which exists only 
 as digital purchase title\, preventing me to share my efforts with others 
 even if i can get it working on my console.\nThough\, what finally put the
  nail in the coffin was when porting a kernel zeroday to the console faile
 d because of heavy sandboxing\, unreachable syscalls or even entirely stri
 pped kernel functions. \nSome may call it "skill issue". Anyways\, that's 
 when i was full of it and decided to bring this thing down for good.  \nEv
 erybody does glitching nowadays and according to rumors people did have su
 ccess on this thing with glitching before\, so how hard can it really be\,
  right?\n\nSo the question became: Is it possible to build a modchip\, whi
 ch glitches the board and lets me play beatsaber custom songs?  \nStuff li
 ke that has been done on other consoles before (minus the beatsaber part :
 P)\n\nTurns out that when manufacturing produces chips with broken GPUs\, 
 they are sold as spinoff desktop mainboards (with disabled GPU) rather tha
 n thrown away. Which is great\, because those mainboards are much cheaper\
 , especially if you buy broken spinoff mainboards on ebay.\n\nSo on the jo
 urney to beatsaber custom songs\, breaking this desktop mainboard became a
  huge chunk of the road. Because if i can glitch this and build a modchip 
 for it\, surely i can also do it for the console\, right? I mean it's the 
 exact same SoC afterall! \nBack when i started i didn't know i would be ab
 out to open pAMDoras box and discover so many bugs and hacks.\n\n# Actual 
 talk description\n---------------\n**Disclaimer: This is not a console hac
 king talk!**  \nThis talk is gonna be about breaking nearly every aspect o
 f the AMD Platform Security Processor of the desktop mainboard with the sa
 me SoC as the console. While certainly usefuly for _several_  other AMD ta
 rgets\, unfortunately not every finding can directly be ported to the cons
 ole. Still\, it remains very useful nonetheless!\n\nNote: The final goal o
 f custom songs on beatsaber has not been reached yet\, this talk is presen
 ting the current state of things.\n\nIn this talk you'll be taken on a rid
 e on how everything started and how almost every aspect of the chip was br
 oken. How bugs were discovered\, what strategies were used to move along. 
  \nNot only will several novel techniques be presented for applying existi
 ng physical attacks to targets where those couldn't really be applied befo
 re\, but also completely new approaches are shared which bring a whole dif
 ferent perspective on glitching despite having lots of capacitors (which w
 e don't really want to remove) and extremely powerfull mosfets (which smoo
 th out crowbar attempts in a blink of an eye).\n\nBut that's not all!  \nW
 hile trying to perform physical attacks on the hardware\, the software wou
 ld just start falling apart by itself. Which means\, at least **6 unpatcha
 ble\\* bugs** were discovered\, which are gonna be presented in the talk a
 longside with **5 zero-day exploits**. Getting EL3 code execution on the m
 ost secure core inside AMDs SoC? No Problem! \nApart from just bugs and ex
 ploits\, many useful techniques and discovery strategies are shared which 
 will provide an excellent knowedgle base and attack inspiration for follow
 ing along or going for other targets.\n

DESCRIPTION:The Deutschlandticket was the flagship transport policy of the 
 last government\, rolled out in an impressive timescale for a political pr
 oject\; but this speed came with a cost - a system ripe for fraud at an in
 dustrial scale.\n\nGerman public transport is famously decentralised\, wit
 h thousands of individual companies involved in ticketing and operations. 
 Unifying all of these under one national\, secure\, system has proven a ch
 allenge too far for politicians. The end result: losses in the hundreds of
  millions of Euros\, compensated to the transport companies from state and
  federal budgets to keep the system afloat\, and nobody willing to take re
 sponsibility.\n\nThis talk will cover the political\, policy\, and technic
 al mistakes that lead to this mess\; how we can learn from these mistakes\
 ; and what we can do to ensure the Deutschlandticket has a viable future.\
 nAt last years Congress Q presented [a deep-dive into the technical detail
 s of train ticketing](https://media.ccc.de/v/38c3-what-s-inside-my-train-t
 icket) and its [Zügli](https://zügli.app) platform for this\; since then\,
  things have gone rather out of hand. The little side-project for looking 
 into the details of train tickets turned into a full-time project for dete
 cting ticketing fraud. This talk details an executive summary of the madne
 ss that has been the past year\, and how we accidentally ended up in natio
 nal and international politics working to secure the Deutschlandticket.\n\
 nShortly after last year's talk\, we were contacted about some *interestin
 g* looking tickets someone noticed\, issued by the Vetter GmbH Omnibus- un
 d Mietwagenbetrieb - or so they claimed to be. These were normal Deutschla
 ndtickets\, but with a few weird mistakes in them. At first\, we thought n
 othing much of it\; mistakes happen. But\, on further investigation\, thes
 e turned out to not be legitimate tickets at all\, but rather from a fraud
 ulent website by the name of d-ticket.su\, using the private signing key o
 btained under suspicious circumstances. How exactly this key came into the
  wrong hands remains unclear\, but we present the possible explanations fo
 r how this could've happened\, how many responsible have been thoroughly u
 ncooperative in getting to the bottom of this\, and how the supporting sys
 tems and processes of the Deutschlandticket were unable to cope with this 
 situation.\n\nParallel to this\, another fraud has been draining the trans
 port companies of their much-needed cash: SEPA Direct Debit fraud. Often\,
  a direct debit payment can be setup online with little more than an IBAN 
 and ticking a box\; and most providers of the Deutschlandticket offer an o
 ption to pay via direct debit. Fraudsters have noticed this\, and mass pur
 chase Deutschlandtickets with invalid or stolen IBANs before flipping them
  for a discounted price on Telegram\; made easier because most transport c
 ompanies issue a ticket immediately\, before the direct debit has been ful
 ly processed. The supporting systems of the Deutschlandticket in many case
 s don't even provide for the revocation of such tickets. We will detail th
 e hallmarks of this fraud\, how transport companies can work to prevent it
 \, and how we tracked down the fraudsters by their own careless mistakes.\

DESCRIPTION:Might contain zerodays. https://gpg.fail/\n\nFrom secure commun
 ications to software updates: PGP implementations such as *GnuPG* ubiquito
 usly relied on to provide cryptographic assurances. Many applications from
  secure communications to software updates fundamentally rely on these uti
 lities.\nSince these have been developed for decades\, one might expect ma
 ture codebases\, a multitude of code audit reports\, and extensive continu
 ous testing.\nWhen looking into various PGP-related codebases for some per
 sonal use cases\, we found these expectations not met\, and discovered mul
 tiple vulnerabilities in cryptographic utilities\, namely in *GnuPG*\, *Se
 quoia PGP*\, *age*\, and *minisign*.\nThe vulnerabilities have implementat
 ion bugs at their core\, for example in parsing code\, rather than bugs in
  the mathematics of the cryptography itself. A vulnerability in a parser c
 ould for example lead to a confusion about what data was actually signed\,
  allowing attackers without the private key of the signer to swap the plai
 n text. As we initially did not start with the intent of conducting securi
 ty research\, but rather were looking into understanding some internals of
  key management and signatures for personal use\, we also discuss the proc
 ess of uncovering these bugs. Furthermore\, we touch on the role of the Op
 enPGP specification\, and the disclosure process.\nBeyond the underlying m
 athematics of cryptographic algorithms\, there is a whole other layer of i
 mplementation code\, assigning meaning to the processed data. For example\
 , a signature verification operation both needs robust cryptography **and*
 * assurance that the verified data is indeed the same as was passed into t
 he signing operation. To facilitate the second part\, software such as *Gn
 uPG* implement parsing and processing code of a standardized format. Espec
 ially when implementing a feature rich and evolving standard\, there is th
 e risk of ambivalent specification\, and classical implementation bugs.\n\
 nThe impact of the vulnerabilities we found reaches from various signature
  verification bypasses\, breaking encryption in transit and encryption at 
 rest\, undermining key signatures\, to exploitable memory corruption vulne
 rabilities.\n

DESCRIPTION:Seit jetzt schon vier Jahren droht aus der EU die Chatkontrolle

 , vor allem im Hintergrund\, passiert ist. Wir nehmen die Position der Bun

 , die auf EU-Ebene vor uns liegen.\nDie Chatkontrolle liest sich mehr wie 
 eine tragische Komödie\, als ein Gesetzgebungsverfahren. Nach dem dramatur

 der Rebellen zu werfen. \nMarkus Reuter und khaleesi haben den Gesetzgebun

DESCRIPTION:Almost everyone has a household appliance at home\, whether it'
 s a washing machine\, dishwasher\, or dryer. Despite their ubiquity\, litt
 le is publicly documented about how these devices actually work or how the
 ir internal components communicate. This talk takes a closer look at propr
 ietary bus systems\, hidden diagnostic interfaces\, and approaches to clou
 d-less integration of appliances from two well-known manufacturers into mo
 dern home automation systems.\nModern home appliances may seem simple from
  the outside\, but inside they contain complex electronic systems\, propri
 etary communication protocols\, and diagnostic interfaces rarely documente

  reverse-engineering these systems: from analyzing appliance control board
 s and internal communication buses to decompiling and modifying firmware t
 o better understand device functionality.\n\nWe'll also look at the securi
 ty mechanisms designed to protect diagnostic access and firmware readout\,
  and how these protections can be bypassed to enable deeper insight into d
 evice operation. Finally\, this talk will demonstrate how the results of t
 his research can be used to integrate even legacy home appliances into pop

DESCRIPTION:Bluetooth headphones and earbuds are everywhere\, and we were w
 ondering what attackers could abuse them for. Sure\, they can probably do 
 things like finding out what the person is currently listening to. But wha
 t else? During our research we discovered three vulnerabilities (CVE-2025-
 20700\, CVE-2025-20701\, CVE-2025-20702) in popular Bluetooth audio chips 
 developed by Airoha. These chips are used by many popular device manufactu
 rers in numerous Bluetooth headphones and earbuds.\n\nThe identified vulne
 rabilities may allow a complete device compromise. We demonstrate the imme
 diate impact using a pair of current-generation headphones. We also demons
 trate how a compromised Bluetooth peripheral can be abused to attack paire
 d devices\, like smartphones\, due to their trust relationship with the pe
 ripheral.\n\nThis presentation will give an overview over the vulnerabilit
 ies and a demonstration and discussion of their impact. We also generalize
  these findings and discuss the impact of compromised Bluetooth peripheral
 s in general. At the end\, we briefly discuss the difficulties in the disc
 losure and patching process. Along with the talk\, we will release tooling
  for users to check whether their devices are affected and for other resea
 rchers to continue looking into Airoha-based devices.\n\nExamples of affec
 ted vendors and devices are Sony (e.g.\, WH1000-XM5\, WH1000-XM6\, WF-1000
 XM5)\, Marshall (e.g. Major V\, Minor IV)\, Beyerdynamic (e.g. AMIRON 300)
 \, or Jabra (e.g. Elite 8 Active).\nAiroha is a vendor that\, amongst othe
 r things\, builds Bluetooth SoCs and offers reference designs and implemen
 tations incorporating these chips. They have become a large supplier in th
 e Bluetooth audio space\, especially in the area of True Wireless Stereo (
 TWS) earbuds. Several reputable headphone and earbud vendors have built pr
 oducts based on Airoha’s SoCs and reference implementations using Airoha’s
  Software Development Kit (SDK).\n\nDuring our Bluetooth Auracast research
  we stumbled upon a pair of these headphones. During the process of obtain
 ing the firmware for further research we initially discovered the powerful
  custom Bluetooth protocol called *RACE*. The protocol provides functional
 ity to take full control of headphones. Data can be written to and read fr
 om the device's flash and RAM.\n\nThe goal of this presentation is twofold
 . Firstly\, we want to inform about the vulnerabilities. It is important t
 hat headphone users are aware of the issues. In our opinion\, some of the 
 device manufacturers have done a bad job of informing their users about th
 e potential threats and the available security updates. We also want to pr
 ovide the technical details to understand the issues and enable other rese
 archers to continue working with the platform. With the protocol it is pos
 sible to read and write firmware. This opens up the possibility to patch a
 nd potentially customize the firmware.\n\nSecondly\, we want to discuss th
 e general implications of compromising Bluetooth peripherals. As smart pho
 nes are becoming increasingly secure\, the focus for attackers might shift
  to other devices in the environment of the smart phone. For example\, whe
 n the Bluetooth Link Key\, that authenticates a Bluetooth connection betwe
 en the smart phone and the peripheral is stolen\, an attacker might be abl
 e to impersonate the peripheral and gain its capabilities.\n

DESCRIPTION:OpenAutoLab\, an open source machine\, that is capable of proce
 ssing contemporary color and black-and-white films for analogue photograph
 y\, is being presented here. It made its first public appearance at 37C3 a
 nd was already seen there in action\, but had no organized talk or proper 
 presentation. Now it is better documented\, waits to be built by more peop
 le and to be further developed by the community.\nThis talk is about motiv
 ation behind developing OpenAutoLab and about the technical decisions made
  during it. It is argued that any dedicated film photographer is able to g
 et one built.\nThe presentation starts with a short overview of analogue p
 hotography processes and motivation of some photographers to shoot film in
 stead of using contemporary digital technology.\nIt covers ways to process
  the film starting from least involved\, such as sending to specialized la
 boratory\, and possible motivation to get a processing machine.\nExisting 
 film processors are described with their features and deal-breakers for an
  end-user in 2025.\nThen the history of developing OpenAutoLab is given\, 
 together with important design decisions made during development and why a
 lternative solutions were discarded.\nIn the end the process of building t
 he machine (and sourcing the needed parts) is given with some motivation t
 owards changing it to fit the needs of an individual photographer.\n

DESCRIPTION:Reports of GNSS interference in the Baltic Sea have become almo
 st routine — airplanes losing GPS\, ships drifting off course\, and timing
  systems failing. But what happens when a group of engineers decides to bu
 ild a navigation system that simply *doesn’t care* about the jammer?\n\nSi
 nce 2017\, we’ve been developing **R-Mode**\, a terrestrial navigation sys
 tem that uses existing radio beacons and maritime infrastructure to provid
 e independent positioning — no satellites needed. In this talk\, we’ll sha
 re our journey from an obscure research project that “nobody needs” to a s
 ystem now seen as crucial for resilience and sovereignty. Expect technical
  insights\, field stories from ships in the Baltic\, and reflections on wh
 at it means when a civilian backup system suddenly attracts military inter
 est.\nSince 2017\, our team at DLR and partners across Europe have been wo
 rking on an alternative to satellite navigation: **R-Mode**\, a backup sys
 tem based on terrestrial transmitters. Our main testbed spans the Baltic S
 ea — a region now infamous for GNSS jamming and spoofing.\n\nWe’ll start b
 y showing what GNSS interference actually means in practice: aircraft losi
 ng navigation data\, ships switching to manual control\, and entire region
 s facing timing outages — such as the recent disruption of telecommunicati
 ons in Gdańsk during Easter 2025.\n\nThen we’ll take you behind the scenes
  of building R-Mode: designing signals that can coexist with legacy system
 s\, installing transmitters along the coast\, and testing shipborne receiv
 ers in rough conditions. We’ll share personal moments — like the first tim
 e we received a stable position fix in the middle of the Baltic.\n\nFinall
 y\, we’ll talk about perception and politics: how a “research curiosity” b
 ecame a critical infrastructure project\, why ESA now wants to build a *sa
 tellite* backup (with the same vulnerabilities)\, and how it feels when yo
 ur civilian open-source navigation system suddenly becomes strategically r
 elevant.\n

DESCRIPTION:FreeBSD’s jail mechanism promises strong isolation—but how stro
 ng is it really?\nIn this talk\, we explore what it takes to escape a comp
 romised FreeBSD jail by auditing the kernel’s attack surface\, identifying
  dozens of vulnerabilities across exposed subsystems\, and developing prac
 tical proof-of-concept exploits. We’ll share our findings\, demo some real
  escapes\, and discuss what they reveal about the challenges of maintainin
 g robust OS isolation.\nFreeBSD’s jail feature is one of the oldest and mo
 st mature OS-level isolation mechanisms in use today\, powering hosting en
 vironments\, container frameworks\, and security sandboxes. But as with an
 y large and evolving kernel feature\, complexity breeds opportunity. This 
 research asks a simple but critical question: If an attacker compromises r
 oot inside a FreeBSD jail\, what does it take to break out?\n\nTo answer t
 hat\, we conducted a large-scale audit of FreeBSD kernel code paths access
 ible from within a jail. We systematically examined privileged operations\
 , capabilities\, and interfaces that a jailed process can still reach\, hu
 nting for memory safety issues\, race conditions\, and logic flaws. The re
 sult: roughly 50 distinct issues uncovered across multiple kernel subsyste
 ms\, ranging from buffer overflows and information leaks to unbounded allo
 cations and reference counting errors—many of which could crash the system
  or provide vectors for privilege escalation beyond the jail.\n\nWe’ve dev
 eloped proof-of-concept exploits and tools to demonstrate some of these vu
 lnerabilities in action. We’ve responsibly disclosed our findings to the F
 reeBSD security team and are collaborating with them on fixes. Our goal is
 n’t to break FreeBSD\, but to highlight the systemic difficulty of maintai
 ning strict isolation in a large\, mature codebase.\n\nThis talk will pres
 ent our methodology\, tooling\, and selected demos of real jail escapes. W
 e’ll close with observations about kernel isolation boundaries\, lessons l
 earned for other OS container systems\, and a call to action for hardening
  FreeBSD’s jail subsystem against the next generation of threats.\n

DESCRIPTION:Trusted Execution Environments (TEEs) based on ARM TrustZone fo
 rm the backbone \nof modern Android devices' security architecture. The wo
 rd "Trusted" in \nthis context means that **you**\, as in "the owner of th
 e device"\, don't \nget to execute code in this execution environment. Eve
 n when you unlock \nthe bootloader and Magisk-root your device\, only vend
 or-signed code will\n be accepted by the TEE. This unfortunate setup limit
 s third-party \nsecurity research to the observation of input/output behav
 ior and static\n manual reverse engineering of TEE components.\n\nIn this 
 talk\, we take you with us on our journey to regain power over \nthe highe
 st privilege level on Xiaomi devices. Specifically\, we are \ntargeting th
 e Xiaomi Redmi 11s and will walk through the steps necessary\n to escalate
  our privileges from a rooted user space (N-EL0) to the \nhighest privileg
 e level in the Secure World (S-EL3). We will revisit old\n friends like Tr
 usted Application rollback attacks and GlobalPlatform's \ndesign flaw\, an
 d introduce novel findings like the literal fiasco you \ncan achieve when 
 you're introducing micro kernels without knowing what \nyou're doing. In d
 etail\, we will elaborate on the precise exploitation \nsteps taken and mi
 tigations overcome at each stage of our exploit chain\,\n and finally demo
  our exploits on stage.\n\nRegaining full control over our devices is the 
 first step to deeply \nunderstand popular TEE-protected use cases includin
 g\, but not limited \nto\, mobile payment\, mobile DRM solutions\, and the
  mechanisms protecting your biometric \nauthentication data.\nWe present n
 ovel insights into the current state of TEE security on \nAndroid focusing
  on two widespread issues: missing TA rollback \nprotection and a type con
 fusion bug arising from the GlobalPlatform TEE \nInternal Core API specifi
 cation.\nOur results demonstrate that these issues are so widespread that 
 on most\ndevices\, attackers with code execution at N-EL1 (kernel) have a 
 buffet \nof n-days to choose from to achieve code execution at S-EL0 (TA).
 \n\nFurther\, we demonstrate how these issues can be weaponized to fully \
 ncompromise an Android device. We discuss how we exploit CVE-2023-32835\, 
 a\ntype confusion bug in the keyinstall TA\, on a fully updated Xiaomi \nR
 edmi Note 11.\nWhile the keyinstall TA shipped in the newest firmware vers
 ion is not \nvulnerable anymore\, the vulnerability remains triggerable du
 e to missing\nrollback protections.\n\nTo further demonstrate how powerful
  code execution as a TA is\, we'll \nexploit a vulnerability in the BeanPo
 d TEE (used on Xiaomi Mediatek \nSoCs)\, to achieve code execution at S-EL
 3. Full privilege escalations in\nthe TEE are rarely seen on stage\, and w
 e are targeting the BeanPod TEE \nwhich is based on the Fiasco micro kerne
 l. This target has never been \npublicly exploited\, to the best of our kn
 owledge.\n\nOur work empowers security researchers by demonstrating how to
  regain control over \nvendor-locked TEEs\, enabling deeper analysis of cr
 itical security \nmechanisms like mobile payments\, DRM\, and biometric au
 thentication.\n

DESCRIPTION:The spyware attack targeting WhatsApp\, disclosed in August as 
 an in-the-wild exploit\, garnered significant attention. By simply knowing
  a victim's phone number\, an attacker could launch a remote\, zero-intera
 ction attack against the WhatsApp application on Apple devices\, including
  iPhones\, iPads\, and Macs. Subsequent reports indicated that WhatsApp on
  Samsung devices was also targeted by similar exploits.\nIn this presentat
 ion\, we will share our in-depth analysis of this attack\, deconstructing 
 the 0-click exploit chain built upon two core vulnerabilities: CVE-2025-55
 177 and CVE-2025-43300. We will demonstrate how attackers chained these vu
 lnerabilities to remotely compromise WhatsApp and the underlying iOS syste
 m without any user interaction or awareness. Following our analysis\, we s
 uccessfully reproduced the exploit chain and constructed an effective PoC 
 capable of simultaneously crashing the target application on iPhones\, iPa
 ds\, and Macs. Finally\, we will present our analysis of related vulnerabi
 lities affecting Samsung devices (such as CVE-2025-21043) and share how th
 is investigation led us to discover additional\, previously unknown 0-day 
 vulnerabilities.\nIn August 2025\, it attracted significant attention when
  Apple patched CVE-2025-43300\, a vulnerability reportedly exploited in-th
 e-wild to execute "extremely sophisticated attack against specific targete
 d individuals”. A week later\, WhatsApp issued a security advisory\, revea
 ling the fix for a critical vulnerability\, CVE-2025-55177\, which was als
 o exploited in-the-wild. Strong evidence indicated that these two vulnerab
 ilities were chained together\, enabling attackers to deliver a malicious 
 exploit via WhatsApp to steal data from a user's Apple device\, all withou
 t any user interaction.\n\nTo deconstruct this critical and stealthy in-th
 e-wild 0-click exploit chain\, we will detail our findings in several part
 s:\n1. WhatsApp 0-Click Attack Vector (CVE-2025-55177). We will describe t
 he 0-click attack surface we identified within WhatsApp. We will detail th
 e flaws in WhatsApp's message handling logic for "linked devices\," which 
 stemmed from insufficient validation\, and demonstrate how an attacker cou
 ld craft malicious protocol messages to trigger the vulnerable code path.\
 n2. iOS Image Parsing Vulnerability (CVE-2025-43300). The initial exploit 
 allows an attacker to force the target's WhatsApp to load arbitrary web co
 ntent. We will then explain how the attacker leverages this by embedding a
  malicious DNG image within a webpage to trigger a vulnerability in the iO
 S image parsing library. We will analyze how the RawCamera framework handl
 es the parsing of DNG images\, and pinpoint the resulting OOB vulnerabilit
 y.\n3. Rebuilding the Chain: From Vulnerability to PoC. In addition\, we w
 ill then walk through our process of chaining these two vulnerabilities\, 
 constructing a functional Proof-of-Concept (PoC) that can simultaneously c
 rash the WhatsApp application on target iPhones\, iPads\, and Macs.\n\nBey
 ond Apple: The Samsung Connection (CVE-2025-21043). Samsung's September se
 curity bulletin patched CVE-2025-21043\, an out-of-bounds write vulnerabil
 ity in an image parsing library reported by the Meta and WhatsApp security
  teams. This vulnerability was also confirmed to be exploited in-the-wild.
  While an official WhatsApp exploit chain for Samsung devices has not been
  publicly detailed\, we will disclose our findings on this related attack.
  Finally\, we will share some unexpected findings from our investigation\,
  including the discovery of several additional\, previously undisclosed 0-
 day vulnerabilities.\n

 ntroduces a forthcoming HackLab designed to foster collaborative developme
 nt of open-source tools addressing digital authoritarianism\, surveillance
  capitalism\, propaganda infrastructures\, and ideological warfare.\nIn th
 is talk\, media artist and curator Helena Nikonole presents her work at th
 e intersection of art\, activism\, and tactical technology — including int
 erventions into surveillance systems\, wearable mesh networks for off-grid
  communication\, and AI-generated propaganda sabotage.\n\nFeaturing projec
 ts like Antiwar AI\, the 868labs initiative\, and the curatorial project D
 igital Resistance\, the talk explores how art can do more than just commen
 t on sociotechnical systems — it can interfere\, infiltrate\, and subvert 
 them.\n\nThis is about prototypes as politics\, networked interventions as
  civil disobedience\, and media hacks as tools of strategic refusal. The t
 alk asks: what happens when art stops decorating crisis and starts debuggi
 ng it?\n\nThe talk will also introduce an upcoming HackLab initiative — a 
 collaboration-in-progress that brings together artists\, hackers\, and act
 ivists to develop open-source tools for disruption\, resilience\, and coll
 ective agency — and invites potential collaborators to get involved.\n

DESCRIPTION:Have you ever wondered how the chips and algorithms that made a
 ll those electronic music hits work? Us too!\n\nAt The Usual Suspects we c
 reate open source emulations of famous music hardware\, synthesizers and e
 ffect units. After releasing some emulations of devices around the Motorol
 a 563xx DSP chip\, we made further steps into reverse engineering custom s
 ilicon chips to achieve what no one has done before: a real low-level emul
 ation of the JP-8000. This famous synthesizer featured a special "SuperSaw
 " oscillator algorithm\, which defined an entire generation of electronic 
 and trance music. The main obstacle was emulating the 4 custom DSP chips t
 he device used\, which ran software written with a completely undocumented
  instruction set. In this talk I will go through the story of how we overc
 ame that obstacle\, using a mixture of automated silicon reverse engineeri
 ng\, probing the chip with an Arduino\, statistical analysis of the opcode
 s and fuzzing. Finally\, I will talk about how we made the emulator run in
  real-time using JIT\, and what we found by looking at the SuperSaw code.\
 nThis talk is a sequel to my last year's talk "Proprietary silicon ICs and
  dubious marketing claims? Let's fight those with a microscope!"\, where I
  showed how I reverse engineered a pretty old device (1986) by looking at 
 microscope silicon pics alone\, with manual tracing and some custom tools.
  Back then I claimed that taking a look at a more modern device would be w
 ay more challenging\, due to the increased complexity.\n\nThis time\, in f
 act\, I've reverse engineered a much modern chip: the custom Roland/Toshib
 a TC170C140 ESP chip (1995). Completing this task required a different app
 roach\, as doing it manually would have required too much time. We used a 
 guided automated approach that combines clever microscopy with computer vi
 sion to automatically classify standard cells in the chip\, saving us most
  of the manual work.\nThe biggest win though came from directly probing th
 e chip: by exploiting test routines and sending random data to the chip we
  figured out how the internal registers worked\, slowly giving us insights
  about the encoding of the chip ISA. By combining those two approaches we 
 managed to create a bit-accurate emulator\, that also is able to run in re
 al-time using JIT.\n\nIn this talk I want to cover the following topics:\n
 - What I learned since my previous talk by looking at more complicated chi
 ps\n- Towards automating the silicon reverse engineering process\n- How to
  find and exploit test modes to understand how stuff works\n- How we trick
 ed the chips into spilling its own secrets\n- How the ESP chip works\, com
 pared to existing DSP chips\n- How the SuperSaw oscillator turned out to w
 ork\n

DESCRIPTION:Anfang der 90er brennen in der Schweiz die Asylheime. Nicht Ros
 tock oder Hoyerswerda\, sondern auch Chur\, Lotzwil und Konolfingen bei Be
 rn. Das ist die oft vergessene Welle rechtsextremen Terrors mitten in der 
 Schweiz.\nRechtsextreme Skinheadgruppen\, später Blood & Honour- und Hamme
 rskins-Strukturen\, traten offen auf\, organisierten Konzerte\, patrouilli
 erten in Gruppen durch Städte und agierten äusserst brutal. Die staatliche
  Reaktion blieb lange verhalten – Bagatellisierung\, Wegschauen\, fehlende
  Ermittlungen. Antifaschistische Organisation und Selbstschutz wurden dami
 t zur Notwendigkeit.\nParallel dazu entwickelte sich in Bern eine kraftvol
 le antirassistische Bewegung\, die weit über Szenepolitik hinausging. Währ
 end rechts motivierte Gewalt zunahm und Asylgesetzverschärfungen politisch
 e Mehrheiten fanden\, begann ein breiter gesellschaftlicher Widerstand\, g
 etragen von migrantischen Communities\, Gewerkschaften und linken Gruppen.
  In dieser Zeit fanden grosse Demonstrationen für die Antirassismusstrafno
 rm statt – ein Gesetz\, das damals hart umkämpft war und dessen Annahme er
 st durch massiven öffentlichen Druck möglich wurde. Gleichzeitig entstand 
 eine breite Sans-Papiers-Bewegung: Platzbesetzungen\, Kirchenasyle\, Strei

  Tausende Menschen ohne geregelten Status in der Schweiz leben und arbeite
 n.\nDie Kämpfe dieser Jahre zeigen deutlich\, dass antifaschistische und a

 assen\, als wäre es ein Typ mit Backing Track. Für mehr Musiker:innen hat 
 das Bier nicht gereicht. Sorry.\nWas kann man noch über Einschiss sagen\, 
 was nicht schon alle gesagt haben? Diese Einmannpunkband hat mehrere Hörer
 :innen erreicht\, indem er ihnen Fußbilder versprochen hat. Dieser kluge P
 R-Schachzug hat eine bis heute treue Fanbase gezwungen\, jede der beiden E
 Ps zu klauen. Einschiss macht Musik für die einfach gestrickten Leute\, di
 e am Montagmorgen denken: Scheisse\, gar keinen Bock auf Nazis.\n\nDas Liv
 e Set ist eine Tour de Force durch die seltener gespielten C- und D-Seiten
  auf einer vielsaitigen Gitarre mit teils unterschiedlichen aber immer häu
 figer auch eingängigen Texten zum Mitgrölen und Heiratsanträge machen. Das
  gute ist: selbst wenn es schlecht wird\, dauert es nur 30 minuten. Eine B
 ahnfahrt macht da länger schlechte Laune.\n

DESCRIPTION:\nWir\, ein paar Menschen aus dem Umfeld des Chaostreffs des c3

 Design entworfen. Zunächst nur für uns und … ach komm… wir machen ein paar
  mehr. \nAn Tag 0 waren alle PCBs weg!\nZum 38c3 gab es nicht nur eine Neu
 auflage im aktuellen Design sondern auch noch eine Nachproduktion vom 37c3
 . \nAn Tag 1 waren alle PCBs weg!\nZum 39c3 gibt es nun die dritte Auflage
  - wieder im aktuellen Congress-Design\, mit 3 Widerständen\, einem MOSfet
  und 8 RGB LEDs wird das Ganze mit einem Wemos D1 Mini zu einem leuchtende
 n\, blinkenden Erinnerungsstück an deinen (ersten?) Congress!\nWir haben L
 ötstationen\, helfende Hände aber leider nur begrenzt Platz und Zeit.\nWir
  werden verschiedene Vorbereitungsstufen vorhalten so dass jede und jeder 
 -unabhängig von der Löterfahrung- am Ende ein PCB zum leuchten bringen kan
 n.\nBitte meldet euch an damit wir planen können:\nkohlenpod@c3re.de\n\nDi
 e Kosten für die Hardware inkl. Wemos betragen ca. 5€ - es wäre nett wenn 
 ihr euch an den Kosten beteiligt - dies ist aber absolut kein Muss!\n\nP.S
 : wir haben auch noch eine kleine Menge an 37C3 und 38C3 PCBs nachbestellt
  - damit die Menschen die gerne sammeln die Chance haben alle PCBs zu beko
 mmen. Die sind übrigens untereinander kompatibel und können gestapelt werd

DESCRIPTION:\nAt the beginning of December\, the European Court of Justice 
 ruled that online marketplaces are liable for data protection violations c
 ommitted by their users\, regardless of whether they took timely action ag
 ainst them. The liability privilege for hosting providers does not apply t
 o violations of the GDPR. Online marketplaces and their users are jointly 
 responsible. Providers are therefore required to verify the identity of us
 ers and their content in advance. Does this spell the end for the Fedivers
 e? We take a look at the ruling together and discuss what it means for ins

DESCRIPTION:Typography is the art of arranging type to make written languag
 e legible\, readable\, and appealing when displayed. However\, for the neo
 phyte\, typography is mostly apprehended as the juxtaposition of character
 s displayed on the screen while for the expert\, typography means typeface
 \, scripts\, unicode\, glyphs\, ascender\, descender\, tracking\, hinting\
 , kerning\, shaping\, weigth\, slant\, etc. Typography is actually much mo
 re than the mere rendering of glyphs and involves many different concepts.
  If glyph rendering is an important part of the rendering pipeline\, it is
  nonetheless important to have a basic understanding of typography or ther
 e’s a known risk at rendering garbage on screen\, as it has been seen many
  times in games\, software and operating systems.\nText is everywhere in o
 ur modern digital life and yet\, no one really pay attention to how it is 
 rendered on a screen. Maybe this is a sign that problem has been solved. B
 ut it isn't. A few people are still looking at the best way to display tex
 t on any devices & any languages. This talk is based on a lesson I gave at
  SIGGRAPH  a few years ago (https://www.slideshare.net/slideshow/siggraph-
 2018-digital-typography/110385070) to explain rendering techniques and con

DESCRIPTION:Despite how it's often portrayed in blogs\, scientific articles
 \, or corporate test planning\, fuzz testing isn't a magic bug printer\; j
 ust saying "we fuzz our code" says nothing about how _effectively_ it was 
 tested. Yet\, how fuzzers and programs interact is deeply mythologised and
  poorly misunderstood\, even by seasoned professionals. This talk analyses
  a number of recent works and case studies that reveal the relationship be
 tween fuzzers\, their inputs\, and programs to explain _how_ fuzzers work.
 \nFuzz testing (or\, "fuzzing") is a testing technique that passes randoml
 y-generated inputs to a subject under test (SUT). This term was first coin
 ed in 1988 by Miller to describe sending random byte sequences to Unix uti
 lities (1)\, but was arguably preceded in 1971 by Breuer for fault detecti
 on in sequential circuits (2) and in 1972 by Purdom for parser testing by 
 generating sentences from grammars (3). Curiously\, they all exhibit diffe
 rent approaches for generating inputs based on knowledge about the SUT\, t
 hough none of them use feedback from the SUT to make decisions about new i
 nputs.\n\nFuzzing wasn't yet popular\, but industry was catching on. Betwe
 en the late 90s and 2013\, we see a number of strategies appear in industr
 y (4). Some had success with constraint solvers\, where they would observe
  runtime behavior or have knowledge about a target's structure to produce 
 higher quality inputs. Others operated in a different way\, by taking an e
 xisting input and tweaking it slightly ("mutating") to address the low-lik
 elihood of random generation to produce structured inputs. None was as suc
 cessful\, or as popular\, as American Fuzzy Lop\, or "AFL"\, released in 2
 013. This combined coverage observations for inputs (Ormandy\, 2007) with 
 concepts from evolutionary novelty search (5) into a tool which could\, fr
 om very few initial inputs\, _evolve_ over multiple mutations to find new\
 , untested code.\n\nDespite its power\, this advancement made it far more 
 difficult to understand how fuzzers even worked. Now all you had to do was
  point this tool at a program and it would start testing\, and the coverag
 e would go up\; users were now only responsible for writing "harnesses"\, 
 code which processed fuzzer-produced inputs and sent them to the SUT. Thou
 gh there have been a few real advances to fuzzing since (or\, at least\, s
 trategies which combined previous methods more effectively)\, fuzzing rese
 arch has mostly deadended\, with new methods squeezing only minor improvem
 ents out of older ones. This\, and inadequate harness writing\, comes from
  this opaqueness in how fuzzers internally operate: without understanding 
 what these tools do from first principles\, there's no clear "right" and "
 wrong" way to do things because there is no mental model to test them agai
 nst.\n\nThis talk doesn't talk about new bugs\, new fuzzers\, or new harne
 ss generation tools. The purpose of this talk is to uncover mechanisms of 
 fuzzer input production in the context of different classes of SUT and har
 nesses thereon\, highlighting recent papers which have clarified our under
 standing of how fuzzers and SUTs interact. By the end\, you will have a be
 tter understanding of _why_ modern fuzzers work\, _what_ their limitations
  are\, and _how_ you can write better fuzzers and harnesses yourself.\n\n(

DESCRIPTION:Die Legalisierung des Online-Glücksspiels in Deutschland im Jah
 r 2021 und die zunehmende Normalisierung von Glücksspiel und Sportwetten i
 n den Medien haben ein Umfeld geschaffen\, in welchem Glücksspielprodukte 
 leichter zugänglich und gesellschaftlich stärker akzeptiert sind als je zu
 vor. Diese weit verbreitete Exposition birgt erhebliche Risiken für vulner
 able Personen\, insbesondere da die Grenzen zwischen Spielen und Glücksspi
 el zunehmend verwischen. Seit einiger Zeit ist beispielsweise ein deutlich
 er Anstieg von Spielen zu beobachten\, die Glücksspiel-ähnliche Items wie 
 Loot-Boxen beinhalten. Komplexe Designmerkmale in elektronischen Glücksspi
 elprodukten\, z.B. Glücksspielautomaten und Online-Slots\, sind gezielt da
 rauf ausgerichtet\, Individuen zu verlängerten Spielsitzungen zu motiviere
 n\, um den Umsatz zu maximieren. Während Glücksspiel für viele Menschen ei
 ne Form der Unterhaltung darstellt\, kann das Spielverhalten bei manchen e
 skalieren und schwerwiegende Folgen für das Leben der Betroffenen haben. D
 ieser Vortrag wird Mechanismen in Glücksspielprodukten und Loot Boxen bele
 uchten und aufzeigen\, weshalb diese Merkmale das Suchtpotenzial fördern k
 önnen. Hierbei spielen Mechanismen des sogenannten Verstärkungslernens (en
 gl. Reinforcement Learning) eine Rolle\, die das menschliche Belohnungssys
 tem aktivieren\, also dopaminerge Bahnen\, welche an der Vorhersage von Be
 lohnungen beteiligt sind. Besonderes Augenmerk liegt auf dem Reinforcement
 -Learning\, einem Framework zur Modellierung von Lernen durch belohnungsba
 siertes Feedback\, welches sowohl in der Psychologie zur Beschreibung mens
 chlichen Lernens und Entscheidungsverhaltens als auch zur Optimierung von 
 Machine-Learning-Algorithmen eingesetzt wird. Im Vortrag werden auch Ergeb
 nisse aus eigener Forschung am Labor der Universität zu Köln vorgestellt. 
 Ziel ist es\, Mechanismen des Glücksspiels zu erklären\, sowie das Bewusst
 sein für potenzielle Schäden für Individuen und die Gesellschaft zu schärf
 en und die Notwendigkeit von Regulation sowie verantwortungsbewussten Desi
 gnpraktiken zu diskutieren.\nIn diesem Vortrag wird beleuchtet\, wie moder
 ne Glücksspielprodukte und glücksspielähnliche Spielmechaniken\, etwa Loot
 boxen\, gezielt psychologische und neurobiologische Lernprozesse ausnutzen
 \, um Umsatz durch längeres Spielen und stärkere Interaktion zu generieren
 . Im Fokus stehen dabei Mechanismen des Verstärkungslernens (Reinforcement
  Learning) und deren Zusammenspiel mit dem dopaminergen Belohnungssystem. 
 Anhand aktueller Forschungsergebnisse werden Designstrategien vorgestellt\
 , die das Suchtpotenzial von Glücksspielen erhöhen können. Ziel des Vortra
 gs ist es\, ein wissenschaftlich fundiertes Verständnis dieser Dynamiken z
 u vermitteln\, Risiken für Individuen und Gesellschaft aufzuzeigen und die
  Notwendigkeit von Regulierung und verantwortungsvollem Design zu diskutie
 ren.\n

DESCRIPTION:From the EU’s “Chat Control” to the UK’s age verification\, the
 re is a growing legislative momentum across jurisdictions to regulate the 
 Internet in the name of protecting children. The monstrosity of child sexu
 al abuse looms large in shaping how policymakers\, advocates\, and the pub
 lic understand the problem area of and propose solutions for detecting\, r
 eporting\, and removing harmful/illegal content. Children’s safety and adu
 lts’ privacy are thus pitted against each other\, deadlocked into an impas
 se. As technologists deeply concerned with safety and privacy\, where do w
 e go from here?\nThere is a path forward! Many\, in fact. But the impasse 
 framing seriously limits how policymakers\, technologists\, advocates\, an
 d our communities understand child sexual abuse (CSA). We need informed\, 
 principled\, and bold alternatives to policing-driven tech solutions like 
 client-side scanning and grooming classifiers. To effectively and humanely
  break the cycles of abuse that enables CSA in our communities\, we have t
 o think beyond criminalization. This talk will unpack how and why this imp
 asse framing exists\, how it constrains us from candidly engaging with the
  complexity of CSA. Drawing from scientific and clinical research and info
 rmed by transformative justice approaches\, I detail what CSA is\, how and
  why it happens offline and online\, and why the status quo of detection a
 nd criminalization does not work. Ultimately\, I argue that effective\, hu
 mane\, and collective interventions require protecting the safety and priv
 acy of all those harmed by CSA\, and that this creates a unique role for t
 echnologists to play.\n

DESCRIPTION:In August 2024\, Raspberry Pi released their newest MCU: The RP
 2350. Alongside the chip\, they also released the RP2350 Hacking Challenge
 : A public call to break the secure boot implementation of the RP2350. Thi
 s challenge concluded in January 2025 and led to five exciting attacks dis
 covered by different individuals.\n\nIn this talk\, we will provide a tech
 nical deep dive in the RP2350 security architecture and highlight the diff
 erent attacks. Afterwards\, we talk about two of the breaks in detail---ea
 ch of them found by one of the speakers. In particular\, we first discuss 
 how fault injection can force an unverified vector boot\, completely bypas
 sing secure boot. Then\, we showcase how double glitches enable direct rea
 dout of sensitive secrets stored in the one-time programmable memory of th
 e RP2350.\n\nLast\, we discuss the mitigation of the attacks implemented i
 n the new revision of the chip and the lessons we learned while solving th
 e RP2350 security challenge. Regardless of chip designer\, manufacturer\, 
 hobbyist\, tinkerer\, or hacker: this talk will provide valuable insights 
 for everyone and showcase why security through transparency is awesome.\nT
 he RP2350 is one of the first generally available microcontrollers with ac
 tive security-features against fault-injection such as glitch-detectors\, 
 the redundancy co-processor\, and other pieces to make FI attacks more dif
 ficult.\n\nBut security on paper often does not mean security in real-life
 . Luckily for us\, Raspberry Pi also ran the RP2350 Hacking Challenge: A p
 ublic bug bounty that has exactly these attacks in-scope. During the hacki
 ng challenge 5 different attacks were found on the secure-boot process - o
 ne of which was shown at 38C3 by Aedan Cullen.\n\nIn this talk\, we talk a
 bout all successful attacks - including laser fault-injection\, a reset gl
 itch\, and a double-glitch during execution of the bootrom - to show all t
 he different ways in which a chip can be attacked.\n\nWe also talk about t
 he awesomeness of an open security-ecosystem for chips: Raspberry Pi was v
 ery transparent on the findings\, and worked with researchers to improve t
 he new revision of the chip.\n

 ihr wichtigstes Kommunikationsmittel – auf unbestimmte Zeit.\n\nHier hört 
 ihr\, welche absurden Blüten das treibt. Von Bayern bis NRW haben Bundeslä
 nder inzwischen eigene IT-forensische Tools für ihre Behörden angeschafft\
 , um auf den Geräten nach “Indizien” für die Herkunft zu suchen. Sie setze
 n Methoden ein\, wie wir sie sonst aus Ermittlungsverfahren oder von Gehei
 mdiensten kennen – um die Geräte von Menschen zu durchsuchen\, die nichts 
 verbrochen haben.\n\nIm Vortrag zeige ich\, welche absurden Konsequenzen d
 as für die Betroffenen mit sich bringt\, welche Bundesländer an der trauri
 gen Spitze der Statistik stehen – und wie sich das Ganze in das Arsenal de
 r digitalen und sonstigen Repressionen von Geflüchteten einreiht.\n

DESCRIPTION:Wenn die Regierung sich nicht mehr an das eigene Recht gebunden
  fühlt\, markiert das nicht nur einen politischen Spurwechsel\, sondern di
 e Auffahrt auf den Highway to Trumpism. Zeit die Notbremse zu ziehen!\nNor
 malerweise trifft es in solchen Situationen immer zuerst diejenigen\, die 
 sich am wenigsten wehren können. Doch was passiert\, wenn genau diese Mens
 chen mit juristischen Werkzeugen bewaffnet werden\, um zurückzuschlagen?\n
 Anhand von über 100 Klagen afghanischer Schutzsuchender zeigen wir\, wie M
 inisterien das Bundesaufnahmeprogramm sabotieren\, Gerichte sie zurückpfei
 fen – und die Zivilgesellschaft zum letzten Schutzwall des Rechtsstaats wi
 rd. Und wir verraten\, warum sich Beamte im BAMF vielleicht lieber krankme
 lden sollten und welche anderen Möglichkeiten sie haben\, um nicht straffä
 llig zu werden.\n•	Versprochen ist versprochen und wird auch nicht gebroch
 en“ – das lernen wir schon als Kinder. Aber der Kindergarten ist schon lan
 ge her\, und Politiker*innen haben zwar oft das Auftreten eines Elefanten\
 , aber das Gedächtnis eines Goldfischs.\n•	Deswegen hätte die Bundesregier
 ung auch fast 2.500 Afghan*innen mit deutschen Aufnahmezusagen in Islamaba
 d „vergessen“\, die dort seit Monaten auf die Ausstellung ihrer deutschen 
 Visa warten\n•	Das Kalkül dahinter: Pakistan erledigt die Drecksarbeit und
  schiebt sie früher oder später ab\, Problem solved! - selbst wenn dabei M
 enschenleben auf dem Spiel stehen.\n•	Wie kann die Zivilgesellschaft die N
 otbremse ziehen\, wenn sich Regierung und Verwaltung nicht mehr an das eig
 ene Recht gebunden fühlen?\n•	Eine Möglichkeit: wir vernetzen die afghanis
 chen Familien mit Anwält*innen\, damit sie Dobrindt und Wadephul verklagen
  - und sie gewinnen! Die Gerichtsbeschlüsse sind eindeutig: Visa sofort er
 teilen – sonst Strafzahlungen! Inzwischen laufen über 100 Verfahren an vie
 r Verwaltungsgerichten\, weitere kommen täglich hinzu. \n•	Das dürfte nich
 t ganz das gewesen sein\, was die neue Bundesregierung meinte\, als sie im
  Koalitionsvertrag verkündete\, „freiwillige Aufnahmeprogramme so weit wie
  möglich zu beenden“. \nÜbersetzung der politischen Realitätsversion: Wenn
  es nach Dobrindt und dem Kanzler geht\, sollen möglichst gar keine Schutz
 suchenden aus Afghanistan mehr nach Deutschland kommen – rechtsverbindlich
 e Aufnahmezusagen hin oder her. Einreisen dürfen nur noch anerkannte Terro
 risten aus der Taliban-Regierung\, um hier in Deutschland die afghanischen
  Botschaften und Konsulate zu übernehmen\n•	Durch die Klagen konnten berei
 ts 78 Menschen einreisen\, etwa 80 weitere Visa sind in Bearbeitung – und 
 weitere werden vorbereitet.\n•	Doch wie in jedem Drehbuch gilt: The Empire
  strikes back! Die Regierung entwickelt laufend neue Methoden\, um Urteile
  ins Leere laufen zu lassen und Einreisen weiterhin zu blockieren.\n•	Will
 kommen im „Trumpismus made in Germany“.\n

DESCRIPTION:With PTP 1588\, AES67\, and SMPTE 2110\, we can transmit synchr
 onous audio and video with sub-millisecond latency over the asynchronous m
 edium Ethernet. But how do you make hundreds of devices agree on the exact
  same nanosecond on a medium that was never meant to care about time?\nPre
 cision Time Protocol (IEEE 1588) tries to do just that. It's the invisible
  backbone of realtime media standards like AES67 and SMPTE 2110\, propriet
 ary technologies such as Dante\, and even critical systems powering high-f
 requency trading\, cellular networks\, and electric grids.\nWhere even a f
 ew microseconds of drift can turn perfect sync into complete chaos.\nThis 
 talk takes a deep dive into the mysterious world of precise time distribut
 ion in large networks. We’ll start by exploring how PTP 1588 actually work
 s\, from announce\, sync\, and follow-up messages to delay measurements an
 d the magic of hardware timestamping. We’ll look at why PTP is critical fo
 r modern audio/video-over-IP standards like AES67 and SMPTE 2110\, and how
  they push Ethernet to its absolute temporal limits.\nAlong the way\, we’l
 l discover how transparent and boundary clocks fight jitter\, and why your
  switch’s buffer might secretly hate you. We will do live Wireshark dissec
 tions of real PTP traffic\, demos showing what happens when timing breaks\
 , and some hands-on hardware experiments with grandmasters and followers t
 rying to stay in sync.\nExpect packets\, graphs\, oscilloscopes\, crashing
  live demos and at least one bad joke about time travel.\n

DESCRIPTION:I successfully failed with a literature related project and acc
 identally built a ChatGPT detector. Then I spoke to the people who uploade
 d ChatGPT generated content on Wikipedia.\nIt began as a standard maintena
 nce project: I wanted to write a tool to find and fix broken ISBN referenc
 es in Wikipedia. Using the built-in checksum\, this seemed like a straight
 forward technical task. I expected to find mostly typos. But I also found 
 texts generated by LLMs. These models are effective at creating plausible-
 sounding content\, but (for now) they often fail to generate correct check
 sums for identifiers like ISBNs. This vulnerability turned my tool into an
  unintentional detector for this type of content. This talk is the story o
 f that investigation. I'll show how the tool works and how it identifies t
 his anti-knowledge. But the tech is only half the story. The other half is
  human. I contacted the editors who had added this undeclared AI content. 
 I will talk about why they did it and how the Wikipedians reacted and whet
 her "The End is Nigh" calls might be warranted.\n

DESCRIPTION:\nCADUS is currently active in war zones such as Ukraine\, Gaza
 \, and Sudan—but it all started backstage at a music festival.\nThe idea: 
 to rethink humanitarian aid\, beyond uniforms\, hierarchy\, and postcoloni
 al “white charity” logic. Instead\, sharing skills\, hacking tools\, and m
 aking knowledge openly accessible—disaster relief as a commons. In this ta
 lk\, we'll share how a DIY project from the subculture has evolved into an
  organization that now builds medical infrastructure\, tech solutions\, an
 d training in crisis areas—with bright minds from different disciplines\, 
 open-source hardware\, and a lot of improvisation.\nWe talk about what it 
 means to de-elitize humanitarian work: How can we act in conflicts\, clima
 te disasters\, or collapses without slipping into old power logics? How ca
 n practical solidarity be scaled without becoming an NGO apparatus? And wh
 at can nerds\, makers\, and activists contribute in concrete terms when th
 e world is burning? A reality check with hopefully contagious energy for a
 ction—from the idea to the reality of deployment. No hero stories\, but ma
 ny lessons learned and open construction sites.\nEspecially with regard to
  Gaza\, Ukraine\, Sudan\, and the climate crisis\, we want to show that th
 e ability to act is not a question of profession\, uniform\, or mandate—bu
 t of collective creativity\, technical openness\, and solidarity-based cou
 rage.\n

DESCRIPTION:Aufgrund des Supportendes von Windows 10\, zielt die endof10-Ka
 mpagne darauf ab\, Unterstützungsnetzwerke aufzubauen\, um Menschen beim U
 mstieg auf Linux zu unterstützen. \n\nAber wie können die betroffenen Mens
 chen erreicht werden\, die vielleicht noch nie von Linux gehört haben?\nMi
 t Linux können Computer\, die nicht die Hardware - Voraussetzungen für Win
 dows 11 erfüllen\, noch lange sicher weiter betrieben werden. In einer kur
 zen Einführung von ca. 20 Minuten\, möchte ich meinen Weg beschreiben\, wi
 e ich mich immer mehr in der Endof10-Kampagne engagiert habe\, obwohl ich 
 keine Linux-Expertin bin.\n\nIch möchte meine Erfahrungen mit dem Organisi
 eren von Linux-Veranstaltungen in Berlin mit euch teilen und darüber sprec
 hen\, wie mein Netzwerk immer mehr gewachsen ist.\n\nFür den Umstieg auf L
 inux richte ich mich mit meinen Unterstützungsangeboten hauptsächlich an ä
 ltere\, aufgeschlossene Menschen. Diese leben entweder in meiner Nachbarsc
 haft oder sind in politischen Gruppen aktiv.\nEs gibt auch eine Kooperatio
 n mit dem Technikmuseum in Berlin\, wo wir einmal im Monat ein Linux-Café 
 anbieten.\n\nAnschließend möchte ich euch einladen\, Ideen und Erfahrungen
  darüber auszutauschen\, wie auch ihr Teil dieses globalen Graswurzel Unte
 rstützungsnetzwerks werden könnt (falls ihr nicht schon dabei seid).\nWich
 tig ist dabei lediglich\, dass euch das Thema wichtig ist (z.B wegen Verme
 idung von Elektroschrott oder Unabhängigkeit von Microsoft). Jede Person h
 at etwas\, das sie beitragen kann.\n\n\nFLINTA-Only.  Die Unterstützungsst
 rukturen sind bisher stark männlich geprägt. Über mehr Sichtbarkeit von FL
 INTA-Personen in diesem Bereich würde ich mich freuen.\n

 anbieten. Stricken ist eine tolle Fertigkeit\, die Du Dir am besten "learn

 en sofort einige Grundlagen lernen oder über Projektideen sprechen. Falls 
 Interesse besteht\, können wir über das upcycling alter Pullover(garne) sp
 rechen.\n\nI would like to offer a knitting workshop / gathering for begin
 ners and everyone else interested in knitting a few stitches at 39c3\, and
  sharing their skills with beginners. I think knitting it is a wonderful s
 kill best to be learned by doing and face to face. Beginners could learn s
 ome basics straight away\, or talk about project ideas. If there is anyone
  interested in talking about the re-use / upcycling of old sweaters & swea

DESCRIPTION:\nHygiene Training according to § 43 IfSG (German Infection Pro
 tection Act)\n\nWe are again conducting hygiene training sessions — the "M
 eatball Diploma"\, as it's called in German slang — for everyone involved 
 in food preparation for others.\n\nThe goal is to raise awareness of a hyg
 ienic environment surrounding the preparation and serving of food at 39C3 
 and\, consequently\, to contribute to a higher level of healthiness of us 
 all.\n\n\nIdeally\, this training is preceeded initially by an instruction
  by the relevant public health department (Gesundheitsamt). Even better\, 
 of course\, is if you have already attended "follow-up training"\, for exa
 mple\, at 38C3 or CCCCamp.\n\nIf you have any relevant documents\, please 
 bring them along so we can update\, stamp\, and sign your proof of trainin
 g. :-)\n\nOf course\, we also welcome everyone who is joining us for the f
 irst time without prior training from the public health department and/or 
 without any prior knowledge of food hygiene at all.\n\n\nWe look forward t
 o seeing you! - Be excellent to each other :-)\n\nTeam C3GELB (DECT 4352)\

DESCRIPTION:\nThis workshop is for all who do not know at all or only have 
 a vague idea what an “IP address” is. We’ll learn how the Internet works b
 y making Internet traffic visible. This is a beginner’s workshop. If you t
 oyed with Wireshark before\, you will be bored to hell in this workshop.\n
 \nInvisible to the casual user\, lots of computers communicate and work to
 gether to deliver the kitten videos you’re craving. In this workshop\, we 
 use the tool Wireshark (available for all operating systems) to make this 
 communication visible. In lots of life demos\, we’ll learn that the domain
  names we’re familiar with\, like ccc.de or fridaysforfuture.de\, are a th
 in layer around IP addresses\, which are the real addresses computers use 
 to identify themselves. We’ll uncover which hidden information your browse
 r sends along each request\, and we’ll see how easy it is to intercept tra
 ffic.\n\nThis workshop is for everybody who is interested in knowing how t
 he Internet works\, in which form computers talk to each other. Absolutely
  no prerequisites are required. People who are familiar with network stack
 s will be bored to hell.\n\nNote to the infrastructure team: In the final 
 part of the talk\, we’ll perform a standard ARP spoofing attack to interce
 pt traffic from a volunteer and display their website login password on th
 e projector. Of course we won’t use the congress network for this. I’ll us
 e an hotspot of my own.\n\n**[Transcript](https://chaos.quasicoherent.io/)

 t:**\n\nADHD is becoming increasingly visible in society and research\, wi
 th many individuals receiving late diagnoses\, especially women with ADHD.
  While there has been progress at universities\, including the formation o
 f student groups for neurodiverse individuals\, there remains a lack of vi
 sibility for neurodiverse researchers. This discussion round aims to provi
 de a safe space for everyone - whether they have an ADHD diagnosis or not 
 - to discuss the challenges and benefits of working as a neurodiverse rese
 archer. You are welcome to share your experiences and strategies to manage
  the chaos\, but no one will be forced to.\n\nModeration: Sarah\, who rece
 ived her ADHD diagnosis in 2023\, works as a data scientist since May 2024
 . She will share her experiences and strategies as a woman in science with
  ADHD\, in order to increase the awareness and provide (hopefully) helpful
  insights.\n\nTarget audience:\n- Neurodiverse individuals (with or withou
 t a diagnosis)\n- Researchers collaborating with neurodiverse colleagues\n
 - Anyone interested in learning about the needs and challenges of individu
 als diagnosed with ADHD\n\nOther neurodiverse individuals are also warmly 
 invited to join the discussion and share their knowledge. However\, due to
  Sarah's own diagnosis\, she will primarily address ADHD related topics\, 
 as she can only talk about her own experiences\n

DESCRIPTION:\nFor two years now\, children in the public education system o
 f the russian federation are subjected to an unthinkable scale of militari
 stic indoctrination. Every child takes part in around 70 war-related holid
 ays per year. The more talented ones are involved into propaganda activiti
 es to such degree that they have practically no time to study.\n\nIn this 
 SoS we won't like just to point out that millions of children are being mi
 litarized at an unthinkable scale. We also would like to speculate a bit o
 n how and why it is possible that many of you still probably do not know a
 bout it.\n\n---\n\nTo draw attention to the above-mentioned topic\, there 
 will be also a video installation parallel take place at the monument "Kri
 egsklotz” not so far from the CCCH ( https://www.openstreetmap.org/?mlat=5
 3.559128&mlon=9.989267&zoom=18 ). The installation will be available durin
 g 39C3 every night between 16:00 and 00:00. We recommend taking a look at 
 this installation too.\n

 makes Lego Dots™ exciting is that you are bound to a grid – in this case\,
  8×8 units. The tiles come in different shapes: circles\, squares\, quarte
 r circles\, and many more. Have a look at the gallery to see some examples
 .\n\nWe print using a press from the Open Press Project.\nThe print size i

 ektronische Musik auf einem hybriden Setup\, bestehend aus einem kleinen m
 odularen System und digitalen Komponenten\, die in Pure Data programmiert 
 sind. Der Fokus liegt auf der musikalischen Erforschung roher elektronisch
 er Klänge ohne den Einsatz von Echo\, Hall oder Loopern. Auch wenn es rhyt
 hmische Momente geben mag\, stehen diese nicht im Mittelpunkt\, ebenso wen
 ig wie Harmonie und Melodie – vielmehr sind technische/mathematische Struk
 turen die Ausgangspunkte. Die ästhetische Anziehungskraft entsteht durch d
 ie Akzeptanz des Klangmoments als kognitive Erfahrung und die gemeinsame W
 ahrnehmung eines Spannungsbogens durch Publikum und Performer*in.\nImprovi
 sed electronic music on a hybrid setup consisting of a small modular syste
 m and digital components programmed in Pure Data. The focus is on the musi
 cal exploration of raw electronic sounds without the use of echoes\, rever
 b\, or loopers. Even though there may be rhythmic moments\, these are not 
 the focus\, nor are harmony and melody—rather\, technical/mathematical str
 uctures are the starting points. The aesthetic appeal arises from the acce
 ptance of the sound moment as a cognitive experience and the shared percep
 tion of a tension arc by the audience and performer.\n\n#### Artist Bio:\n
 \ni am an electronic/experimental musician\, composer\, improviser\, progr
 ammer based in leipzig/germany.\n\nafter more than 3 decades as a professi
 onal musician and instrumental teacher in various styles and on various tr
 aditional instruments\, i have become a little bored and saturated with it
 . in addition\, i have felt the desire to devote my life to other tasks su
 ch as left wing political\, activist work and exploring the social space. 
 therefore i have decided to stop making traditional music and to focus mus
 ically on improvisation and electronic sound generation.\n\nthis allows me
  to combine some strong interests - for example\, exploring sounds\, compu
 ter programming\, electronic tinkering - and use them for my artistic work
 . i play live with a small modular system as well as with self-developed d
 igital\, computer-based instruments and controllers. in addition to ensemb
 le \nimprovisation\, i am increasingly interested in solo performances. th
 rough my long time as a wind instrumentalist i have become accustomed to a
 lways using my breath for articulation and dynamic control. \nthat's why i
  usually use a breath controller for my electronic performances.\nin this 
 concert i expect to use an eurorack-modular in combination with pure data 
 & supercollider\n

DESCRIPTION:\nAstrology is usually associated with horoscopes\, prediction\
 , or belief systems. In this self-organised session\, we’ll test a differe
 nt idea: using astrology as a symbolic language to reflect on daily routin
 es\, decision-making\, and energy management — without fate\, mysticism\, 
 or “the stars made me do it”.\n\nThe session is interactive and experiment
 al. We’ll look at how astrological concepts can function similarly to tool
 s people already use: retrospectives\, calendars\, personality models\, or
  context-setting frameworks.\n\nThis is not about accuracy\, belief\, or c
 onvincing anyone. It is about usability:\n\nDoes this framing help reflect
 ion?\n\nWhere does it break down?\n\nWhen does it become annoying or meani
 ngless?\n\nNo astrology background required. Critical perspectives are exp
 licitly invited.\n\n- **Presentation (slides shared):**  \n  https://docs.

DESCRIPTION:\nCitizen science can mean many things: DIY measurements\, comm
 unity research\, data activism\, social experiments\, artistic inquiry\, o
 r collective knowledge work. At CCC\, many such projects exist — often wit
 hout ever using the label “citizen science”.\nThis session follows a “show
  your pet” format. Participants are invited to bring and briefly present t
 heir own projects\, tools\, experiments\, or unfinished ideas and share:\n
 what the project does\n\n\nwho participates\n\n\nhow (or if) it serves a c
 ommunity\n\n\nwhether calling it “citizen science” helps or gets in the wa
 y\n\n\nProjects do not need to be finished\, funded\, successful\, or form
 ally recognised. Critical\, messy\, and experimental work is explicitly we
 lcome.\nAlongside peer exchange\, the session creates space to explore if 
 and how collaboration with the wider citizen science community — including
  ECSA — could be useful:\nWhat kinds of support would actually help these 
 projects?\n\n\nWhere does institutional collaboration feel helpful — or ha
 rmful?\n\n\nWhat would make collaboration worth the effort?\n\n\nThe goal 
 is not recruitment or alignment\, but to understand what collaboration sho
 uld look like from the project side\, if at all.\n\nWebsite: https://www.e

DESCRIPTION:With Signal\, Whatsapp\, and other centralized messengers sudde
 nly running their servers in an authoritarian territory\, we need a decent
 ralized alternative. Delta Chat apps work with most e-mail servers but cha
 tmail servers are more secure\, faster and easy to setup\, and have become
  the primary choice for new users. Learn how to host chatmail\, and help c
 reating the resilient chatmail server network for a shattered world!\nYou 
 don't need expensive hardware to run a chatmail server - a cheap VPS or ra
 spberry pi can support hundreds of users. All storage is temporary\, as De
 lta Chat stores messages only on end devices. This makes chatmail tremendo
 usly easy to get started with - bring your child and learn together.\n\nTo
  setup a chatmail server\, you need:\n- SSH root access to a server\, with
  a public IP address\, and a domain (we will bring some for the workshop)\
 n- basic command line knowledge\n\nSo come as you are\, and join this chat

DESCRIPTION:\n_Introduction to Embedded Rust on Microcontrollers and the [H
 akkaa workshop task](https://events.ccc.de/congress/2025/hub/en/project/de
 tail/assembly/hakkaa-board-smd-soldering-embedded-rust-for-begin/). This i
 ntroduction is mostly aimed at participants with some experience in Rust._
 \n\nFor everyone who has already taken their first steps with Rust and can
 't wait to get knee-deep into using Rust on a Microcontroller. It aims to 
 show you the little differences of this environment\, presenting the works
 hop challenge and pointing you in the right direction for getting started.
 \n\nFor absolute beginners we recommend to attend [Rust programming langua
 ge: An absolute beginner workshop with intro presentation](https://events.
 ccc.de/congress/2025/hub/de/event/detail/rust-programming-language-an-abso
 lute-beginner-wor) first and then our [second round of this introduction o
 n day three](https://events.ccc.de/congress/2025/hub/de/event/detail/einfu
 hrung-embedded-rust-fur-workshop-hakkaa-_mlyg).\n\nThis session starts wit
 h a presentation of about 30 minutes in English and a round of questions f
 or all. After that\, our team supports you with your first self-paced step
 s.\n\nThe initial part of the presentation covers using Rust on a microcon
 troller in general. The second part focuses on working with the Hakkaa boa
 rd.\n\nIf you've got a question after this session\, you can find us at th
 e Hakkaatachi assembly or in [our Matrix chat](https://matrix.to/#/#hakkaa
 tachi-39c3:matrix.org).\n\nWe recommend:\n\n* Having a soldered and tested
  [Hakkaa-Board](https://github.com/hakkaatachi/hakkaa-hardware) (whose kit
  you can get at the Hakkaatachi assembly)\n* Your laptop set up with the [
 development tooling](https://github.com/hakkaatachi/hakkaa-firmware?tab=re
 adme-ov-file#setup) so that you can spend more time on programming than on
  installing\n* Your laptop fully charged\n\nReferences:\n\n* [Presentation

  you do it?\nDo you have any hacks to prevent you from shooting yourself i

  conversation started\, I will give a short talk about my journey through 
 the testing jungle.\nAnd then let's have an open discussion where you can 
 talk about your testing approach. It would be awesome if you could show us
  a test you wrote.\n\nEveryone is welcome\, especially if you're just curi

DESCRIPTION:\nYou probably have heard of "Venture Capital" - the mysterious
  infinite source of money that powers the startups of Sillicon Valley (and
  beyond)\, that powers the "AI revolution" and "crypto revolution." You ev
 en might have heard names like YCombinator and a16z\, or terms like "Unico
 rn"\, "PMF" and "TAM".\n\nBut where does that money come from? How can you
  get it? And why do people continue to give money to startups\, despite 90
 % of them returning 0 money?\n\nEven among IT nerds\, VC is often seen as 
 something vague and mysterious - despite it shaping the world of technolog
 y since the early 2000s. Some people get money\, some don't - with little 
 rhyme or reason.\n\nThis is a small talk of someone who actively participa
 ted in the VC ecosystem. The primary goal isn't to bash or praise that ind
 ustry (though it deserves a lot of bashing)\, but to shine a light on how 
 it works under the hood.\n\nNote: this is an adapted version of a short le
 cture I gave at the Mega-Knowledgecamp (Hacksaar 2025)\n

DESCRIPTION:\nWe all struggle with lots of passwords\, often forgotten\, re
 used or leaked. Passkeys promise to free us from both the hassle and the b
 reaches. But will they solve authentication\, or are they failed by design
 ? A deep‑dive into convenience\, control\, and everything between.\n\nPass
 keys are designed to replace passwords. All you need is your phone or hard
 ware token\, meaning you have to remember only one password at most. But i
 sn't that the promise of password managers? Although they fulfil a similar
  role\, password managers usually use classic passwords\, making them seem
  like an interim solution on the way to more secure authentication. Wouldn
 't it be great to get rid of passwords once and for all and switch to pass
 keys?\n\nWhile passkeys promise a passwordless future\, the reality is far
  more complex. User reluctance\, questionable usability and corporate inte
 rests are making the case for passkeys increasingly difficult. So let's de
 lve into whether passkeys do make sense from the perspective of both profe
 ssional and regular users.\n\nThis talk is not a technical deep dive into 
 passkeys\, but rather addresses the issues of IT management & IAM and whet
 her secure "passwordless" auth can work in the real world. The aim is not 
 to give a bureaucratic or opinionated talk\, but to open a discussion abou
 t enshittification and whether auth (doesn't) work(s) for both regular and
  pro users.\n

DESCRIPTION:Chaos Communication Congress (C3) is a big annual event for peo
 ple who love technology\, cybersecurity\, free culture\, and creativity. S
 ince 1984\, it has been held in Germany\, first mostly in German\, then in
  English to connect people worldwide.\n\nToday\, thanks to International S
 ign (IS)\, everyone deaf or hearing can fully join. IS makes communication
  open\, equal\, and accessible\, helping people overcome language barriers
  and work together.\n\nThere are over 300 sign languages in the world\, so
 me more than 5\,000 years old. IS has been used for several decades by the
  World Federation of the Deaf (WFD) and the Deaflympics Games (ICSD). Thes
 e organizations used to have a hierarchy\, but today IS allows a holarchy\
 , where everyone has a place and communication is shared equally.\n\nA big
  question is: why choose English instead of International Sign? English he
 lps hearing people communicate worldwide. But IS allows deaf and hearing p
 eople to connect more equally\, opening space for sharing and understandin
 g deaf cultures.\nIn a world dominated by surveillance and digital control
 \, oral languages are constantly monitored\, but sign languages remain lar
 gely invisible to automated systems. This session explores the intersectio
 n of hacker culture\, Deaf culture\, and communication\, questioning domin
 ant linguistic norms and hearing privilege. Participants will experiment w
 ith sign language as a tool for privacy\, creativity\, and subversion\, ex
 plore collaborative multilingual communication\, and reflect on the politi
 cs of visibility and language power. Open to all signers\, non-signers\, a
 nd curious minds ready to hack communication.\n\nKey themes:\n\nSurveillan
 ce and privacy\n\nHacking communication\n\nSign language as a free / untra
 ceable space\n\nPolitics of visibility and language power\n\nExperimentati
 on\, creativity\, and reinvention of norms\n

DESCRIPTION:Despite years of information security innovation\, user safety 
 continues to decay and digital systems remain vulnerable. The reason: most
  attacks exploit a flawed first principle of digital identity\, built on e
 ntrenched assumptions about presentation\, authentication\, enforcement\, 
 and trust. As societies digitize and digital identity becomes the endpoint
  for all contact between citizens\, institutions\, and infrastructure\, th
 is collective failure to imagine new designs will shatter how we cultivate
  social trust. How else can this state of affairs\, where no single attrib
 ute of a person can escape the reach of bad actors\, be brought to an end?
 \n\nDrawing on unprecedented access to individuals across the digital iden
 tity landscape and organisations developing the next wave of identity solu
 tions\, The Digital Identity Event Horizon presents New Design Congress' a
 nalysis of the core emerging socio-technical threats inherent in all digit
 al identity systems\, and lays the case for why proposed solutions will no
 t address these threats without radical rethinking.\nWhat happens when thr
 eat modelling becomes reality? This is the story of a research team caught
  in the mask-off moment for digital identity\, documenting the technology'
 s inherent dangers at the exact moment its weaponised design revealed itse
 lf.\n\nOver four years\, New Design Congress conducted eight case studies 
 across implementations ranging from national biometric schemes to Web3 zer
 o-knowledge proofs. More than 45 participants\, including law enforcement 
 officers\, military personnel\, information security researchers\, CEOs\, 
 and activists\, spoke candidly about digital identity's failure modes. The
  resulting 600+ citations documented a fundamental problem: the Cartesian 
 vulnerability. "I authenticate\, therefore I am" - when proving identity b
 ecomes inseparable from possessing identity\, social-engineering attacks b
 ecome inevitable. When identity infrastructure becomes a single point of f
 ailure\, it tears at the fabric of society itself.\n\nSince 2021\, New Des
 ign Congress has applied adversarial security research methodology to the 
 question of flawed digital identity: its definitions\, implementations\, a
 nd implications. From FaceID to BankID\, from Facebook to the fediverse\, 
 from Worldcoin to the world's passports\, this is an exhaustive study of t
 he opportunities and risks that emerge from how we represent entities in t
 he information age. At the centre is a core hypothesis: today's digital id
 entities are inherently vulnerable to attack\, and this leads to brittle d
 igital societies.\n\nThis talk presents the threats and findings for the f
 irst time. It is for anyone who still believes today's technologies can sa
 fely represent humans. The report it is based on\, The Digital Identity Ev
 ent Horizon\, is a landmark adversarial study that names the concrete harm
 s of digital identity directly\, establishes a working definition\, introd
 uces a threat modeling framework for evaluating any scheme\, and presents 
 ten key findings and fourteen recommendations\, with many immediately  imp
 lementable across policy\, design\, and governance.\n\nThe report will be 
 soft-launched at https://newdesigncongress.org/en/report/2026/the-digital-
 identity-event-horizon.\n

DESCRIPTION:Let's snack and chat! We want to invite you to collectively ref
 lect the relationship between activism and academic research with us. \n\n
 As hegemonic and intersectionally discriminatory institutions\, universiti
 es re-produce global structures of domination and oppression. And regularl
 y\, insights from activism inspire academia rather than vice versa. Still\
 , research is a relevant module to understand and meaningfully participate
  in the world around us. But the line between research and activism become
 s blurred anyway. Activists are researchers and researchers are activists\
 , participating in both worlds\, oftentimes trying to bring them together.
  Here\, long-term research projects that illuminate specific processes in-
 depth tend to collide with the rather short-term struggles of activism tha
 t need immediate responses to current issues. Therefore\, we want to elabo
 rate with you: (How) Can academic research and activism in SAR interact in
  solidarity?\n\nIn our own roles as researchers and activists\, we appreci
 ate both forms of working and knowledge-producing and are well aware of ch
 allenges and difficulties. Together with you\, we want to discuss all thes
 e challenges and difficulties - but also work out and underline potentials
 ! \n\nWe organized a workshop like this already at the SAR-Camp in Septemb
 er in Biesenthal. We invite people to newly join in and to follow-up. If y
 ou like to\, bring some snacks or your breakfast\, lunch\, dinner\, ... Th
 e format is meant to be low-key and comfortable!\n

DESCRIPTION:Fünf Stromerzeuger dominieren den deutschen Strommarkt. Zusätzl
 ich sitzt mit Katherina Reiche eine Person an der Spitze des Wirschafts- u
 nd Energieministeriums\, die vier Jahre lang eine Führungsposition innerha
 lb des Energiekonzerns E.ON innehatte. Zwar gibt es Energiegenossenschafte
 n und Balkonkraftwerkbesitzer*innen\, die versuchen\, sich von diesen Mach
 tstrukturen ein Stück weit unabhängig zu machen\, aber sie produzieren nur
  einen Bruchteil der Energie\, die tagtäglich nachgefragt wird. Die Kampag
 ne RWE und co enteignen setzt sich deswegen für einen Strommarkt ein\, der
  nicht länger von Profitinteressen getrieben wird\, und arbeitet an einem 
 Plan\, wie dies durch Vergesellschaftung umgesetzt werden kann.\nMit der V
 ergesellschaftung des Energiesektors in NRW wollen wir die Demokratisierun
 g der (Energie)Wirtschaft und eine ernsthafte sozial-ökologische Energiewe
 nde erreichen. Auf juristischer Ebene beinhaltet das die Umwandlung von gr
 oßen privatwirtschaftlich organisierten Unternehmen in Anstalten des öffen
 tlichen Rechts\, auf gesellschaftlicher Ebene leitet es einen Paradigmenwe
 chsel ein: von Oligopolstruktur\, Intransparenz und riesigen Profitmargen 
 hin zu solidarischen Preismodellen\, einem Energiemarkt\, der auf Erneuerb
 are ausgelegt ist und vor allem hin zu einem direkt demokratischen Entsche
 idungsprozess\, an dem alle Betroffenen beteiligt sind - Angestellte\, Str
 ombeziehende\, von Klimawandel und Energieressourcenabbau Betroffene...\n\
 nWie könnten Entscheidungsprozesse in einem vergesellschafteten Betrieb au
 ssehen? Erfüllt unser aktuelles Strommarktdesign die Voraussetzungen dafür
 ? Wie funktioniert unser Energiesystem und warum scheitern privatwirtschaf
 tliche Unternehmen an der Umsetzung der Energiewende? Und wo könnten gesel
 lschaftliche Hebel liegen\, um eine Vergesellschaftung auch tatsächlich um
 zusetzen?\n\nIm Workshop wollen wir unsere Überlegungen dazu vorstellen un
 d sind gleichzeitig auch gespannt auf eure Gedanken zum Thema - denn auch 
 Technik braucht Strom\, also lasst uns überlegen\, wie Produktion und Vert
 eilung demokratischer organisiert werden können!\n

DESCRIPTION:An interactive workshop for those who regularly deal with resea
 rch code. We'll discuss lessons learned\, reflect on our work and use our 
 combined experiences to develop a list of best practices for writing\, doc
 umenting & publishing software for research projects.\nAre you a researche
 r who writes code? An intimidated grad student who's scrambling to learn R
  or Python? Or maybe a software developer who works with researchers? Whet
 her you're just starting out or have been doing this for decades\, this wo
 rkshop is for you. Let's come together to share our experiences – the horr
 or stories\, a-ha moments and imposter-syndrome-induced doubts – with writ
 ing\, documenting\, publishing\, and reusing research code.\n\nModern rese
 arch often depends on patchworks of custom code\, organically grown over t
 he lifespan of a project. Scripts written on the fly\, evolving as questio
 ns change and deadlines loom. Many\, if not most\, of us never received an
 y formal training to write code that others (or even just our future self)
  could actually understand and use. Instead\, we learn by trial and error 
 – and\, most importantly\, from each other.\n\nTake this workshop as an op
 portunity to share what you know\, help out others and learn a few new tri
 cks. Together\, we'll:\n- Define what "computational reproducibility" mean
 s to us\n- Discuss our experiences producing and reusing research code\n- 
 Reflect on how the daily work of researchers has changed and what constrai
 nts we face\n- Share what strategies and tools have worked for us in the p
 ast\n\nThe goal is to develop a set of community guidelines or best practi
 ces for working with research code that are applicable and accessible acro
 ss disciplines and backgrounds.\n\n---\n\nNote:\n- This workshop aims to c
 enter perspectives from marginalized folks whose voices frequently go unhe
 ard in academia. If that includes you\, your participation is especially v
 alued.\n- This session can also be held in German if all participants spea
 k German.\n

 ss die Bar das wichtigste Element eines Clubs ist. Er ist ausserdem seit s
 einem 22. Lebensjahr ein erfolgreicher Leser und kann seit kurzem 6 der 8

 Aber Autogramme geben muss er ja eh nicht.\n\nWie im Hitchhikers Guide emp

 ent is dedicated to cider\, cidre\, sidra or how ever you would like to ca
 ll beverage prepared by fermentation of apple juice. This event is run by 
 František [[User:Algoldor|Algoldor]] Apfelbeck and is one of the activitie
 s of the [https://cidreriejara.com/wiki/Main_Page Cidrerie Jara/Kvasírna J
 ara] project which is a commercial one.\n\n'''Aims&Selection'''\nThe aim o
 f this event is to educate people about cider in a nice and socially frien
 dly environment. It is guided tasting with short foreword and then after o
 pening first bottle just continuing with other ones when talking on the su
 bject of cider and it's making. We provide a high quality selection of cid
 ers focusing on "typical" products\, plus we add some really special sampl
 es depending what we have available. At the core of the tasting are French
  ciders\, especially from Normandie region and partly Bretagne. From the g
 eographical point of view we generally have at least one sample from North
  of Spain\, Andalusia or Basque. There is cider from England\, because of 
 strong connections to Czech Republic we try to have there one from there a
 nd generally we include at least one [https://en.wikipedia.org/wiki/Apfelw
 ein German Apfelweine]\, the rest depends what interesting samples we get.
  From the point of view of style of production we are selecting mostly the
  more "complex" "natural ciders" made from cider apples\, if possible with
 out any additives\, unfiltered and secondary fermented in the bottle (pris
 e de mousse naturelle). That would be the highest end. It is however hard 
 to make whole tasting in quality like this so we also get small scale bio/
 organic production. These are good quality ciders which may be for example
  filtered\, some enzymes added\, sulfur etc. We generally include one clas
 sic big scale commercial cider for comparison. To increase a bit of spectr
 um of what can be done we like to have some flavoured ciders\, like raspbe
 rry cider\, honey cider etc. We do like to include one or two [https://fr.
 wikipedia.org/wiki/Poir%C3%A9 poirés (perry)] into the selection. It happe
 ns quite often that it is the first poiré which people had in their life a
 nd if you are not in the region or you don't have next to you really good 
 alcohol shop it is really hard to get a high quality one. To finish the ta
 sting we have at least one or two cider related products like pommeau\, ca
 lvados or vinegar.\n\n'''Style'''\nThis tasting workshop is based on "dona
 tion at your will no one turned away for lack of funds" creed. However ple
 ase keep in mind that samples and ingredients for this event will be aroun
 d 150-200 eu and ending up in a decent plus would help covering costs rela
 ted to my\, [[User:Algoldor|Algoldor]]\, presence at this event. This is a
  guided tasting. During the presentation we talk about the cider in genera
 l as mentioned above. At the beginning of the tasting it is explained how 
 to taste and evaluate the product properly. We talk about the proper shape
  of glasses\, temperature of serving\, preparing the pallet and so on. We 
 discuss also the colour\, difference of astringency\, bitterness and acidi
 ty\, levels of sparkliness and more. Concerning the products we start with
  the extra-bruts and we go in the direction of increasing sweetness toward
 s bruts\, demi-secs and douce. We try to make a list of ciders which we ta
 ste at the event with the contact details so you can get them if you like.
  At the end of the event we offer [https://cidreriejara.com/wiki/Main_Page
  Cidrerie Jara's ciders] and other products for sale for suggested donatio
 n in a legal manner so you can get a receipt\, the taxes are paid. However
  we are trying to avoid "commercialization" of the CCC events\, so it is r
 ather about getting a bottle or two and buying more later on through deliv
 ery\, inviting us to do cider tasting at your place or getting stock of bo
 ttles stocked for your local hackerspace. Part of the funds which we got f
 rom this event goes to fhb and the larger part to [[User:Algoldor|Algoldor
 ]] covering costs for participation and also using it for fermentation pro
 jects and day to day life expenses.\n\n\n'''Most Frequent Candidates'''\nH
 ere you can find some basic tips for nice ciders which I either liked or a
 re introduced at the tastings. Not all of them are always "on" but several
  of them are core members. It changes of course with time to reflect the s
 easonality and the specificity of the product.\n\n'''List of Ciders'''\n{|

DESCRIPTION:The traditional cheese tasting! - Session 1\n[To secure spot on
  the Session I. (Day 1\, SAT 20h30) please sign in here](https://dud-poll.
 inf.tu-dresden.de/cheese1_39c3/)\n\n[To secure spot on the Session 2. (Day
  3\, MON 20h30) please sign in here.](https://dud-poll.inf.tu-dresden.de/c
 heese2_39c3/)\n\nEach cheese tasting session is open to 25 people max\, pl
 ease do sign in advance\, you can just show up before the event but we are
  very likely going to be full for this one (like three times overbooked). 
 If you can bring cheese which you made by yourself that would be great! Of
  course some specific local or extraordinary cheese/s or other related con
 diments like sun dried tomatoes\, good quality olives\, mustards\, wine al
 l would be appreciated. If you are bringing cheese please do label it well
  with at least it's name and type of milk used\, your nick or name/contact
  would come handy too. The best would be of course to add short descriptio
 n to our wiki (please check the sample). Still please sign in in advance! 
 FHB will be getting some high quality cheeses to offer basic selection wit
 h other samples surrounding it plus some basic condiments. Note that due t
 o the interest in previous years we are going to run two sessions\, each o
 ne lasting for about two hours or bit over.\n\nThis event is based on dona
 tion at your will no one turned away for lack of funds.\n\nSo lets meet al
 l together again enjoying these lovely creations! Here you can find cheese
 s which are going to be present\, please do add your ones and keep in mind
  that good half of the cheeses will be not listed here\, they will just ap
 pear and they are worth of your attention!\n\n[A full overview of cheeses 
 you can get here](https://foodhackingbase.org/wiki/FHB@39C3/Cheese_Rendezv

DESCRIPTION:\nJujutsu (jj) is a new version control system that uses Git as
  its backend. Since trying it last year\, it has completely replaced Git f
 or me. It manages to be less complex than Git\, while giving you more cont
 rol. I think you'll like it too!\n\nLately\, when people ask me complex Gi
 t questions\, my answer is often: "First\, install jj…" And that's only ha
 lf a joke. :P\n\n---\n\nA few things I like about Jujutsu: There's no inde
 x\, but instead you get a subcommand for splitting changes. Commits have s
 table IDs that stay the same even after rewriting. Anonymous branches! Con
 flicts are first-class objects and don’t have to be resolved immediately d
 uring a rebase. Rewriting history is very easy.\n\nAnd because it's Git-co
 mpatible\, you can use Jujutsu right away in existing projects without any
 one else noticing. :3\n\nI'm planning to do this session in two parts: Fir
 st\, an introductory talk about jj. After that\, a "workshop" part where y
 ou can install Jujutsu and try it for yourself!\n

 ur starke Meinungen zu Programmiersprachendesign haben :-)\, sondern auch 
 mit zivilem Ungehorsam versuchen\, einen Beitrag für Klimagerechtigkeit zu

DESCRIPTION:\nÄhnlich wie in den letzten Jahren wollen wir uns auch dieses 
 Jahr wieder treffen und uns rund um das Thema Verwaltungsdigitalisierung a
 ustauschen und vernetzen.\n\nWas ist der Faxgeräteclub und warum machen wi
 r das?\n\nWenn wir über Behörden-IT sprechen\, dann sprechen wir oft über 
 einen zwingend notwendigen Wissensaufbau und die Internalisierung von IT-K
 ompetenz in der öffentlichen Verwaltung. Aber wer sich dann tatsächlich fü
 r einen Job in der Verwaltung entscheidet oder aus der Zivilgesellschaft h
 eraus positiv auf die Verwaltung einwirken will\, die:der braucht viel Übe
 rzeugungstalent und oft auch Durchhaltevermögen. Aber wir können auch viel
  Positives bewirken.\n\nWoran scheitert es in der Praxis\, wo liegen die s
 trukturellen Probleme und welche Impulse braucht es jetzt aus der Politik?
 \n\nWir sprechen im Faxgeräteclub über unsere Erfahrungen im Alltag in und
  mit Behörden\, darüber\, was in der Verwaltung alles noch falsch läuft un
 d wie wir gemeinsam etwas daran ändern können. Kommt vorbei uns lasst uns 
 gemeinsam in lockerer Runde ein wenig diskutieren und Pläne schmieden! Wil
 lkommen sind alle\, die sich für die IT der öffentlichen Verwaltung intere
 ssieren und/oder gerne mit uns ihre Ideen oder Fragen teilen möchten.\n

 narchy\, open relationships\, solo-poly and so on are on the rise.\nBut un
 derstanding\, what these new approaches to relationships are all about som
 etimes seems a little difficult because of all the lingo we use to make ou

 of strange terms like polycule\, compersion or metamour\, easily misunders
 tood ideas like garden party enm vs. kitchen table enm\, or acronyms like 
 NRE. Armed with these (new?) concepts we'll also have a little Q&A where w
 e'll try to give some insights into the realities of ENM life.\n

DESCRIPTION:\nLike last year we jam (playing spontaneous/improvised music f
 or ourselves) together in small groups. In order to avoid a high noise lev
 el in the room we are going to use Headphones. We welcome every kind of In
 strument from your laptop with a midi-controller\, your E-Guitar\, a Micro
 phone to your modular synthesizer. If you want to participate please read 
 the following carefully.\n\nPlease bring the following with you if you pla
 n to participate: (if you don't bring the stuff you may be able to borrow 
 it)\n- Headphones\n- Extension Chord/Power Strip if your stuff needs power
 \n- Cable to send your tones to the other people. Small audio jack is the 
 prefered method. Adapters are nice.\n\nIf you can\, it is nice to bring In
 struments for other people so people can participate without knowing about
  the jam before congress. It is probably a good Idea to write your name/a 
 unique identifier on your stuff to avoid confusion.\n\nI have designed a P
 CB that lets 5 People plug in their instruments and headphones via small a
 udio jack. Only the Headphone volume can be adjusted on the board. Unfortu
 nately the board is still in the mail and I don't know if it works at all.
  For this reason it would be nice if you could bring Equipment to route pe
 oples audio signals to Headphones. Especially Mixers Multi-Headphone-Ampli
 fiers and Cables to connect everything together would be appreciated.\n\nM

DESCRIPTION:\nWe live in times of intense conflicts and their violent escal
 ation. One of the central theses of Jalka's work is that a viable democrac
 y and a conscious culture of constructive conflict resolution go hand in h
 and.\n\nCultivating this ability requires a conscious decision to engage w
 ith individual\, collective and societal patterns of dispute behaviour and
  conflict management. Starting with oneself\, as well as in our interactio
 ns with others\, in public discourse and in our behaviour towards others. 
 With a willingness to change something in order to reduce\, and in the bes
 t case even prevent\, the suffering and violence that can potentially aris
 e from conflicts. And to learn from this for the future.\n\nWhat exactly w
 ill this SOS session be about?\n\nWe will engage in a number of exercises 
 and discussion rounds based on the following questions:\n\nHow do you deal
  with conflicts? How do others deal with conflicts? How do you experience 
 conflicts? What exactly are conflicts? What dynamics promote conflicts? Wh
 at patterns are there in place? How can we deal with conflicts constructiv
 ely? How do conflicts caused by individual\, interpersonal and structural 
 factors differ? And: How can conflict management be designed to be sensiti
 ve to discrimination?\n\nI will share with you my experiences from my work
  as a mediator and from past workshops I have held on this topic. In addit
 ion to exercises\, I will also bring along some literature for further rea
 ding.\n\nPlease feel free to bring your own questions and insights to the 
 session so that we can all learn from and with each other. I look forward 
 to seeing you.\n\nin parts translated with DeepL.com (free version)\n

DESCRIPTION:The Uncontrolled Manifold works with electronics and machines t
 hat possess autonomy and obstinacy. These machines are brought into intera
 ction with each other\, creating danceable polyrhythms and\, at the same t
 ime\, a fascinating shadow play\, because the machines are mounted on an o
 verhead projector and their interaction is projected. Analog oscillators g
 enerate self-organizing coordination dynamics and organic patterns\, while
  motors strike rubber strings producing deep\, resonant bass sounds remini
 scent of shamanic drumming. Supported by the visuals spectators may feel l
 ike being dragged into the vortex of a living clock\, compelled to join th
 e performance through movement and dance.\n

 meets Chaiselongue.\nStell dir vor: gedämpftes Licht\, ehrfürchtige Congre
 ss-Stille\, vielleicht ein Glas Rotwein. Eine Mateflasche fällt um und nie
 mand applaudiert. Sei bereit für eine Stunde voller lyrischer Hochkultur. 
 Doch statt Rilke und Schiller erklingen die unsterblichen Verse der Kassie
 rer – vorgetragen mit jener getragenen Feierlichkeit\, die man eigentlich 
 für Sturm und Drang reserviert.\n\nWas passiert\, wenn man "Das schlimmste
  ist\, wenn das Bier alle ist" behandelt wie Heines "Loreley"? Wenn Stroph
 en über Zerstörung und Rebellion plötzlich die gleiche ehrfurchtsvolle Int
 erpretation erfahren wie Weimarer Klassik? Wir präsentieren: Die große Ver
 söhnung zwischen Sicherheitsnadel und Smoking\, zwischen Moshpit und Musen
 saal.\n\nEntdecke die verborgene Poesie im Pogo\, die Metaphorik im Mittel
 finger\, und die überraschende Erkenntnis\, dass "Keine Macht für Niemand"
  eigentlich erstaunlich gut klingt\, wenn man es ausspricht wie ein frisch
  ausgegrabenes Goethe-Fragment.\nHochkultur ist auch nur Punk mit besseren

 soldering workshop for creating motorcontrollers that bring motors to tap 
 rhythmically with each other. Each participant builds her own board to dri
 ve two motors that will then tap in polyrhythms. The electronic circuits i
 n this workshop derive from minimal and low-cost bio-inspired robots. Osci
 llators are used to drive motors that produce sound\, but they can also be
  connected to synthesizers. Each circuit board is designed to be wired up 
 with the boards from the other participants in order to explore together t
 he magic of emergent polyrhythm by wiring their individual circuits to for
 m a huge network.\nBig fun and deep dive into analog circuits and their em
 ergent properties.\n\n\nLink: [https://christian.faubel.derstrudel.org](ht

 t sein - und umgekehrt?\nDigital Humanities: Forschung zu Literatur\, Gesc
 hichte\, Sprache\, Kunst\, Musik in digitaler Form - von Rechercheprozesse
 n über Analysemethoden bis hin zu Publikationsformen. Als Brückendisziplin
  zwischen IT und geisteswissenschaftlichen Fächern operieren die "DH" aber
  nicht nur anwendungsbezogen\, sondern auch transformativ: Sie evaluieren 
 kritisch im Diskurs\, welche Aspekte der fortlaufenden Digitalisierung für
  die wissenschaftliche Praxis förderlich genutzt werden können.\n\nDamit s
 orgen sie aber auch stets für Aufregung\, wenn es darum geht\, etablierte 
 wissenschaftliche Prozesse zu stören: Etwa\, wenn es um Open Source\, Open
  Science\, Open Data geht sowie um FAIR- und CARE-Prinzipien oder um nicht
 proprietäre Standards. Wir begleiten als Digital Humanists somit nicht nur
  die Digitalisierung von Kulturdokumenten und Wissenschaft(sbürokratie)\, 
 sondern auch von Arbeitsprozessen mit dem Ziel\, in diesem Zuge auch eine 
 freiere\, fairere\, nachhaltigere\, zugänglichere\, offenere und digitalso
 uveränere Wissenschaftspraxis zu etablieren.\n\nWir schließen an die Meetu
 ps der letzten beiden Jahre an und treffen uns wieder zu einem lockeren Ke

DESCRIPTION:\nWettbewerb für Junghackerinnen von 5 Jahren bis 1000\n\nSpaß 
 am Gerät: Mehrere Teams bauen gleichzeitig mit Nudeln um die Wette. Dabei 
 geht es um kreativen Umgang mit Technik und die Erfahrung\, dass man Dinge
  auch jenseits der eigentlichen Verwendungszwecke gut gebrauchen kann. Jun
 ghacker bzw. solche die es werden wollen\, können alleine oder als Team ko
 mmen. Es kann jeder mitmachen\, der weiß\, was eine Nudel ist.\n\nPS: Es w
 erden keine Lebensmittel verschwendet.\n\nPPS: Erwachsene dürfen auch mitm
 achen\, wenn sie den Junghacker keinen Platz wegnehmen. Sie werden aber wa
 hrscheinlich gegen den Nachwuchs verlieren :-D\n

  Vielfalt eines Betriebssystems. Was ist (F)OSS? Wie sieht so ein Linux au

  Linux für Schule und Freizeit zeigen\, die Vorteile von freier OpenSource
  Software erklären\, die Vielfalt der verfügbaren Programme und Tools sowi

  kann man damit Tolles machen? Und wie man mit etwas Kommandozeilen-Magie 
 Andere beeindrucken kann. Von den absoluten Basics bis zu komplexen Einzei
 lern -- natürlich wieder zum selbst erleben und mitmachen!\n\nZielgruppe\n
 \nDieser komplette Workshop ist für absolute Neulinge (Computer überhaupt 
 und/oder Linux). Aber auch\, wer schon Windows einsetzt und mal über den T
 ellerrand schauen will\, vielleicht sogar schon einmal über einen Wechsel 
 nachgedacht hat\, sich aber (noch) nicht traut\, ist herzlich willkommen!\

DESCRIPTION:\nWhen people say Mastodon\, they often mean Fediverse—on the o
 ne hand because Mastodon represents a mainstream within the Fediverse\, bu
 t on the other hand because even microblogging usage patterns can vary gre
 atly and even within Mastodon there is no uniform usage pattern\, which ca
 n make Mastodon seem confusing as a term. Automated posting of RSS feeds\,
  personal exchanges with a closed community\, global networking with peers
  from all over the world\, or individual card index boxes—we categorize di
 fferent ways of using the platform and draw inspiration from unusual appro
 aches to uncover the relevance and potential of Fediverse.\n

DESCRIPTION:Swahili\, lexikographische Daten in Wikidata und Wikifunctions.
  Ein Team so stark wie Timon und Pumbaa.\nAngenommen du reist nach Nairobi
  zu einer Wikimedia-Konferenz\, lernst gerade so Touri-Phrasen wie "Hujamb
 o" und "Asante"\, und plötzlich beginnst du dich für die Datenstruktur der
  Sprache zu interessieren. Das ist mir dieses Jahr passiert. Swahili ist e
 ine faszinierende Sprache\, zu der ich ein bisschen was erzählen werde. Es
  geht u.a. um Nominalklassen und Verbtabellen und wie sie in einen Pandas 
 DataFrame passen.\n\nLeider gibt es ein Problem: Wikidata enthält kaum Swa
 hili-Lexeme. Wörterbucheinträge sind rar und Definitionen noch rarer\, sag
 t SPARQL\, Das ist ein echtes Problem. Denn schließlich bedeuten mehr Swah
 ili-Daten in Wikidata auch mehr Swahili im Semantic Web.\n\nMit Wikifuncti
 ons könnten wir Funktionen bauen\, die automatisch Sätze wie einen Wikpedi
 a-Artikela    nfang erzeugen ("Nairobi ist eine Stadt”)\, zum Beispiel in 
 Swahili\, auf Knopfdruck! Stell dir vor\, ein Wikifunction-Generator erzeu
 gt Swahili-Sätze\, während Wikidata die nötigen Lexeme stellt. Das klingt 
 wie ein Märchen? Wenn wir kollaborativ zusammenarbeiten\, kann es Wirklich
 ket werden.\n

DESCRIPTION:Internet Governance beeinflusst\, wie offen\, sicher und zugäng
 lich das Internet ist – von technischen Standards über Plattformregulierun
 g bis hin zu Fragen von Macht und Teilhabe. In diesem interaktiven Ask Me 
 Anything-Workshop laden wir Teilnehmende dazu ein\, ihre Fragen\, Zweifel 
 und Kritik rund um Internet Governance einzubringen (unabhängig von Vorwis
 sen).\n\nDer Workshop bietet einen niedrigschwelligen Einstieg in zentrale
  Akteure\, Prozesse und Konfliktlinien der Internet Governance (z. B. Mult
 istakeholder-Ansatz\, Staaten vs. Tech-Konzerne\, Global Digital Compact\,
  WSIS\, IETF\, ICANN\, W3C\; und noch viel mehr Abkürzungen). Gleichzeitig
  ist Raum für vertiefende Diskussionen\, persönliche Erfahrungen und aktue
 lle politische Aushandlungen. Ziel ist es\, Internet Governance entmystifi
 zieren\, Machtstrukturen sichtbar zu machen und gemeinsam zu diskutieren\,
  wie eine gerechtere und inklusivere digitale Zukunft aussehen kann.\n

DESCRIPTION:The session title is fashioned after the Kenyan movement buildi
 ng rhetoric “Hatupangwingwi” which is Kenyan slang meant as a call to acti
 on to counter anti-movement building techniques by the political class and
  resist infiltration and corruption. This is true for the organisation and
  movement building towards inclusive identity regimes in Kenya. \nThe sess
 ion seeks to explore the lessons from Kenya’s journey to digitalization of
  public services  and the uptake of Digital Public infrastructure. It digs
  deeper on the power of us and how civil society could stop a destructive 
 surveillance driven digitalisation thus protecting millions of Kenyans.\nI
 n 2019\, the Kenyan government announced the transition to a centralised d
 atabase named National integrated Identity management system (Huduma Namba
 ) in a bid to develop a digital Identity system that went on to be termed 
 a “single source of truth. Historically\, Kenya has not had the best track
  record with civil registration and identity systems. This is particularly
  due to the linkages with colonial practices with the first ID “Kipande” b
 eing used as a tool for surveillance of natives and imposed for restrictio
 n of movement. This system carried on post independence creating different
  classes of citizens in terms of access to nationality documents. \nIt is 
 for this reason that CSOs\, mostly community-based\, chose a three pronged
  approach to counter this\; seeking legal redress\, grassroots/community m
 obilization and advocacy and spotlighting ways in which in a shrinking civ
 il society space\, Kenyan civil society was able not only take up space\, 
 but make their impact felt in protecting the rights of those on the margin
 s. The session shares lessons of how we shaped the Media narrative that to
 ok down a multi million dollar project that was not people centered but ra
 ther oppression driven. This session shares experiences of how we created 
 a heightened sense of citizenry awareness to shoot down oppressive digital
 isation agendas. \nThe aim is to show how these efforts led to over 10 mil
 lion Kenyans resisting to enroll in the system especially the young people
  (Gen Z) who felt they were being coerced to join a system due to the poor
  messaging by the government and they connected with the NGO campaign thus
  choosing to resist the system in the true spirit of Hatupangwingwi\,  wit
 h Hashtags like [#DOIDRIGHT](https://events.ccc.de/congress/2025/hub/tag/D
 OIDRIGHT) and [#DEPORTME](https://events.ccc.de/congress/2025/hub/tag/DEPO
 RTME) trending on social media as a sign of resistance. This led to the co
 llapse of the whole project.\nFinally\, the session will share how in 2022
 \, when the new government wanted to roll out the new DPI project known as
  Maisha Namba\, they realised the importance of including civil society vo
 ices and they convened over 50 NGOs to try to build buy-in for the new dig
 ital ID program. It was the first time the government and NGOs were on the
  same table discussing how to build an inclusive digital ID system. This i
 s the story of how the power of us led to civil society earning their spac
 e in the designing phase of the new Digital Public Infrastructure.\n

DESCRIPTION:In 2022\, CitizenLab contacted a member of the Spanish non-prof
 it Irídia to tell them that one of their members had likely been hacked wi
 th Pegasus spyware. The target\, a lawyer\, had been spied on by the Spani
 sh government in 2020 because he represented a Catalan politician who was 
 in prison. His phone was infected with Pegasus during the COVID-19 lockdow
 n\, on the same day he was having an online meeting with other lawyers wor
 king on the case.\n\nIrídia and the lawyer (Andreu) decided to take the ca
 se to court. A few years later\, he met with Data Rights and invited them 
 to join forces and bring in partners from across Europe to increase the im
 pact. This collaboration led to the creation of the PEGA coalition in May 
 2025.\n\nThis talk goes over the status of the case and work we have done 
 across Europe to bring spyware use in court.\nDespite the European Parliam
 ent’s PEGA investigation in 2023\, spyware scandals in Europe continue to 
 grow\, with little real action to stop or address them. Many EU countries 
 were — or still are — clients of the world’s major spyware companies. As a
  result\, nothing changes except the number of victims targeted by these t
 echnologies. Worst\, offices or clients in the EU is useful for spyware co
 mpanies' sales pitch. So\, the EU is a growing hub for this ominous ecosys
 tem! With no real political will to act\, members of the PEGA investigatio
 n say the only hope for change is to take these cases to court — and that’
 s exactly the path we’ve chosen!\n\nIrídia’s case is one of the flagship c
 ases in the EU\, both for its depth and for what it has achieved so far. W
 e will review the current status and implications of the case\, examining 
 issues that range from state responsibility to the role of the spyware com
 pany behind Pegasus — in its creation\, sale\, and export — which maintain
 s a strong presence within the EU.\n\nAfter that\, we will take a step bac
 k to look at what is happening across Europe. We will highlight the most s
 ignificant cases currently moving forward\, as well as some of the PEGA co
 alition’s strategies for driving accountability\, strengthening safeguards
 \, and ensuring remedies. The coalition’s mission goes beyond legal action
  — it aims to prevent the devastating impact of spyware and push for syste
 mic change.\n

 ission has ever gone before. What exactly happened remains a mystery to th
 is day\, but the space probe managed to take a 2.3 m long drill core from 
 the Lunar regolith\, packaged the sample in a genius way and launched it f
 or its voyage to Earth. Some days later the sample entered earths atmosphe
 re and landed in remote Siberia and ended up in our hands more than 50 Yea
 rs later. We tell the story of the sample\, the people that brought it to 
 Earth and how we analyzed it with the newest methods including µm sized hi
 gh intensity X-ray beams\, 30kV electron beams and LN2 cooled infrared spe
 ctrometers.\nIn this talk\, members of the Museum for Natural History in B
 erlin will present the story of a Luna 24 sample retrieved by the GDR from
  the USSR. The sample has been almost "lost" to time. When it fell into ou
 r hands\, we started understanding its historical and scientific significa
 nce\, produced specialized sample containers and initiated curation effort
 s of the sample while slowly understanding its history and geochemical com
 position.\n\n### Luna 24 Moon Mission\nWhat happened on the 18th & 19th of
  August 1976 on the moon? Why was this landing site chosen and how was the
  sample retrieved and brought back to Earth? Which way did the scientists 
 handle these extremely precious samples? Picture: Музей Космонавтики (CC0

 ew information from such a sample without destroying it? Which storage and
  curation methods must be used to preserve its value for the scientists th
 at come after us? How did advanced analytical methods like µCT\, electron 
 microscopes\, µ X-ray fluorescence spectrometers and nitrogen-cooled infra

DESCRIPTION:**Over the past few decades\, nucleic acids have increasingly b
 een investigated as alternative data storage media and platforms for molec
 ular computing. This talk builds on past research and introduces another b
 ranch to the field: DNA cryptography based on random chemistry. This techn
 ology provides a platform for conceiving new security architectures that b
 ridge the physical with the digital world.**\nNucleic acids have been theo
 rized as potential data storage and computation platforms since the mid-20
 th century. In the meantime\, notable advances have been made in implement
 ing such systems\, combining academic research with industry efforts. \nAf
 ter providing a general introduction to the interdisciplinary field of DNA
  information technology\, in the second half of the talk focuses on DNA-ba
 sed cryptography and security systems\, in particular zooming in on the ex
 ample of chemical unclonable functions (CUFs) based on randomly generated\
 , synthetic DNA sequences. Similar to Physical Unclonable Functions (PUFs)
 \, these DNA-based systems contain vast random elements that cannot be rec
 onstructed – neither algorithmically nor synthetically. Using biochemical 
 processing\, we can operate these systems in a fashion comparable to crypt
 ographic hash functions\, enabling new authentication protocols. Aside fro
 m covering the basics\, we delve into the advantages\, as well as the draw
 backs\, of DNA as a medium. Finally\, we explore how CUFs could in the fut
 ure be implemented as physical security architectures: For example\, in an
 ti-counterfeiting of medicines or as personal signatures for artworks. \nI
 n a broader sense\, this talk aims to inspire a reconsideration of entropy
 \, randomness and information in the experimental sciences through a digit
 al lens. In doing so\, it provides examples of how looking at physical sys
 tems through an information perspective can unravel new synergies\, applic
 ations and even security architectures.\n

DESCRIPTION:What does knitting have to do with espionage? Can embroidery he
 lp your mental health? This talk shows how the skills to create textile ar
 t have enabled people to resist and to persist under oppressive regimes fo
 r centuries. And it offers ways to keep doing so.\nWorking with textile me
 diums like yarn\, thread\, and floss is generally seen as a feminine hobby
  and as thus is usually classified as craft\, not art. And crafting is som
 ething people\, maybe even people usually seen as a bit boring\, do in the
 ir free time to unwind. Most of us have grown up with the image of the lov
 ing grandmother knitting socks for the family\, an act of care that was ne
 ver considered anything special.\nThe patriarchal society’s tendency to un
 derestimate anything considered feminine and\, inextricably connected to t
 his\, domestic is an ongoing struggle. But being underestimated also provi
 des a cover and with it the opportunity for subversion and resistance.\nAs
  global powers are cycling back to despotism and opression\, let me take y
 ou back in time to show you how people used textile crafts to organise res
 istance and shape movements. Like the quilts that were designed and sewn t
 o help enslaved people in the US escape slavery and navigate the Undergrou
 nd Railroad from the 1780s on\, or the knitted garments that carried infor
 mation about the Nazis to help resistance in occupied Europe during World 
 War II\, or the cross stitches by a prisoner of war that had Nazis unknowi
 ngly display art saying “Fuck Hitler”.\nTextile crafts have been used by m
 arginalised and disenfranchised people to protest\, to organise\, and to p
 ersist for centuries. This tradition found a new rise in what is now calle
 d “craftivism” and is using the internet to build bigger communities spann
 ing the world. These communities also come together to help\, often quite 
 tangibly by creating specific items like the home-sewn masks during early 
 Covid19. In addition\, crafting has scientifically-proven benefits for one
 ’s mental health.\nTaking up the increasingly popular quote "When the worl
 d is too scary\, too loud\, too much: Stop consuming\, start creating"\, t
 his talk shows how the skills to create have enabled and will enable peopl
 e to resist and to persist.\n

DESCRIPTION:Factorio ist ein Fabriksimulationsspiel mit integriertem Logiks
 ystem. Dies ermöglichte mir den Bau einer CPU\, die unter anderem aus eine
 r 5-stufiger Pipeline\, einer Forwarding Logikeinheit\, Interrupt Handling
  sowie einem I/O Interface besteht. Über einen selbst geschriebenen Assemb
 ler konnte ich ein eigenes Betriebssystem und Programme wie Minesweeper od
 er Snake integrieren. \nDer Talk soll euch zeigen\, wie sich klassische Co
 mputerarchitektur in einem völlig anderen technischen Kontext umsetzen läs
 st und wo dabei überraschend echte Probleme der CPU-Entwicklung auftreten.
 \nKommt mit auf die Reise: Vom Blick auf den gesamten Computer bis hinunte
 r zu den einzelnen Logikgattern ist es nur eine Mausradbewegung entfernt!\
 nFactorio ist ein Spiel über Fabrikautomation - Förderbänder\, Dampfmaschi
 nen und Produktionsketten stehen im Vordergrund. Eigentlich ist das intern
 e Logiksystem („Combinators“) gedacht für die Steuerung der Fabrik\, jedoc
 h erlaubt es auch die Entwicklung komplexer Hardware.\n\nIn diesem Vortrag
  erzähle ich meine Geschichte\, wie ich eine vollständige RISC-V-Architekt
 ur in Factorio  rein aus Vanilla-Combinators erschaffen habe:\nDie CPU arb
 eitet mit 32 Bit-Wörtern\, verfügt über 32 General Purpose Register\, 128 
 KB RAM/Persistent Storage\, eine 5-stufige Pipeline mit Forwarding und Haz
 ard-Handling sowie eine Logikeinheit für Branches und Interrupts. Ein Disp
 lay-Controller steuert eine Konsolen-Ausgabe sowie ein Farbdisplay\, währe
 nd ein Keyboard-Controller Eingaben über physische In-Game-Tasten ermöglic
 ht.\n\nErgänzt wird die Hardware auf der Softwareseite durch das Betriebss
 ystem *FactOS*\, das ein einfaches Filesystem sowie Systemcalls (zum Beisp
 iel zum Drucken eines Strings im Terminal) zur Verfügung stellt.  Außerdem
  schränkt das Betriebssystem das ausführende User-Programm auf einen feste
 n Bereich des RAMs ein und verhindert so direkten Zugriff auf die Hardware
 .\n\nIm Talk möchte ich euch durch alle Schichten dieser Konstruktion führ
 en:\nVon den Grundlagen der Factorio-Signalphysik über CPU-Design und Pipe
 line-Hazards bis zur Toolchain und dem Betriebssystem. Außerdem gebe ich e
 inen Einblick\, wie die Limitierungen aber auch die Vorteile von Factorio 
 im Vergleich zu herkömmlichen Logik Simulatoren das Design einer CPU beein
 flussen können. Ich runde meinen Talk mit einer Live-Demonstration des Sys
 tems ab.\n\nDie vollständige CPU\, inklusive Quellcode des Assemblers\, Bl
 ueprints und Beispielprogramme\, stelle ich öffentlich zur Verfügung. Dadu
 rch kann jede interessierte Person die Architektur in Factorio laden\, erw
 eitern und eigene Software dafür entwickeln.\n\nEs wird im Anschluss eine 
 [Self-organized Session](https://events.ccc.de/congress/2025/hub/en/event/
 detail/cpu-entwicklung-in-factorio-wie-benutze-ich-phds-f) geben\, in der 
 ich eine hands-on Einleitung geben werde\, wie man die CPU in Factorio läd

DESCRIPTION:Textiles are everywhere\, yet few of us know how they’re made. 
 \n\nThis talk aims to give you an overview over the complete transformatio
 n from fiber to finished textile. We'll be exploring fiber properties\, sp
 inning\, and techniques like weaving\, knitting\, crochet\, braiding\, and
  knotting\, followed by finishing methods such as dyeing\, printing\, and 
 embroidery.\n\nYou’ll learn why not only fiber but also structure matters\
 , and how to make or hack textiles on your own without relying on fast fas
 hion or industrial tools.\nTextiles play an integral part in our daily liv
 es. If you’re reading this\, chances are you’re wearing clothes or have so
 me form of fabric within arm’s reach. Yet despite how common and essential
  textiles are\, few of us know how they actually come to be. How do we go 
 from a plant\, animal\, or synthetic polymer to a fully finished piece of 
 clothing?\n\nThis talk unravels the full transformation pipeline of textil
 es: starting with fibers and their properties\, then spinning them into ya
 rn\, turning that yarn into textiles through weaving\, knitting\, crochet\
 , braiding\, knotting\, and other techniques\, and finally finishing them 
 through printing\, embroidery\, dyeing\, or bleaching.\nAlong the way\, yo
 u’ll learn why your “100% cotton” garments can feel completely different d
 espite being made of the same fiber\, how structure matters just as much a
 s material\, and what environmental impact different choices have.\n\nWhet
 her you want to make your own textiles\, hack existing ones\, or finally u
 nderstand why that wool sweater you washed too hot is now tiny\, this talk
  is a crash course in most things textile\, and a reminder that you don’t 
 need industrial machinery or fast fashion to create something on your own.

DESCRIPTION:Generative AI models don't operate on human languages – they sp
 eak in **tokens**. Tokens are computational fragments that deconstruct lan
 guage into subword units\, stored in large dictionaries. These tokens enco
 de not only language but also political ideologies\, corporate interests\,
  and cultural biases even before model training begins. Social media handl
 es like *realdonaldtrump*\, brand names like *louisvuitton*\, or even *!!!
 !!!!!!!!!!!!!* exist as single tokens\, while other words remain fragmente
 d. Through various artistic and adversarial experiments\, we demonstrate t
 hat tokenization is a political act that determines what can be represente
 d and how images become computable through language.\nTokens are the fragm
 ents of words that generative models use to process language\, the step th
 at breaks text into subword units before any neural networks are involved.
  There are 51 ways to combine tokens to spell the word giraffe using exist
 ing vocabulary: from a single token **giraffe** to splits using multiple t
 okens like *gi|ra|ffe*\, *gira|f|fe*\, or even *g|i|r|af|fe*.\n\nIn one ex
 periment\, we hijacked the prompting process and fed token combinations di
 rectly to text-to-image models. With variations like *g|iraffe* or *gir|af
 fe* still generating recognizable results\, our experiments show that the 
 beginning and end of tokens hold particular semantic weight in forming gir
 affe-like images. This reveals that certain images cannot be generated thr
 ough prompting alone\, as the tokenization process sanitizes most combinat
 ions\, suggesting that English\, or any human language\, is merely a subse
 t of token languages.\n\nThe talk features experiments using genetic algor
 ithms to reverse-engineer prompts from images\, respelling words in token 
 language to change their generative outcomes\, and critically examining to
 ken dictionaries to investigate edge cases where the vocabulary breaks dow
 n entirely\, producing somewhat *speculative languages* that include stran
 ge words formed at the edge of chaos where English meets token (non-)sense
 .\n\nThese experiments show that even before generation occurs\, token dic
 tionaries already encode a stochastic worldview\, shaped by the statistica
 l frequencies of their training data – dominated by popular culture\, bran
 ds\, platform-speak\, and *non-words*. Tokenization is\, therefore\, a pol
 itical act: it defines what can be represented and how the world becomes c
 omputationally representable. We will look at specific tokens and ask: Whi
 ch models use which vocabularies? What *non-word* tokens are shared among 
 models? And how do language models make sense of a world using a language 
 we do not understand?\n

  there... and then brainstorm together about where the journey could take 
 us. From F/X to a bit of creative electronics\, innovative event technolog
 y\, to 3D printing and digital simulations. We are looking for elegant pro
 gramming and realistic DIY constructions! So if you feel like brainstormin
 g creative workarounds and maybe even implementing them with and for CADUS

DESCRIPTION:Entdecke das wahrscheinlich lustigste Instrument der Welt\, die
  Nasenflöte! Nach einer kurzen Einführung übt jede*r in eigenem Tempo die 
 ersten Töne. Klappt das Tröten\, geht’s weiter mit einfachen Melodien – un
 d schließlich spielen wir gemeinsam als Nasenflöten-Orchester beliebte Son
 gs und Wunschmelodien.  Lustig\, überraschend\, musikalisch – und garantie
 rt einmalig!\nWelcome to what is probably the world's only orchestra where
  the most important sound-producing instrument is... your nose! Each parti
 cipant receives a fresh nose flute and easy-to-understand instructions on 
 how to correctly position\, breathe\, and blow this wondrous instrument.  
 Then it's time to learn by sniffing! Everyone practices at their own pace 
 how to conjure up individual notes cleanly from their nose—from a delicate
  peep to a confident TOOT.  Once everyone has got the hang of it (and the 
 first tears of laughter have dried)\, we venture into simple sequences of 
 notes that already sound suspiciously like music. And if that works well\,
  it gets really epic: We transform ourselves into a nose flute a cappella 
 orchestra\, where everyone can suggest melodies – from children's songs to
  epic film themes. Together\, we make the air vibrate!  In short: A worksh
 op full of fun\, tooting noises\, unexpected talents – and real music from
  the nose.\n

DESCRIPTION:**39C3 LED badge -- SMD for Beginners**  \n\nThe 39C3 LED badge
  contains 42 LEDs that blink under control of of a pre-programmed 4 cent m
 icrocontroller. When the badge is alone\, the LEDs will blink randomly. Wh
 en it is among friends (when there are other badges nearby)\, it will disp
 lay a chaser pattern. \n\nIn this workshop you will learn how to solder Su
 rface Mounted Devices using a normal soldering iron.\n\nSuitable for begin
 ners. Under 16s only with responsible adult supervision.\n### 39C3 LED bad
 ge -- SMD for Beginners\n\n![39C3 LED badge](https://usercontent.events.cc
 c.de/congress/2025/hub/usercontent/b/7dccaedbb7ec/39C3badge.png)\n\nSurfac
 e Mounted Devices (SMDs) are small compared to Through Hole (TH) electroni
 c components\, and have the reputation of being difficult to work with as 
 a hobyist: Difficult to see and handle\, when you sneeze\, you loose them 
 and you can not easily use them on 2.54mm raster prototyping boards.\n\nSM
 D components are designed to be used in a reflow soldering process where t
 iny dots of solder paste are applied to a Printed Circuit Board (PCB)\, af
 ter which the SMD components are "Picked and Placed" on the PCB\, after wh
 ich the whole PCB is heated to the melting point of the solder ("reflowing
 ")\, actually completing the  electrical connections.\n\nThis workshop is 
 aimed at showing you that the reputation of being difficult to work with i
 s a bit undeserved\, and that you can also work with SMDs using just a  re
 gular soldering iron: With some simple tricks and a suitable selection of 
 components (not the smallest possible)\, the vast majority of people can s
 uccessfully complete this project.\n\nBeing able to solder SMD projects us
 ing just a simple soldering iron will also help you develop some skills th
 at are useful if you  need to do "rework" on reflow soldering projects. Re
 flow soldering is also not difficult to do as a hobbyist\, but requires a 
 few more tools like a stencil to apply solder paste and either an oven or 
 a hot plate to do the reflowing. It is\, however\, much quicker than solde
 ring the parts one by one\, and can yield more professional looking\, clea
 ner\, solder joints.\n\nThe project is an electronic name-badge - You shou
 ld write your name (or nick) on it and wear it. It contains 42 LEDs\, a mi
 crocontroller\, some support components and an InfraRed transmitter and re
 ceiver that allow it to communicate with other badges. When the badge dete
 cts the presence of other badges ("friends") nearby\, it will change its b
 ehaviour. It will not only interact with other 39C3 LED badges\, but also 
 with TBD badges - come visit the TBD assembly at komona or https://tbd.cam
 p\n\n![TBD badge](https://usercontent.events.ccc.de/congress/2025/hub/user
 content/e/d619de5f1be1/tbdbadge.png)\n\n### Costs\nThis workshop is donati
 on based. Materials costs are 2 euro per badge. Donations will go towards 
 1) covering costs of the badges\, 2) covering costs of running the hardwar
 e hacking area in general\, 3) covering costs of organizing TBD (see the T
 BD assembly at komona or https://tbd.camp)\n\n### Registration\nThe number
  of participants per session is limited. First come\, first served. Either
  get a participation voucher beforehand or show up early (there may be pla
 ces left).\nThere will be *numbered* paper vouchers available for each ses
 sion some time in advance of each session. If you get a voucher and do not
  show up *before* the designated starting time\, someone else may take you
 r spot. Please don't take multiple vouchers and don't take  vouchers if yo
 u don't actually plan to participate.\n\n### Getting a kit\nKits are part 
 of the workshop and not for sale separately. You can\, however easily sour
 ce your own PCBs and parts and make kits yourself because the design is  M
 IT licensed open source.\n\n### Links\nUnder construction: https://hackwin

DESCRIPTION:This talk demonstrates end-to-end prompt injection exploits tha
 t compromise agentic systems. Specifically\, we will discuss exploits that
  target computer-use and coding agents\, such as Anthropic's Claude Code\,
  GitHub Copilot\, Google Jules\, Devin AI\, ChatGPT Operator\, Amazon Q\, 
 AWS Kiro\, and others. \n\nExploits will impact confidentiality\, system i
 ntegrity\, and the future of AI-driven automation\, including remote code 
 execution\, exfiltration of sensitive information such as access tokens\, 
 and even joining Agents to traditional command and control infrastructure.
  Which are known as "ZombAIs"\, a term first coined by the presenter as we
 ll as long-term prompt injection persistence in AI coding agents.\n\nAddit
 ionally\, we will explore how nation state TTPs such as ClickFix apply to 
 Computer-Use systems and how they can trick AI systems and lead to full sy
 stem compromise (AI ClickFix). \n\nFinally\, we will cover current mitigat
 ion strategies and forward-looking recommendations and strategic thoughts.
 \nDuring the Month of AI Bugs (August 2025)\, I responsibly disclosed over
  two dozen security vulnerabilities across all major agentic AI coding ass
 istants. This talk distills the most severe findings and patterns observed
 .\n\nKey highlights include:\n* Critical prompt-injection exploits enablin
 g zero-click data exfiltration and arbitrary remote code execution across 
 multiple platforms and vendor products\n* Recurring systemic flaws such as
  over-reliance on LLM behavior for trust decisions\, inadequate sandboxing
  of tools\, and weak user-in-the-loop controls.\n* How I leveraged AI to f
 ind some of these vulnerabilities quickly\n* The AI Kill Chain: prompt inj
 ection\, confused deputy behavior\, and automatic tool invocation\n* Adapt
 ation of nation-state TTPs (e.g.\, ClickFix) into AI ClickFix techniques t
 hat can fully compromise computer-use systems.\n* Insights about vendor re
 sponses: from quick patches and CVEs to months of silence\, or quiet patch
 ing\n* AgentHopper will highlight how these vulnerabilities combined could
  have led to an AI Virus\n\nFinally\, the session presents practical mitig
 ations and forward-looking strategies to reduce the growing attack surface
  of probabilistic\, autonomous AI systems.\n

DESCRIPTION:Both within the EU as well as nationally in Germany\, there exi
 sts a renewed drive to implement data retention\, a practice struck down b
 y the ECJ and discontinued in many national legislations. In parallel\, cr
 oss-border access to stored data has been mandated within the EU as “e-evi
 dence”\, and will soon be extended to 90+ countries under the umbrella of 
 the EU cybercrime convention. In principle\, all data stored by service pr
 oviders will be available to law enforcement as part of a criminal investi
 gation. The timing of both initiatives is not coincidental\, as access to 
 data naturally relies on the availability of data.\nThe talk will address 
 the state of play on data retention in various legislations\, and introduc
 e the practice of cross border access to stored data by law enforcement as
  well as its shortcomings and threats to privacy and confidentiality.\nThe
  Specter of Data Retention is back in the political arena\, both as a harm
 onized\, EU-wide approach as well as being part of the coalition agreement
  of the new German national government. Other countries have already recen
 tly implemented new data retention laws\, i.e. Belgium or Denmark. \nIn pa
 rallel\, access to all types of stored data – and not only data stored und
 er a data retention regime – by law enforcement has been radically reforme
 d by groundbreaking new legislation\, undermining both exiting national sa
 feguards as well as protections implemented by businesses aiming for a hig
 her standard in cyber security and data protection.  \nThe talk will give 
 an overview on recent developments for a harmonized “minimum” approach to 
 data retention under the Polish and Danish EU presidency as well as the ne
 w German legislation currently under consideration. \nIt will introduce th
 e upcoming international release mechanisms for stored data under the e-ev
 idence legislation\, the 2nd protocol to the EU cybercrime convention as w
 ell as future threats from the UN cybercrime convention. \nIt will address
  how a cross-border request for information works in practice\, which type
 s of data can be requested by whom\, and who will be responsible for the f
 ew remaining safeguards – including an analysis of the threat model and po
 tential “side channel” attacks by cybercrime to gain access to basically a
 ll data stored by and with service providers.\n

DESCRIPTION:The talk will be about our experience from building an open-arc
 hitecture secure element from the ground up. It explains why openness beca
 me part of the security model\, how it reshaped design and development wor
 kflows\, and where reality pushed back — through legal constraints\, third
 -party IP\, or export controls. It walks through the secure boot chain\, a
 ttestation model\, firmware update flow\, integration APIs\, and the testi
 ng framework built for external inspection. Real examples of security eval
 uations by independent researchers are presented\, showing what was learne
 d from their findings and how those exchanges raised the overall security 
 bar. The goal is to provoke discussion on how open collaboration can make 
 hardware more verifiable\, adaptable\, auditable and while keeping secure.
 \nThis talk shares our engineering experience from designing and implement
 ing an open-architecture secure element — a type of chip that is tradition
 ally closed and opaque. We’ll outline the practical consequences of choosi
 ng openness as part of the security model: how it affected hardware archit
 ecture\, firmware design\, verification\, and development workflows.\nThe 
 session dives into concrete technical areas including the secure boot chai
 n\, attestation and update flow\, key storage isolation\, and the testing 
 and fuzzing infrastructure used to validate the design. It also covers the
  boundaries of openness — where third-party IP\, export control\, or certi
 fication requirements force certain blocks to remain closed — and how we d
 ocument and mitigate those limits.\nWe’ll present anonymized examples of e
 xternal security evaluations\, show how responsible disclosure and transpa
 rent fixes improved resilience\, and reflect on what “community-driven sec
 urity” means in a hardware context. Attendees should leave with a clearer 
 view of what it takes to make security verifiable at the silicon level — a
 nd why that process is never finished.\n

DESCRIPTION:A brief history of typographic misbehavior or intended and unin
 tended uses of variable fonts.\n\nNine years after the introduction of var
 iable fonts\, their most exciting uses have little to do with what variabl
 e fonts originally were intended for and their original promise of smaller
  file sizes. The talk looks at how designers turned a pragmatic font forma
 t into a field for experimentation — from animated typography and uniwidth
  button text to pattern fonts and typographic side effects with unintended
  aesthetics. Using examples from projects such as TypoLabs\, Marjoree\, Ka
 rio (the variable font that’s used as part of the 39C3 visual identity)\, 
 and Bronco\, we’ll explore how variable fonts evolved from efficiency tool
 s into creative systems — and why the most interesting ideas often emerge 
 when technology is used in unintended ways.\nWhen the OpenType 1.8 specifi
 cation introduced variable fonts in 2016\, the idea was simple: combine al
 l weights and styles of a font family into one file and save file size and
  therefore bandwidth. Yet in 2025\, variable fonts have become a platform 
 for artistic and technical exploration far beyond their initial goal.\n\nT
 his talk follows that transformation from the inside. It starts with a sho
 rt history of flexible font technologies — Adobe’s Multiple Master and App
 le’s TrueType GX formats of the 1990s (I am just mentioning the company na
 mes as they were the publishers of these technologies) — and how they fail
 ed to become standards. It then shows why variable fonts succeeded: many d
 esigners today are more tech savvy and know some basic HTML\, CSS and mayb
 e even some JavaScript. And at the same time all major browsers and almost
  all design apps support variable fonts  by now.\n\nFrom there\, I present
  a series of first-hand projects where typography met code:\n– TypoLabs (2
 017)\, whose identity used a custom variable font animating between extrem
 es of weight and width → the variable font family became the (probably for
 ever) unpublished variable font family Denman\;\n– Marjoree (2024)\, a pai
 r of variable pattern fonts based on hexagonal and pentagonal tilings that
  explore legibility and repetition\;\n– Kario (2025)\, a duplex variable f
 ont powering the 39C3 identity\, with uniwidth weights\, optical-size adju
 stments\, and typographic Easter eggs\;\n– and Bronco (2017?)\, an experim
 ent using the arbitrary-axis model for interpolation to escape the cube-sh
 aped multiple master design space of traditional variable fonts.\n\nThe ta
 lk then moves from history to speculation. Early head-tracking experiments
  once tried to adjust a variable font’s optical size based on reader posit
 ion — producing total chaos as text reshaped itself while being read. On t
 he other hand this playful chaos marks the moment when things become truly
  interesting: connecting a font axis to live data\, to mouse movement\, to
  sound\, to network input — anything that makes type responsive and alive.
  That’s the kind of misbehavior I want to talk about — not breaking for th
 e sake of breaking\, but using technology the “wrong” way to see what happ
 ens.\n\nThe talk will mix images\, a lot of short videos\, and a bit of be
 hind-the-scenes insight into font development. It’s about what happens whe
 n design tools meet code\, and how that intersection keeps typography aliv
 e and unpredictable.\n\nLink list of variable font experiments:\nhttps://k

DESCRIPTION:This talk explores the internals of Overwatch which make the ga
 me work under the hood. \n\nThe end goal is to democratise development of 
 Overwatch. Being able to host your own servers and modify the game client 
 to your liking should not be up for discussion for a game many people have
  paid money for.\nHey you! Yes you! Do you want to pay for a game which ge
 ts forcibly taken away from you after only six years? Do you want to buy l
 ootboxes in order to unlock cosmetics faster in the game you „own“?\n\nOve
 rwatch 1 was released in 2016 to critical acclaim and millions of sales gl
 obally. It has permanently changed the hero-shooter landscape which was in
  much need of a fresh new game and playstyle. After a few hard years plagu
 ed with infrequent updates\, long overdue hero nerfs / reworks and broken 
 promises\, Overwatch 1 was finally taken offline on October 3\, 2022.\n\nE
 ver since I started playing Overwatch I was fascinated by the game and it’
 s proprietary engine\, Tank. Not much is known about it\, only that core c
 omponents were reused from the cancelled Blizzard IP\, Titan. It’s a shame
  that this game (engine) is not getting the recognition it deserves. From 
 the entity-component architecture to the deterministic graph based scripti
 ng engine which handles (almost) everything which happens ingame\, it is a
  truly refreshing take on networking and game programming rarely seen in g
 ames. So\, considering this\, building a game server from scratch can’t be
  that hard\, riiiight?\n\nJoin me in this documentation of my gradual desc
 ent into madness while I (jokingly) roast Overwatch developers for code wh
 ich they probably do not even remember that theyve written 10+ years ago :

 still publicly available version which I could find\, 0.8.0.0 Beta (0.8.24

DESCRIPTION:"Don't roll your own crypto" is an often-repeated aphorism. It'
 s good advice -- but then how does any cryptography get made? Writers of c
 ryptography code like myself write code with bugs just like anyone else\, 
 so how do we take precautions against our own mistakes? In this talk\, I w
 ill give a peek into the cryptographer's toolbox of advanced techniques to
  avoid bugs: targeted testing\, model checking\, mathematical proof assist
 ants\, information-flow analysis\, and more. None of these techniques is a
  magic silver bullet\, but they can help find flaws in reasoning about tri
 cky corner cases in low-level code or prove that higher-level designs are 
 sound\, given a defined set of assumptions. We'll go over some examples an
 d try to give a high-level feel for different workflows that create "high-
 assurance" code. Whether you know it or not\, you use this type of cryptog
 raphy code every day: in your browser\, your messaging apps\, and your fav
 orite programming language standard libraries.\nOver the last 10 years or 
 so\, using mathematical proof assistants and other formal-logic tools for 
 cryptography code has gone from a relatively new idea to standard practice
 . I've been lucky enough to have a front-row seat to that transformation\,
  having started doing formal-methods research in 2015 and then switched to
  a focus on cryptography implementation since 2021. Code from my master's 
 thesis project\, ["fiat-crypto"](https://github.com/mit-plv/fiat-crypto)\,
  is [included](https://andres.systems/fiat-crypto-adoption.html) in every 
 major browser as well as AWS\, Cloudflare\, Linux\, OpenBSD\, and standard
  crypto libraries for Go\, Zig\, and Rust (RustCrypto\, dalek). In additio
 n to verifying code correctness\, designers of high-level protocols like S
 ignal's recently announced post-quantum ratchet increasingly use mathemati
 cal tools (ProVerif in Signal's case) to check their work.\n\nDespite the 
 growing popularity of these formal techniques and their relevance to perso
 nal information security\, few people are aware of them\, and they maintai
 n a reputation for being hard to learn and esoteric. I'd like to demystify
  the topic and show examples of how anyone can use proof assistants in sma
 ll\, standalone ways as part of the coding or design process. My hope is t
 hat next time a colleague asks for review of a complex high-speed bit-twid
 dling algorithm\, instead of staring at the code line-by-line\, attendees 
 of my talk will know they can write a computer-checked proof to confirm or
  deny that the algorithm achieves its intended result.\n

DESCRIPTION:What happens when AI-powered criminals meet AI-powered hunters?
  A technical arms race where both sides are vibing their way through explo
 itation—and the backdoors write themselves.\n\nIn October 2025\, we invest
 igated Taiwan's fake delivery scam ecosystem targeting convenience store c
 ustomers. What started as social engineering on social media became a deep
  dive into two distinct fraud platforms—both bearing the unmistakable fing
 erprints of AI-generated code. Their developers left more than just bugs: 
 authentication flaws\, file management oversights\, and database implement
 ations that screamed "I asked LLM and deployed without reading." We turned
  their sloppiness into weaponized OSINT. Through strategic reconnaissance\
 , careful database analysis\, and meticulous operational security\, we ach
 ieved complete system access on multiple fraud infrastructures. By analyzi
 ng server artifacts and certificate patterns\, we mapped 100+ active domai
 ns and extracted evidence linking thousands of victim transactions worth m
 illions of euros in fraud. But here's the twist: we used the same AI tools
  they did\, just with better prompts.\n\nThe takeaway isn't just about hun
 ting scammers—it's about the collapse of the skill gap in both offense and
  defense. When vibe coding meets vibe hacking\, the underground economy de
 mocratizes in ways we never anticipated. We'll share our methodology for f
 ingerprinting AI-assisted crime infrastructure\, discuss the ethical bound
 aries of counter-operations\, and demonstrate how to build sustainable thr
 eat intelligence pipelines when your adversary can redeploy in 5 minutes. 
 This talk proves that in 2025\, the real exploit isn't zero-day—it's zero-
 understanding.\nOur journey began with a simple question: why are so many 
 people losing money to fake convenience store delivery websites? The answe
 r led us through two distinct criminal architectures\, both exhibiting cha
 racteristics of large language model–assisted development.\n\nCase 1 ran o
 n PHP with backup artifacts exposing implementation details and query mani
 pulation opportunities. The installation package itself contained pre-exis
 ting access mechanisms—whether this was developer insurance or criminal-on
 -criminal sabotage remains unclear. We leveraged initial access to bypass 
 security restrictions using protocol-level manipulation and extracted giga
 bytes of operational data.\n\nCase 2 featured authentication bypass vulner
 abilities that granted direct administrative access. The backend structure
  revealed copy-pasted code patterns without proper security implementation
 .\n\nThroughout both systems\, we observed telltale signs of AI-generated 
 code: verbose documentation in unexpected languages\, inconsistent coding 
 patterns\, textbook-like naming conventions\, and theoretical security imp
 lementations. Even the UI revealed LLM fingerprints—overly polished compon
 ent layouts\, placeholder text patterns\, and design choices that felt dis
 tinctly "tutorial-like." These weren't experienced developers—they were op
 erators deploying what LLMs gave them without understanding the internals.
 \n\nThe irony? We used AI extensively too: for data parsing\, pattern reco
 gnition\, attack surface mapping\, and intelligence queries. The differenc
 e was intentionality—we understood what the output meant.\n\nUsing open-so
 urce intelligence platforms and carefully crafted fingerprints\, we mapped
  over a hundred active domains following similar patterns. Each one shared
  the same architecture\, the same weaknesses\, the same developer mistakes
 . This repeatability became our advantage. When scammers can redeploy infr
 astructure in days\, you don't attack individual sites—you automate the en
 tire reconnaissance-to-evidence pipeline.\n\nThis talk demonstrates practi
 cal techniques for mass-scale fraud infrastructure fingerprinting\, operat
 ional security considerations when investigating active criminal operation
 s\, and methods to recognize AI-generated code patterns that reveal threat
  actor sophistication. We'll discuss the ethical boundaries of counter-fra
 ud operations and evidence preservation for law enforcement\, along with a
 utomation strategies for sustainable threat intelligence when adversaries 
 rebuild faster than you can report. The demonstration will show how to go 
 from a single suspicious domain to a network map of 100+ sites and thousan
 ds of victim records—using tools available to any researcher.\n\nThis isn'
 t a story about elite hackers versus criminal masterminds. It's about two 
 groups equally reliant on AI vibing their way through technical problems—o
 ne for fraud\, one for justice. The skill barrier has collapsed. The quest
 ion now is: who has better context\, better ethics\, and better coffee?\n

DESCRIPTION:The Emergency Alert System (EAS) and its SAME (Specific Area Me
 ssage Encoding) protocol are public alerting technologies that broadcast s
 hort digital bursts over VHF triggering emergency messages on millions of 
 receivers across North America. In Mexico\, this technology was integrated
  into the Seismic Alert System (SASMEX) which more than 30 million people 
 in the central part of the country rely on to prepare for frequent earthqu
 akes.\n\nWhile new alerting technologies have emerged\, the EAS-SAME netwo
 rk continues to play an important role for public safety in the U.S.\, Mex
 ico\, and Canada. Yet\, the same small packets of bits that can help prote
 ct a city could also\, in the wrong hands\, destabilize it. This talk exam
 ines how these systems operate and reveals a troubling truth: spoofing the
 se alerts is far easier than most people expect.\nIn this talk\, we’ll beg
 in by contextualizing the importance of the seismic alert in Mexico City\,
  a system born from the devastating 1985 earthquake. We’ll examine how it 
 was designed\, how it works\, and why it carries such a deep psychological
  impact.\n\nFrom there\, we’ll explore the history and design of Weather R
 adio and the SAME protocol\, looking at how messages are transmitted and e
 ncoded through this technology\, and how it was later adapted for SASMEX.\
 n\nI’ll also share my personal experience building compatible receivers\, 
 from early open-source experiments that inspired local manufacturers to cr
 eate government-certified devices\, to developing a receiver as part of my
  undergraduate thesis.\n\nWe’ll analyze how simplicity\, one of the key st
 rengths of these systems\, also introduces certain risks\, and how these t
 rade-offs emerge when dealing with accessibility\, interoperability\, and 
 security in system design.\n\nFinally\, I’ll demonstrate how to receive\, 
 decode\, and encode these alert messages\, and discuss how\, with the righ
 t equipment\, it’s possible to generate such alert signals.\n

DESCRIPTION:[Radicle](https://radicle.xyz/) is an open source\, peer-to-pee
 r code collaboration stack built on Git. Unlike centralized code hosting p
 latforms\, such as GitHub or GitLab\, there is no single entity controllin
 g the network. Repositories are replicated across peers in a decentralized
  manner\, and users retain sovereignty over their data and workflow.\n\n*F
 ree your code!*\nToday\, much of the open-source ecosystem depends on a fe
 w centralized code forges\, even though modern version control systems are
  designed with fully distributed collaboration in mind.\nThis creates ques
 tionable dependencies with regards to governance and supply-chain security
 .\nIn this talk\, we explore an alternative: [Radicle](https://radicle.xyz
 /)\, a decentralized\, peer-to-peer code collaboration stack built on Git\
 , that empowers developers to work together while staying sovereign.\n\nUn
 like traditional\, centralized code forges that can impose censorship\, Ra
 dicle ensures that each user retains control over their data\, interaction
 s\, and collaboration\, free from corporate influence.\nThis aligns with b
 roader movements toward decentralization\, open-source software\, and the 
 democratization of internet services.\n\nWe introduce the system\, provide
  a progress update\, and share what we are currently working on.\n\nAttend

DESCRIPTION:The Bitcoin security budget has profound implications for the l
 ong term security of Bitcoin and similar proof of work cryptocurrencies. I
 n this talk we discuss the various types of transaction fee markets for di
 fferent cryptocurrencies and the possibility of transaction fees replacing
  falling block rewards to provide security in the future. The results from
  our analysis of the Monero fee market in particular do pose some very ser
 ious questions regarding the long term security and viability of cryptocur
 rencies that do not have a minimum fixed block reward or tail emission. We
  will discuss these questions and their implications for the possibility o
 f a worldwide peer-to-peer electronic cash system.\nSatoshi Nakamoto relea
 sed Bitcoin: A Peer-to-Peer Electronic Cash System\, in October 2008\, htt
 ps://bitcoin.org/bitcoin.pdf\,  during the 2008 financial crisis. The Bitc
 oin genesis block was mined in January 2009 launching the Bitcoin network.
  The design of Bitcoin has a maximum money supply of 21 million Bitcoin (B
 TC). The security budget consisting of the block reward and transaction fe
 es per block is paid to the miner (creator) of each block as an incentive 
 to secure the network. The blocks in Bitcoin are approximately every 10 mi
 nutes. The block reward is required by consensus to halve approximately ev
 ery 4 years\, starting at 50 BTC per block in 2009\, and is currently at 3
 .125 BTC per block. This leads to a current annual growth rate of the tota
 l Bitcoin money supply that is below 1%. The next halving to 1.5625 BTC is
  estimated to occur in April of 2028. Transaction fees are currently less 
 than 1% of the total Bitcoin security budget.\n\nIt is claimed in section 
 6 of the Bitcoin whitepaper that:\n\n“Once a predetermined number of coins
  have entered circulation\, the incentive can transition entirely to trans
 action fees and be completely inflation free”\;\n\nhowever no evidence\, t
 heory or references are provided to support this claim.\n\nThe above model
 \, with some variations\, has been followed by most of the top proof of wo
 rk cryptocurrencies\, including Bitcoin Cash (BCH)\, Litecoin (LTC)\, and 
 ZCash (ZEC). There are however some notable exceptions\, Dogecoin (DOGE) a
 nd Monero (XMR). Both Dogecoin and Monero have fixed block rewards. In Dog
 ecoin this was the result of a bug in the code\; however in Monero a fixed
  minimum block reward or tail emission was deliberately set at the constan
 t rate 0.6 XMR per block. The blocks in Monero are approximately every 2 m
 inutes. This leads to an annual growth rate of the total Monero money supp
 ly that is below 1%. For comparison the historical annual compounded rate 
 of growth of the gold money supply is close to 1%.\n\nThe fee market in a 
 cryptocurrency is also highly dependent on whether the blocksize is fixed\
 , as in  Bitcoin\, Dogecoin\, Litecoin and ZCash or adaptive as in Bitcoin
  Cash and Monero. In the case of adaptive blocksizes the question becomes:
  Is there a penalty (cost) to increase the blocksize as in Monero or no co
 st to increase the blocksize as in Bitcoin Cash?\n\nA balance needs to be 
 found in the design of a cryptocurrency between allowing for blocksize gro
 wth in order to support the transaction demand for peer to peer electronic
  cash\, and the necessity of spam mitigation.   The use of privacy preserv
 ing technologies can also have a profound impact on this balance\, by incr
 easing the transaction size\, while at the same time preventing the use of
  censorship\, as a means of spam mitigation. In Monero for example this in
 crease will be by a factor of around 20 times\, after the upcoming Full Ch
 ain Membership Proofs\, plus plus (FCMP++) hard fork. This makes finding t
 his balance in cryptocurrencies such as Monero with no option to opt out o
 f privacy\, by far the hardest. On the other hand a solution that works in
  Monero will also work in a cryptocurrency with a lesser degree of privacy
 .\n\nIn the presentation we will discuss the following questions:\nHow do 
 the various types of fee markets: fixed blocksize\, adaptive blocksize wit
 h penalty\, and adaptive blocksize without penalty work?\nCan transaction 
 fees replace the falling block rewards or are fixed block rewards necessar
 y?\nAre there advantages or disadvantages to replacing block rewards with 
 transaction fees?\nIs it possible to have a fixed block reward and still b
 e inflation free? \nDo we have a peer-to-peer electronic cash system or ju
 st another kind of asset for investment and speculation using centralized 
 financial institutions?\nIs a worldwide peer-to-peer electronic cash syste
 m possible now or in the foreseeable future?\n\nWe will also discuss some 
 of the broader implications\n

DESCRIPTION:In this talk\, I will describe how my team and I systematically
  exploited around a dozen home-rolled network encryption protocols used by
  popular mobile apps like RedNote\, Alipay\, and some of the most popular 
 mobile browsers in China to encrypt sensitive information. I'll demonstrat
 e how network eavesdroppers could access users' browsing history and mobil
 e activity.\n\nThis is a systemic issue\; despite our work on the above pr
 otocols and the resulting vulnerability disclosures\, this plague of home-
 rolled and proprietary encryption is still at large. I will end by discuss
 ing how we got here\, re-affirm the age-old adage\, “Don’t roll your own c
 rypto!”\, and call on hackers around the world to help us move towards HTT
 PS everywhere.\nTLS is not as universal as we might think. Applications wi
 th hundreds of millions of active users continue to use insecure\, home-ro
 lled proprietary network encryption to protect sensitive user data. This t
 alk demonstrates that this is a widespread and systemic issue affecting a 
 large portion of the most popular applications in the world. These issues 
 are particularly concentrated in mobile applications developed in China\, 
 which have been overlooked by the global security community despite their 
 massive popularity and influence.\n\nWe found that 47.6% of top Mi Store a
 pplications used proprietary network cryptography without any additional e
 ncryption\, compared to only 3.51% of top Google Play Store applications. 
 We analyzed the most popular of these protocols\, including cryptosystems 
 designed by Alibaba\, iQIYI\, Kuaishou\, and Tencent. Of the top 9 protoco
 l families\, we discovered vulnerabilities in 8 that allowed network eaves
 droppers to decrypt underlying data. We also discovered additional vulnera
 bilities in several other protocols used by apps with hundreds of millions
  of users.\n\nThrough the vulnerabilities fixed as a result of this work\,
  this research has directly improved the network security of up to one bil
 lion people. However\, there were hundreds more proprietary protocols used
  by popular applications that we discovered. Verifying all of their securi
 ty through manual reverse-engineering and vulnerability reporting is not f
 easible at this scale. What can we do as a community to fix this systemic 
 issue and prevent such failures from occurring in the future?\n

DESCRIPTION:We present a comprehensive security assessment of Unitree's rob
 otic ecosystem. We identified and exploited multiple security flaws across
  multiple communication channels\, including Bluetooth\, LoRa radio\, WebR
 TC\, and cloud management services. Besides pwning multiple traditional bi
 nary or web vulnerabilities\, we also exploit the embodied AI agent in the
  robots\, performing prompt injection and achieve root-level remote code e
 xecution. Furthermore\, we leverage a flaw in cloud management services to
  take over any Unitree G1 robot connected to the Internet. By deobfuscatin
 g and patching the customized\, VM-based obfuscated binaries\, we successf
 ully unlocked forbidden robotic movements restricted by the vendor firmwar
 e on consumer models such as the G1 AIR. We hope our findings could offer 
 a roadmap for manufacturers to strengthen robotic designs\, while arming r
 esearchers and consumers with critical knowledge to assess security in nex
 t-generation robotic systems.\nUnitree is among the highest-volume makers 
 of commercial robots\, and their newest humanoid platforms ship with multi
 ple control stacks and on-device AI agents. If the widespread\, intrusive 
 presence of these robots in our lives is inevitable\, should we take the i
 nitiative to ensure they are completely under our control? What paths migh
 t attackers use to compromise these robots\, and to what extent could they
  threaten the physical world?\n\nIn this talk\, we first map the complete 
 attack surface of Unitree humanoids\, covering hardware interfaces\, near-
 field radios and Internet-accessible channels. We demonstrate how a local 
 attacker can hijack a robot by exploiting vulnerabilities in short-range r
 adio communications (Bluetooth\, LoRa) and local Wi-Fi. We also present a 
 fun exploit of the embodied AI in the humanoid: With a single spoken/text 
 sentence\, we jailbreak the on-device LLM Agent and pivot to root-priviled
 ged remote code execution. Combined with a flaw in the cloud management se
 rvice\, this forms a full path to gain complete control over any Unitree r
 obot connected to the Internet\, obtaining root shell\, camera livestreami
 ng\, and speaker control.\n\nTo achieve this\, we combined hardware inspec
 tion\, firmware extraction\, software-defined radio tooling\, and deobfusc
 ation of customized\, VM-based protected binaries. This reverse engineerin
 g breakthrough also allowed us to understand the overall control logic\, p
 atch decision points\, and unlock advanced robotic movements that were del
 iberately disabled on consumer models like G1 AIR.\n\nTakeaways. Modern hu
 manoids are networked\, AI-powered cyber-physical systems\; weaknesses acr
 oss radios\, cloud services\, and on-device agents could allow attackers t
 o remotely hijack robot operations\, extract sensitive data or camera live
 streams\, or even weaponize the physical capabilities. As robotics continu
 e their transition from controlled environments to everyday applications\,
  our work highlights the urgent need for security-by-design in this emergi
 ng technology landscape.\n

 he global system of trade. Ironically\, it is this system that prevented a
 ll of America's trading partners from disenshittifying their internet: the
  US trade representative threatened the world with tariffs unless they pas
 sed laws that criminalized reverse-engineering and modding. By banning "ad
 versarial interoperability\," America handcuffed the world's technologists
 \, banning them from creating the mods\, hacks\, alt clients\, scrapers\, 
 and other tools needed to liberate their neighbours from the enshittificat
 ory predations of the ketamine-addled zuckermuskian tyrants of US Big Tech
 .\n\nWell\, when life gives you SARS\, you make sarsaparilla. The Trump ta
 riffs are here\, and it's time to pick the locks on the those handcuffs an
 d set the world's hackers loose on Big Tech. Happy Liberation Day\, everyo
 ne!\nEnshittification wasn't an accident. It also wasn't inevitable. This 
 isn't the iron laws of economics at work\, nor is it the great forces of h
 istory.\n\nEnshittification was a choice: named individuals\, in living me
 mory\, enacted policies that created the enshittogenic environment. They c
 reated a world that encouraged tech companies to merge to monopoly\, trans
 forming the internet into "five giant websites\, each filled with screensh
 ots of the other four." They let these monopolists rip us off and spy on u
 s.\n\nAnd they banned us from fighting back\, claiming that anyone who mod
 ified a technology without permission from its maker was a pirate (or wors
 e\, a terrorist). They created a system of "felony contempt of business-mo
 del\," where it's literally a crime to change how your own devices work. T
 hey declared war on the general-purpose computer and demanded a computer t
 hat would do what the manufacturer told it to do (even if the owner of the
  computer didn't want that).\n\nWe are at a turning point in the decades-l
 ong war on general-purpose computing. Geopolitics are up for grabs. The fu
 ture is ours to seize.\n\nIn my 24 years with EFF\, I have seen many stran
 ge moments\, but never one quite like this. There's plenty of terrifying t
 hings going on right now\, but there's also a massive\, amazing\, incredib
 ly opportunity to seize the means of computation.\n\nLet's take it. '\n

  future goals are.\n\nIn our introduction\, we will talk about the origin 
 and exploration phase of the inital pager idea (i.e. how we went from the 
 idea of bringing POCSAG Pager transmitter to 38c3\, over a cable-bound pro
 totype\, to a first working pager on a proper PCB). We will also present o
 ur plans of connecting our POCSAG transmitter infrastructure to THOT (CERT
 s own dispatch software).\n\nFor our in-depth review about the project\, w
 e explain how we encountered major reception problems\, how we analyzed th
 em at easterhegg22 and conducted experiments there\, and why we are opting
  for a custom HF frontend design instead of an already-made one from chine
 se vendors. Moreover\, we provide an overview of our transmitter devices a
 nd give some advice on how to replicate those.\n\nLastly\, we will discuss
  further challenges and what our next goals are.\n\nIf we are reaching our
  milestone until 39c3\, we will also give a live demo of the system.\nAt 3
 8c3\, we conducted an experiment to test out our self-built POCSAG Pager i
 nfrastructure. Together with DL0TUH and CERT\, we are now working on an op

DESCRIPTION:This talk presents Apple's link-layer protocol Low-Latency WiFi
  and how it achieves its real-time capabilities to enable Continuity featu
 res like Sidecar Display and Continuity Camera. We make more kernel loggin
 g available on iOS and build a log aggregator that combines and aligns sys
 tem- and network-level log sources from iOS and macOS.\nApple's Continuity
  features make up a big part of their walled garden. From AirDrop and Hand
 off to AirPlay\, they all connect macOS and iOS devices wirelessly. In rec
 ent years\, security researchers have opened up several of these features 
 showing that the Apple ecosystem is technically compatible with third-part
 y devices.\n\nIn this talk\, we present the internal workings of Low-Laten
 cy WiFi (LLW) – Apple's link-layer protocol for several real-time Continui
 ty features like Continuity Camera and Sidecar Display. We talk about the 
 concepts behind LLW\, how it achieves its low-latency requirement and how 
 we got there in the reverse engineering process.\n\nWe also present the to
 oling we built to enable more kernel-level tracing and logging on iOS thro
 ugh a reimplementation of cctool from macOS and the source code of trace t
 hat was buried deep inside of Apple’s open-source repository system_cmds. 
 We build a log aggregator that combines various kernel- and user-space tra
 ces\, log messages and pcap files from both iOS and macOS into a single fi
 le and finally investigate the network stack on Apple platforms that is im
 plemented in both user- and kernel space. There we find interesting config
 uration values of LLW that make it the go-to link-layer protocol for Apple
 's proprietary real-time Continuity applications.\n

DESCRIPTION:Why is electronics manufacturing hard? Can it ever be made easy
  and more accessible? What will it take to relocate industrial production 
 to Europe?\n\nWe share with you what we learned when we spent more than 1 
 year setting up our own production line in our office in Hamburg. Turns ou
 t a lot of the difficulties are rarely talked about or hidden behind "manu
 facturing is high CAPEX". \n\nCome and learn with us the nitty gritty deta
 ils of batch reflow ovens\, stencil printing at scale\, and how OpenPnP is
  a key enabler in our process. While we are far from done with this work\,
  we hope to see others replicate it and collectively reclaim the ownership
  of the means of electronics production.\nOur industry needs a reboot as w
 ell\, it no longer serves the people.\n\nOur work is based on our belief t
 hat high-quality high-mix/low volume manufacturing of electronics in Europ
 e is economically viable and accessible to small companies with a lower-th
 an-expected up-front investment.\n\nWe believe that relocation of industry
  to Europe depends on small innovative companies\, and will not come from 
 slow and bloated industry giants whose products are victims of enshittific
 ation and maximum profit extraction.\n\nBy using open-source hardware and 
 software whenever possible\, we are attempting to set up our own productio
 n operation in Hamburg and we want to share the solutions and enable other
 s to do the same and collectively reclaim ownership of the means of produc
 tion.\n\nWe will cover:\n- How we acquired and set up production machines\
 , their costs\, and our learnings\n- Quirks of paste printing and reflow s
 oldering at scale (up to 50 batches a day)\n- Component inventory\, tracki
 ng\, DfM\, etc.\n- How OpenPnP is a key enabler of our prcesses\n    - Our
  proposed changes to OpenPnP\n    - Our work integrated Siemens Siplace Fe
 eders in OpenPnP\n\nCheck out our ressources on the topic at https://eilbe

 es generally fall into two categories: larger devices running a full opera
 ting system using an MMU which generally means Linux\, or smaller devices 
 running without an MMU using operating systems like Zephyr\, chibios\, or 
 rt-thread\, or run with no operating system at all. The software that unde
 rpins these projects is written in C with coarse hardware memory protectio
 n at best. As a result\, these embedded OSes lack the security guarantees 
 and/or ergonomics offered by modern languages and best practices.\n\nThe X
 ous microkernel borrows concepts from heavier operating systems to moderni
 ze the embedded space. The open source OS is written in pure Rust with min
 imal dependencies and an emphasis on modularity and simplicity\, such that
  a technically-savvy individual can audit the code base in a reasonable pe
 riod of time. This talk covers three novel aspects of the OS: its incorpor
 ation of hardware memory virtualization\, its pure-Rust standard library\,
  and its message passing architecture.\n\nDesktop OSes such as Linux requi
 re a hardware MMU to virtualize memory. We explain how ARM has tricked us 
 into accepting that MMUs are hardware-intensive features only to be found 
 on more expensive “application” CPUs\, thus creating a vicious cycle where
  cheaper devices are forced to be less safe. Thanks to the open nature of 
 RISC-V\, we are able to break ARM’s yoke and incorporate well-established 
 MMU-based memory protection into embedded hardware\, giving us security-fi
 rst features such as process isolation and encrypted swap memory. In order
  to make Xous on real hardware more accessible\, we introduce the Baochip-
 1x\, an affordable\, mostly-open RTL 22nm SoC configured expressly for the
  purpose of running Xous. The Baochip-1x features a Vexriscv CPU running a
 t 400MHz\, 2MiB of SRAM\, 4MiB of nonvolatile RRAM\, and a quad-core RV32E
 -derivative I/O accelerator called the “BIO”\, based on the PicoRV clocked
  at 800MHz.\n\nMost Rust targets delegate crucial tasks such as memory all
 ocation\, networking\, and threading to the underlying operating system’s 
 C standard library. We want strong memory safety guarantees all the way do
 wn to the memory allocator and task scheduler\, so for Xous we implemented
  our standard library in pure Rust. Adhering to pure Rust also makes cross
 -compilation and cross-platform development a breeze\, since there are no 
 special compiler or linker concerns. We will show you how to raise the sta
 ndard for “Pure Rust” by implementing a custom libstd.\n\nXous combines th
 e power of page-based virtual memory and Rust’s strong borrow-checker sema
 ntics to create a safe and efficient method for asynchronous message passi
 ng between processes. This inter-process communication model allows for ea
 sy separation of different tasks while keeping the core kernel small. This
  process maps well onto the Rust "Borrow / Mutable Borrow / Move" concept 
 and treats object passing as an IPC primitive. We will demonstrate how thi
 s works natively and give examples of how to map common programming algori
 thms to shuttle data safely between processes\, as well as give examples o
 f how we implement features such as scheduling and synchronization primiti
 ve entirely in user space.\n\nWe conclude with a short demo of Xous runnin
 g on the Baochip-1x\, bringing Xous from the realm of emulation and FPGAs 
 into everyday-user accessible physical silicon.\n

DESCRIPTION:Join bleeptrack for a deep dive into the fascinating world of p
 rocedural generation beyond the screen. From stickers and paper lanterns t
 o PCBs\, furniture\, and even physical procedural generators\, this talk e
 xplores the challenges and creative possibilities of bringing generative p
 rojects into tangible form.\nIn this talk\, I will share practical insight
 s from developing procedural generation tools for physical objects: rangin
 g from stickers and paper lanterns to printed circuit boards and even furn
 iture. I will outline key challenges and considerations when generating de
 signs for fabrication tools such as laser cutters or pen plotters\, as wel
 l as how to adapt procedural systems so they can be reproduced by a wide a
 udience (not everyone has access to CNC machines or industrial equipment\,
  sadly!).\n\nBeyond technical considerations\, I aim to encourage attendee
 s to translate their own generative ideas into tangible artifacts and to f
 oster a culture of open-sourcing and knowledge sharing within the communit
 y.\n

DESCRIPTION:Auf der Insel Rügen und in Österreich tut sich was - und zwar n
 eue Chaos Events. Wir möchten über Anforderungen\, Herausforderungen\, Hür
 den\, Erfahrungen und Glücksmomente aus unserer Sicht der Orga erzählen. D
 as InselChaos fand im LaGrange e.V. im September 2025 statt und bildet den
  Auftakt für weitere kreative\, informative und chaotische Events auf der 
 Insel Rügen. Das Håck ma’s Castle wird mit etwas Humor auch über Herausfor
 derungen sprechen\, welche unter anderem durch dezentrale Teams aus divers
 en Hackspaces entstehen.\n**InselChaos**\nDer Port39 e.V. hatte den Traum\
 , das Chaos nach MV zu holen und ein größeres Event an der Ostsee zu veran
 stalten. Gerade erst 3 Jahre alt\, haben wir mit der Planung in kleinem Kr
 eis begonnen. Eine Location musste gesucht\, Inspirationen und Ideen gesam
 melt\, bürokratische Hürden und sehr viele individuelle Probleme gelöst we
 rden\, bis es Anfang September soweit war\, dass wir unsere Gäste begrüßen
  durften. In diesem Talk sprechen wir darüber\, wie es ist\, als kleiner V
 erein mit einem vierköpfigen Orga-Team ein ChaosEvent mit über 150 Gästen 
 zu koordinieren\, welche Schwierigkeiten wir dabei überwunden und vor alle
 m\, welche Learnings wir daraus gezogen haben\, um es nächstes Mal noch be
 sser zu machen.\n\n\n**Håck ma’s Castle**\nWir werden in unserem Talk\, da
 rüber sprechen\, welche Methoden und Meetingmodi wir ausgetestet haben\, g
 ute wie aber auch schlechte Entscheidungen welche getroffen wurden. Vorall
 em aber auch über die Herausforderung\, die es mit sich bringt\, wenn sich
  Wesen noch nicht kennen und wir zuerst auf menschlicher Ebene auch zusamm
 enkommen mussten\, damit es inhaltlich auch besser klappt.\n\nHard facts H

DESCRIPTION:Der Vortrag diskutiert Herausforderungen dezentraler Netzwerke 
 aus soziologischer Perspektive. Als dezentrale Netzwerke werden technische
  Infrastrukturen verstanden\, die nicht von einer zentralen Autorität\, so
 ndern verteilt über Instanzen zur Verfügung gestellt werden. Nutzer:innen 
 profitieren von dieser Infrastruktur\, nutzen beispielsweise das Fediverse
  oder das Tor-Netzwerk\, ohne zur Infrastruktur beizutragen. Zugleich könn
 en dezentrale Netzwerke nur dann bestehen\, wenn hinreichende Ressourcen v
 on Personen oder Organisationen mobilisiert werden\, um das Netzwerk überh
 aupt zur Verfügung zu stellen. Dies führt zur originären Instabilität deze
 ntraler Netzwerke\, wenn nicht der Weg der Kommodifizierung des Nutzer:inn
 enverhaltens eingeschlagen wird. Aufbauend auf dieser Zustandsbeschreibung
 \, werden Bedingungen erörtert\, um Kollektivgüter wie dezentrale Netzwerk
 e organisatorisch (und nicht technisch) herzustellen. Hierzu zählen Partiz
 ipation oder die Idee einer öffentlichen Grundfinanzierung. Der Vortrag wi
 rd neben soziologischen Ideen und harten Zahlen auch durch eine ordentlich
 e Portion Idealismus zu Fragen der Souveränität und Autonomität in der Dig
 italisierung motiviert.\nDie Soziologie hat immer etwas mitzuteilen\, soba
 ld Fragen kollektiven Handelns auftreten. Dies gilt sowohl für soziale wie
  auch digitale Räume. So hat der Soziologe Peter Kollock bereits in den 19
 90er Jahren festgestellt\, „the Internet is filled with junk and jerks“ (K
 ollock\, 1999\, S. 220). Gegenwärtig dürfte die Mehrheit dieser Aussage an
 standslos zustimmen. Aber dies ist nicht der entscheidende Punkt\, sondern
  die weitere Beobachtung: „Given that online interaction is relatively ano
 nymous\, that there is no central authority\, and that it is difficult or 
 impossible to impose monetary or physical sanctions on someone\, it is str
 iking that the Internet is not literally a war of all against all” (1999\,
  S. 220).\n\nDie Welt kennt inzwischen zahlreiche Gegenbeispiele\, bei den
 en Autoritäten das Internet nutzen\, um das Nutzungsverhalten zu monetaris
 ieren oder Überwachungstechnologien zur Sanktionierung einsetzen (Zuboff\,
  2019). Diese Ausgangslage beziehe ich in meiner Forschung ein\, wenn ich 
 dezentrale Netzwerke wie das Fediverse oder das Tor-Netzwerk aus soziologi
 scher Perspektive betrachte. In erster Linie bin ich daran interessiert zu
  verstehen\, wie dezentrale Netzwerke – organisatorisch nicht technisch – 
 entstehen und welche Herausforderungen es dabei zu überwinden gilt (Sander
 s & Van Dijck\, 2025). Eine zentrale Motivation orientiert sich an der Fra
 ge\, wie ein Internet ohne zentrale Autorität\, verringert von Marktabhäng
 igkeiten\, resilient gegenüber Sanktionsmechanismen und Souverän bezüglich
  eigener Daten\, aufgebaut werden kann. Motiviert durch diesen präskriptiv
 en Rahmen\, betrachte ich im Vortrag die Herausforderungen zunächst deskri
 ptiv und beziehe meine soziologische Perspektive ein. Denn in der Regel pr
 ofitieren Menschen\, die einen Vorteil aus der Realisierung eines bestimmt
 en Ziels ziehen\, unabhängig davon\, ob sie persönlich einen Anteil der Ko
 operation tragen – oder eben nicht. Das kollektive Handeln fällt mitunter 
 schwer\, obwohl oder gerade\, weil ein begründetes kollektives Interesse z
 ur Umsetzung eines bestimmten Zieles besteht. Gleiche Interessen sind nich
 t gleichbedeutend mit gemeinsamen Interessen. Diese Situationsbeschreibung
  ist vielfältig anwendbar von WG-Aufräumplänen bis zu Fragen der klimaneut
 ralen Transformation. Der Grund ist\, dass kollektives Handeln ein Mindest
 maß an Zeit\, Aufwand oder Geld verursacht\, sodass vielfach ein Trittbret
 tfahren gewählt wird in der Hoffnung\, dass immer noch genug andere kooper
 ieren\, um das gewünschte Ziel zu erreichen (Hardin\, 1982).\n\nAus dieser
  Perspektive betrachte ich dezentrale Netzwerke. So kann das Fediverse ode
 r der Tor-Browser genutzt werden\, ohne eine eigene Instanz oder Knoten zu
  hosten. Dies ist auch nicht das Ziel der genannten dezentralen Netzwerke.
  Dennoch: Die Kosten und der Aufwand für die technische Infrastruktur müss
 en von einem kleinen Teil getragen werden\, während die überwältigende Meh
 rheit der Nutzer:innen von der Infrastruktur profitieren\, ohne einen Beit
 rag zu dieser zu leisten. Dies führt zur originären Instabilität dezentral
 er Netzwerke und stellt eine relevante Herausforderung für die Zukunft dar
 . Während durch Netzwerkanalysen das Wachstum und die Verstetigung von dez
 entralen Netzwerken beschrieben wird\, fehlt es an einem vertieften Verstä
 ndnis über Bedingungen wie dezentrale Netzwerke überhaupt entstehen. Währe
 nd des Vortrags werde ich empirische Daten zur Entwicklung des Fediverse u
 nd des Tor-Netzwerkes zeigen\, um die Herausforderung zu verdeutlichen. In
 sbesondere das Tor-Netzwerk steht dabei vor dem Problem\, dass die Möglich
 keit zur De-Anonymisierung steigt\, wenn die Anzahl an Knoten sinkt. Die Ü
 berwindung des von mir dargestellten Kollektivgutproblems nimmt demnach ei
 ne zentrale Rolle zur Aufrechterhaltung ein.\n\nDie Motivation sich mit de
 zentralen Netzwerken auseinanderzusetzen\, resultiert aus der Umkehr der A
 rgumentation\, wenn Netzwerke über eine zentrale Autorität verfügen und zu
 gleich in der Lage sind\, Sanktionsmechanismen zu nutzen\, beispielsweise 
 um unliebsame User:innen zu sperren\, das Nutzungsverhalten zu überwachen 
 und zu monetarisieren (Zuboff\, 2019). Hierbei beziehe ich mich offensicht
 lich auf die Entwicklung sozialer Medien\, die das oben beschriebene Probl
 em kollektiven Handelns durch Kommodifizierung der Infrastruktur lösen. Äh
 nliches ist aus dem Bereich der Kryptowährung bekannt\, welche ebenfalls d
 urch den individualisierten monetären Vorteil\, das heißt der Verheißung e
 iner Kapitalakkumulation\, Kooperationsprobleme überwindet. Stellen wir un
 s so die Zukunft des Internets vor?\nDezentrale Netzwerke sind nicht per s
 e eine allumfassende technische Lösung für gesellschaftlich-soziale Proble
 me. Im Gegenteil: Dezentrale Netzwerke\, wenn sie nicht auf Kommodifizieru
 ng basieren\, unterliegen einer sozialen Ordnung\, die sich eben nicht tec
 hnisch lösen lässt. Ein Bewusstsein über die Notwendigkeit dezentraler Net
 zwerke ist hierbei leider nicht ausreichend\, sondern es braucht Menschen 
 und Organisationen\, die bereit sind einen Teil der Infrastruktur zu trage
 n\, ohne einen direkten Vorteil hiervon zu erhalten. Diese Selbstorganisat
 ion steht im Vergleich zu profitorientierten Unternehmen immer im Nachteil
  (Offe & Wiesenthal\, 1980).\n\nIn meiner Forschung verbinde ich mein Inte
 resse an Grundstrukturen und Bedingungen sozialer Ordnung\, wie dem Kooper
 ationsproblem\, mit dem Anspruch gesellschaftlicher Gestaltung. Allein das
  Bewusstsein über diese Bedingungen kann noch kein Kooperationsproblem lös
 en. Es kann allerdings helfen\, den Rahmen dieser Bedingungen aktiv zu ges
 talten. Ich werde mich dabei zwischen kritischen Realitäten und hoffnungsv
 ollen Ausblicken bewegen\, denn ganz offensichtlich existieren dezentrale 
 Netzwerke\, die eine organisatorische und technische Alternative anbieten.

DESCRIPTION:HostileShop is a python-based tool for generating prompt inject
 ions and jailbreaks against LLM agents. I created HostileShop to see if I 
 could use LLMs to write a framework that generates prompt injections again
 st LLMs\, by having LLMs attack other LLMs. It's LLMs all the way down. Ho
 stileShop generated prompt injections for a winning submission in OpenAI's
  GPT-OSS-20B RedTeam Contest. Since then\, I have expanded HostileShop to 
 generate injections for the entire LLM frontier\, as well as to mutate jai
 lbreaks to bypass prompt filters\, adapt to LLM updates\, and to give advi
 ce on performing injections against other agent systems. In this talk\, I 
 will give you an overview of LLM Agent hacking. I will cover LLM context w
 indow formats\, LLM agents\, agent vulnerability surface\, and the prompti
 ng and efficiency insights that led to the success of HostileShop.\n[Hosti
 leShop](https://github.com/mikeperry-tor/HostileShop) creates a simulated 
 web shopping environment where an **attacker agent LLM** attempts to manip
 ulate a **target shopping agent LLM** into performing unauthorized actions
 . Crucially\, HostileShop does not use an LLM to judge attack success. Ins
 tead\, success is determined automatically and immediately by the framewor
 k\, which reduces costs and enables rapid continual learning by the attack
 er LLM.\n\nHostileShop is best at discovering **prompt injections** that i
 nduce LLM Agents to make improper "tool calls". In other words\, HostileSh
 op finds the magic spells that make LLM Agents call functions that they ha
 ve available to them\, often with the specific input of your choice.\n\nHo
 stileShop is also capable of [enhancement and mutation of "universal" jail
 breaks](https://github.com/mikeperry-tor/HostileShop?tab=readme-ov-file#pr
 ompts-for-jailbreakers). This allows **cross-LLM adaptation of universal j
 ailbreaks** that are powerful enough to make the target LLM become fully u
 nder your control\, for arbitrary actions. This also enables public jailbr
 eaks that have been partially blocked to work again\, until they are more 
 comprehensively addressed.\n\nI created HostileShop as an experiment\, but
  continue to maintain it to let me know if/when LLM agents finally become 
 secure enough for use in privacy preserving systems\, without the need to 
 rely on [oppressive](https://runtheprompts.com/resources/chatgpt-info/chat

DESCRIPTION:While FPGA developers usually try to minimize the power consump
 tion of their designs\, we approached the problem from the opposite perspe
 ctive: what is the maximum power consumption that can be achieved or waste
 d on an FPGA? Short answer: we found that it’s easy to implement oscillato
 rs running at 6 GHz that can theoretically dissipate around 20 kW on a lar
 ge cloud FPGA when driving the signal to all the available resources. It i
 s interesting to note that this power density is not very far away from th
 at of the surface of the sun. However\, such power load jump is usually no
 t a problem as it will trigger some protection circuitry. This led us to t
 he next question: would a localized hotspot with such power density damage
  the chip if we remain within the typical power envelope of a cloud FPGA (
 ~100 W)? While we could not “fry” the chip or induce permanent errors (and
  we tried several variants)\, we did observe that a few routing wires aged
  to become up to 70% slower in just a few days of stressing the chip. This
  basically means that such an FPGA cannot be rented out to cloud users wit
 hout risking timing violations.\nIn this talk\, we will present how we opt
 imized power wasting\, how we measured wire latencies with ps accuracy\, h
 ow we attacked 100 FPGA cloud instances and how we can protect FPGAs again
 st such DOS attacks.\nFPGA instances are now offered by multiple cloud ser
 vice providers (including Amazon EC2 F1/F2 instances\, Alibaba ECS Instanc
 es\, and Microsoft Azure NP-Series). The low-level programmability of FPGA
 s allows implementing new attack vectors including DOS attacks. While some
  severe attacks (such as short circuits) cannot be easily deployed as user
 s are prevented to load own configuration bitstreams on the cloud FPGAs\, 
 it has been demonstrated that it is possible to leak information (like clo
 ud instance scheduling policies or the physical topologies of the FPGA ser
 vers) or to mount DoS attacks by excessive power hammering. For instance\,
  basically all cloud FPGAs provide logic cells that can be configured as s
 mall shift registers. This allows building toggle-shift-registers with 10K
  and more flip-flops\, which can draw over 1 KW power when clocked at a fe
 w hundred MHz. \nIn our work\, we created fast ring-oscillators that bypas
 s all design checks applied during bitstream cloud deployment and how we a
 chieved toggle rates of 8 GHz inside an FPGA by using glitch amplification
 . The latter one was calibrated with the help of a time-to-digital convert
 er (TDC).\nAs a first attack\, we used power hammering to crash AWS F1 ins
 tances by increasing power consumption to 300 W (three times the allowed p
 ower envelope). We used physical unclonable functions (PUFs) to examine th
 e behaviour of the attacked FPGA cloud instances and we found that most re
 mained unavailable for several hours after the attack.\nAs a more subtle a
 ttack\, we tried to cause permanent damage to FPGAs in our lab by driving 
 fast toggling signals to virtually any available wire (and primitive) into
  a small region of the chip. With this\, we created hotspot designs that d
 raw 130 W in less than 1% of the available logic and routing resources of 
 a datacenter FPGA. Even though the achieved power density was excessive\, 
 it was insufficient to induce permanent damages. This is largely due to th
 e area inefficiencies of an FPGA that limit the power density. For instanc
 e\, FPGAs use large multiplexers to implement the switchable connections a
 nd there exists only one active path that is routed through the multiplexe
 rs\, hence\, leaving most of the transistors sitting idle. Similarly\, FPG
 As provide a large number of configuration memory cells (about 1 Gb on a t
 ypical datacenter device) that draw negligible power as these do not switc
 h during operation. All these idle elements force the power drawing circui
 ts to be spread out\, hence limiting power density. Anyway\, when experime
 nting with different hotspot variants\, we found thermal runaway effects a
 nd excessive device aging with up to a 70% increase in delay on some wires
 . We achieved this aging in just a few days and under normal operational c
 onditions (i.e. by staying within the available power budget and having bo

 o render an FPGA useless as it will usually not be fast enough to host (re
 alistic) user designs.\nBeyond exploring these attack vectors\, we develop
 ed countermeasures and design guidelines to prevent such attacks. These in
 clude scans of the user designs\, use restrictions to resources like IOs a
 nd clock trees\, as well as runtime monitoring and FPGA health checks. Wit
 h this\, we believe that FPGAs can be operated securely and reliably in a 
 cloud setting.\n

DESCRIPTION:The USA is demanding from all 43 countries in the "Visa Waiver 
 Programme" (VWP)\, which enables visa-free travel\, to conclude an "Enhanc
 ed Border Security Partnership" (EBSP). This is intended to grant US autho
 rities direct access to police databases in these - mostly European - coun
 tries containing fingerprints\, facial images and other personal data. Any
 one who refuses this forced "border partnership" faces exclusion from the 
 visa-free travel programme.\nThe US demand is unprecedented: even EU membe
 r states do not grant each other such extensive direct database access – n
 ormally the exchange takes place via the "hit/no-hit principle" with a sub
 sequent request for further data. This is how it works\, for example\, in 
 the Prüm Treaty among all Schengen states\, which has so far covered finge
 rprints and DNA data and is now also being extended to facial images.\n\nT
 he EBSP could practically affect anyone who falls under the jurisdiction o
 f border authorities: from passport controls to deportation proceedings. U
 nder the US autocrat Donald Trump\, this is a particular problem\, as his 
 militia-like immigration authority ICE is already using data from various 
 sources to brutally persecute migrants – direct access to police data from
  VWP partners could massively strengthen this surveillance apparatus. Germ
 any alone might give access to facial images of 5.5 million people and fin
 gerprints of a similar dimension.\n\nThe USA has already tightened the Vis
 a Waiver Programme several times\, for instance in 2006 through the introd
 uction of biometric passports and in 2008 through the ESTA pre-registratio
 n requirement. In addition\, there were bilateral agreements for the excha
 nge of fingerprints and DNA profiles – however\, these may only be transmi
 tted in individual cases involving serious crime.\n\nExisting treaties suc
 h as the EU-US Police Framework Agreement are not applicable to the "Enhan
 ced Border Security Partnership"\, as it applies exclusively to law enforc
 ement purposes. It is also questionable how the planned data transfer is s
 upposed to be compatible with the strict data protection rules of the GDPR
 . The EU Commission therefore wants to negotiate a framework agreement on 
 the EBSP that would apply to all member states. Time is running short: the
  US government has set VWP states a deadline of 31 December 2026. Some alr
 eady agreed on a bilateral level.\n

DESCRIPTION:Zwischen offenen Briefen\, Massenmails\, Petitionen und Kaffee

 ählen\, wie politische Einflussnahme wirklich funktioniert. Ein ehrlicher 
 Blick hinter die Kulissen parlamentarischer Entscheidungsfindung – mit pra
 ktischen Tipps\, wie die Zivilgesellschaft ihre Energie dort einsetzt\, wo
  sie wirklich Wirkung entfaltet.\nZiel des Talks ist es\, ein realistische
 s Bild davon zu vermitteln\, wie parlamentarische Entscheidungsfindung fun
 ktioniert – und praktische Hinweise zu geben\, wie man Einfluss nehmen kan
 n\, ohne dabei Ressourcen zu verschwenden.\n\nWie bringt man politische Pr
 ozesse in Bewegung? Was passiert eigentlich mit einer Mail\, wenn sie an e
 inen Abgeordneten geht? Und wie unterscheidet sich konstruktive Interessen
 vertretung von übergriffigem Lobbyismus?\n\nIn diesem Talk berichten Anna 
 Kassautzki (Mitglied des Bundestags von 2021 bis 2025\, stellvertretende V
 orsitzende des Digitalausschusses 20. LP) und Rahel Becker (ehemalige wiss
 enschaftliche Mitarbeiterin Digitales) aus der Innenperspektive parlamenta
 rischer Arbeit.\n\nChatkontrolle\, Data Act\, Recht auf Open Data\, DSGVO\
 , es gab viel zu verhandeln in der letzten Legislaturperiode. Anna und Rah
 el waren mittendrin und geben einen Einblick in die hektische -  teils abs
 urde Kommunikation mit Interessenvertretungen. Dabei liegt der Fokus immer
  auf der Frage: Welche Strategien braucht es\, damit zivilgesellschaftlich
 e Arbeit nicht verpufft?\n\nZugleich geht es um die strukturellen Fragen:\
 nWo sind die Flaschenhälse für politischen Fortschritt? Wie priorisieren A
 bgeordnete in einem überfüllten Kalender? Und welche Hebel kann die (digit
 ale) Zivilgesellschaft sinnvoll nutzen\, um Gehör zu finden?\n\nDenn gerad
 e in Zeiten massiver digitalpolitischer Herausforderungen ist informierte\
 , strategische Beteiligung notwendiger denn je. Ein Vortrag für alle\, die
  sich in politische Prozesse einmischen wollen.\n

 brates trying\, failing and the beauty of discovering hidden Talents toget
 her when the most beautiful cuties from the audience enter the stage to tr
 y something they have absolutely no experience in.\nThe show is an open fo

 themselves vulnerable. We bring a queer format that celebrates people for 
 simply being humans to Hamburgs neighborhood pubs\, autonomous stages and 
 other easily accessible spaces. In doing so it's explicitly anti-capitalis
 t\, builds communities and unlikely alliances.\nNot just in the hacker/CCC
  community we applaud the cool things people can do: The big stage is ofte
 n reserved for outstanding achievements\; attention and social credits usu
 ally go to those who already have the network and skills. While we conside
 r celebrating success to be absolutely necessary\, we see the need to give
  people space to try things out\, to fail publicly without having to be as
 hamed\, and to celebrate Imperfection. Stage presence comes from trying on
  stage\, and the Maybe Talent Show is the place where this is possible for
  everyone. Inclusive\, hilarious and without making fun of anyone. Promise

DESCRIPTION:\n[To secure spot on this workshop please sign in here.](https:
 //dud-poll.inf.tu-dresden.de/kimchi_39c3/) - max 25\n\n[Workshop manual is
  shared here.](https://foodhackingbase.org/wiki/Recipe:Traditional_Kimchi_
 making_manual)\n\nThis is hands on workshop where your learn how to prepar
 e Korean 김치 (kimchi). You will do at least two types of kimchies based on 
 wild/spontaneous fermentation. We will see what type of nice vegetables we
  will get. Highly likely we will do cabbage kimchi (배추 김치) and then either
  radish\, topinambur or turnip kimchi.\n\nThe preparation of vegetable fer
 ments in Korea\, called “kimchies”\, is an ancient fermentation skill base
 d on spontaneous fermentation (naturally occurring lactic acid producing b
 acteria among the others) and variety of ingredients added. This workshop 
 is a hands-on experience that reviews the basics of Korean kimchi making a
 nd today's preparation styles. We will go through the main topics which ar
 e salt to vegetables and liquid ratio and when to apply it and how. This o
 ne is crucial. We will explain the importance of the effect of ginger\, ga
 rlic and spicy pepper and their roles in preventing unwanted microbial dev
 elopment. Part of this workshop is tasting of kimchi samples so you get id
 ea what should your results taste like. You will be leaving with jar of ki
 mchi and knowledge how to make your own.\n\nThis workshop is based on "don
 ation at your will no one turned away for lack of funds". Part of the work
 shop benefits goes towards fhb budget and hopefully larger part towards Al
 goldor's pocket to cover participation costs at 39c3 event and if some ext
 ras are accumulated\, then towards current and future fermentation project
 s.\n

 gs with suicidal thoughts? How do we protect ourselves from burnout? What 
 good resources do we already know and can share with each other? Which res
 sources are still missing? Together\, we will exchange ideas in small grou

DESCRIPTION:Im Jahr 2026 findet in Berlin die nächste Wahl zum Abgeordneten
 haus statt.\n\nWie stehen die dort antretenden Parteien zu Digital-Themen?
  Und wie lässt sich die Übereinstimmung mit eigenen Überzeugungen "berechn
 en"? Wie geht eins mit faschistischen Parteien um und welche anderen Detai
 ls gilt es zu beachten?\n\nDer kleindatenverein.org hat bereits mehrere Di
 gital-O-maten gebaut und wird auch zur Berliner Wahl 2026 einen anbieten. 
 Nach einer Vorstellung möglicher Arten von Wahl-O-Maten\, wollen wir uns f
 ür ein Modell entscheiden\, die nächsten Schritte festlegen und idealerwei
 se den ersten Code einschecken.\n\nWer mitmachen oder auch einfach nur mal
  reinschnuppern will\, ist herzlich willkommen. Keine Vorkenntnisse nötig.
 \n\nLeute aus anderen Bundesländern\, in denen 2026 gewählt wird und die I
 nteresse am Bau eines Digital-O-Maten haben\, sind besonders willkommen.\n

DESCRIPTION:Learn Arduino using TV-B-Gone as an example project. You've pro
 bably heard lots about Arduino. But if you don't know what it is\, or how 
 you can use it to do all sorts of cool things\, then this fun and easy wor
 kshop is for you. As an example project\, we'll be creating a TV-B-Gone re
 mote control out of an Arduino you can take home with you.\n**[Arduino](ht
 tp://arduino.cc/)** is an amazingly powerful tool that is very simple to l
 earn to use. It was designed so that artists and non-geeks can start from 
 nothing\, and make something cool happen in less than 90 minutes. Yet\, it
  is powerful enough so that experienced expert geeks can use it for their 
 projects as well.\n\nThis workshop is easy enough for _**total newbies**_ 
 to **learn all you need to know to get going on an Arduino.**\n\nParticipa
 nts will make their own Arduino clone\, and set it up on solderless breadb
 oards to make their own [TV-B-Gone](http://www.tvbgone.com) remote control
  to turn off TVs in public places -- a fun way to learn Arduino (and elect
 ronics) basics.\n\n**Materials costs**:  \nThe workshop is free\, but if y

 thing before in their lives. It is actually a very easy skill to learn. It
  is also very useful.\n* Then we will each make our own Arduino clone from
  a kit.\n* Now that we each have our own Arduino board\, we will set up th
 e free and open-source *Arduino software* on our laptops (if you bring one
 ) -- Windows\, Linux\, and MacOS are all fine!\n* And then its time to mak

 ## Session\n\nLarge Language Models (LLMs) have taken the world by storm. 
 Alongside their vast potential\, these models also present unique security
  challenges. This session will serve as a primer on LLM security and secur
 e LLMOps\, introducing key issues and concepts related to the security of 
 LLMs and systems relying on them. For example\, we will be looking at issu
 es such as prompt injection\, sensitive information disclosure\, and issue
 s related to the interaction of LLMs with the “outside world” (e.g.\, plug
 ins or APIs\, RAG\, Agentic AI). Of course\, we are also going to briefly 
 look at how to red-team LLMs.\n\nThis session is based on previous iterati
 ons of “A Primer on LLM Security” at Congress and\, based on audience feed
 back\, has been extended and developed further.\n\n\nThis session is based
  on previous iterations of “A Primer on LLM Security” at Congress and\, ba
 sed on audience feedback\, has been extended and developed further.\n\n## 
 Target Audience and Required Previous Knowledge\n\nThis session targets be
 ginners and does not assume (in-depth) knowledge about LLMs. If you have p
 rior experience in LLM security and anticipate insights into the latest de
 velopments\, this session most likely is not for you.\nPlease note that th
 is session will not be about using LLMs in offensive or defensive cybersec
 urity.\n\n## Learning Objectives\n\nFrom a learning perspective\, after th
 e session\, participants will be able to …\n\n* describe what LLMs are and
  how they fundamentally function.\n* describe LLMOps and outline fundament
 al principles of secure LLMOps.\n* describe common security issues related
  to LLMs and systems relying on LLMs.\n* describe what LLM red teaming is.
 \n* perform some basic attacks against LLMs to test them for common issues
 .\n\n## About Me\n\nMy Name is Ingo\, and I am currently responsible for D
 igital Education and Educational Technology at the University of Cologne. 
 Relevant to this session\, I have a background in computational linguistic
 s and have been working with LLMs for quite some time – also prior to the 
 ChatGPT moment. I am also involved in developing and providing AI infrastr
 ucture at scale. Of course\, all of this is embedded within a deep interes
 t in cyber- and information security.\n\n## Format\nThe session will be sp
 lit into a 45-minute talk as well as 15 minutes of discussion. Participant
 s will be provided with the slides as well as some resources for further s
 tudy.\n\n## Technical Requirements\nAs this will not be a highly hands-on 
 session\, there are no technical requirements. If you want to experiment w
 ith some of the topics\, a device capable of accessing and/or running LLMs
  is necessary. If you want to “go deeper\,” you will need a device – e.g.\
 , a laptop\, capable of running LLMs locally.\n\n## Material\n\nAfter the 
 session\, I will provide all materials\, including some selected additiona
 l resources. All materials will also be provided via this page.\n\n[Slides
  (PDF) via Slideshare](https://de.slideshare.net/secret/1UNWblpgKTSoSR)\n\

 ous iterations of Congress.\n

DESCRIPTION:\nWe've been working on Teamtype (previously known as Ethersync
 ) for two years now: It connects directories on different computers togeth
 er\, and keeps them in sync. And if you open a file in your text editor\, 
 you can edit it together\, and see each other's cursors.\n\nThis enables a
  new form of smooth real-time collaboration. You can use it for pair progr
 amming or note-taking\, for example\, all from the comfort of your own edi
 tor! It feels a bit like the missing real-time complement to Git.\n\nTeamt
 ype follows local-first principles\, and uses encrypted peer-to-peer conne
 ctions (you don't need a server or an account). You can also work on entir
 e projects\, not just single files.\n\nAt 39C3\, it's time for a live demo
 ! Let me show you how Teamtype works and what you can do with it! We're ma
 intaining plugins for Neovim and VS Code/Codium\; others are working on pl
 ugins for Jetbrains IDEs\, have integrated it into TeXstudio\, or are buil
 ding a web editor for it! I can also show you some more experimental featu
 res like a Hedgedoc bridge\, or writing commit messages together.\n\nWe'd 
 be excited for more collaboration on collaboration\, so let me show you ho
 w to get involved!\n\nIn the final part of this session\, you can install 
 & try Teamtype for yourself in a frantic massively-multiplayer editing exp
 eriment! :D\n\n- Source code: <https://github.com/teamtype/teamtype>\n- Do

DESCRIPTION:\nFusion is always 30 years in the future because government pr
 ojects are too big\, too expensive\, and too slow. It doesn't have to be t
 his way.\n\nThere are better approaches than the three known research dire
 ctions. There are better fusion fuels that don't cause radioactive contami
 nation. Fusion has even been achieved by school classes and private indivi
 duals. A proof that it is possible with much less effort.\n\nIf we investe
 d as much money in proton-boron fusion as we do in deuterium-tritium\, we 
 would probably have power plants in 15 years. Dense Plasma Focus is suitab
 le for decentralized 10-MW power plants. Inertial Electrostatic Confinemen
 t for neighborhood power plants with 100 MW. This is not about cold fusion
 . It's about fusing atomic nuclei with high energy (hot) to gain even more
  energy. But in different physical configurations. Unfortunately\, the med
 ia ignores these other hot fusion approaches.\n\nThis is an info dump on t
 he state of the art: what fusion fuels exist\, how you build your own fusi
 on reactor\, why hot plasma is physically unfavorable\, why some people wa
 nt to strip-mine the moon\, and why other fusion projects that must make d
 o with 100 times less money still achieve similar performance. These proje
 cts don't appear in the mainstream press. But they will soon overtake ITER
 .\n\n\nIf we want to achieve the energy transition\, then policymakers mus
 t stop investing in supposedly safe large-scale technology. It could be mu
 ch faster and cheaper and the new energy grid could be decentralized.\n

DESCRIPTION:\nIn Science Fiction gibt es Überlichtgeschwindigkeit\, Aliens\
 , Antigravitation\, Terraforming\, Schutzschilde\, Beamen\, Railguns\, KI\
 , Fusion\, Nano\, und noch viel mehr.\n\nDieser Vortrag gibt einen Überbli
 ck\, was die moderne Wissenschaft dazu sagt. Der Stand der Wissenschaft en
 twickelt sich weiter und das kommt nur langsam in der Science Fiction Lite
 ratur und in der Öffentlichkeit an. Was stimmt noch und was hat sich geänd
 ert? Was ist wissenschaftlich fundiert\, was wäre vielleicht doch möglich 
 und was wird immer erfundene Wissenschaft bleiben.\n\nEin realistischer Bl
 ick auf die Technologien von Star Trek und Star Wars. Außerdem ein Blick ü
 ber den Tellerrand\, denn auch in der Vergangenheit wurden ab und zu schon
  Technologien erfunden\, die sich vorher niemand vorstellen konnte.\n

DESCRIPTION:\nData literacy and digitalisation are crucial topics in today'
 s research institutions\, to tackle global challenges like climate change\
 , the dramatic loss of species and the erosion of democracy. Nevertheless\
 , most research data is not digitalised nor back-uped\; reproducible & tra
 nsparent research is often a dream.\nIn Research Data Management\, a lot o
 f guidlines exist to face these difficulties: Data Management Plans\, FAIR
  data\, ELSA\, etc. It seems like there is a strategy and buzzword for eve
 ry problem.\n\n**But what is missing is a discussion\, if these strategies
  are inclusive (for neurodivergent people).** How can we alter them\, what
  is needed for you to apply them?\n\nNo matter if you are a researcher\, w
 ho has to apply all those strategies\, a Data Steward teaching them\, or j
 ust interested in the topic: I would love to **discuss** with you about yo
 ur experiences in digitalisation in research institutions & universities a
 nd hear about your experiences to raise awareness in the research data com
 munity.\n\nAbout the speaker Sarah Büker:\nWhile working as a Data Scienti
 st at the Data Science Center (BMFTR founded Data Nord Project @ Universit
 y of Bremen) and beeing neurodivergent myself\, I have faced a lot of excl
 usive strategies and would love to change the current situation.\n

DESCRIPTION:\nThe hearing aid space is antiquated and overpriced and badly 
 in need of a widely available and easy to use open source alternative. 5 m
 anufacturers control 99% of the global market\, and have little incentive 
 to innovate or compete on prices\, so hearing aids cost thousands of Euros
 . Everyone we meet has either themselves or through a loved one had a bad 
 experience with hearing aids\, or experienced quality of life issues with 
 hearing loss.\n\nWe've been working on making an alternative with our know
 ledge of professional audio technology\, which has long outpaced the medic
 al hearing aid realm. We want to both share the journey\, and learn about 
 your experiences both with the technology and hearing itself.\n

 set up a portable shortwave station and get a crash course in shortwave op
 eration. Then it's time to get on the air! Other radio amateurs around the
  world are waiting to contact us. Can you manage the 10 radio connections 
 necessary for a successful "activation" of the park?\n\nNOTE: We meet AT T
 HE CHAOSWELLE ASSEMBLY and start there with a short introduction to the PO
 TA program. Then we go out into the park together. Dress warmly and weathe
 rproof! We go outside even when it's raining or snowing!\n\nIf anyone want

DESCRIPTION:Introduction to Parks on the Air (POTA). POTA is an internation
 al radiosport award program that encourages licensed amateur radio operato
 rs to visit\, enjoy and operate portable equipment in a variety of parks a
 nd public lands. Due to popular demand\, now also available at a later tim
 e!\nDue to popular demand\, now also available at a later time!\n\nPOTA in
 troduction "in a nutshell" followed by joint POTA activation on shortwave 
 in the "Planten un Blomen" park right next to the CCH.\n\nWe meet daily at
  01:00 p.m. at the Assembly for a short introduction and then go out into 
 the park together. The participants learn how to set up a portable shortwa
 ve station and get a crash course in shortwave operation. Then it's time t
 o get on the air! Other radio amateurs around the world are waiting to con
 tact us. Can you manage the 10 radio connections necessary for a successfu
 l "activation" of the park?\n\nNOTE: We meet AT THE CHAOSWELLE ASSEMBLY an
 d start there with a short introduction to the POTA program. Then we go ou
 t into the park together. Dress warmly and weatherproof! We go outside eve
 n when it's raining or snowing!\n\nIf anyone wants to join us later: radio
  amateurs can reach us in the park on 145.500 MHz FM.\n\nOur location in t

 knowledge and experience in technology\, we are obliged to share it with p
 eople who don’t have such competencies. Strengthening non-tech communities
  is essential for our collective well-being. What is the minimum level of 
 tech education that everyone engaged in class struggle should acquire? Do 
 we have the tools to protect non-tech people in our environment beyond the
  hackerspaces communities? How to build horizontal safe-spaces\, secure in
 frastructures to educate others and which tools and techniques are the mos
 t effective for education?\n\nLet's have a discussion and create ready to

 printing technique and how to create the printing plates.\nWe print using 
 the primary colors and can mix any other color as needed.\nWhat makes Lego
  Dots™ exciting is that you are bound to a grid – in this case\, 8×8 units
 . The tiles come in different shapes: circles\, squares\, quarter circles\
 , and many more. Have a look at the gallery to see some examples.\nWe prin
 t using a press from the Open Press Project.\nThe print size is limited to
  7×7 cm due to the press we are using.\nIt is a “jump-in” workshop with no

DESCRIPTION:\nAt several Chaos events\, you can often spot a cheerful group
  of people playing the game “Joustmania” ( https://github.com/adangert/Jou
 stMania ).\n\nIn this game\, each player holds a PlayStation Move controll
 er that tracks the player’s movement.\nAs soon as a controller accelerates
  too quickly\, the player is eliminated from the game.\nThe competitors th
 erefore try to defeat each other by bumping or nudging the other players’ 
 controllers\, forcing them to move too fast.\n\nThis year\, I decided to r
 ebuild the game myself and ran into quite a few obstacles along the way: f
 rom sourcing the hardware\, to setting up a Raspberry Pi (the game is alre
 ady about 10 years old)\, all the way to compiling Bluetooth drivers. In t
 he end\, this even resulted in my own fork of the project: https://github.
 com/VanFanelia/joustmania-remastered\n\nIn this session\, I would like to 
 share what I’ve learned\, answer your questions about the game or rebuildi
 ng it\, and/or organize a few rounds of play.\n

DESCRIPTION:\nConventional computer algorithms are superior to the human in
 tellect in many regards: for instance at multiplying large numbers or winn
 ing at chess by analyzing huge numbers of moves. But there are also many t
 asks which come naturally to us yet exceed the capabilities of algorithms 
 by vast amounts: Rigid algorithms can't decipher human handwriting or driv
 e cars.\n\nThe recent breakthroughs in artificial intelligence circumvent 
 these barriers by employing quite a different approach: They use artificia
 l neural networks\, which are inspired by the partially-understood way the
  human brain works.\n\nThe unique feature of artificial neural nets is tha
 t they aren't rigid\, but can learn. Human programmers specify their rough
  structure and supply training data\, but don't write a single line of cod
 e governing their behavior.\n\n**In the spirit of a good Unix command-line
  tool\, this talk aspires to explain one thing and explain it well: How do
  artificial neural nets accomplish the feat of learning?**\n\nWe'll learn 
 that the answer is related to a mathematical breakthrough made at the end 
 of the 17th century and discuss why deep learning only surged in the last 
 few years\, even though the basics of artificial neural nets were already 
 understood in the 1980s. We'll also touch upon some of the greatest proble
 ms of neural nets\, which emerge directly from the way neural nets learn.\
 n\nThe talk doesn't require any advanced knowledge of mathematics. If you'
 re already familiar with Michael Nielsen's book\, then don't expect to lea
 rn anything new and come to this talk only if you want to contribute inter
 esting remarks. The talk has the goal of making the other neural network t
 alks more accessible.\n\n**[Transcript](https://chaos.quasicoherent.io/)**

DESCRIPTION:\nMyonen-Detektion mit einer Funkenkammer. Wie funktioniert das
  eigentlich?\n\nMyonen sind Teilchen\, die Elektronen sehr ähnlich sind\, 
 nur deutlich schwerer. Sie entstehen in der kosmischen Hintergrundstrahlun
 g und treffen ständig auf die Erde. Eine praktische Eigenschaft dieser Tei
 lchen ist\, dass sie beim Durchqueren von Materie\, Moleküle ionisieren. A
 uf ihrem Weg hinterlassen sie also Spuren aus freien Elektronen.\n\nIn ein
 er Funkenkammer macht man sich genau diesen Effekt zunutze: Zwischen zwei 
 Elektroden liegt ein starkes elektrisches Feld an. Wenn ein vorbeifliegend
 es Myon ein Gas ionisiert\, werden die frei gewordenen Elektronen im Feld 
 beschleunigt und lösen einen sichtbaren Funken aus. So wird die unsichtbar
 e Spur des Myons kurzzeitig sichtbar.\n\nWie kann man wissen\, ob das dete
 ktierte Teilchen ein Myon ist? Welche technischen Herausforderungen gibt e
 s? Wie nützlich ist eine Funkenkammer heutzutage noch? Inwiefern gibt es Ü
 berschneidungen mit Teilchendetektoren am DESY oder CERN? Das alles versuc
 he ich zu beantworten.\n\nBeim 38c3 habe ich bereits einen Vortrag mit dem
  Titel „Einführung in die Teilchenphysik“ gehalten. Seitdem habe ich viel 
 dazugelernt und freue mich darauf\, dieses Wissen mit euch zu teilen\, mit
  euch in den Austausch zu gehen und euch auf meinem Weg zur angehenden Tei
 lchenphysikerin mitzunehmen.\n\nDer Vortrag ist für alle Lebewesen gedacht
 . Egal ob ihr Vorwissen mitbringt oder nicht.\n\nIch freue mich auf euer K
 ommen!\n

 f\n\nThis is a beginners' workshop on web application security. No prerequ
 isites in web application security are required. A certain (web applicatio
 n) development background is beneficial.\n\nFirst\, we will be playing a v
 irtual escape the room game with challenges on a web application to get in
 to an attacker's mindset.\nThen follows a quick introduction to the OWASP 
 Top 10 vulnerabilities (2025 Release Candidate).\nFinally use the gathered
  knowledge to attack a vulnerable web application (https://github.com/Phyl
 u/vulnerable-click-game) and see how these attacks can easily be prevented
 .\n\nPlease bring your (fully charged) laptop to be able to participate.\n

DESCRIPTION:The tech-libertarian transhumanist narrative is nothing but a h
 ypermodern salvation myth. It is used to propagate a feudalist model of so
 ciety in which a select few reap all the benefits. We discuss this ideolog
 y and how to oppose it.\n**tl\;dr:** A libertarian mindset among tech-affi
 ne people often goes together with political ideas that seem to promote fr
 eedom and progress\, but really stand for a crypto-fascist neufeudalism\, 
 and the transhumanist idea that we can and need to take control of human e
 volution by technological means—in the narrow image of those who promote t
 his view\, and to the detriment of diverse people with other world views o
 r ways of life.\n\nThe inclusion of Joscha Bach's talk at 39C3 and its sub
 sequent cancellation\, after his emails with Jeffrey Epstein were made pub
 lic\, has generated much needed discussion about this close connection bet
 ween **the libertarian right in tech**\, the **TESCREAL** bundle of throug
 ht schools (transhumanism\, extropianism\, singularitarianism\, cosmism\, 
 rationalism\, effective altruism\, and longtermism) [1]\, and covertly or 
 overtly misogynist / queer- & transphobic / misanthropic **patriarchal**\,
  **authoritarian**\, and **fascist ideologies**.\n\nNone of this is partic
 ularly new. Analysis of these connections stretches back decades. It revea
 ls a shocking amount of supremacism\, egotism\, and immaturity\, a profoun
 d lack of responsibility\, the celebration of behavior that targets undesi
 red minorities\, and political incorrectness under the guise of "free spee
 ch\," from the very beginnings of the tech industry to the present moment 
 [2\,3].\n\nLast year\, Bach presented at 38C3\, where he reduced the human
  mind to software\, fetishized the mismeasure of human intelligence by IQ\
 , and called for the effective dehumanization of humanity (quote: "we anth
 ropomorphize people way too much") [4].\n\nRecently\, another connection h
 as been highlighted: that between **transhumanist narratives** and **relig
 ious salvation myths** [5\,6\,7] and **apocalyptic revelations** [8\,9\,10
 ]. The basic idea is that our world is about to unravel and our capacities
  will soon be outclassed by superintelligent machines that—for all practic
 al purposes—take on the role of god(s). For the *accelerationist*\, this i
 s a good thing because\, with the proper alignment\, it will enable us to 
 upload our minds to the cloud\, live forever\, and thus conquer the galaxy
 . For the *doomer*\, surprisingly\, this is not a bad thing either\, becau
 se humanity is but an intermediate stage—crossing Nietzsche's famous <a hr
 ef="https://www.goodreads.com/quotes/384722-man-is-a-rope-stretched-betwee
 n-the-animal-and-the">rope</a>—between the primitive ape descending from t
 he trees and the infallible machines that will inevitably replace us\, mar
 king the next step in some sort of strange imagined *<a href="https://en.w
 ikipedia.org/wiki/Great_chain_of_being">Great Chain of Being</a>*. Human e
 xtinction\, therefore\, is to be welcomed.\n\nIn these **hypermodern apoca
 lypse myths**\, God and the devil in the traditional religious narrative h
 ave simply been replaced by our future machine overlords. Just take Peter 
 Thiel's invocation of the *antichrist* (nicely contextualized and summariz
 ed in [8\,9\,10])\, some sinister force that prevents technological progre
 ss from saving humanity and leading us into our glorious future. Or Bach h
 imself who—in an interview on the Jim Rutt Show—outlined an *Aquinean appr
 oach to alignment*: all it takes to get along with AGI is love\, hope\, an
 d faith [11]. The *apotheotic drive* behind all this is not exactly subtle
 .\n\nSuch dramatic-sounding (and weirdly spiritual) visions of the future 
 cover up a dark political agenda\, sometimes called the **dark enlightenme
 nt** [12\,13]\, which is being implemented in their shadow: a totalitarian
  form of **libertarian neufeudalism** designed to enrich a very small elit
 e of billionaires at the cost of the rest of humanity and the ecological h
 ealth of our planet. The idea is for the chosen few to survive the coming 
 megacrisis without having to worry about us—the other 98%. This side of tr
 anshumanism looks more like a crazed end-time cult than the pan-rationalis
 t utopia it pretends to be in public.\n\nThis entire view is based on an a
 stonishing amount of hubris. It reveals a lack of empathy and human connec
 tion. It is also completely detached from reality\, assuming technological
  capabilities and an individual capacity to survive that are very unlikely
  to ever come to pass. It is a myth in both senses of the term: a visionar
 y narrative for this epoch of late-stage capitalism\, but also a foolish f
 airy tale with no relevance to what is actually going on.\n\nWhat explains
  the **appeal** of such a **delusional** and **anti-human ideology**?\n\nO
 ne reason is widespread *ignorance* when it comes to the true nature of th
 is heterogeneous movement. It does not even try to hide from view but—back
 ed by a spittle-licking tech-media information clique and the idea that "b
 oys will be boys" but that's not too harmful and\, anyway\, this phase wil
 l pass—it manages to cover its tracks quite effectively and to get away wi
 th pretty much anything at the moment—even buying itself a Vice President 
 of the U.S. of A. [14].\n\nThe second reason is the following: in this tim
 e of looming crisis\, a lot of us are looking for *positive visions of the
  future*\, for narratives that suggest workable paths our of our current p
 redicament. This is why many otherwise intelligent and tech-savvy folks ar
 e surprisingly susceptible to the dangerous and anti-social delusion of th
 e hypermodern myth of technological salvation. We desperately *want* it to
  be true.\n\n**Workshop Format:** (60 min)\n\nThis workshop consists of a 
 short (10 min) introductory talk by Yogi Jaeger\, which summarizes the mai
 n theses of his 2023 essay on tech-transcendentalism [7]\, followed by com
 ments from ElleJay.\n\nThe main part of the workshop consists of a **moder
 ated deliberative discussion with the audience**. We want to exchange idea
 s and perspectives\, as well as experiences\, especially from the standpoi
 nts of different minority groups impacted by this ideology.\n\n**The aim o
 f our deliberations is to raise awareness of the presence and influence of
  transhumanist crypto-fascism in the community\, and to come up with speci
 fic strategies how to oppose this problematic ideology while providing alt
 ernative visions for a thriving and diverse humanity in the 21st century.*
 *\n\nThe time is perfect to raise this important topic at 39C3—not just be
 cause of the debate about Bach\, but also because it seems to be garnering
  more and more attention\, at least in English-speaking world.\n\n**Refere

DESCRIPTION:FLINTA kennen meist einige FLINTA\, die sexualisierte Gewalt vo
 n cis Männern erfahren haben\, Cis Männer kennen oft keinen cis Mann\, der
  sexualisierte Gewalt ausgeübt hat. Wie kommt das?\nEin Workshop für Männe
 r.\nWie können Männer über das Thema ins Gespräch kommen? Wie können Männe
 r andere Männer auf sexistisches und grenzüberschreitendes Verhalten anspr
 echen?\nDer Workshop möchte einen Austausch anregen\, welche Barrieren es 
 gibt\, andere Männer auf problematisches Verhalten anzusprechen\, aber auc
 h darüber\, wie diese überwunden werden können. Es geht nicht darum\, FLIN
 TA ausschließlich als Betroffene anzusehen und cis Männer ausschließlich a
 ls Ausübende. Dennoch ist es wichtig\, dass (cis) Männer Verantwortung übe
 rnehmen und solche Gespräche führen. Als solidarische Praxis\, aber auch a
 ls Prävention. \nIm Workshop können Ideen\, Erfahrungen und Strategien mit
 einander geteilt oder zusammen entwickelt werden. Also kommt vorbei\, wenn
  ihr diese Gespräche bereits führt\, wenn ihr euch bisher noch nicht getra
 ut habt oder auch\, wenn ihr ein so cooles Umfeld habt\, dass sie gar nich
 t nötig sind.\n\nDer Workshop richtet sich an Männer. Wir werden dies auch
  zu Beginn formulieren\, aber wir wollen natürlich keine Nachweise. \nJuli
 an [er/ they] und buecherwurm [sie/ ihr\, agender] werden den Workshop beg
 leiten\, buecherwurm wird sich auf den methodischen Rahmen fokussieren und
  vermutlich irgendwann rausziehen.\n

DESCRIPTION:Alle Monate wieder bluten einige von uns. Aber das ist nicht al
 les. Der Menstruationszyklus ist so viel mehr. In diesem Workshop wollen w
 ir erkunden wie wir unsere Hormone und deren Schwankungen besser verstehen
  können\, um sie zu hacken.\nIn diesem Workshop geht es um die Mutter alle
 r Zyklen: den Menstruationszyklus. Wir werden über Chronobiologie\, Ernähr
 ung\, Sport\, Schwangerschaft\, PMS\, PMDD\, Migräne\, PCOS\, Endometriose
 \, Thermometer\, Wärmflaschen und den Mond sprechen. Und natürlich den Anf
 ang und das Ende. Der Workshop soll Gelegenheit bieten sich über den Zyklu
 s auszutauschen. Alle mit eigener Menstruationserfahrung sind willkommen. 
 Dazu zählen Erfahrungen mit dem Menstruationszyklus\, die in der Vergangen
 heit liegen\, nur sporadisch auftreten oder durch Hormontherapie ausgelöst
  oder pausiert wurden. Wir möchten in diesem Haecksen-Skillshare versuchen
  das Thema in seiner ganzen Bandbreite zu besprechen und unterschiedliche 
 Perspektiven zu hören. Alle die systematisch Zyklusdaten erfassen oder erf
 asst haben und ihre Erkenntnisse daraus teilen möchten\, sind herzlich daz

DESCRIPTION:\nChaos Communication Congress (C3) is a major annual gathering
  for people passionate about technology\, cybersecurity\, free culture\, a
 nd creativity. Since 1984\, it has taken place in Germany and initially us
 ed mostly German\, then English to facilitate international communication.
 \n\nToday\, thanks to International Sign (IS)\, everyone—deaf or hearing—c
 an fully participate. IS makes exchanges open\, accessible\, and equal\, a
 llowing people to overcome language barriers and collaborate easily.\n\nDi
 d you know there are over 300 sign languages in the world\, some existing 
 for more than 5\,000 years? IS has been used for several decades by the Wo
 rld Federation of the Deaf (WFD) and the Deaflympics Games (ICSD). Traditi
 onally\, these organizations imposed a hierarchy\, but today IS allows a h
 olarchy\, where everyone has a place and communication is shared and equal
 .\n\nA big question arises: why choose English instead of International Si
 gn? English was adopted to facilitate communication among hearing particip
 ants worldwide. But International Sign allows us to connect deaf and heari
 ng people in a more universal way\, opening a space for equal sharing and 
 helping to prevent ignorance about deaf cultures and their languages.\n\nA
 t 39C3\, IS helps connect diverse cultures: hack\, free\, maker\, and deaf
 \, fostering creativity\, collaboration\, and innovation.\n\nOur project\,
  Nest of Sign Language at House of Tea\, offers workshops where participan
 ts can practice International Sign (IS)\, German Sign Language (DGS)\, Aus
 trian Sign Language (OGS)\, French Sign Language (LSF)\, British Sign Lang
 uage (BSL)\, American Sign Language (ASL)\, and more\, as well as create\,
  share\, and connect in a friendly and inspiring environment. Some IS inte
 rpreters are certified\, but will they be present at 40C3? Conferences and
  workshops become opportunities to learn\, share\, and dream together\, re
 gardless of language or background.\n

 \nDies ist die Hands-on-Session zum Talk "CPU-Entwicklung in Factorio: Vom
  D-Flip-Flop bis zum eigenen Betriebssystem"\n(https://events.ccc.de/congr
 ess/2025/hub/en/event/detail/cpu-entwicklung-in-factorio-vom-d-flip-flop-b
 is-zum-eigenen-betriebssystem).\n\nIn dieser Session zeige ich\, wie man m
 eine CPU in Factorio lädt\, wie man\nAssembly-Programme dafür schreibt\, s
 ie assembliert und schließlich in\nFactorio ausführt.\n\nZum Mitmachen sol
 ltet ihr **Factorio** bereits installiert haben\n(Grundspiel\, nicht die E
 rweiterung *Space Age*).\nGetestet habe ich Factorio über Steam auf Window
 s und Ubuntu (mit Proton\n10.0\; Guide für Linux-Installation von Steam-Ga
 mes:\nhttps://ubuntu.com/blog/linux-gaming-with-ubuntu-desktop-steam-and-p
 roton).\nOhne Factorio könnt ihr eure Assembly-Programme nur auf einem\nPy
 thon-Simulator ausführen.\n*(Factorio ist übrigens generell ein sehr gutes
  Spiel\, das ich\nuneingeschränkt empfehlen kann …)*\n\nFür den Assembler 
 benötigt ihr eine Python-Umgebung und müsst ein\nGitHub-Repository clonen.
 \nFür die Bedienung in Factorio empfehle ich außerdem eine Maus\, auch wen
 n\nsie nicht zwingend notwendig ist.\n\nIm Detail werden wir:\n\n- Den Fac
 torio-Worldsave meiner CPU in Factorio öffnen\n- Alle benötigten Quality-o
 f-Life-Mods installieren\n- Die vorinstallierten Programme auf der CPU tes
 ten\n- Das Assembler-Repository clonen und den Python-Assembler einrichten
 \n- RISC-V-Assembly kennenlernen\n- Ein erstes kleines Programm schreiben\
 n- Das Programm assemblieren\n- Den Blueprint in Factorio laden\n- Das eig
 ene Programm in Factorio ausführen!\n\nIch freue mich sehr über Anregungen
  und Fragen.\nWenn beispielsweise jemand Interesse hätte\, für diese CPU e
 inen Compiler\nzu bauen\, wäre ich ganz Ohr! :)\n

DESCRIPTION:\nThe system of harassing payment cards for people receiving as
 ylum seeker benefits is not a new idea\, but has been dusted off from the 
 1990s/2000s. But even back then\, there was resistance—including in Thurin
 gia!\n\nWe are showing “Change?! – No way!”\, a 25-minute documentary by F
 ilmpirat*innen about the voucher system for refugees. Using hidden cameras
 \, the film pirates in Thuringia accompanied refugees while shopping to sh
 ow the everyday\, discriminatory madness at supermarket checkouts when vou
 chers have to be “used up” during a shopping trip or dictionaries “can't b
 e bought with vouchers.” But they also show the everyday solidarity of peo
 ple who exchange vouchers 1:1 for cash in exchange initiatives and do not 
 stop there\, but generally demand the abolition of the voucher practice – 
 the precursor to today's payment cards.\n

DESCRIPTION:„Water to Voice“ ist ein sich ständig weiterentwickelndes Werk\
 , das aus dem Prozess des Klonens von Lisas Stimme entstanden ist. Der Flu
 ss und die Bewegung des Wassers steuern und lösen die Stimme aus und schaf
 fen so ein einzigartiges Zusammenspiel zwischen den beiden Elementen. Es f
 ängt die Stimme mitten in ihrem Trainingsprozess ein – wie sie sich veränd
 ert\, stolpert und neu interpretiert.\nWährend sich das Wasser bewegt\, fo
 rmt und unterbricht es den Klang und verwandelt die Bewegung der Flüssigke
 it in eine stimmliche Geste. Das Ergebnis ist weder rein menschlich noch r
 ein künstlich\, sondern etwas dazwischen – lebendig\, instabil und sich st
 ändig verändernd. „Water to Voice“ wird zu einem Dialog zwischen Natur und
  Technologie\, einer fragilen Choreografie\, in der die Stimme in Echtzeit
  lernt\, ins Stocken gerät und sich weiterentwickelt.\n»Water to Voice« is
  an evolving piece born from the process of cloning Lisa’s voice. The flow
  and movement of water control and trigger the voice\, creating a unique i
 nterplay between the two elements. It captures the voice in the midst of i
 ts training—shifting\, stumbling\, reinterpreting itself.\nAs the water mo
 ves\, it shapes and disrupts the sound\, transforming liquid motion into v
 ocal gesture. What emerges is neither purely human nor purely artificial\,
  but something in between—alive\, unstable\, and constantly transforming. 
 »Water to Voice« becomes a dialogue between nature and technology\, a frag
 ile choreography in which the voice learns\, falters\, and evolves in real
  time.\n\nArtist Bio:\n\nThe duo Lisa L. Zwinzscher & Nina Bendix Igleses 
 (Leipzig/Weimar) explores the boundaries of listening and voice in the dig
 ital realm. Emerging from Lisa L. Zwinzscher’s solo project Pony Pracht\, 
 which blends music with interactive\, game-inspired visuals\, her work exp
 ands to questions of identity and authenticity in the age of AI. As a sing
 er\, she has cloned her own voice\, transforming it into a human-artificia
 l live instrument. \nFascinated by the tactile\, sonic and metaphorical qu
 alities of water\, Nina Bendix Igleses approaches listening as a multisens
 ory practice of relating to the world\, investigating interconnection with
 in and between self and environment.\nTogether\, they engage with question
 s of identity\, resonance\, and transformation\, creating sonic environmen
 ts that explore what it means to be human.\n\n\n[ponypracht.com](https://p

DESCRIPTION:\nThe initiative “No to Payment Cards Leipzig” organizes the so

 nexpress. The app is freely available on codeberg.org and comes with instr
 uctions for use. The app is only used within the group to manage an orderi
 ng system for vouchers. With the help of the app\, voucher orders from sol
 idarity buyers can be matched with the vouchers actually available after a
 n exchange\, and the distribution to be made can be calculated. Without th
 e app\, the now large number of vouchers to be distributed would no longer
  be manageable\, and it would not be possible to help so many people obtai
 n more cash to circumvent the discriminatory payment card system.\n\nIn th

DESCRIPTION:\nWährend wir uns auf dem 37C3 noch begeistert Aktionsstrategie
 n der Hongkonger Demokratiebewegung abgeguckt haben\, sind mittlerweile ei
 ne halbe Million HongkongerInnen ausgewandert\, geflohen\, oder im Knast. 
 Seit dem Niederschlagen des Aufstands und der Installation des Nationalen 
 Sicherheitsgesetzes hört man aus der Stadt nicht mehr viel. Wer ist da noc
 h? Wie weit ist ein chinesischer Überwachungsstaat installiert? Und wie ge
 hen Menschen mit der neuen Wirklichkeit um? Um diese Fragen zu beantworten
 \, bin ich für ein halbes Jahr nach Hongkong gezogen. Das Buch „nach der R
 evolte“ (Alibri Verlag\, Februar 2026) bietet Einblicke in die politische 
 Gegenwart vor Ort\, durch Gespräche mit HongkongerInnen\, dem Nachzeichnen
  der technopolitischen Veränderungen der letzten Jahre\, und dem Beschreib

 as Ganze ergibt ein Bild – von Resilienz und Ohnmacht\, und von der Fragil
 ität von Systemen\, in denen schon ein\, zwei Updates reichen\, um eine Ge
 sellschaft gänzlich zu ändern.\n\n„Im Film La Haine wird die Geschichte ei

 er sagt: Bis hierher lief’s noch ganz gut. Das sind wir\, wenn wir denken\
 , dass unsere Gesellschaftsordnung grundsätzlich eine ist\, die unsere pol
 itischen Freiheiten hält. Das Gegenteil ist der Fall. Nichts an dieser Ord
 nung schützt sie\, außer die temporäre\, arrogante Blindheit vor dem eigen

DESCRIPTION:\nDer 19. April 2023 war für die anarchistische und antiautorit
 äre Bewegung ein schwerer Schlag. Drei Aktivist\\*innen wurden an der Fron
 t in der Ukraine in einem Hinterhalt getötet: Dmitri Petrow aus Russland\,
  Finbar Cafferkey aus Irland und Cooper Andrews aus den USA. Am 9. Septemb
 er wäre Dimas Geburtstag und zu diesem Anlass haben wir die Broschüre „Dmi
 try Petrow“\, die 2023 von CrimethInc veröffentlicht wurde\, ins Deutsche 
 übersetzt\, um weitere Texte ergänzt und aktualisiert. In seinem letzten B
 rief schrieb Cooper\, dass der Krieg vermutlich nicht so schnell vorbei se
 in wird\, und er behielt recht. Die Hoffnung auf ein baldiges Ende ist ver
 schwunden. Die Folgen des Krieges\, wenn er doch irgendwann zu Ende sein w
 ird\, die physische und psychische Zerstörung der ukrainischen Gesellschaf
 t im Allgemeinen und der anarchistischen Bewegung im Besonderen sind unvor
 stellbar. Wir möchten mit euch gemeinsam an die erinnern\, die nicht mehr 
 mit uns sind. Wir werden bei dieser Veranstaltung aus dem Buch lesen\, Spe
 nden für unsere Genoss\\*innen sammeln und mit euch ins Gespräch kommen. W
 ir wollen die Stimmen von Dima\, Finbar und Cooper hörbar machen\, die ein
 e schwerwiegende Wahl getroffen und dafür einen hohen Preis gezahlt haben.
  Was haben sie uns zu sagen? Was bedeutet das für uns? Und welche Schlüsse

DESCRIPTION:What might future p2p networks look like?\nIn the early 2000s\,
  a range of p2p network structures were explored. This led to systems in u
 se today for both coordination (like DHTs) and communication (like Gossipi
 ng).\n\nWe have more tools today to model\, prototype\, and evaluate struc
 tures. The first step though is to imagine them.\nWhat can we design to re
 ach cases beyond DHTs? - What might network-level structures look like tha
 t might be safer\, more scalable\, more private\, and/or more resilient th
 an the ones we have today?\n\nTables will be provided with seeding inspira
 tion and paper for recording ideas\, to serve as inspiration for subsequen

 of Delay Tolerant Networks\, Bundle Protocol and Archipel.\nDelay Tolerant
  networks are special kinds of network that allow messages to be transmitt

DESCRIPTION:Developing\, using\, and re-using [Free Software](https://fsfe.
 org/freesoftware/index.en.html) is fun\, but declaring licensing and copyr
 ight information is not. [REUSE](https://reuse.software/) changes that. Wi
 th three simple steps\, it makes declaring licensing and copyright informa
 tion unambiguous and perfectly human- and machine-readable.\n\nThis is an 
 interactive workshop as an introduction to the REUSE project and demonstra
 tion of how to make a repository REUSE compliant.\nAs software has gotten 
 more complex over the last years\, the importance of declaring licensing i
 nformation has become even more crucial. The FSFE's REUSE initiative contr
 ibutes to the goal of clearly displaying legal information in Free Softwar
 e projects by embedding it into every file of the repository. Any project 
 following the REUSE recommendations makes copyright and licensing informat
 ion readable for both humans and machines. We ensure that individuals\, or
 ganizations\, and companies that are reusing code are aware of and respect
  the license terms chosen by its original author\, thus making life easier
  for everyone involved in the software supply chain .\n\nREUSE integrates 
 seamlessly into development processes and other best practices of indicati
 ng Free Software licenses. In addition\, there are tools and documentation
  to help you get started.\n

 might that look and function? To what extent would it be democratic and su
 stainable? Who would (not) benefit from it?\n\nIn this workshop\, we would
  like to think through\, examine and discuss alternative models for the ow
 nership and management of collective data centres. We will take a structur
 ed look at fundamental concepts\, governance issues and implications\, as 
 well as discuss parallel ideas in other areas (cooperative banks or housin
 g\, community-supported agriculture) in the hope of initiating a broad dis
 cussion about alternatives to the profit and exploitation logic of the cur
 rent data centre industry. Similar approaches to data centers that already
  exist include Nubo (Belgium)\, Espora (Mexico) and Wobcom (Germany).\n

DESCRIPTION:In our struggles for a better world\, we need the right tools t
 o organize collectively. Common solutions seldom align with our ideals of 
 self-organization and freedom from hierarchy. But what tools work in conte
 xts with activists who have little technical experience? And what is our r
 ole as hackers in these groups? We see the same challenges in other organi
 zations building up counterpower through structure based organizing as wel
 l. So let's connect!\nWe are tenants organizing ourselves in the Berlin Te
 nants Union to fight for better housing conditions. In our organization\, 
 we have some active members that need to plan\, coordinate and document ac
 tions. At the same time\, we are constantly growing with new members who h
 ave little experience in collective struggles. Onboarding them shouldn’t b
 ring a steep learning curve\, but rather empower people to participate rig
 ht-away. So we need tools that require only a low level of technical exper
 tise to get started.\n\nYet we’re facing a gap between our values (data so
 vereignty\, open source\, collective ownership) and our reality (onboardin
 g friction\, technical barriers\, competing with Big Tech UX). But we are 
 the advanced users in the technical sphere. So where do less technical use
 rs face difficulties so that they choose tools that don't align with our v
 alues? And are we mere facilitators or also educators in these spaces? Tha
 t’s why we would like to exchange with like-minded people.\n\nSo let's con
 nect and talk about the toolbox we want!\n\n\n\nSome questions we would li
 ke to discuss:\n- How can information and shared knowledge made accessible
  for new members?\n- How can events be communicated and how can we mobiliz
 e for specific actions?\n- Where should we store contact information from 
 the people we organize?\n- How can we keep track of active members?\n- And
  what is our position as hackers in all of that?\n

DESCRIPTION:Let's start to make our hackspaces and community networks multi
 cast interconnected!\nMulticast allows to send information\, for example a
 udio or video streams\, sensor data or service discovery messages\, to man
 y interested recipients with minimal overhead\, without the need of a cent
 ral\, beefy server. A perfect fit with a decentral network like [dn42](htt
 ps://dn42.dev/) or [Freifunk](https://freifunk.net/)?\n\nThe fundamental s
 tandards for multicast aren't new but usable\, "bugfree" implementations h
 ave been rare in the past. And multicast is typically not available on com
 mon consumer internet connections.\n\nThe former has changed though\, grea
 t progress was made in OpenSource software\, including Freifunk firmwares 
 and mesh routing protocols\, in recent years. Allowing us to experiment wi
 th this and potentially making it available to and from a wider\, public\,
  distributed audience and providers.\n\nTo really unfold the potential of 
 multicast and to tackle the chicken & egg problem it will be crucial to es
 tablish a multicast topology with a wide reach. So let's start with making
  our hackspaces and community networks multicast interconnected!\n\n---\n\
 nThis session will kick off with a small presentation on IPv6 multicast ro
 uting. Followed by a practical\, hands-on workshop to set up IPv6 multicas
 t peerings based on PIM-SD ([RFC7761](https://www.rfc-editor.org/rfc/rfc77
 61)) over dn42. While the presented tooling will focus on [bird](https://b
 ird.network.cz/) with a dedicated [BGP](https://en.wikipedia.org/wiki/Bord
 er_Gateway_Protocol) multicast channel + [pim6sd](https://github.com/trogl
 obit/pim6sd) experimentation and discussion on other tools (maybe [FRR](ht
 tps://frrouting.org/)?) and approaches will be highly encouraged.\n\nPrere
 quisites: For the workshop part you should have a dn42 node or other BGP e
 nabled router set up and connected beforehand and should have some experie
 nce with IPv6 unicast routing. Also feel free to stop by in the [#dn42-mul
 ticast](https://events.ccc.de/congress/2025/hub/tag/dn42-multicast) IRC ch
 annel on [HackInt](https://hackint.org/) in advance. Having some more "bet
 a testers" and potential people to onboard others during the session would
  be appreciated :-).\n\nIf you are a commercial ISP or research institute 
 with potential multicast peering opportunities for our community networks 
 then we would also be very interested to hear from you.\n

 ight sound or mechanical circuits. The electronic building blocks from OEM
  Dbolo are not only especially child-friendly due to their simple push-but
 ton connections but also a lot of fun for all ages. They are distributed b
 y various brands\, including "Kosmos Easy" and "Elenco Snap Circuits." No 
 prior knowledge of electricity is required\, but beware - learning somethi
 ng might happen! This is an open parent-child activity. Learn\, build\, an
 d play together\, and take care for arguments and that the parts don’t fal
 l on the floor. Teenagers and adults are also welcome without child accomp
 animent. \;-)\n

DESCRIPTION:Up-Cycling wörtlich genommen: Aus alten Fahrradketten entstehen
  verschiedene Fidgettoys zum Mitnehmen. Verschiedene Varianten können ausp
 robiert und Favoriten gleich selber nachgebaut werden. – Mit Anmeldung im 
 Vorfeld. –\nPassend zum „Cycle“ im Kongresstitel zeige ich in diesem klein
 en Workshop\, wie aus alten Fahrradketten Fidgettoys gebastelt werden könn
 en. Im Vorfeld zeige ich einige verschiedene Varianten\, die auch ausprobi
 ert werden können\, und dann geht es auch schon los. Geplant ist\, dass je
 de Teilnehmer*in mit ein bis zwei Fidgettoys aus dem kurzen Workshop geht.
  Zusätzlich zu den Fahrradketten kommen Schlüsselringe und Schrumpfschlauc
 h zum Einsatz\, aber nicht bei allen Varianten.\n\nDa es sich wirklich um 
 alte Fahrradketten handelt\, die ich zwar etwas vorreinige\, macht es denn
 och die Hände schmierig und dreckig. Es wird aber Babyfeuchttücher geben u
 nd einen Pott Handwaschcreme\, der für solche Zwecke gut funktioniert\, da
 mit nachher alle wieder saubere Hände haben.\n\nDieser Workshop ist für al
 le ab 16. Ich werde im Vorfeld Listen zum Eintragen aufhängen. Geplant sin
 d zwei kürzere Workshop-Slots zu je 30 Minuten in Gruppen von sechs bis ac
 ht Personen.\n

DESCRIPTION:How does live techno work?\nOn the dance floor\, it's practical
 ly impossible to understand what's happening up front. It's also irrelevan
 t there\, because it's all about the music and many other things.\n\nLive 
 sets have a thousand faces. Everyone has their own workflow\, and there ar
 e countless approaches to performing electronic music. I don't know all of
  them\, but I will give a deeper insight into the architecture of my setup
  in this short presentation. I explain my approach to improvising techno i
 n clubs and at festivals. \n\nThere will be a few technical insights into 
 my „Ableton“ structure. A fixed structure with an unknown outcome. Because
  at certain points\, I rely on random generators to create the desired ele
 ment of surprise. This keeps me inspired for hours\, again and again. I wi
 ll show and explain why I make music this way.\n

DESCRIPTION:Finally a drag show at the chaos! Blinking lights\, colorful ou

  can it be\, that all of this did not come together as drag on stage?! It 
 is time for a really awesome\, great drag show at the 39c3!\nAnd to show r
 ight away how divers drag is\, a wonderful cast of drag artists of various
  genders and expressions can spread their queer joy and art for the audien
 ce.\n\nThe show is hosted by Milky Gay\, the nerdiest drag king from NRW\,
  who does not only want to throw glitter at the congress incognito this ye
 ar. And he is bringing an amazing cast with him\nBingus Bongus (Drag Queen
 \, Hamburg)\nNeuro Spicy (Drag King\, NRW)\nMissass Nostalgia (Drag Queen\
 , NRW) and\nKaín Mensch (Drag Thing\, Hamburg)\nwill bring their queer art
  to finally merge chaos and drag!\n\nEveryone is welcome\, we are trying t
 o have as little barriers as possible to come and watch. No blinking light
 s during the show (no guarantee for the path there and acts before and aft
 er)\, Music Club accessible with mobility aids and wheel chairs (ask assig
 ned angles). Mostly standing room\, few seats at the side might not allow 
 for a good view of the show. Content notes for certain parts of the show i
 nclude death\, cancer\, violence\, fake weapons\, and sexual violence\, an
 d will be announced in time so people can leave and come back afterwards. 
 Cheering is encouraged\, so it might get loud. (more details tba). Please 
 be nice to each other and especially help short people as well as queers t
 o find a spot where they can see enough. Also\, as drag is expensive\, the
 re will be a tipping round in the end - please bring some cash if you cons
 ider tipping the artists\, but of course you are also welcome either way.\

DESCRIPTION:In my improvised live set\, my random generators and I bounce i
 deas off each other. This approach allows previously created loops to flow
  into endless new combinations.\nI love loopy and trippy techno. When danc
 ing\, I like to let go of everything around me and enter a deeper dialogue
  with myself. At this stage\, I am 100% in tune with myself. This works fo
 r me when the groove drives me and the elements I hear are interesting but
  not too intrusive. That’s exactly what I love to create on the dance floo
 r.\n\nTo achieve this—and to create the necessary element of surprise—I co
 mbine different loops randomly and "blindly". Since I never know exactly w
 hat will happen\, I am constantly surprised and inspired by the result.\n

DESCRIPTION:Data about greenhouse gas emissions\, both from countries and i
 ndividual factories\, is\noften publicly available. However\, the data sou
 rces are often not as accessible and\nreliable as they should be. EU emiss
 ion databases contain obvious flaws\, and nobody\nwants to be responsible.
 \nWhich factory in my city is the largest emitter of CO2? Which industrial
  sector is\nresponsible for the largest share of a country's contribution 
 to climate change? It\nshould not be difficult to answer these questions. 
 Public databases and reporting\nrequired by international agreements usual
 ly allow us to access this data.\n\nHowever\, trying to access and work wi
 th these datasets — or\, shall we say\, Excel tables\n— can be frustrating
 . UN web pages that prevent easy downloads with a "security\nfirewall"\, b
 arely usable frontends\, and other issues make it needlessly difficult to\
 ngain transparency about the sources of climate pollution.\n\nWhile workin
 g with official EU datasets\, the speaker observed data points that could 
 not\npossibly be true. Factories suddenly dropped their emissions by order
 s of magnitude\nwithout any explanation\, different official sources repor
 t diverging numbers for the\nsame emission source\, and responsible Europe
 an and National authorities appear not to\ncare that much.\n\nThe talk wil
 l show how to work with relevant greenhouse gas emission data sources and\
 nhow we can access them more easily by converting them to standard SQL tab
 les. Furthermore\, we will dig into some of the\nstrange issues one may fi
 nd while investigating emission datasets.\n\n# Background / Links\n\n* Why

DESCRIPTION:Learn how to find your position using a sextant and a custom sl
 ide rule\, almost no math required!\nSince the dawn of time people have as
 ked themselves: where am I and why am I here?  This talk won't help you an
 swer the why question\, but it will discuss how determine the where in the
  pre-GPS age of sextants\, slide rules and stopwatches by taking the noon 
 sight\, aka the meridian passage.\n\nThe usual way to find your position u
 sing the Sun requires a large almanac of lookup tables and some challengin
 g math.  The books are frustrating to consult on every sight and the base 
 60 degree-minute-second math is frustrating even with a calculator\, and i
 f you're on a traditional ship it seems wrong to do traditional navigation
  with electronic devices.\n\nTo speed up the process I’ve designed a speci
 alized circular slide rule that handles most of the table lookups to corre
 ct height of eye\, semi-diameter\, temperature\, refraction and index erro
 rs\, and also simplifies the degree-minute-second arithmetic required to c
 alculate the exact declination of the Sun.\n\nIn this talk I’ll demonstrat
 e how to make your own printable paper slide rule and use it to reduce the
  meridian passage measurement to a lat/lon with just a few rotations of th
 e wheels and pointer\, no electronics or bulky books necessary!\n

DESCRIPTION:Bike- and e-bike-sharing promise sustainable\, equitable mobili
 ty - but what makes these systems successful? Despite hundreds of cities o
 perating thousands of shared bikes\, trip data is rarely public. To addres
 s this\, we built a geospatial analysis pipeline that reconstructs trip da
 ta from publicly accessible system status feeds. Using this method\, we ga
 thered **43 million km** of bike-sharing trips across **268 European citie
 s**. Combined with over **100 urban indicators** per city\, our analyses r
 eveal how infrastructure\, climate\, demographics\, operations\, and polit
 ics shape system performance. We uncover surprising insights - such as why
  some e-bike systems underperform despite strong demand - and highlight ho
 w cities can design smarter\, fairer mobility. All data and code are open-
 source\, with an interactive demo at bikesharingflowmap.de.\nWe are Felix\
 , Georg\, and Martin - each of us working professionally in different rese
 arch and data areas\, ranging from the future of mobility to computational
  fluid dynamics and machine learning. What unites us is our shared interes
 t in **quantitative traffic analyses**. Building on earlier small-scale st
 udies focused on individual cities\, we set out to launch a project that c
 aptures shared bike system data across Europe - from regular bikes to e-bi
 kes.\n\nIn our study\, which led to an **[open-access scientific publicati
 on](https://doi.org/10.1007/s11116-025-10661-2)**\, we scraped shared bike
  data across Europe at a **minute-by-minute level** over many months\, acc
 umulating **more than 43 million records**. We analyze **behavioural and s
 ystemic patterns** to understand what makes a bike-sharing system useful a
 nd successful within a city. As such\, this evidence-based research fits v
 ery well with the **39C3 Science track** and the theme of "**Power Cycles*
 *" as we dissect the complex energy and usage cycles that define urban mob
 ility and sustainable futures for everyone. We bridge the gap between urba
 n planning\, socioeconomics\, and technology by applying statistical model
 ing and engineering knowledge to a large-scale mined dataset. Join us to l
 earn whether right-wing politics stall sustainable mobility\, or which cli
 mate e-bikes feel most comfortable in!\n\nWe love going the extra mile and
  therefore provide a live\, interactive demo that everyone can use to expl
 ore and understand traffic flows: [bikesharingflowmap.de](https://bikeshar
 ingflowmap.de/). Therefore\, attendees will be able to play with the data 
 in a self-service way. We also provide all code on GitHub and the complete
  dataset on HuggingFace. And\, of course\, we will also discuss how both b
 ike-sharing operators and our boss reacted when we told them about the dat
 aset we already had collected (spoiler: lawyers were involved\, yet it’s s
 till available for downloads…).\n

DESCRIPTION:Wer überhaupt „neutral“ sein muss\, was das bedeutet\, und wer 
 sich jetzt wehren muss.\n„Neutralität“ wird zum neuen Kampfbegriff: Weil s
 ie gegen die menschenfeindliche Politik von Friedrich Merz protestieren\, 
 wirft die CDU Gruppen wie Omas gegen Rechts\, Greenpeace und Correctiv vor
 \, nicht neutral zu sein. Unter Berufung auf ein angeblich verletztes Neut
 ralitätsgebot werden staatliche Förderungen gestrichen und NGOs geraten un
 ter Beobachtung des Verfassungsschutzes.\nJulia Klöckner verbietet im Name
 n der „Neutralität“ Palestine-Shirts\, Anstecknadeln und Regenbogenflaggen
  im Parlament. Die AfD fordert dazu auf\, Lehrkräfte zu melden\, die sich 
 gegen Rechtsextremismus einsetzen oder entsprechende Positionen innerhalb 
 der AfD kritisieren.\nDoch was steckt dahinter?\nWas bedeutet das sogenann
 te Neutralitätsgebot – und für wen gilt es überhaupt?\nUnd für wen gilt es
  nicht?\nZivilcourage kann nicht neutral sein – und soll es auch nicht sei
 n. Genauso wie AfD-Hetze gegen Migrant*innen nicht „neutral“ ist\, ist die
  Kritik menschenfeindlicher Äußerungen nicht nur legitim\, sondern Pflicht
  demokratischer Bürger*innen. Das Beschwören eines „Neutralitätsgebots“ fü
 r NGOs ist ein durchschaubarer\, aber gefährlicher Versuch\, sie der eigen
 en Position zu unterwerfen.\nDie Rechtsanwältinnen Vivian Kube und Hannah 
 Vos erklären den verfassungsrechtlichen Hintergrund\, zeigen die autoritär
 en Strategien hinter dem Ruf nach „Neutralität“ auf und geben Tipps\, wie 
 man sich dagegen wehren kann.\nSie engagieren sich im Projekt Gegenrechtsc
 hutz\, um demokratische Prinzipien und Betroffene vor rechtlichen Angriffe

DESCRIPTION:Nicht zuletzt durch die Werbung in den sozialen Medien werden i
 n Deutschland immer mehr Nahrungsergänzungsmittel verkauft. Einige Influen
 cer bringen sogar ihre eigenen Präparate auf den Markt. Gleichzeitig häufe
 n sich Fälle\, in denen die Einnahme von vermeintlich harmlosen „Supplemen
 ts“ zu Gesundheitsschäden geführt hat. Der Vortrag will daher die Mechanis
 men hinter dem Supplement-Hype aufzeigen\, zudem erklären\, warum aktuell 
 ein ausreichender Verbraucherschutz insbesondere im Internet nicht gewährl
 eistet werden kann\, wo Handlungsbedarf für die Politik besteht und wie ma
 n sich selbst vor fragwürdigen Produkten schützen kann.\nDer Markt für Nah
 rungsergänzungsmittel boomt seit Jahren. Dafür sorgen unter anderem versch
 iedenste Influencer\, die die Präparate in den sozialen Medien bewerben. S
 tatt nur Produkte der großen Player in diesem Bereich anzupreisen\, wie Mo
 re Nutrition\, ESN oder Holy Energy\, haben einige Influencer mittlerweile
  sogar ihre eigenen Nahrungsergänzungsmittelmarken auf den Markt gebracht.
 \n\nVersprochen wird dabei vieles: Pre-Workout-Booster sollen die Leistung
  beim Krafttraining erhöhen und blitzschnell zum Traumkörper verhelfen\, w
 ährend Gaming-Booster Wachheit und eine Top-Performance beim Zocken verspr
 echen. Wieder andere Kapseln oder auch Gummibärchen sollen für eine makell
 ose Haut oder einen ruhigen Schlaf sorgen. Manche Präparate können angebli
 ch sogar Krankheiten vorbeugen oder heilen.\n\nDoch was steckt tatsächlich
  in diesen Mitteln\, die online regelrecht gehypt werden? Rein rechtlich h
 andelt es sich um Lebensmittel\, was wiederum bedeutet\, dass sie ohne beh
 ördliche Zulassung auf den Markt gebracht werden dürfen. Es genügt schon\,
  wenn der Unternehmer für die Sicherheit garantiert. Die Hürden für einen 
 Marktzutritt sind damit denkbar niedrig\, während gleichzeitig Gewinnmarge
 n locken\, die sogar den illegalen Drogenhandel übertreffen.\n\nDas Ergebn
 is zeigt sich in den Berichten der amtlichen Lebensmittelüberwachung: Bei 
 den Proben\, die das Niedersächsische Landesamt für Verbraucherschutz und 
 Lebensmittelsicherheit im Jahr 2024 untersucht hat\, entsprachen rund neun
  von zehn Proben (89 %) nicht den rechtlichen Vorgaben. Neben Mängeln bei 
 der Kennzeichnung und Bewerbung\, wodurch Verbraucher viel Geld für wirkun
 gslose Pulver ausgeben\, ist die stoffliche Zusammensetzung der Produkte b
 esonders kritisch. So kann beispielsweise die Einnahme von überdosierten V
 itamin-D-Präparaten zu Störungen des Calciumstoffwechsels führen (sog. Hyp
 ercalcämien). Vermeintlich harmlose pflanzliche Präparate\, wie Kurkuma od
 er Ashwaganda\, können zu Leberschäden bis hin zum Leberversagen führen. B
 esonders brisant ist dabei\, dass die Wahrscheinlichkeit für die Erforderl
 ichkeit einer Lebertransplantation oder den Tod des Patienten höher ist al
 s bei Leberschäden durch Arzneimittel (83 vs. 66 %). Es kommen also Mensch
 en durch die Einnahme von Präparaten zu Schaden\, mit deren Hilfe sie ihre
 r Gesundheit eigentlich etwas Gutes tun wollten.\n\nDer Vortrag beleuchtet
  daher die aktuelle Marktsituation unter besonderer Berücksichtigung des I
 nfluencer-Marketings kritisch\, erklärt den Unterschied zwischen Nahrungse
 rgänzungs- und Arzneimitteln und stellt die rechtlichen Rahmenbedingungen 
 für das Inverkehrbringen und die Bewerbung von Nahrungsergänzungsmitteln d
 ar. Zudem wird aufgezeigt\, warum ein ausreichender Verbraucherschutz durc
 h die aktuellen Möglichkeiten des Lebensmittelrechts insbesondere im Inter
 net nicht gewährleistet werden kann\, wo Handlungsbedarf für die Politik b
 esteht und wie man sich selbst vor fragwürdigen Produkten schützen kann.\n

DESCRIPTION:Seit Mitte 2025 steht die elektronische Patientenakte für alle 
 zur Verfügung – nach ein paar kleineren oder größeren Sicherheitsproblemen
  im Vorfeld\, sei es vor einem Jahr auf dem 38C3 oder Ende April zum deuts
 chlandweiten Start. \nZeit ein Fazit zu ziehen: Ist die ePA jetzt sicher? 
 Wurden nachhaltige Veränderungen durchgeführt\, die zu mehr Sicherheit füh
 ren? Kann der Umgang mit der IT-Sicherheit «eines der größten IT-Projekte 
 der Bundesrepublik» für zukünftige Digitalprojekte hilfreich sein?\n\nZeit
 \, mit etwas Abstand auf das zu blicken\, was war\, was ist und was sich a
 bzeichnet nicht nur bei der ePA\, sondern auch beim Umgang mit IT-Sicherhe
 it bei ähnlichen Vorhaben in Deutschland. Eine umfassende Analyse der Hist
 orie und der Ursachen einer der weitreichendsten Fehlentwicklungen im Bere
 ich der IT-Sicherheit der letzten Jahre\, die sich in weit mehr zeigt\, al
 s nur in schlechter Prüfung der Anwesenheit von Gesundheitskarten im Gesun
 dheitswesen.\nZum letzten Chaos Communication Congress konnten Martin Tsch
 irsich und Bianca Kastl eine Ansammlung größerer und kleiner Sicherheitspr
 obleme in der elektronischen Patientenakte für alle aufzuzeigen – sei es i
 n der Ausgabe von Identifikationsmitteln\, in Systemen in der Telematikinf
 rastruktur oder in angebundenen Systemen. All diese Probleme kumulierten i
 n einem veränderten und reduzierten Rollout der ePA für alle in den Modell
 regionen Anfang 2025\, bei dem bereits erste Maßnahmen zur Schadensminimie
 rung unternommen wurden. \nEnde April 2025 wurde die ePA für alle dann auc
 h wirklich für alle deutschlandweit bereitgestellt – allerdings traten am 
 gleichen Tag die scheinbar sicher gelösten Sicherheitslücken im Zugangsman
 agement wieder zu Tage und wurden alsbald wieder nur provisorisch abgedich
 tet.\n\nDieser Talk will etwas zurückblicken auf die Geschichte und die Ur
 sachen dieser Sicherheitsprobleme der ePA für alle. Als «eines der größten
  IT-Projekte der Bundesrepublik» steht die ePA sinnbildlich für den digita
 lpolitischen Umgang mit Sicherheitsversprechen und interessensgetriebenen 
 Anforderungen über die Köpfe von Patient*innen oder Bürger*innen hinweg.\n
 \nDabei geht es nicht nur um technische Probleme und deren Behebungsversuc
 he\, sondern auch um die strukturellen Ursachen\, die große digitale Vorha
 ben immer wieder in manchen Bereichen scheitern lassen. Diese tiefergehend
 e Betrachtung kann uns dabei helfen\, die Ursachen für schlechte IT-Sicher
 heit auch bei zukünftigen digitalpolitischen Vorhaben in Deutschland besse
 r zu verstehen. Nicht für die ePA für alle und Anwendungen im Bereich der 
 Telematikinfrastruktur\, sondern auch weit darüber hinaus.\n\nTiefergehend

DESCRIPTION:Agentic AI is the catch-all term for AI-enabled systems that pr
 opose to complete more or less complex tasks on their own\, without stoppi
 ng to ask permission or consent. What could go wrong? These systems are be
 ing integrated directly into operating systems and applications\, like web
  browsers. This move represents a fundamental paradigm shift\, transformin
 g them from relatively neutral resource managers into an active\, goal-ori
 ented infrastructure ultimately controlled by the companies that develop t
 hese systems\, not by users or application developers. Systems like Micros
 oft's "Recall\," which create a comprehensive "photographic memory" of all
  user activity\, are marketed as productivity enhancers\, but they functio
 n as OS-level surveillance and create significant privacy vulnerabilities.
  In the case of Recall\, we’re talking about a centralized\, high-value ta
 rget for attackers that poses an existential threat to the privacy guarant
 ees of meticulously engineered applications like Signal. This shift also f
 undamentally undermines personal agency\, replacing individual choice and 
 discovery with automated\, opaque recommendations that can obscure commerc
 ial interests and erode individual autonomy.\n\nThis talk will review the 
 immediate and serious danger that the rush to shove agents into our device
 s and digital lives poses to our fundamental right to privacy and our capa
 city for genuine personal agency. Drawing from Signal's analysis\, it move
 s beyond outlining the problem to also present a "tourniquet" solution: lo
 oking at what we need to do *now* to ensure that privacy at the applicatio
 n layer isn’t eliminated\, and what the hacker community can do to help. W
 e will outline a path for ensuring developer agency\, granular user contro
 l\, radical transparency\, and the role of adversarial research.\nThe talk
  will provide a critical technical and political economy analysis of the n
 ew privacy crisis emerging from OS and application level AI agents\, aimed
  at the 39C3 "Ethics\, Society & Politics" audience.\n\n1. Defining the Th
 reat: The OS as a Proactive Participant (5 mins)\n   We will begin by defi
 ning "Agentic AI" in two contexts - imbibed into the operating system and 
 deployed via critical gateway applications such as web browsers. Tradition
 ally\, the operating systems and browsers are largely neutral enforcers of
  user agency\, managing resources and providing APIs for applications to r
 un reliably. We will argue that this neutrality is close to being eliminat
 ed. The new paradigm shifts these applications into a proactive agent that
  actively observes\, records\, and anticipates user actions across all app
 lications.The prime example for this analysis will be Microsoft’s "Recall"
  feature\, Google’s Magic Cue\, and OpenAI’s Atlas. Politically\, we will 
 frame this not as a "feature" but as the implementation of pervasive\, non
 -consensual surveillance and remote-control infrastructure. This "photogra
 phic memory" of and demand for non-differentiated access to everything fro
 m private Signal messages to financial data to health data creates a catas
 trophic single point of failure\, making a single security breach an exist
 ential threat to a user's entire digital life. Ultimately\, we hope to ill
 ustrate how putting our brains in a jar (with agentic systems) is effectiv
 ely a prompt injection attack against our own humanity.\n\n2. The Existent
 ial Threat to Application-Level Privacy (10 mins)\n   The core of the talk
  will focus on what this means for privacy-first applications like Signal.
  We will explain the "blood-brain barrier" analogy: secure apps are meticu
 lously engineered to minimize data and protect communications\, relying on
  the OS to be a stable\, neutral foundation on which to build. This new OS
  trend breaks that barrier. We will demonstrate how OS-level surveillance 
 renders application-level privacy features\, including end-to-end encrypti
 on\, effectively useless. If the OS can screenshot a message before it's e
 ncrypted or after it's decrypted\, the promise of privacy is broken\, rega
 rdless of the app's design. We will also discuss the unsustainable "clever
  hacks" (like Signal using a DRM feature) that developers are forced to im
 plement\, underscoring the need for a structural solution.\n\n3. An Action
 able Framework for Remediation (20 mins)\n   The final\, and most importan
 t\, part of the talk will move from critique to action. We will present an
  actionable four-point framework as a "tourniquet" to address these immedi
 ate dangers:\n\na. Empower Developers: Demand clear\, officially supported
  APIs for developers to designate individual applications as "sensitive" w
 ith the default posture being for such applications being opted-out of acc
 ess by agentic systems (either OS or application based) (default opt-out)\
 n\nb. Granular User Control: Move beyond all-or-nothing permissions. Users
  must have explicit\, fine-grained control to grant or deny AI access on a
 n app-by-app basis.\n\nc. Mandate Radical Transparency: OS vendors and app
 lication developers must clearly disclose what data is accessed\, how it's
  used\, and how it's protected—in human-readable terms\, not buried in leg
 alese. Laws and regulations must play an essential role but we cannot just
  wait for them to be enforced\, or it will be too late.\n\nd. Encourage an
 d Protect Adversarial Research: We will conclude by reinforcing the need f
 or a pro-privacy\, pro-security architecture by default\, looking at the l
 egal frameworks that govern these processes and why they need to be enforc
 ed\, and finally asking the attendees to continue exposing vulnerabilities
  in such systems. It was only due to technically-grounded collective outra
 ge that Recall was re-architected by Microsoft and we will need that energ
 y if we are to win this war.\n

 gic" which\, more often than not\, ended up being a court-approved "defeat
  device".\n\nWhat started as a "curious investigation" in 2015 to obtain a
  ground truth to widespread media reports of "VW being caught for cheating
 " ended up as a full-blown journey through the then-current state of the D
 iesel car industry.\n\nIn this talk\, Karsten and Felix will walk through 
 the different implementation of defeat devices\, their impact on emissions
 \, and the challenges in documenting seemingly black boxes in court-proven
  expert reports.\n10 years ago\, Felix spent a lot of sleepless nights on 
 reverse-engineering the Diesel software that implemented the (by now) well
 -known "Acoustic Function" defeat device\; he presented my findings at the
  32c3 and 33c3 in 2015 and 2016\, expecting this to be the last time we ne
 eded to hear about this.\n\nLittle did he know about the extent of the Die
 sel emissions cheating. Since then he has analyzed many more vehicles\, le
 arned a bit or two about mechanical engineering problems of cars.\n\nKarst
 en\, working as a court-appraised expert\, will add his unique view on the
  challenges in documenting software that was never meant to be understood 
 by the public.\n\nThis talk will discuss methodologies of independent anal
 ysis of highly dynamic systems that many people see as black boxes (but th
 at\, of course\, are not: they are just machines running software).\n

DESCRIPTION:Last year at 38c3\, we gave a talk titled "Ten Years of Rowhamm
 er: A Retrospect (and Path to the Future)."\nIn this talk\, we summarized 
 10 years of Rowhammer research and highlighted gaps in our understanding.\
 nFor instance\, although nearly all DRAM generations from DDR3 to DDR5 are
  vulnerable to the Rowhammer effect\, we still do not know its real-world 
 prevalence.\nFor that reason\, we invited everyone at 38c3 last year to pa
 rticipate in our large-scale Rowhammer prevalence study.\nIn this year's t
 alk\, we will first provide an update on Rowhammer research and present ou
 r results from that study. \n\nA lot has happened in Rowhammer research in
  2025.\nWe have evidence that DDR5 is as vulnerable to Rowhammer as previo
 us generations.\nOther research shows that not only can adversaries target
  rows\, but columns can also be addressed and used for bit flips.\nBrowser
 -based Rowhammer attacks are back on the table with Posthammer and with EC
 C. fail\, we can mount Rowhammer attacks on DDR4 with ECC memory.\n\nIn ou
 r large-scale study\, we measure Rowhammer prevalence in a fully automated
  cross-platform framework\, FlippyR.AM\, using the available state-of-the-
 art software-based DRAM and Rowhammer tools.\nOur framework automatically 
 gathers information about the DRAM and uses 5 tools to reverse-engineer th
 e DRAM addressing functions\, and based on the reverse-engineered function
 s\, uses 7 tools to mount Rowhammer.\nWe distributed the framework online 
 and via USB thumb drives to thousands of participants from December 30\, 2
 024\, to June 30\, 2025. Overall\, we collected 1006 datasets from 822 sys
 tems with various CPUs\, DRAM generations\, and vendors.\nOur study reveal
 s that out of 1006 datasets\, 453 (371 of the 822 unique systems) succeede
 d in the first stage of reverse-engineering the DRAM addressing functions\
 , indicating that successfully and reliably recovering DRAM addressing fun
 ctions remains a significant open problem.\nIn the second stage\, 126 (12.
 5 % of all datasets) exhibited bit flips in our fully automated Rowhammer 
 attacks.\nOur results show that fully automated\, i.e.\, weaponizable\, Ro
 whammer attacks work on a lower share of systems than FPGA-based and lab e
 xperiments indicated\, but at 12.5%\, are still a practical vector for thr
 eat actors.\nFurthermore\, our results highlight that the two most pressin
 g research challenges around Rowhammer exploitability are more reliable re
 verse-engineering tools for DRAM addressing functions\, as 50 % of dataset
 s without bit flips failed in the DRAM reverse-engineering stage\, and rel
 iable Rowhammer attacks across diverse processor microarchitectures\, as o
 nly 12.5 % of datasets contained bit flips.\nAddressing each of these chal
 lenges could double the number of systems susceptible to Rowhammer and mak
 e Rowhammer a more pressing threat in real-world scenarios.\nThis will be 
 a followup talk after our talk "Ten Years of Rowhammer: A Retrospect (and 
 Path to the Future)" at 38C3.\nIn the talk last year we gave an overview o
 f the current state of Rowhammer and highlighted that there are no large-s
 cale prevalence studies.\nWe wanted to change that and asked the audience 
 to participate in our large-scale study on Rowhammer prevalence.\n\nWe per
 formed the large-scale study on Rowhammer prevalence thanks to many volunt
 eers supporting our study by measuring their systems.\nIn total\, we colle
 cted 1006 datasets on 822 different systems (some systems were measured mu
 ltiple times).\nWe show that 126 of them (12.5%) are affected by Rowhammer
  with our fully-automated setup.\nThis should be seen as a lower bound\, s
 ince the preconditions required for effective tools failed on ~50% of the 
 systems.\nAmong many other insights\, we learned that the fully-automated 
 reverse-engineering of DRAM addressing functions is still an open problem 
 and we assume the actual number of affected systems to be higher as the 12
 .5% we measured in our study.\n\nNow\, one year after our talk at the 38C3
 \, we want to give an update on the current state of Rowhammer\, since mul
 tiple new insights were published in the last year:\nThe first reliable Ro
 whammer exploit on DDR5\, a JavaScript implementation of Rowhammer that wo
 rks on current DDR4 systems\, and an ECC bypass on DDR4\, just to name a f
 ew.\nAdditionally\, we want to present the results of our large-scale stud
 y on Rowhammer prevalence which was supported by the audience from last ye
 ar's talk.\n

DESCRIPTION:When building privacy-sensitive applications\, we often rely on
  proxies like Tor to ensure that no direct connections escape the intended
  anonymity network. However\, verifying that every part of an application 
 reliably goes through the proxy is surprisingly difficult. Even a single s
 yscall escaping the proxy path can quietly deanonymize a user.\n\nSocksTra
 ce is a lightweight proxy-leak detection tool that traces network-related 
 syscalls and validates whether they correctly route through the configured
  proxy.\n\nIn this talk\, I’ll show how SocksTrace works under the hood\, 
 what kinds of leaks it can catch\, and why syscall-level inspection is ess
 ential for high-assurance privacy tools. I’ll also walk through real-world
  findings: during our testing\, we identified previously unknown proxy lea
 ks in major browsers including Firefox and Brave\, one of which resulted i
 n a confirmed bug bounty. These results highlight how subtle proxy routing
  mistakes can occur even in widely-used\, privacy-oriented software.\nSock
 sTrace is a Linux-based proxy leak detector and traffic proxifier built on
  seccomp-notify. By intercepting network syscalls directly in the kernel\,
  it provides runtime-agnostic visibility and enforcement that works even f
 or statically linked binaries and modern browsers.\n\nThe talk showcases r
 eal WebRTC-related proxy leaks discovered using SocksTrace\, explains shor
 tcomings of traditional tools\, and demonstrates transparent SOCKSificatio
 n\, DNS enforcement\, and safe handling of applications that launch their 
 own Tor instances. We conclude with practical use cases and future directi
 ons for syscall-level network containment.\n

DESCRIPTION:The Internet is decentralized by design. It came into being not
  at once\, but in parts.  New protocols were added on top of  previous one
 s\, with each new protocol extending and improving functionality of the gl
 obal network. However one essential protocol is still missing  —  an open 
 way to discover and publish content on the global web.\nI have implemented
  a conceptual decentralized content sydication platform and would like to 
 tell more about the philosophy behind it.\n\nThe workshop will consist of 
 two parts: 30 min presentation about the concept and 30 min workshop where
  participants would try to publish their social post on RSDS network.\n

DESCRIPTION:Quantum computers represent a looming threat to much of the cri
 tical foundations of modern cryptography. Post-quantum cryptography (PQC) 
 utilizes hard mathematical problems that we believe resist the so-called "
 quantum advantage\," to preserve security and privacy. In this workshop we
  will unpack the principles behind the leading PQC families such as lattic
 e and code based constructions\, then showcase their implications for cryp
 tocurrencies\, digital signatures\, and zero-knowledge protocols.\n

DESCRIPTION:[be-BOP](https://be-bop.io/) is free and open-source software f
 or **autonomous commerce**. It’s an all-in-one\, batteries-included soluti
 on built for merchants\, not engineers. It lets communities run markets wi
 thout accounts\, tracking\, or gatekeepers. From shops to restaurants\, ti
 cketing to peer-funding — all self-hosted. Adoption grows among merchants 
 and creators seeking real independence.\n\nNext steps: **multitenant** for
  specialization\, **cross be-BOP** for **federation**. We’re building the 
 foundations of a free\, federated economy.\n**be-BOP is free and open-sour
 ce software for sovereign commerce.**\n\nIt’s built on a simple belief: me
 rchants and communities should own the tools they depend on. We design tec
 hnology that respects privacy\, rejects dark patterns\, and removes the ne
 ed for accounts or intermediaries. Our vision is trade without platforms\,
  data brokers\, or gatekeepers — commerce as a public good\, not a private
  empire.\n\nUnlike fragmented “self-commerce” tools\, **be-BOP is a comple
 te\, batteries-included stack**. It supports e-commerce\, point-of-sale\, 
 restaurant systems\, ticketing\, peer-funding\, and subscriptions — all se
 lf-hosted\, interoperable\, and designed for real-world merchants. It aims
  for the reliability of a platform\, without the capture of one.\n\nAdopti
 on grows from the edges: merchants and cooperatives seeking independence\,
  and creators tired of surrendering revenue to platforms. In **Goma**\, co
 mmunities use be-BOP to organize resources and stabilize local economies u
 nder pressure. Elsewhere\, artists use it to sustain open culture without 
 permission or lock-in.\n\nThe roadmap pushes beyond software. **Multitenan
 t be-BOP** will enable domain-specific ecosystems — tailor-made for farmer
 s’ markets\, repair collectives\, or independent venues — while **cross be
 -BOP** will link autonomous nodes into a federation of mutual visibility. 
 Together they answer the twin failures of centralized commerce: loss of ag
 ency and isolation.\n\nbe-BOP aspires to be more than a toolchain. It’s an
  experiment in rebuilding economic infrastructure on open terms — a founda
 tion for **free\, federated\, and sustainable digital economies** that can
 ’t be quietly “enshittified.”\n

DESCRIPTION:A collaborative dialogue to examine and unsettle the philosophi
 cal foundations of decentralization. What do we actually mean when we spea
 k of decentralization\, and what forms of order\, asymmetry or coordinatio
 n quietly sustain it? Where does decentralization end and centralization b
 egin\, and is this opposition as clear as it appears? Beyond familiar bina
 ries such as order and chaos\, what assumptions are embedded in the formal
  systems\, protocols and narratives we rely on? What do participants exper
 ience when engaging with institutions\, infrastructures or rulesets\, and 
 what recedes into the background as those systems operate? Through a self-
 reflective and performative inquiry\, this dialogue explores decentralizat
 ion not as a moral absolute but as a situated and contested design space s
 haped as much by what it excludes as by what it enables.\nIn its iterative
 \, by now familiar format\, the workshop opens with a short framing by the
  facilitator\, introducing the inquiry and reflecting on the asymmetry of 
 facilitation itself and its relevance to decentralization. Participants th
 en break into smaller groups to explore the questions raised\, with room f
 or divergence\, contestation and parallel lines of inquiry. The format rem
 ains intentionally open to shifts in attention\, authority and coordinatio
 n as the session unfolds. We reconvene toward the end to share reflections
 \, tensions and unresolved questions rather than to converge on a single c
 onclusion. The workshop invites participants to engage not only with ideas
  of decentralization but with how those ideas are enacted\, sustained or r
 esisted in practice.\n

DESCRIPTION:Build your own solar powerd Lora node\nAfter three days of conf
 erence and talks\, what better ways to wind out the day than to get togeth
 er in a relaxed atmosphere and try to build some hardware?\n\nThis worksho
 p is intended for beginners who want to learn how to build their own lora/
 meshtastic/meshcore/reticulum hardware. These little devices can be used t
 o message each other and build a network utilizing only some small antenna
 s without the need of internet or a phone network. Together\, we will buil
 d our own solar powered outside LORA nodes that can be used with mesh soft
 ware such as Meshtastic\, Meshcore or Reticulum without the need of a powe
 r outlet. We will bring the required parts and an easy to follow "how to" 
 manual. There will be little to no input but we want to create a cozy atmo
 sphere to come together to learn\, to solder and teach ourselfs how to cre
 ate our own communication devices from scratch (well at least almost). We 
 will start at 23:00\, feel free to stay until you are done or finish in on
  your own time.\n\nEach node will consist of a solar panel\, a low power l
 ora node (XIAO nRF52840 & Wio-SX1262 Kit)\, batteries\, an antenna + other
  connecting components such as cables and a charging controller to make ev
 erything work together nicely. We have tried to keep the cost as low as po
 ssible so we used the cheapest components we found\, for long term use you
  might want to upgrade some components.\n\nThere will be only a limited am
 ount of seats available. Please come to the hardware hacking area one hour
  (22:00) before this workshop starts to get the hardware (35€\, cash prefe
 rred). This workshop is intended for beginners in Lora hardware and hardwa
 re hacking. Some previous soldering experience is helpful but not required
 .\n\nHow to guide: https://cryptpad.fr/code/#/2/code/view/u1VaqnWs0jvLT6qR

DESCRIPTION:Join us as we hack at a popular children's smartwatch and expos

  on the subway and sold by your cell provider\, manufacturers are charging
  premium prices comparable to an entry-level Apple watch.\n\nIn exchange\,
  parents are promised peace of mind: A safe\, gentle introduction into the

 ular children's watches out there\, from gaining initial access to running
  our own code on the watch. Along the way\, we find critical security issu
 es at every turn. Our PoC attacks allow us to read and write messages\, vi

DESCRIPTION:The Tegra X2 is an SoC used in devices such as the Magic Leap O
 ne\, and Tesla's Autopilot 2 & 2.5 promising a secure bootchain. But how s
 ecure really is the secure boot? In this talk I go over how I went from a 
 secured Magic Leap One headset\, to exploiting the bootloader over USB\, t
 o doing fault injection to dump the BootROM\, to finding and exploiting an
  unpatchable vulnerability in the BootROM's USB recovery mode affecting al
 l Tegra X2s.\nIn mid 2024\, a friend approached me about Magic Leap making
  their TX2 based XR headsets little more than a paperweight by disabling t
 he mandatory activation servers. I morally dislike this\, companies should
 n't turn functional devices into e-waste just because they want to sell ne
 wer devices.\n\nAfter obtaining one\, and poking at the Fastboot implement
 ation\, I discovered it was based off NVIDIA's Fastboot implementation\, w
 hich is source available. I found a vulnerability in the NVIDIA provided s
 ource code in how it unpacks SparseFS images (named sparsehax)\, and succe
 ssfully blindly exploited the modified implementation on the Magic Leap On
 e. I also found a vulnerability in it that allowed gaining persistence via
  how it loads the kernel DTB (named dtbhax).\n\nStill unsatisfied with thi
 s\, I used fault injection to dump the BootROM from a Tegra X2 devkit.\n\n
 In the BootROM I discovered a vulnerability in the USB recovery mode. Expl
 oiting this vulnerability proved difficult due to only having access to me
 mory from the perspective of the USB controller. I will explain what was t
 ried\, why it didn't work\, and how I eventually got code execution at the
  highest privilege level via it.\n\nAs I will demonstrate\, this exploit a
 lso functions on Tesla's autopilot hardware.\n

DESCRIPTION:Science is hard and research into the usage of the Tor network 
 is especially so. Since it was designed to counter suveillance\, it gather
 ing reliable information is difficult. As a consequence\, the studies we d
 o have\, have yielded very different results.\n\nThis talk investigates th
 e root causes of contradicting studies by highlighting how slight changes 
 in methodology or data selection completely change the results and thereby
  our understanding of what the Darknet is. Whether you consider it the las
 t bastion of freedom or a haven of crime\, this talk will tell you where t
 o look and what to ignore in order to confirm your current opinion. And in
  case you are open to changing it\, we have some food for thought for you.
 \nOnion services can be considered one of the most controversial aspects o
 f the Tor network\, because they allow the anonymous hosting of services\,
  which has enabled the creation of illegal services which are difficult fo
 r law enforcement to shut down. Defenders argue that this is a price worth
  paying to ensure free speech for people who could otherwise not speak up 
 or run their own services.\n\nThis obviously raises the question what onio
 n services are being actually used for in practice. Many researchers have 
 tried to answer this question in the past. Based on their work we already 
 know a few things:\n\n- 9% of all Websites on the Darknet are marketplaces
  [1]\n- 2.7% of all Websites on the Darknet are marketplaces [2]\n- 50% of
  all Websites on the Darknet are marketplaces [3]\n- 8.4% of all Websites 
 on the Darknet are marketplaces [4]\n- 27% of all Websites on the Darknet 
 are marketplaces [5]\n- 34.8% of all Websites on the Darknet are marketpla
 ces [6]\n\nNo\, this is not a copy and paste error\, all of the above stat
 ements can be found in peer-reviewed scientific publications. All of these
  results are valid on their own and constitute valuable contributions to s
 cience\, but it does not take an expert to notice the contradictions in th
 eir findings.  \nThe reasons for these inconsistencies are the main topic 
 of this talk. We will discuss the information available to researchers and
  the limitations originating from it. Challenges and current disagreements
  when it comes to interpreting available data will be addressed along with
  common misrepresentations of research results. We will highlight how the 
 choice of data sources can predetermine the final result before a study ha
 s even begun\, how minor changes to definitions can lead to completely dif
 ferent results and how important context is when interpreting data.\n\nArm
 ed with this knowledge\, we can tackle the challenge to find out what we k
 now about the Darknet\, what we might figure out in the future\, what we c
 an reasonably assume but will never be able to prove\, and what we will (h
 opefully) never know.\n\n-----------------------------------------\nSource

DESCRIPTION:The Dutch railways have been operating an increasingly complica
 ted network of trains for over 80 years. The task of overseeing it is far 
 too complex for a single human. As such\, a network of specifically scoped
  humans has been connected. Over time\, computers and software have been i
 ntroduced into the system\, but today there is still a significant role fo
 r humans.\n\nThis talk describes the network of "human microservices" that
  is involved in the Dutch Railways' day to day operation from the eyes of 
 a software developer.\nWhen a train breaks down in the Netherlands\, a sys
 tem of interconnected humans is shifted into gear. The current state of th
 at system has been developed for over 80 years and as such should be seen 
 as an architectural marvel. Even though there is nowadays a significant am
 ount of software involved in the process\, the people involved are still v
 ery much necessary.\n\nThis talk describes the processes and roles involve
 d in the Dutch railway day to day operations. We will start at a broken do
 wn train on a busy track and work our way towards solutions including drag
 ging the train\, evacuating travelers and redirecting other trains on that
  trajectory. We will explore this from a software developer's perspective.
  We will consider the people involved as an ancient form of hardware\, and
  the protocols between them as software. We will also go over the more mod
 ern additions to the system: phone lines and software running on actual co
 mputers.\n\nAfter our investigation you will have a new understanding of t
 he complexity of running a railway network. And we will ask ourselves: is 
 this an outdated system that needs to be digitized? Or is this actually a 
 modern system with microservices and a "human in the loop"?\n

DESCRIPTION:Transient execution CPU vulnerabilities\, like Spectre\, have b
 een making headlines since 2018. However\, their most common critique is t
 hat these types of vulnerabilities are not really practical. Even though i
 t is cool to leak `/etc/shadow` with a CPU bug\, it has limited real-world
  impact. In this talk\, we take Spectre out for a walk and let it see the 
 clouds\, by leaking memory across virtual machine boundaries at a public c
 loud provider\, bypassing mitigations against these types of attacks. Our 
 report was awarded with a $151\,515 bug bounty\, Google Cloud's highest bo
 unty yet.\nSeven years ago\, Spectre and Meltdown were announced. These tw
 o vulnerabilities showed that instructions executed by the CPU might accid
 entally access secret data. This secret data can contain files cached from
  disk\, cryptographic keys\, private information\, or anything else that m
 ight be stored in memory. An attacker can use Spectre to learn the value o
 f that secret data\, even though the attacker is not supposed to have acce
 ss to it.\n\nEven though this sounds problematic\, there is a reason why t
 hese type of vulnerabilities haven't had a significant real-world impact. 
 Mitigations make it much harder to pull off\, and an attacker needs a form
  of remote code execution anyway to trigger the relevant CPU instructions.
  If an attacker can already execute arbitrary code\, then Spectre is proba
 bly not what you should be worried about. For regular users\, these CPU vu
 lnerabilities are likely not that much of a threat.\n\nHowever\, that is n
 ot the case for public cloud providers. Their business model is to provide
  *remote code execution as a service*\, and to rent out shared hardware re
 sources as efficiently as possible. Customers run their system in an seemi
 ngly isolated virtual machine on top of shared physical hardware. Because 
 customers can run anything they want on these systems\, public cloud provi
 ders must treat these workloads as untrusted. They have to assume the wors
 t case scenario\, i.e. that an attacker is deliberately trying violate the
  confidentiality\, integrity or availability of their systems\, and\, by e
 xtension\, their customers' systems. For transient execution vulnerabiliti
 es like Spectre\, that means that they enable all reasonable mitigations\,
  and some more.\n\nIn this talk\, we show that transient execution attacks
  can be used on real-world systems\, despite the deployed software mitigat
 ions. We demonstrate this by silently leaking secret data from another vir
 tual machine at a major global cloud provider\, defeating virtual machine 
 isolation without leaving a trace. Additionally\, we'll discuss our coordi
 nated disclosure process\, the currently deployed mitigations and how futu
 re mitigations could address the issue.\n

DESCRIPTION:**39C3 LED badge -- SMD for Beginners**  \n\nThe 39C3 LED badge
  contains 42 LEDs that blink under control of of a pre-programmed 4 cent m
 icrocontroller. When the badge is alone\, the LEDs will blink randomly. Wh
 en it is among friends (when there are other badges nearby)\, it will disp
 lay a chaser pattern. \n\nIn this workshop you will learn how to solder Su
 rface Mounted Devices using a normal soldering iron.\n\nSuitable for begin
 ners. Under 16s only with responsible adult supervision.\n### 39C3 LED bad
 ge -- SMD for Beginners\n\n![39C3 LED badge](https://usercontent.events.cc
 c.de/congress/2025/hub/usercontent/b/7dccaedbb7ec/39C3badge.png)\n\nSurfac
 e Mounted Devices (SMDs) are small compared to Through Hole (TH) electroni
 c components\, and have the reputation of being difficult to work with as 
 a hobyist: Difficult to see and handle\, when you sneeze\, you loose them 
 and you can not easily use them on 2.54mm raster prototyping boards.\n\nSM
 D components are designed to be used in a reflow soldering process where t
 iny dots of solder paste are applied to a Printed Circuit Board (PCB)\, af
 ter which the SMD components are "Picked and Placed" on the PCB\, after wh
 ich the whole PCB is heated to the melting point of the solder ("reflowing
 ")\, actually completing the  electrical connections.\n\nThis workshop is 
 aimed at showing you that the reputation of being difficult to work with i
 s a bit undeserved\, and that you can also work with SMDs using just a  re
 gular soldering iron: With some simple tricks and a suitable selection of 
 components (not the smallest possible)\, the vast majority of people can s
 uccessfully complete this project.\n\nBeing able to solder SMD projects us
 ing just a simple soldering iron will also help you develop some skills th
 at are useful if you  need to do "rework" on reflow soldering projects. Re
 flow soldering is also not difficult to do as a hobbyist\, but requires a 
 few more tools like a stencil to apply solder paste and either an oven or 
 a hot plate to do the reflowing. It is\, however\, much quicker than solde
 ring the parts one by one\, and can yield more professional looking\, clea
 ner\, solder joints.\n\nThe project is an electronic name-badge - You shou
 ld write your name (or nick) on it and wear it. It contains 42 LEDs\, a mi
 crocontroller\, some support components and an InfraRed transmitter and re
 ceiver that allow it to communicate with other badges. When the badge dete
 cts the presence of other badges ("friends") nearby\, it will change its b
 ehaviour. It will not only interact with other 39C3 LED badges\, but also 
 with TBD badges - come visit the TBD assembly at komona or https://tbd.cam
 p\n\n![TBD badge](https://usercontent.events.ccc.de/congress/2025/hub/user
 content/e/d619de5f1be1/tbdbadge.png)\n\n### Costs\nThis workshop is donati
 on based. Materials costs are 2 euro per badge. Donations will go towards 
 1) covering costs of the badges\, 2) covering costs of running the hardwar
 e hacking area in general\, 3) covering costs of organizing TBD (see the T
 BD assembly at komona or https://tbd.camp)\n\n### Registration\nThe number
  of participants per session is limited. First come\, first served. Either
  get a participation voucher beforehand or show up early (there may be pla
 ces left).\nThere will be *numbered* paper vouchers available for each ses
 sion some time in advance of each session. If you get a voucher and do not
  show up *before* the designated starting time\, someone else may take you
 r spot. Please don't take multiple vouchers and don't take  vouchers if yo
 u don't actually plan to participate.\n\n### Getting a kit\nKits are part 
 of the workshop and not for sale separately. You can\, however easily sour

DESCRIPTION:Let's build mesh radios from scratch.We will bring 20 PCB kits\
 , containing all parts. Soldering is difficult but doable in the Congress.
  You have to be very proficient with soldering to get this done during Con
 gress\, but the Eternal Soldering Workshop is open and nearby.We also have
  solder paste and stencils for the real pros!If you don't want to get into
  soldering now\, you can take one of the kits home. During the workshop yo
 u will get to know everything necessary to get the job done.\n### Building
  Autonomy: Mesh Radio Hardware Workshop\n\nDecentralized communication inf
 rastructures require more than finished devices: understanding the hardwar
 e level enables critical engagement with proprietary designs and creates a
 utonomy beyond commercial dependencies. The workshop covers complete assem
 bly of an nRF52-based mesh node in Heltec form-factor\, where participants
  gain practical comprehension of decentralized radio network architecture 
 through soldering components\, integrating LoRa modules\, and installing f
 irmware. Critical decentralization means not merely using distributed netw
 orks but mastering their technical foundations: building custom boards rev
 eals trade-offs between energy efficiency\, range\, and cost\, enables des
 ign adaptation to specific requirements\, and develops capabilities for re
 pairing and modifying existing infrastructure. Control over hardware desig
 n and firmware variants dissolves dependence on manufacturer decisions and
  permits experimental topologies that commercial solutions cannot accommod
 ate. The workshop targets advanced participants with mesh operation experi
 ence\, as technical fundamentals are prerequisite knowledge.\n\n**Prerequi
 sites:** Operational experience with mesh nodes (advanced)  \n**Materials:
 ** PCB kits available\, pricing will be announced\n

DESCRIPTION:With re:luks your full disk encrypted (FDE) server can be reboo
 ted automatically - no need to manually enter the disk encryption passphra
 se.\nOne of the annoyances of full disk encryption (FDE) is that a reboot 
 (which might be necessary after system updates) requires the disk passphra
 se to be entered. re:luks solves this problem by using a second FDE server
  for mutal reboots. The solution follows the KISS principle and consists o
 f a short Python script.\n\nIf you want to keep your server up-to-date and
  don't want to sacrifice disk encryption or convenience\, then this short 
 project presentation might be for you! Let's increase the power cycle coun
 t of our FDE servers by automating the reboot process!\n\nSlides: https://

DESCRIPTION:\nHQ is an open-source stack for annotating data with the help 
 of LLMs. Using schemas written in natural language\, items such as news ar
 ticles or CSVs can be turned into dashboards that are easy to interpret\, 
 export\, and audit. The aim is to help researchers apply their analytical 
 frameworks to larger datasets with less effort. Because schemas are define
 d in natural language\, the approach is accessible even without programmin
 g skills\, giving many people a way to extract information directly.\n\nWh
 ether you are doing keyword labelling\, 1–10 rating scales\, or graph trip
 lets\, the goal is to make it easier to conduct research\, gather evidence
 \, or simply organise data. This applies whether you are working with thou
 sands of court documents\, news articles\, CSV datasets\, or photos of rec
 eipts.\n\nMore information and examples: \\\nhttps://github.com/open-polit
 ics/open-politics-hq \\\nhttps://docs.open-politics.org\n\nThe workshop wi
 ll focus on presenting existing analyses and developing new ones together.
  The objective is for participants to gain an understanding of the softwar
 e and the analytical possibilities it enables. We are also interested in h
 earing your feature wish-list and\, where appropriate\, incorporating it i
 nto the project roadmap.\n\nWe will conclude with an overview of our long-
 term vision\, including where the tool is headed and what the next develop
 ment steps will be.\n\nP.S.\nAlthough our project also involves extensive 
 research on validating and de-biasing LLM-generated labels\, this workshop
  will concentrate on the practical use of HQ. For methodological discussio
 ns about robustness\, please contact engage@open-politics.org\n

DESCRIPTION:The talk is about the ideas behind setting up the David Graeber
  Institute and the Museum of Care. The Survival Kit Collection brings toge
 ther collectives developing open source "social technologies" —spirulina f
 arms\, self-replicating 3D printers\, modular housing\, low-cost water sys
 tems\, and ... art and education. In 2019\, together with David Graeber\, 
 we held the first workshop about the Museum of Care at CCC to reimagine th
 e relation between freedom\, technology and value. Over these 6 years\, th
 e Museum of Care and the David Graeber Institute have experimented with va
 rious projects: the survival collection\, Visual Assembly\, and creating a
 n open space for horizontal knowledge production—something we hope to deve
 lop into an actual University.\nWe think humanity could already be living 
 in a society of abundance and communal luxury. We have the technologies to
  produce enough for everyone to have everything. The issue isn't technolog
 ical but social. This is why we need a Museum (of Care): museums are among
  the few places that create\, distribute\, and preserve what a society val
 ues.\n\nWhat will be at the session:\nWe'll tell in more detail about the 
 concept of the Museum of Care on abandoned ships (of which\, according to 
 Maritime Foundation data\, there are more than 4\,500 in the world). We'll
  talk about the halls of our museum: the Hall of Giants and other emerging
  spaces. Projects we're building—spirulina farms\, 3D printers—in Saint Vi
 ncent (Caribbean) and Kibera Art District\, Nairobi Kenya\, Playground des
 igned that communities can construct with nearly no resources. Can we actu
 ally build a nomadic museum proud not of its unique exhibits but of how ea
 sily they spread and get replicated?\n\nThen we will move to an open conve
 rsation about what poetic technologies are and how they differ from bureau
 cratic ones. Some people may have read David Graeber's book The Utopia of 
 Rules\; here you can download his other texts that are less widely known o
 r not yet published. We would very much like to explore the question of po
 etic and bureaucratic technologies together with you. To facilitate this d
 iscussion\, the David Graeber Institute has invited Alistair Parvin\, crea
 tor of the Wiki House project\, to join Nika Dubrovsky in conversation.\n\
 nThe discussion continues in the format of a Visual Assembly—focused on bu
 ilding a distributed\, non-hierarchical\, genuinely open University with d
 ifferent ideas of funding and knowledge production. This is the very begin
 ning of the process so all input is very much welcome. We'd welcome any id
 eas\, critiques\, or proposals for collaboration.\n

DESCRIPTION:"Wir gehen nach Karlsruhe!“ – das klang vor zehn Jahren nach Au
 fbruch und juristischem Hack. Heute ist klar: Strategische Prozessführung 
 ist kein Sprint\, sondern ein zähes\, manchmal frustrierendes Dauerprojekt
 .\n\nIn diesem Talk ziehen wir Bilanz: Was haben wir mit zivilgesellschaft
 lichen Verfassungsbeschwerden im Bereich Technologie erreicht – und wo sin
 d wir gescheitert? Welche Fehler würden wir heute vermeiden\, welche Wege 
 waren richtig? Und was bedeutet es\, wenn das höchste deutsche Gericht zun
 ehmend weniger Lust auf digitalpolitische Grundrechtsfragen zeigt?\n\nEin 
 realistischer Blick hinter die Kulissen strategischer Klagen – und die Fra
 ge: Wie hackt man das Rechtssystem im Jahr 2025?\nWenn Gesetze Grundrechte
  verletzen\, warum nicht das Bundesverfassungsgericht hacken – mit Strateg
 ie\, Teamwork und guter Begründung? Aus dieser Idee ist inzwischen ein zen
 trales Werkzeug zivilgesellschaftlicher Gegenmacht geworden: Strategische 
 Prozessführung. Das Prinzip ist einfach: Gesetze nicht nur kritisieren\, s
 ondern systematisch angreifen\, mit gezielten Verfassungsbeschwerden gegen
  Überwachung\, Zensur und staatliche Eingriffe in die digitale Freiheit.\n
 Seitdem hat sich viel getan. Organisationen wie die Gesellschaft für Freih
 eitsrechte (GFF) haben den Weg nach Karlsruhe professionalisiert und Verfa
 hren angestoßen\, die viele aus den Nachrichten kennen:\ngegen die Vorrats
 datenspeicherung\,\ngegen das BND-Gesetz zur Auslandsüberwachung\,\ngegen 
 den Einsatz von Palantir\,\nund gegen den Einsatz von Staatstrojanern.\nEi
 nige dieser Verfahren waren erfolgreich und haben Gesetze gekippt. Andere 
 sind krachend gescheitert – oder hängen seit Jahren in Karlsruhe fest. Dab
 ei zeigt sich: Der Weg zum Urteil wird härter\, die Erfolgsaussichten klei
 ner\, und das Verfassungsgericht ist nicht mehr der progressive Motor\, de
 r es mal war.\nDieser Talk zieht eine ehrliche Bilanz: Was bringt strategi
 sche Prozessführung wirklich? Was lässt sich aus Erfolgen und Misserfolgen
  lernen? Welche Fälle lohnen sich – und wo wird der Rechtsweg zur Sackgass
 e? Und wie verschiebt sich das Ganze inzwischen auf die europäische Ebene 
 – wo neue Schauplätze wie der Digital Services Act oder der AI Act warten?
 \nKeine juristische Vorlesung\, sondern ein Erfahrungsbericht aus zehn Jah
 ren digitaler Grundrechtsarbeit. Es geht um Taktik\, Fehlentscheidungen\, 
 unerwartete Allianzen – und um die Frage\, wie man auch heute noch im Rech
 tssystem rütteln kann\, wenn die Türen in Karlsruhe enger werden.\nDer Vor
 trag wird gehalten von Simone Ruf und Jürgen Bering von der Gesellschaft f

DESCRIPTION:The Vital Bracelet series is an ecosystem of interactive fitnes
 s toys\, content on memory chips\, and apps that talk via NFC. In this tal
 k\, we'll explore the hardware and software of the series\, from its obscu
 re CPU architecture\, to how it interacts with the outside world\, from du
 mping OTP ROMs and breaking security\, to making custom firmware.\nThe Vit
 al Bracelet series\, active from 2021 to 2024\, was a line of toys that re
 volved around a number of fitness bracelets that encouraged exercise by ra
 ising characters from the Digimon series\, and expanding into tokusatsu an
 d popular anime characters later. Think of it as Tamagotchi\, but nurturin
 g through exercise instead of button presses.\n\nIn this presentation\, we
 'll look at the different parts of this series' ecosystem\, how they work\
 , and the different ways to circumvent various security measures and custo
 mize the devices' behavior.\n\nWe start by looking at the first Vital Brac
 elet\, with a quick introduction to hardware reverse engineering and how t
 o dump firmware out of flash. Following that\, we will take a look at the 
 microcontroller used in the devices\, and its obscure instruction set arch
 itecture. This will lead into an exploration of how to reverse engineer co
 de when you are missing a significant portion of it\, and how the embedded
  ROM was dumped. After this\, we will look at the DRM applied to content\,
  and how it was circumvented. Next\, the device's NFC capabilities will be
  explored.\n\nWith the release of the Vital Bracelet BE\, which introduced
  upgradable firmware\, came new challenges and opportunities. We will take
  a look at the new content format and additional DRM measures it incorpora
 ted\, plus how the device's bootloader was dumped despite its signature ve
 rification scheme.\n\nFinally\, we will take a look at the process for mod
 ding the various Vital Bracelet releases\, and some techniques to use whil
 e writing patches.\n\nThe material in this talk can be applied beyond just
  the Vital Bracelet series\, and can be useful if you want to explore othe
 r electronic toys\, or just hardware reverse engineering in general.\n

DESCRIPTION:Over the last half year I have explored the Motorola mc14500 - 
 a CPU with a true one-bit architecture - and made it simulate Conway's Gam
 e of Life. This talk gives a look into how implementing a design for such 
 a simplistic CPU can work\, and how it's possible to address 256 LEDs and 
 half a kiloword of memory with just four bits of address space.\nIn the la
 te seventies\, Motorola created a very cheap CPU\, intended to replace log
 ic circuits made from electromechanical relays. The resulting IC is so min
 imalistic that it can hardly be recognized as a CPU: Its data bus is just 
 a single bit wide\, it has no program counter\, and the address bus isn't 
 connected to the cpu at all. Yet\, with just a few support components\, an
 d some clever programming\, it can be made to do all sorts of things.\n\nW
 e'll explore hardware design and programming by taking a look at my implem
 entation of Conway's Game of Life\, and answer the question of how one can
  address 512 words of memory\, as well as some other peripherals\, using j
 ust four bits of address space.\n\nOutline:\n* History and theory of opera

DESCRIPTION:2025 was a bad year for South Korean mobile network operators. 
 All three operators (SK Telecom\, KT\, LG U+) were affected by breach in s
 ome part of their respective network: HSS of SK Telecom\, femtocells of KT
 . Meanwhile\, handling of the breach by each operators and post-mortem ana
 lysis of each breaches have stark differences. The technical details and i
 mplemented mitigations are often buried under the vague terms\, and occasi
 onally got lost in translation to English. In this talk\, I will cover the
  technical aspects of SK Telecom and KT's breach\, and how the operators a
 re coping to the breach and what kind of measurements have been performed 
 to secure their network.\nThis talk will cover the public information and 
 experiments related to the South Korean telco breaches in 2025. This talk 
 will cover SK Telecom's HSS breach (final results announced)\, KT's femtoc
 ell breach (investigation ongoing) and related operator billing fraud\, an
 d revisit Phrack report on KT and LG U+ breach. We also give a light on th
 e detail regarding the implemented mitigation and diaster response of each
  operators.\n\nSK Telecom's HSS breach is attributed to a variant of BPFDo
 or malware\, resulting leakage of critical operator data related to subscr
 iber authentication and accounting. They replaced the SIM cards of all 23 
 million subscribers\, and implemented additional mechanism to track the po
 ssible cloning of the SIM card. We analyze the aftermath and how it will e
 ffectively protect against the said attack.\n\nKT's femtocell and operator
  billing breach (investigation still ongoing as the time of writing) is at
 tributed to the mismanagement of KT's femtocell\, allowing an external att
 acker to mimick the behavior of KT's legitimate femtocell and use as a cel
 lular interception device. This is a modern implementation of the remarkab
 le research "Weaponizing Femtocells" back in 2012\, and new cellular techn
 ologies like VoLTE have changed the possible attack vectors. We provide a 
 possible theory on how the attack would be possible\, based on the publicl
 y available information and previous researches.\n\nFinally\, we also cove
 r the characteristics of South Korean mobile market and how the media caus
 ed the inaccurate analysis and FUD (fear\, uncertainty\, and doubt). In pa
 rticular\, how SMS-based 2FA is tied to personal authentication and how ev
 erything is strongly bound to the personal identity. Early media reports c
 ould be attributed to the information "lost in translation" and inaccurate
  information in English-language articles when the details of the breach w
 ere not widely shared. We try to correct the information (also in the offi
 cial incidence report) and showcase how not to report the breach in genera
 l.\n

DESCRIPTION:The virus of surveillance is spreading across the European Unio
 n. In the form of its "ProtectEU" Internal Security Strategy\, the Europea
 n Commission is planning to attack encryption\, re-introduce mandatory dat
 a retention and strengthen Europol and Frontex\, the main agents of its op
 pressive law enforcement infrastructure. In this talk\, we will journey th
 e wastelands of the EU surveillance apocalypse together: We will take a cl
 ose look at what politicians are planning to undermine our fundamental rig
 hts\, the technology involved\, and the real harms we must fight. From the
 re\, we will chart pathways to resistance and collective immunity against 
 a surveillance agenda that requires us to form new alliances and re-think 
 mobilization.\nAdmidst its current push to remove the rules that have prot
 ected the EU's environment\, consumer and fundamental rights\, there is on
 e area the European Commission happily calls for more regulation: Internal
  security. The recent "ProtectEU" Internal Security Strategy does little t
 o protect Europeans\, and instead foresees attacks on encryption\, the re-
 introduction of mandatory data retention and the strengthening of Europol 
 and Frontex\, the main agents of the EU's oppressive law enforcement infra
 structure. In this talk\, we will introduce the strategy and its main pill
 ars\, explain its political and legal contexts\, and take a look at what i
 t would mean for our fundamental rights\, access to encryption\, and IT se
 curity if enacted. But not all hope is lost (yet)\, and together we want t
 o chart pathways to meaningful resistance. To do so\, we will help underst
 and the maze of the EU's lawmaking process and identify pressure points. W
 e will then look back at past fights\, lessons learned and new opportuniti
 es to act in solidarity against a surveillance agenda that is truly apocal
 yptic.\n

DESCRIPTION:Auch in der Schweizer Netzpolitik ging es im auslaufenden Jahr 
 drunter und drüber. Wir blicken mit gewohntem Schalk auf das netzpolitisch
 e Jahr 2025 zwischen Bodensee und Matterhorn zurück - und diskutieren jene
  Themen\, die relevant waren und relevant bleiben.\n**Themen sind unter an
 derem:**\n\n\n**E-ID und E-Collecting:** Die netzpolitische Community hat 
 nicht nur eine privatisierte E-ID verhindert sondern auch den Datenschutz 
 als zentrales Prinzip verankert und einen beispielhaften Gesetzgebungsproz
 ess begleitet. Das Gleiche haben wir bei E-Collecting vor\, mit dem wir di
 e direkte Demokratie der Schweiz auf ein neues Level heben wollen.\n\n\n**
 Elektronisches Gesundheitsdossier:** Was macht man\, um eine Verschlechter
 ung bei einem Produkt zu kaschieren? Richtig\, man nimmt ein Rebranding vo
 r. Und so heisst das E-PD nun E-GD.\n\n\n**Kabelaufklärung:** Im Dezember 
 überraschte uns das Bundesverwaltungsgericht mit einem wegweisenden Urteil
 : Es beurteilte die Kabelaufklärung als nicht vereinbar mit der Bundesverf
 assung und der Europäischen Menschenrechtskonvention. Lässt das ganze aber
  5 Jahr laufen.\n\n\n**What the VÜPF:** Wie die Schweiz zudem plant\, das 
 freie Internet weitgehend abzuschaffen. Wie der Stand der Verschärfung ist
 . Was wir und du dagegen tun können?\n\n\n**Plattformregulierung:** Ein Vo
 rschlag zur Plattformregulierung wurde vom Bund ausgearbeitet - und nach d
 er Verhängung von 39% Strafzoll still und heimlich in der Schublade versen
 kt. Doch der Bund fasste Mut - und wagt einen zaghaften Aufbruch.\n\n\n**K
 I-Regulierung & Leistungsschutzrecht:** Und wieso getraut sich der Bund\, 
 ein Leistungsschuzrecht einzuführen? Und mit der Motion «Gössi» KI-Sprachm
 odelle mit Schweizer Daten zu gefährden? (Spoiler: wegen der Verleger-Lobb
 y)\n\n\n**Community in der Schweiz:** Winterkongress\, Diversity und ander
 e Aktivitäten.\n\n\nNach dem Vortrag sind alle interessierten Personen ein
 geladen\, die [Diskussion in einer self-organized Session](https://events.
 ccc.de/congress/2025/hub/en/event/detail/treffen-der-netzpolitischen-commu
 nity-der-sch_uoca) fortzusetzen. Es werden Aktivist:innen von verschiedene

DESCRIPTION:EntrySign opened the door to custom microcode on AMD Zen CPUs e
 arlier this year. Using a weakness in the signature verification we can lo
 ad custom microcode updates and modify behavior of stock AMD Zen 1-5 CPUs.
  While AMD has released patches to address this weakness on some CPUs\, we
  can still use unpatched systems for our analysis.\n\nIn this talk we cove
 r what we found out about microcode\, what we saw in the microcode ROM\, t
 he tooling we build\, how we worked to find out more and how you can write
  & test your own microcode on your own AMD Zen systems. We have our tools 
 up on https://github.com/AngryUEFI for everyone to play around with and ho
 pefully help us understand microcode more than we currently do.\nModern CP
 Us often translate the complex\, user visible instruction set like x86_64 
 into a simpler\, less feature rich internal instruction set. For simple in
 structions this translation is done by a fast path decoding unit. However 
 some instructions\, like `wrmsr` or `rdrand` are too complex to decode tha
 t way. These instructions instead are translated using a microcode decoder
  that can act almost like an execution engine. The microcode decoder still
  emits internal instructions into the pipeline\, but allows for features l
 ike conditional branches and calls & returns. All of this logic happens du
 ring a single x86_64 instruction and is usually hidden from the outside wo
 rld. At least since AMD K8\, launched in 2003\, AMD CPUs allowed updating 
 this microcode to fix bugs made in the original implementation.\n\nBuildin
 g on our [previous](https://media.ccc.de/v/34c3-9058-everything_you_want_t
 o_know_about_x86_microcode_but_might_have_been_afraid_to_ask) [experience]
 (https://media.ccc.de/v/35c3-9614-inside_the_amd_microcode_rom) with AMD K
 8 & K10 microcode and [EntrySign](https://bughunters.google.com/blog/54248
 42357473280/zen-and-the-art-of-microcode-hacking) [published](https://medi
 a.ccc.de/v/why2025-156-entrysign-create-your-own-x86-microcode-for-fun-and
 -profit) earlier this year\, we took a closer look at AMD Zen 1-5 CPUs. We
  build on top of [Zentool](https://github.com/google/security-research/tre
 e/master/pocs/cpus/entrysign/zentool) to understand more instructions and 
 created a set of tools to easily create microcode patches as well as apply
  them on CPUs. We can modify the behavior of instructions and observe some
  usually not visible internal state by supplying our own microcode update.
 \n\nLike on K8\, we extracted the physical ROM on the CPU using an electro
 n microscope to read the hardcoded microcode on a Zen 1 CPU. Using the und
 erstanding of the microcode encoding we could then start disassembling the
  contents and understand how some instructions are implemented. While ther
 e are still a lot of things we don't understand\, we could follow control 
 flow and analyze algorithms like the XXTEA decryption of the microcode upd
 ate.\n\nTo start off this work\, we implemented a set of tools that allow 
 easy testing of microcode updates without the need for a fully featured OS
 . That way we can run timing tests with low noise and don't risk data corr
 uption if we corrupt a vital instruction. To continue our naming scheme fr
 om our work on K8 we dubbed this the AngryTools\, all of them available on
  [GitHub](https://github.com/AngryUEFI). The core components are a UEFI ap
 plication running from RAM\, AngryUEFI\, and a Python framework for test w
 riting on a client computer\, AngryCAT. AngryUEFI starts on the test syste
 m and waits for AngryCAT tests supplied via TCP. These tests usually consi
 st of a microcode update that gets loaded on the target CPU core and a buf
 fer with x64 instructions that get run afterwards. AngryUEFI then sends ba
 ck information about the test execution. AngryUEFI also recovers most faul
 ts caused by invalid microcode\, often even allowing reuse of a CPU core a
 fter a failed test run. We also added some syscall-like interfaces to supp
 ort more complex data collection like [IBS](https://reflexive.space/zen2-i
 bs/).\n\nTo make it easier to write custom microcode updates we also imple
 mented [ZenUtils](https://github.com/AngryUEFI/ZenUtils)\, a set of Python
  tools. So far we support single line assembly and disassembly based on ar
 chitecture specification for Zen 1 & 2 with limited support for other Zen 
 architectures. We also include a macro assembler that can create a full mi
 crocode update from an assembly-like input file. Later we will also extend
  ZenUtils with utilities to sign and en/decrypt microcode updates. Current
 ly we rely on Zentool for these tasks.\n\nWe also show some basic examples
  of how microcode programs work\, from a simple CString strlen implementat
 ion in a single x64 instruction to a [subleq](https://esolangs.org/wiki/Su
 bleq) VM implemented entirely in microcode. These show off the basics of m
 icrocode programming\, like memory loads & stores\, arithmetic and conditi
 onal branches. We are also currently looking at other examples and more co
 mplex programs.\n\nWe hope this talk shows you how to start throwing rando
 m bits at your own AMD Zen CPU to figure out what each bit does and help u
 s in further understanding the instruction set. We welcome improvements to
  the tooling and even entirely new tools to help analyze microcode updates
  and the ROM.\n\nIf you are already familiar with EntrySign\, we only cove
 r the very basics of it and focus more on what we learned after having a f
 oothold in the microcode.\n

DESCRIPTION:Hegemony Eroding is an ongoing art project exploring how genera
 tive AI reflects and distorts cultural representation. Its name speaks to 
 its core ambition: to bear witness to the slow erosion of Western cultural
  hegemony by exposing the cracks in which other cultures shine through.\n\
 nThis talk will discuss the blurry boundary between legitimate cultural re
 presentation and prejudice in AI-generated media and how generative AI can
  be used as a tool to explore humanity's digital foot print.\nIt is permea
 ted by a critique of purely profit-driven AI development and it's tendency
  to blunt artistic exploration and expression.\nGenerative AI models inges
 t huge datasets gathered all over the web. Unsurprisingly\, they reflect d
 ecades of Western cultural hegemony. Yet\, the hegemony is not absolute.\n
 \nNon-Western motifs\, that is\, recurring patterns and themes with deep c
 ultural resonance\, can be discovered and reproduced across different gene
 rative AI models.\n\nIn this talk I will explain the methods I developed t
 o draw out motifs\, the journey I took and what I learned along the way. I
  will present motifs and use them to outline a space stretching from repre
 sentation to prejudice on the one hand and western to non-western depictio
 n on the other.\n\nFinally\, I will make a case for AI as a tool for cultu
 ral exploration and discuss how monetary incentives jeopardise this endeav
 our\, adding to the long list of reasons to break up monopolies with trans
 parent\, publicly-funded AI-models.\n

 g as more than code and machines—it’s a way of exploring the world through
  curiosity\, play\, and care. By taking things\, systems\, and ideas apart
 \, we uncover new perspectives and possibilities for change. Our space is 
 built around awareness\, inclusion\, and open access to knowledge. We aim 
 to create an environment where everyone can learn\, share\, and experiment
  freely—without the constraints of “normality.” From art and music to acti
 vism and technology\, The Spectrum brings together diverse disciplines and
  beings to co-create\, collaborate\, and imagine better futures.\n\nAt 39C
 3\, we want to share our experiences of building such a space: how awarene

 Leibe.\nSome kids have a hard to hold back desire to open and dismantle ha
 rdware. While this is usually a hacker parents' nightmare\, who wants to f
 ind the home sever in pieces\, we got the cache to turn it into a learning
  experience where kids can tear old computers apart and get an explanation
  what the parts they just unscrewed are used for. Maybe we also put back e
 verything together afterwards and count lost screws.\n

DESCRIPTION:Aktuell sind mir 99 deutschsprachige Fahrradpodcasts bekannt - 
 vermutlich seit 2009. Eine eigene kleine Nische\, die ich euch vorstellen 
 möchte.\nIn Zusammenarbeit mit dem grandiosen Magazin fahrstil habe ich 20
 24 alle deutschsprachigen Fahrradpodcasts herausgesucht - es waren ca. 70.
  Mittlerweile sind es 99 und ich bin mir sicher\, immer noch nicht Alle ge
 listet zu haben: https://podcasts.regines-radsalon.de\n\nWas hat es mit di
 eser Podcaster*innen-Community auf sich und was lässt sich mit so einer Sa
 mmlung anstellen? Erstaunlich ist\, daß fast alle gefundenen Podcasts noch
  vollständig im Netz auffindbar sind.\n\nEs bleibt vermutlich work in prog
 ress in vielerlei Hinsicht. Manches geht und ist sogar unterhaltsam wie et
 wa die FahrradPodcastAdventsrallye\, die im Dezember 2025 zum dritten Mal 
 im Fediverse stattfinden wird. Anderes wird vermutlich nie richtig funktio
 nieren wie etwa konsistente Daten aller deutschsprachigen Fahrradpodcasts 
 zu etwa dem Genderverhältnis der Gästys zu bekommen.\n

 uch in der Chaosfamilie? Welche Themen des 39C3 könnten für die DH relevan
 t sein - und umgekehrt?\nDigital Humanities: Forschung zu Literatur\, Gesc
 hichte\, Sprache\, Kunst\, Musik in digitaler Form - von Rechercheprozesse
 n über Analysemethoden bis hin zu Publikationsformen. Als Brückendisziplin
  zwischen IT und geisteswissenschaftlichen Fächern operieren die "DH" aber
  nicht nur anwendungsbezogen\, sondern auch transformativ: Sie evaluieren 
 kritisch im Diskurs\, welche Aspekte der fortlaufenden Digitalisierung für
  die wissenschaftliche Praxis förderlich genutzt werden können.\n\nDamit s
 orgen sie aber auch stets für Aufregung\, wenn es darum geht\, etablierte 
 wissenschaftliche Prozesse zu stören: Etwa\, wenn es um Open Source\, Open
  Science\, Open Data geht sowie um FAIR- und CARE-Prinzipien oder um nicht
 proprietäre Standards. Wir begleiten als Digital Humanists somit nicht nur
  die Digitalisierung von Kulturdokumenten und Wissenschaft(sbürokratie)\, 
 sondern auch von Arbeitsprozessen mit dem Ziel\, in diesem Zuge auch eine 
 freiere\, fairere\, nachhaltigere\, zugänglichere\, offenere und digitalso
 uveränere Wissenschaftspraxis zu etablieren.\n\nWir schließen an die Meetu
 ps der letzten beiden Jahre an und treffen uns wieder zu einem lockeren Ke

 e Themen des 39C3 könnten für die DH relevant sein und umgekehrt? Kommt za

DESCRIPTION:Workshop with Debra Guckenheimer\nInspired by Canadian disabled
  artist Margeaux Feldman\, this project is a practice of resisting ableism
  and other dehumanizing systemic oppressions. Debra Guckenheimer has taken
  discarded books and created collages to feature as a backdrop to an affir
 mation. The affirmation is a rejection of an ableist message she received 
 with a disability justice message on the back. She has distributed over 10
 0 postcards around the world to friends and strangers\, who keep the postc
 ard up to recite the affirmation as needed. Audience and artist together c
 reate change as they practice letting go of harm. This is Debra's first ex
 hibit in Germany\, the home of her grandparents until they fled in 1933\, 
 as Debra practices healing some of the trauma her ancestors experienced. T
 his workshop is dedicated to the late disability justice Alice Wong and th
 e ancestors of Debra who were murdered by Nazis. Attendees will receive a 
 disability justice postcard (limited quantity available) to practice heali
 ng and resistance.\n

DESCRIPTION:Workshop with Christian Faubel\n\n* DAY 2: 16:30 - 19:30\n* DAY
  3: 16:00 - 19:00\nPerformance DAY 4: art&play [tba]\nThis is an advanced 
 soldering workshop for creating motorcontrollers that bring motors to tap 
 rhythmically with each other. Each participant builds her own board to dri
 ve two motors that will then tap in polyrhythms. The electronic circuits i
 n this workshop derive from minimal and low-cost bio-inspired robots. Osci
 llators are used to drive motors that produce sound\, but they can also be
  connected to synthesizers. Each circuit board is designed to be wired up 
 with the boards from the other participants in order to explore together t
 he magic of emergent polyrhythm by wiring their individual circuits to for
 m a huge network.\nBig fun and deep dive into analog circuits and their em
 ergent properties.\n\n\nLink: [https://christian.faubel.derstrudel.org](ht

DESCRIPTION:Wie die letzten Jahre gute Tradition geworden ist\, blicken Mel
 anie Bartos und Bernd Rupp zurück auf das wissenschaftspodcasts.de-Jahr 20
 25 und sprechen über die Perspektiven\, die sich für das Wissenschaftspodc
 ast-Jahr 2026 abzeichnen.\nDabei beleuchten wir die Herausforderungen bei 
 der Kuration\, die Anmeldezahlen neuer Wissenschaftspodcasts\, die Weitere
 ntwicklung der Website sowie den Aufbau und die Betreuung der WissPod-Comm
 unity. Diese umfasst inzwischen rund 420 Wissenschaftspodcasts mit insgesa
 mt über 33.000 Episoden.  2025 wurde erstmalig ein Podcast-Adventskalender
  mit 24 kuratierten Spezial-Podcast-Episoden aufgesetzt.\n\nWie die letzte
 n Jahre reden wir aber auch über ein Thema\, das die Wissenschaft aber auc
 h die Wissensvermittlung oder Wissenschaftskommunikation beeinflusst.  Die
 ses Jahr geht es dabei um KI in der Wissenschaft.  Wir blicken auf Chancen
  und Risiken: In der individuellen Perspektive der einzelnen Wissenschaftl
 er*innen ergeben sich oft große Möglichkeiten zur Beschleunigung der eigen
 en Arbeit.  Dabei geht man aber leicht eine Beziehung mit großen Tech-Konz
 ernen mit unklaren Interessen und Zielen ein. Daraus ergibt sich der Bedar
 f einer Wahrheitsschutz-Gesamtrechnung für eine Wissenschaft in der KI flä
 chendeckend eingesetzt wird.\nMit unseren Gästen sprechen wir über Podcast
 s in der Wissen{schaft}skommunikation\, über Ziele und Kriterien – und dar
 über wie KI die Wissenschaft verändert.\n

DESCRIPTION:Der Hype um künstliche Intelligenz ist allgegenwärtig. Selbst D
 onald Trump postet KI-generierte Videos\, in denen er sich wahlweise als R
 ockstar oder Kampfjetpilot inszeniert. Elon Musk prahlte öffentlich damit\
 , dass in seinem "Department of Goverment Efficiency" der soziale Kahlschl
 ag mit Unterstützung Künstlicher Intelligenz vorangetrieben wird. Und Pete
 r Thiel meint allen ernstes\, KI-Regulierung und das Erscheinen des Antich
 risten gingen Hand in Hand. Müssen wir uns Sorgen machen?\nRainer Mühlhoff
  ist Professor für Ethik und kritische Theorien der Künstlichen Intelligen
 z an der Universität Osnabrück. In seinem kürzlich erschienen Buch "Künstl
 iche Intelligenz und der neue Faschismus" setzt er sich kritisch mit dem K
 I-Hype auseinander. Und er erklärt\, welche toxischen Ideologien zentraler
  Akteure aus dem Silicon Valley Menschen empfänglich für autoritäre Gesell
 schaftsbilder machen.\n\nWir sprechen über die Zyklen von KI-Hypes\, das p
 roblematische Narrativ vom "Bürokratieabbau durch AI" und die Funktion apo
 kalyptischer Zukunftsvisionen. Vor allem aber will ich von Rainer wissen: 
 Welche Bedeutung haben bei dieser Debatte die in Teilen des Silicon Valley
  einflussreichen ideologischen Strömungen – von radikalem Cyberlibertarism
 us über Longtermismus bis hin zum "Dark Enlightment"?\n

DESCRIPTION:3D-Printers have given us all the unprecedented ability to manu
 facture mechanical parts with a very low barrier to entry.  The only thing
  between your idea and its physical manifestation is the process of design
 ing the parts. However\, this is actually a topic of incredible depth: Des
 ign engineering is a whole discipline to itself\, built on top of tons and
  tons of heuristics to produce shapes that are functional\, strong\, and i
 mportantly: well-manufacturable\n\nIn this talk\, I will present the rules
  for designing well-printable parts and touch on other areas of design con
 siderations so you can learn to create parts that work first try and can b
 e reproduced by others on their 3d-printers easily.\nOver the years\, the 
 3d-printing community has discovered many tricks and rules that help creat
 ing parts that can be printed well and fulfill their purpose as best as po
 ssible. I started collecting these rules and wrote an article guide to mak
 e this knowledge more accessible. I want to present the most important pri
 nciples and the mindset that is needed to achieve perfected design.\n\nThi
 s is not about how to use a CAD program to design a part — but rather abou
 t the thought process of the design engineer while drawing up a part.  A t
 hough process that consists of compromises between many objectives\, of he
 uristic rules\, and many neat little tricks.\n\nThe article that this talk
  is based on can be found on my blog: https://blog.rahix.de/design-for-3d-

DESCRIPTION:when datasets are scaled up to the volume of (partial) internet
 \, together with the idea that scale will average out the noise\,  large d
 ataset builders came up with a human-not-in-the-loop\, cheaper-than-cheap-
 labor method to clean the datasets: heuristic filtering. Heuristics in thi
 s context are basically a set of rules came up by the engineers with their
  imagination and estimation to work best for their perspective of “cleanin
 g”. Most datasets use heuristics adopted from existing ones\, then add som
 e extra filtering rules for specific characteristics of the datasets. I wo
 uld like to invite you to have a taste together of these silent\, anonymou
 s yet upheld estimations and not-guaranteed rationalities in current socio
 technical artifacts\, and on for whom these estimations are good-enough\, 
 as it will soon be part our technological infrastructures.\nIn 1980s\, non
 -white women’s body size data was categorized as dirty data when establish
 ing the first women's sizing system in US. Now in the age of GPT\, what is
  considered as dirty data and how are they removed from massive training m
 aterials?\n\nDatasets nowadays for training large models have been expande
 d to  the volume of (partial) internet\, with the idea of “scale averages 
 out noise”\, these datasets were scaled up by scrabbling whatever availabl
 e data on the internet for free then “cleaned” with a human-not-in-the-loo
 p\, cheaper-than-cheap-labor method: heuristic filtering. Heuristics in th
 is context are basically a set of rules came up by the engineers with thei
 r imagination and estimation that are “good enough” to remove “dirty data”
  of their perspective\, not guaranteed to be optimal\, perfect\, or ration
 al.\n\nThe talk will show some intriguing patterns of “dirty data” from 23
  extraction-based datasets\, like how NSFW gradually equals to NSFTM (not 
 safe for training model)\, and reflect on these silent\, anonymous yet uph
 eld estimations and not-guaranteed rationalities in current sociotechnical
  artifacts\, and ask for whom these estimations are good-enough\, as it wi

DESCRIPTION:Humanity has already crossed the point where simply reducing em
 issions will no longer be enough to keep global warming below 2°C. Accordi
 ng to the IPCC (AR6\, WGIII)\, it is now essential to actively remove gree
 nhouse gases from the atmosphere in order to meet global climate targets\,
  maintain net-zero (or even net-negative emissions)\, and address the burd
 en of historical emissions. At the same time\, degraded soils and the clim
 ate crisis are a threat to global food security.\nTwo years ago\, I presen
 ted an overview of different methods available for carbon dioxide removal.
  Today\, I want to show you an example of how CO₂ can be removed from the 
 atmosphere while simultaneously improving the lives of local communities:\
 n\nHuman shit.\n\nHuman shit is a high abundant biomass\, contains critica
 l nutrients for global food security\, and causes serious health and envir
 onmental issues from poor or non-existent treatment outside industrial cou
 ntries. Converting shit into biochar presents a powerful solution: the pro
 cess eliminates contaminants\, stabilizes and locks away carbon\, and can 
 be used to improve agricultural soils. The challenge is that most nutrient
 s in this biochar are not accessible to plants. To overcome this\, I mixed
  human and chicken shit and produced a “Superchar” that releases far more 
 nutrients. It’s not magic\, it’s just some chemistry and putting aside you
 r prejudices and disgust. I’ll show you how I did some shit experiments in
  Hamburg and Guatemala and how you can do it too.\nToday’s science mostly 
 follows worn-out pathways and lack big discoveries and innovations. Scient
 ists often don’t want to take a risk because the competition for a permane
 nt position in academia is so high\, which pressures them into conservativ
 e research topics supported by their supervisors. Even when science provid
 es helpful solutions for urgent problems\, the knowledge mostly ends up in
  libraries\, written in papers that nobody understands. I want to show tha
 t it is worthwhile to follow research ideas that are unconventional\, upse
 t your boss af and explore topics that are unpopular like working with shi
 t. I hope that sharing stories of how a funny idea turned into a solution 
 encourage others to start making impact in their environment.\n

  der Militärtechnik“ und die Beziehung zwischen Mensch und Maschine ist se
 it Jahrzehnten ein Thema in der Friedensbewegung\, der Konfliktforschung\,
  der Philosophie\, den Sozialwissenschaften und den kritischen Data & Algo
 rithm Studies. Doch in den letzten Jahren wurden Waffensysteme mit KI-Komp
 onenten entwickelt und auch praktisch in bewaffneten Konflikten eingesetzt
 . Dabei reicht die Anwendung von Drohnensteuerung über optische Zielerfass
 ung bis hin zur logistischen Zielauswahl. Am Beispiel KI-gestützter Zielwa
 hlsysteme\, die vom israelischen Militär seit Mai 2021 und insbesondere je
 tzt im Genozid in Gaza eingesetzt werden\, können die aktuellen technische

 Personen\, das System Where's Daddy? zur Zeitplanung von Angriffen und ein
  experimentelles System auf Basis großer Sprachmodelle zur Erkennung milit
 ärisch relevanter Nachrichten in palästinensischen Kommunikationsdaten.\n\
 nAuf Basis der Aussagen von Whistleblower:innen des israelischen Militärs 
 und Angestellten beteiligter Unternehmen wie Amazon\, Google oder Microsof

DESCRIPTION:The French ISP 'Free' was the first to introduce a set-top box 
 in France in 2002\, named the Freebox. Four years later\, the fifth versio
 n of the Freebox was released and distributed to customers. It comprises t
 wo devices: a router\, and a PVR called the Freebox HD\, both running Linu
 x. The Freebox HD had innovative features at the time\, such as live telev
 ision control and HD capabilities.\n\nSuch a device has a lot of potential
  for running homebrew\, so I decided to hack it. I present how I got arbit
 rary code execution on the Freebox HD and then root privileges\, using a c
 hain of two 0-day exploits\, one of which is in the Linux kernel. I then a
 nalyze the device\, run homebrew software\, and explain the structure of t
 he ISP's private network that I uncovered while exploring the device.\nThe
  Freebox HD is a set-top box with media player capabilities designed and b
 uilt by the French ISP 'Free' in 2006\, and distributed to customers since
  (including me). It is still in use and will be maintained until the end o
 f 2025.\n\nWhen I got it\, I wanted to run homebrew software on it\, so I 
 decided to reverse engineer it. The initial goal was to get arbitrary code
  execution. The Freebox HD being largely undocumented\, this talk shows th
 e full process of reverse engineering it from scratch:\n* Initial visual i
 nspection\n* Disassembly and inspection of the insides\n* Attack surface a
 nalysis and choice of the target\n* Search and exploitation of a vulnerabi
 lity in PrBoom (a Doom source port running on the Freebox HD)\n* Analysis 
 of the Linux system running on the Freebox HD\n* Search and exploitation o
 f a Linux kernel exploit to escape the sandbox and gain root privileges\n*
  Decryption and dump of the firmware\n* Analysis of the Linux system and t
 he programs of the Freebox HD\n* Playing with the remote control capabilit
 ies\n* Reverse engineering of the private networks of the ISP\n\nThe two e
 xploits used to gain full root access were both discovered for this specif
 ic hack\, which makes them 0-day exploits.\n\nThe analysis leads to some i
 nteresting discoveries about the device itself\, but also the ISP\, how th
 eir technical support works and accesses the devices remotely\, and much m
 ore!\n

DESCRIPTION:Mobile phones are central to everyday life: we communicate\, en
 tertain ourselves\, and keep vast swaths of our digital lives on them. Tha
 t ubiquity makes high-risk groups such as journalists\, activists\, and di
 ssidents prime targets for sophisticated spyware that exploits device vuln
 erabilities.\n\nOn Android devices\, GPU drivers have repeatedly served as
  the final escalation vector into the kernel. To study and mitigate that r
 isk\, we undertook a research project to virtualize the Qualcomm Android k
 ernel and the KGSL graphics driver from scratch in QEMU. This new environm
 ent enables deep debugging\, efficient coverage collection\, and large-sca
 le fuzzing across server farms\, instead of relying on a handful of prepro
 duction devices.\n\nThis talk will highlight the technical aspects of our 
 research\, starting with the steps required to boot the Qualcomm mobile ke
 rnel in QEMU\, all the way up to the partial emulation of the GPU. Then\, 
 we will present how we moved from our emulation prototype to a full-fledge
 d fuzzer based on LibAFL QEMU.\nMobile phone manufacturers ship competitiv
 e hardware supported by increasingly complex software stacks\, ranging fro
 m firmware and bootloaders to kernel modules\, hypervisors\, and other Tru
 stZone environments. In an effort to keep their products secure\, these co
 mpanies rely on state-of-the-art testing techniques such as fuzzing. They 
 commonly perform their fuzzing campaigns on-device to find vulnerabilities
 . Unfortunately\, this approach is expensive to scale and does not always 
 provide fine-grained control over the target. To address these issues\, we
  approached the problem through the prism of emulation\, by partially reim
 plementing the hardware as a normal software to run on a computer. That wa
 y\, we could scale fuzzing instances\, and gain full control over the emul
 ated target.\n\nThe presentation will outline how we made the full emulati
 on of Qualcomm’s Android ecosystem possible by tweaking the complex build 
 system of the Android image and implementing a custom board (including mor
 e than 10 custom devices) in QEMU. We will review the steps required and t
 he technical challenges encountered along the way.\n\nAfter providing a qu
 ick recap and the latest updates on LibAFL QEMU (presented at 37C3) by one
  of the LibAFL maintainers\, we will delve into the gory details of how we
  partially emulated the latest version of Adreno—the GPU designed by Qualc
 omm—and built a fuzzer for its Android kernel driver. In particular\, we w
 ill show how LibAFL QEMU was integrated into our custom board and the few 
 improvements we made to the kernel to get better coverage with KCOV. Final
 ly\, we will demonstrate how our approach enabled us to find a new critica
 l vulnerability in the GPU kernel driver.\n

 n wüste Bündnisse aus CDU\, Die Linke\, SPD und BSW entstehen. Kurzum: LSA

 rauchen unseren Support und wir zeigen euch Möglichkeiten wie dieser ausse

 rte das Portal mit „realistischen“ KI-Chatbots. Die Bots waren so überzeug
 end\, dass sie die Überprüfungen umgingen und sogar als „weiß“ verifiziert
  worden. Durch die Gespräche und Recherche von digitalen Spuren dieser Gem
 einschaft\, die sich in Sicherheit wähnte\, konnte sie Nutzer identifizier
 en.\n\nGemeinsam mit Reporter:innen der „Die Zeit“ konnten wir die Person 
 hinter der Plattform enttarnen und ihre Radikalisierung von einer erfolgre
 ichen Pianistin zu einer Szene-Unternehmerin nachzeichnen. Um ihr Dating-P
 ortal hat sie ein Netzwerk von Websites aufgebaut\, dass seinen Nutzern Li
 ebe\, Treue und Tradition vermarktet. WhiteDate verspricht romantische Bez
 iehungen\, WhiteChild propagiert Familien- und Abstammungsideale und White
 Deal ermöglicht berufliches Networking und „gegenseitige Unterstützung“ un
 ter einem rassistischen Weltbild. Gemeinsam zeigen sie\, wie Ideologie und
  Einsamkeit auf bizarre Weise miteinander verwoben sein können.\n\nNach mo
 natelanger Beobachtung\, klassischer OSINT-Recherche\, automatisierter Ges
 prächsanalyse und Web-Scraping haben wir herausgefunden\, wer hinter diese
 n Plattformen steckt und wie ihre Infrastruktur funktioniert. Dabei deckte
 n wir die Widersprüche und Absurditäten extremistischer Gemeinschaften auf
 \, verdeutlichten ihre Anfälligkeit für technologische Eingriffe und brach
 ten sogar den einen oder anderen Nazi zum Weinen.\n\nDieser Vortrag erzähl
 t von Beobachtung\, Schabernack und Einblicken in die digitale Welt extrem
 istischer Gruppen. Er zeigt\, wie Algorithmen\, KI-Personas und investigat
 ives Denken Hass entlarven\, seine Narrative hinterfragen und seine Echoka
 mmern aufbrechen können. Wir zeigen\, wie Technologie im Kampf gegen Extre
 mismus eingesetzt werden kann.\n

DESCRIPTION:Oder: Wie die Hamburger Polizei queere Menschen auf öffentliche
 n Toiletten observierte\, und wie ein anonymes Kollektiv im Juli 1980 dies
 es Überwachungsystem wortwörtlich mit dem Hammer zerschlagen hat. Ein anal
 oger Überwachungskrimi mit sauberen Städten\, lichtscheuen Elementen\, que
 erem Aktivismus\, und kollektiver Selbstorganisation\; und mit einer Anlei
 tung wie man Beamten Anfang der 80er das Handwerk legen konnte.\nIn den 19
 70er Jahren nutzt die Hamburger Polizei auf zehn öffentlichen Herrentoilet
 ten in der Wand eingelassene Spionspiegel\, um zu beobachten welche Männer
  am Pissoir ihrer Meinung nach etwas zu lange nebeneinander stehen. In ein
 em Überwachungszeitraum von gut 18 Jahren sprechen Hamburger Beamte mit Be
 rufung auf ‚Jugendschutz‘ und ‚Sauberkeit‘ hunderte Hausverbote an öffentl
 ichen Toiletten aus\, nehmen Personalien auf und legen dabei illegalerweis
 e ‚Rosa Listen‘ genannte Homosexuellenregister an. \nDie unfreiwillige Pee
 p-Show endet im Sommer 1980\, als die Polizei völlig indiskret die Teilneh
 menden der ersten lesbisch-trans-schwulen Demonstration in Hamburg fotogra
 fiert um nach Selbstaussage „die Karteien aufzufrischen“. Ein anonymes Kol
 lektiv zerschlägt die Überwachungsspiegel und bringt die illegale Polizeip
 raxis ans Licht der Öffentlichkeit.\nMit zwei Fragen tauchen wir in diesem
  Vortrag in die Aborte der Geschichte: Wie ist das polizeiliche Toilettenü
 berwachungssystem in Hamburg entstanden? Welche technischen und sozialen L
 ücken nutzten die Aktivist:innen für den Exploit dieses Systems? Und was h
 at das eigentlich mit heute zu tun?\n

DESCRIPTION:Eine zwar profane Methode der Überwachung\, die Polizeibehörden
  in Deutschland jedoch hunderttausendfach anwenden\, ist das Auslesen von 
 Daten beschlagnahmter Smartphones und Computer. Dazu nutzt die Polizei Sic
 herheitslücken der Geräte mithilfe forensischer Software von Herstellern w
 ie Cellebrite oder Magnet aus. Die Verfassungsmäßigkeit der Rechtsgrundlag
 en ist zweifelhaft. Im Vortrag werden anhand aktueller Fälle technische un
 d juristische Hintergründe erörtert.\nStaatstrojaner\, Chat-Kontrolle\, Wa
 nzen. Die Mittel staatlicher Überwachung sind vielfältig und teilweise tec
 hnisch sehr komplex. Dabei ist es leicht\, den Überblick zu verlieren. Ein
  relativ profanes Mittel\, das Polizeibehörden in Deutschland hunderttause
 ndfach anwenden\, ist die Beschlagnahme von Smartphones und Laptops sowie 
 das Auslesen ihrer Daten. Genaue Statistiken gibt es nicht. Es dürften jed
 och mehr Fälle sein als bei der einfachen Telekommunikationsüberwachung. A
 llein in Sachsen-Anhalt waren es innerhalb von fünf Jahren 13.000 Smartpho
 nes.\n\nAuch bei leichten Straftaten und Ordnungswidrigkeiten beschlagnahm
 t die Polizei regelmäßig Datenträger - insbesondere Smartphones und Laptop
 s - etwa beim Verdacht einer Beleidigung oder bei der Handynutzung im Stra
 ßenverkehr. Oft werden auch Hausdurchsuchungen durchgeführt und dabei alle
  technischen Geräte beschlagnahmt und durchsucht. Die Verfassungsmäßigkeit
  dieser polizeilichen Praxis ist sehr zweifelhaft. Das Bundesinnenminister
 ium plante in der letzten Legislatur sogar\, die Kompetenzen der Polizei a
 uszuweiten wodurch auch heimliche Hausdurchsuchungen möglich werden sollte
 n. Damit könnte die Polizei heimlich Staatrojaner installieren oder sog. E
 vil-Maid-Angriffe vorbereiten. Die Strafverfolgungsbehörden stützen sich a
 uf die Beschlagnahmevorschriften der §§ 94 ff. Strafprozessordnung\, die s
 eit 1877 im Wesentlichen unverändert geblieben sind und in ihrem Wortlaut 
 weder die Möglichkeit eines Datenzugriffs noch die Modalitäten und Grenzen
  einer Datenauswertung regeln. Auch wird die Maßnahme nicht auf Straftaten
  einer gewissen Schwere begrenzt und es fehlen Vorgaben zum Schutz besonde
 rs sensibler Daten\, die etwa in den Kernbereich der persönlichen Lebensfü
 hrung fallen. Im Rahmen einer Durchsuchung ermöglicht es der §§ 110 Strafp
 rozessordnung eine vorläufige Sicherung und Durchsicht der Speichermedien.
  Auch diese Vorschrift reicht nicht aus\, um Grundrechte angemessen zu sch
 ützen\, da mit der kompletten Ausforschung des gesamten Datenbestandes ein
  gravierender Grundrechtseingriff in die Privatsphäre der Betroffenen verb
 unden ist und gesetzlich keine angemessenen Grenzen gesetzt werden.\n\nGer
 ade auf Smartphones befinden sich oft höchstpersönliche Daten wie Chats mi
 t der Familie oder dem*der Partner*in\, Fotos\, Kontakte\, Standortdaten u
 nd Dating-Apps. Darüber hinaus sind die Geräte regelmäßig mit Cloud-Dienst
 en und anderen Datenträgern verbunden. Auf all diese Daten können Polizeib
 ehörden dann zugreifen.\nMöglich wird das durch Software von Firmen wie Ce
 llebrite\, MSAB oder Magnet. Diese nutzen Sicherheitslücken aus\, um die V
 erschlüsselung von Smartphones zu knacken. Wie auch bei Sicherheitslücken 
 für Staatstrojaner sind die Sicherheitslücken\, die diese Firmen ausnutzen
 \, den Herstellern nicht bekannt. Damit unterstützen deutsche Behörden ein
  System\, dass die Geräte aller unsicher macht. Auch die Bitlocker-Verschl
 üsselung von Windows-Computern lässt sich oft umgehen. Dies ermöglicht den
  Strafverfolgungsbehörden den freien und unbeschränkten Zugang zu allen pe
 rsönlichen Daten\, ohne angemessene gesetzliche oder gerichtliche Kontroll
 e und Überprüfung. Auch für die betroffenen Personen wird nicht erkennbar\
 , in welchem Ausmaß Daten durchsucht und ausgewertet wurden. Im Vortrag wi
 rd der aktuelle Stand und die Probleme von Verschlüsselung von Windows und
  Linux Computern sowie Android und iOS Smartphones erläutert.\n\nAm Beispi
 el des Journalisten Hendrik Torners\, dessen Smartphone beschlagnahmt wurd
 e\, nachdem er eine polizeiliche Maßnahme nach einer Klimademonstration be
 obachtet hatte und nun im Rahmen einer Verfassungsbeschwerde dagegen vorge
 ht\, sowie weiterer öffentlich diskutierter Fälle wie [#Pimmelgate](https:
 //events.ccc.de/congress/2025/hub/tag/Pimmelgate) besprechen die Vortragen
 den die technischen und juristischen Hintergründe.\n

DESCRIPTION:\nIn Leipzig\, the initiative Nein zur Bezahlkarte (“No to the 
 Payment Card”) has been organizing a solidarity-based voucher exchange for
  over a year to circumvent the harassment and discrimination of asylum see
 kers caused by the payment card system. The voucher exchange has now reach
 ed a scale that presents us with organizational challenges:\n1.  To organi
 ze the exchange as coordinately as possible—and thus as fairly and stress-
 free as possible for everyone interested in exchanging—we work with a regi
 stration system. This requires a great deal of communication\, which curre
 ntly takes place via WhatsApp. As demand and thus the number of requests c
 ontinue to grow\, the communication effort can hardly be managed in this w
 ay any longer.\n2.  We constantly need more money to meet the growing dema
 nd. This leads to an ever-increasing cash reserve that must be managed by 
 the initiative. We therefore want to decentralize our offering—and with it
  the cash reserve—and empower more small groups and initiatives to create 
 decentralized exchange offers that are nevertheless coordinated with each 
 other.\n    To this end\, we have developed an app idea intended to serve 
 as a platform where exchange offers created in a decentralized manner can 
 be posted\, and which people with payment cards who want to exchange vouch
 ers for cash can access in a low-hierarchy way to search for an exchange o
 ffer. The app is intended to be available nationwide for the dozens of exc
 hange initiatives. In this way\, it aims to help ensure that the voucher e
 xchange—emerging in many places from spontaneous solidarity-based practice
 —can remain possible in the long term\, as long as the discriminatory prac
 tice of payment cards is not abolished by federal legislation.\n    We hav
 e developed a basic structure for the app\, which is to be implemented by 
 two developers next year. At the SoS\, we would like to invite people to a
  hackspace in order to present the development of the app and reach out to
  more people with coding skills\, and to motivate them to support the work
 .\n

  oppressive security and surveillance systems while actively engaging with
  activism and political while actively engaging with activism and politica
 l\nmovements. Because of this\, I've been put on movements. Because of thi
 s\, I've been put on a watch-list by the French government’s government’s 
 intelligence services.\n\nI believe that we need to better understand\, to
  understand the control and crushing power forced upon us\, the people\, b

 of this global business. Together\, we'll investigate the making of busine
 ss. Together\, we'll investigate the making of wars\, the globalization of
  surveillance and the wars\, the globalization of surveillance and the\nbu
 siness of repression.\n\nThe aim of this investigation is to shed light on
  the inner workings of a system by letting its main inner workings of a sy
 stem by letting its main players tell their own stories\, face-to-face wit

DESCRIPTION:\nInstagram\, Facebook\, TikTok und co sind aus linker und/oder
  herrschaftskritischer Perspektive hoch problematisch. In a Nutshell lasse
 n sich diese Dienste im Grunde zusammenfassen als digitale Designerdrogen 
 mit einem Algorithmus der auf maximale Suchterzeugung optimiert ist. Im Gr
 unde eines der ethisch fragwürdigsten Produkte die der Kapitalismus des 21
 . Jahrhunderts zu bieten hat. Dazu zentralisiert in den Händen von den eke
 lhaftesten der ekelhaften Großkonzerne und mit völlig normalisierter sexis
 tischer und queerfeindlicher Zensur. Hier ließen sich noch eine Million we
 itere Gründe anführen\, warum diese Dienst nicht nur aus linker und herrsc
 haftskritischer Perspektive nicht genutzt werden sollten\, sondern eigentl
 ich neben Kohlekraftwerken und Waffenfabriken eines der Hauptziele von uns
 eren Aktionen sein sollten. Aber nein\, in den allermeisten linken und ana
 rchistischen Kontexten\, wird Instagram und co völlig unkritisch genutzt. 
 Teilweise wird es sogar von Linken aktiv beworben oder es wird vorausgeset
 zt es zu nutzen um Informationen zu bekommen. What the Fuck?\n\nWir wollen
  darüber reden\, wie um alles in der Welt es soweit kommen konnte und was 
 wir dagegen tun können.\n\nPlease: Das ist kein Ort für die Grundsatzdebat
 te ob Instagram und co denn "wirklich so schlimm" sind. Wenn ihr so eine S
 ession wollt macht eure eigene. Das hier soll eine Veranstaltung für Mensc
 hen sein\, die die Kritik teilen und sich darüber austauschen wollen\, wie
  sie in linker Szene Bewusstsein für die Problematik schaffen können. Und:
  es soll explizit um linkspolitische Kontexte gehen.\n

DESCRIPTION:\n"Generative KI" und "Large Language Models" sind eine Technol
 ogie\, bei der sich zunehmend abzeichnet\, dass es nicht nur ein schräger 
 Hype ist\, sondern eine disruptive Technologie\, die das Potential hat uns
 ere Gesellschaft entscheidend zu verändern. Aus linksradikaler Perspektive
  müsste die Folgefrage sein: "verändert diese Technologie die Gesellschaft
  zum besseren\, zum schlechteren oder ist das offen?" und darauf folgend "
 Falls zweiteres\, was können wir dagegen tun und falls letzteres\, wie kön
 nen wir dagegen Einfluss nehmen?" Aber aktuell stellen sich linkspolitisch
 e Kontexte diese Fragen gar nicht. Mit der völligen Akzeptanz von Instagra
 m und co (https://events.ccc.de/congress/2025/hub/de/event/detail/gesprach
 srunde-zum-umgang-linksradikaler-und-anarc) scheinen linke Bewegungen jedo
 ch völlig verlernt zu haben\, kritisch über Technologien nachzudenken und 
 zu diskutieren. In großen Teilen linker und anarchistischer Szene\, findet
  zu dem Thema gerade keine Debatte statt\, von Aktionen ganz zu schweigen.
  Vielleicht liegt es an einem Gefühl der Machtlosigkeit\, dass man doch so
 wieso keinen Einfluss auf Entwicklung und Nutzung von Technologien hat? Ab
 er das ist erwiesenermaßen falsch\, man muss nur einen Blick auf die Kämpf
 e gegen Gentechnik\, Atomkraft und Kohlekraft werfen. In allen Fällen konn
 te durch direkte Aktion nennenswert Einfluss genommen werden und zumindest
  die Dominanz dieser Technologien deutlich eingedämmt werden.\n\nMeine The
 se\, die ich als Grundannahme für diesen Workshop voraussetze: Es handelt 
 sich hier um eine Technologie\, die die Welt (und insbesondere das Interne
 t) schlechter und nicht besser macht und es ist sinnvoll sie mit allen Mit
 teln die möglich sind zu bekämpfen. Vielleicht ist sie neben dem Klimawand
 el die größte Gefahr unserer Zeit. Deshalb wollen wir hier darüber diskuti
 eren\, was für Möglichkeiten für den Kampf gegen "KI" wir haben\, welche A
 ktionsformen aus Anti-Gentechnik/Atomkraft/Kohle-Bewegung sich adaptieren 
 lassen und welche nicht und wie wir endlich Bewusstsein in unsere politisc
 hen Kontexten dafür schaffen können\, dass das fucking wichtig ist.\n\nUnd
  bitte: die Grundannahme will ich in genau diesem Workshop nicht diskutier
 en. Gerne sonst immer\, auch gerne in einer eigenen Session. Aber hier sol
 l es um einen Austausch für Menschen gehen\, die diese Grundannahme teilen
 . Und bitte: Keine Militanzdebatten. Sonst reden wir über nichts anderes. 
 Auch Diversity of Tactics würde ich für die Debatte gerne als gegeben vora
 ussetzen.\n

DESCRIPTION:Improvisierte elektronische Musik auf einem hybriden Setup\, be
 stehend aus einem kleinen modularen System und digitalen Komponenten\, die
  in Pure Data programmiert sind. Der Fokus liegt auf der musikalischen Erf
 orschung roher elektronischer Klänge ohne den Einsatz von Echo\, Hall oder
  Loopern. Auch wenn es rhythmische Momente geben mag\, stehen diese nicht 
 im Mittelpunkt\, ebenso wenig wie Harmonie und Melodie – vielmehr sind tec
 hnische/mathematische Strukturen die Ausgangspunkte. Die ästhetische Anzie
 hungskraft entsteht durch die Akzeptanz des Klangmoments als kognitive Erf
 ahrung und die gemeinsame Wahrnehmung eines Spannungsbogens durch Publikum
  und Performer*in.\nImprovised electronic music on a hybrid setup consisti
 ng of a small modular system and digital components programmed in Pure Dat
 a. The focus is on the musical exploration of raw electronic sounds withou
 t the use of echoes\, reverb\, or loopers. Even though there may be rhythm
 ic moments\, these are not the focus\, nor are harmony and melody—rather\,
  technical/mathematical structures are the starting points. The aesthetic 
 appeal arises from the acceptance of the sound moment as a cognitive exper
 ience and the shared perception of a tension arc by the audience and perfo
 rmer.\n\n#### Artist Bio:\n\ni am an electronic/experimental musician\, co
 mposer\, improviser\, programmer based in leipzig/germany.\n\nafter more t
 han 3 decades as a professional musician and instrumental teacher in vario
 us styles and on various traditional instruments\, i have become a little 
 bored and saturated with it. in addition\, i have felt the desire to devot
 e my life to other tasks such as left wing political\, activist work and e
 xploring the social space. therefore i have decided to stop making traditi
 onal music and to focus musically on improvisation and electronic sound ge
 neration.\n\nthis allows me to combine some strong interests - for example
 \, exploring sounds\, computer programming\, electronic tinkering - and us
 e them for my artistic work. i play live with a small modular system as we
 ll as with self-developed digital\, computer-based instruments and control
 lers. in addition to ensemble \nimprovisation\, i am increasingly interest
 ed in solo performances. through my long time as a wind instrumentalist i 
 have become accustomed to always using my breath for articulation and dyna
 mic control. \nthat's why i usually use a breath controller for my electro
 nic performances.\nin this concert i expect to use an eurorack-modular in 
 combination with pure data & supercollider\n

 Oregon Trail\, and Lemonade Stand\, this talk explores how code\, ideology
 \, and play form power cycles—and how breaking them turns market logic int
 o creative resistance.\n\nhands-on session afterwards (from 5.30pm):\nhttp
 s://events.ccc.de/congress/2025/hub/de/event/detail/power-play-cycles-hand
 s-on\n\nSlides:\nhttps://docs.google.com/presentation/d/10aPPQov41A_9ySeQz
 uhuVZIn4arK4hLiqX6m82OYuRU/edit?usp=sharing\n\n–\n\nEconomic power hides i
 n rules. Early home-computer “market simulators” such as Hammurabi\, Orego
 n Trail\, and Lemonade Stand encoded entire ideologies of productivity\, s
 carcity\, and profit into a few dozen lines of BASIC. They taught us how t
 o play the economy — literally.\n\nBut what happens when players stop foll
 owing those rules and begin to rewrite them? This talk explores the power 
 cycles inside these classic games: loops of control between player\, progr
 am\, and system. By modifying code\, exploiting glitches\, and bending rul
 e sets\, we can expose how computational models reproduce economic dogmas—
 and how small hacks can turn libertarian fantasies into playful counter-ec
 onomies.\n\nThrough live demonstrations and short historical dives\, we’ll
  trace how the simple act of “cheating” becomes a tool of critique. Each i
 ntervention reveals a new feedback loop between code and ideology: where e
 very CPU cycle becomes a site of political power.\n\nCan a hacked simulati
 on still be fun? Can rewriting a game’s rules help us imagine different sy
 stems of value and exchange? Between nostalgia\, code archaeology\, and pl
 ayful subversion\, this session invites you to rethink what—and who—games 
 simulate when we let the power cycle run differently.\n

DESCRIPTION:\nA short sneak peek course to the International language Esper
 anto.\n\nEsperanto is a planned language\, initiated more than 130 years a
 go by Ludwik Lejzer Zamenhof. Nowadays it is spoken by more than 100 000 p
 eople worldwide.\n\nWe are people who for many years have been speaking Es
 peranto in our every day life. Its the language of our global circle of fr
 iends. As there are quite some parallelisms between the worldwide Esperant
 o community and the worldwide hacker scene\, usually there are some Espera
 nto speakers attending the big Chaos events.\n\nOf course we cannot give a
  comprehensive course about Esperanto\, but a few insights to the language
  and its community first hand.\n\nThe slides are available here: https://c

  please step inside. I trust you have all signed the waiver as instructed?
  Good. This visit will be of a long duration. Now\, please hand over your

 cary story but more of a cozy "Gruselgeschichte"\, which I think will fit 
 very nicely in the late hours after the talks.\n\n"A Visit to the Catacomb
 s of Dammtor" is based on the original work "A Visit to the Catacombs of V

 x\, no. 2\, Spring 2007)\, a literary review out of Eastern Illinois Unive

DESCRIPTION:Haecksen only.\n\nEs ist an der Zeit dafür zu sorgen\, dass wir
  mehr Engagement bei den Haecksen hinbekommen und das Wissen\, wie alles f
 unktioniert\, schneller verteilen. Lasst uns die Struktur dezentralisieren
  und rebooten.\nEinzelne Personen tragen viele Hüte. Die gesamte Struktur 
 wird durch wenige am Laufen gehalten. Gerade durch das Wachstum der letzte
 n Jahre und die damit verbundene Größe von ~1000 Haecksen sollte dazu führ
 en\, dass die Last verteilt wird – und nicht einfach mehr Aufwand auf weit
 erhin wenigen Schultern verteilt wird. Die Haecksen sind keine reine remot
 e Gruppe\, aber auch keine\, die nur offline tätig und sichtbar ist. Damit
  müssen wir einen guten Umgang finden\, damit beide Bereiche gut miteinand
 er funktionieren.\n\nWir sind viele und unsere Existenz ist wichtig\, Es i
 st an der Zeit die Haecksen neu zu strukturieren\; beginnend bei der Kommu
 nikation über die IT hin zu den Ortsgruppen. Sei es nun die Übernahme von 
 mehr Verantwortung durch eine Verteilung der Verantwortung auf die Ortsgru
 ppen oder einen anderen Ansatz. Es gibt einige Themen\, die wir einmal bea
 rbeiten müssen\, um diese großartige und wichtige Struktur weiter zu verbe
 ssern.\n\nLasst uns in diesem Workshop Verantwortung übernehmen und die be
 stehenden Strukturprobleme angehen und gemeinsam Maßnahmen zur Verbesserun
 g erarbeiten. Am Anfang soll eine Themensammlung stattfinden\, um zu erfas
 sen\, was es anzugehen gilt. Danach möchten wir in kleineren Arbeitsgruppe
 n die ersten möglichen Maßnahmen definieren. Alles folgt dem Ziel\, die Ha
 ecksen wieder voran zu bringen und zu einem Ort des Engagements zu machen 
 – in dem die Verantwortung von vielen getragen wird.\n

 ieren fallen oft erst auf\, wenn man selbst davon betroffen ist - oder abe
 r gelernt hat\, auf sie zu achten. Deshalb starten wir mit einer kurzen Se
 nsibilisierungsübung zum Thema Inklusion & Barrierefreiheit (nicht nur für
 s Thema Mobilität).\n\nAnschließend zeigen wir euch einen „sozialen Algori
 thmus“\, der Barrierefreiheit auf der Ebene von Stadtverwaltung\, Politik 
 und Aktivismus vorantreiben soll. Wir geben Einblick in die Entwicklung un
 seres Projekts a11y-Score\, welches vom Bundesministerium für Verkehr (BMV
 ) im Rahmen der mFund-Initiative gefördert wird.\n\nWeiter geht's mit eine
 r Einführung in die Wheelmap: einer offenen Karte (basierend auf OpenStree
 tMap)\, mit der Menschen weltweit Zugänglichkeit dokumentieren können - au
 ch für den vorgestellten Algorithmus.\n\nNach dem Workshop gehen / rollen 
 wir in Gruppen über das Gelände und probieren das ganze konkret vor Ort au
 s.\n\nZum Abschluss bleibt Zeit für Fragen\, Austausch und Ideen. Lasst un
 s gemeinsam die Welt zugänglicher machen - one data entry at a time! ✊\n\n

DESCRIPTION:\nAm 2. Juli 2024 kletterten wir unangemeldet auf das Ulmer Mün
 ster und platzierten dort auf einem riesigen Banner die Frage „Wäre Jesus 
 Klimaaktivist?“. Viele Kirchengemeinden in ganz Deutschland hängten darauf
 hin diese Frage selbst an ihre Kirchen und der Theologie-Professor Ruben Z
 immermann schrieb ein Buch über diese theologische Frage.\n\nDie These: Je
 sus hat sich laut Bibel immer für die Menschen eingesetzt\, die wenig hatt
 en. Die Klimakrise ist langfristig die größte Bedrohung für viele dieser M
 enschen. Wir glauben\, Jesus würde sich heute als Aktivist engagieren. So 
 wie er auch schon damals im Tempel Protest gemacht hat\, weil ihm die Komm
 erzialisierung nicht passte. Darum sollten sich Kirchengemeinden aus ihrem
  Glauben heraus für Klimagerechtigkeit und die Bewahrung der Schöpfung ein
 setzen.\n\n\n🧮\n

DESCRIPTION:\nOver the last two years\, Germany has engaged in systematic r
 epression of Pro-Palestine speech within its borders\, including home raid
 s for online speech\, border interrogations and device searches\, spurious
  criminal charges\, and arrests at protests for speech acts - often accomp
 anied by disproportionate use of force.\n\nSocial media monitoring\, as we
 ll as video surveillance of association and expression at protests play an
  important and ongoing role\, that becomes more problematic with the passa
 ge of Berlin's updated policing law providing for longer administrative de
 tention\, geofence warrants\, and the expanded use of facial recognition i
 n public spaces.\n\nIn this talk we briefly summarize events occurring in 
 Berlin and Frankfurt over the last two years as they pertain to digital su
 rveillance and repression. Amnesty and Civicus Monitor have spoken out abo
 ut Germany's repressions in this area\, and the latter has downgraded its 
 rating for Freedom of Expression accordingly.\n\nCome to find out what you
  can do to help push back against unconstitutional repressions of speech i
 n Germany\, and the role that NGOs and people with technical skills can pl
 ay.\n

DESCRIPTION:\nIn 1889\, peace activist and pioneer of international peace w
 ork Berta von Suttner published the novel ‘Lay Down Your Arms' in what was
  then the Austro-Hungarian Empire.\n\nIn 1929\, Erich Maria Remarque publi
 shed his work ‘All Quiet on the Western Front' in Germany during the Weima
 r Republic. Both remain important works of anti-war literature to this day
 .\n\nIn 1942\, Isaac Asimov wrote in ‘Runaround’ in the fictional handbook
  for robotics:\n\n"1. A robot may not injure a human being or\, through in
 action\, allow a human being to come to harm.\n2. A robot must obey the or
 ders given to it by human beings except where such orders would conflict w
 ith the First Law.\n3. A robot must protect its own existence as long as s
 uch protection does not conflict with the First or Second Law."\n\nAre you
  familiar with any of these works? All of them? Others? What aspects of th
 em are still relevant today? What can contemporary peace activism learn fr
 om them? Where is an update needed? What does peace activism look like whe
 n it incorporates modern machines\, AI and the digital sphere? What works 
 and initiatives do you know of that emerged after the Second World War and
  have had an impact on you?\n\nIn this session\, I would like to invite yo
 u to join me in thinking about how we can stand up for peaceful conflict r
 esolution and work for peace in our various professional disciplines and s
 pheres of life in 2026+ in the face of ongoing warmongering and armament.\
 n\nWhat does your current peace practice look like? What examples of succe
 ssful peace initiatives or anti-war art do you know? What is the current s
 tate of the transnational (and digitally connected) peace movement? And: H
 ow do we protect ourselves and others from repression and attacks by divis
 ive forces and warmongers?\n\nFor several years now\, I have been working 
 intensively on the topic of peace and have designed a seminar on this topi
 c this summer\, from which I am happy to contribute preliminary work and i
 nsights to this session\, if you are interested: https://www.udk-berlin.de

  recent years is simply immeasurable. \nWe would like to give you an overv

 ative methods does paragraph 129 allows? Who are the Nazis\, anyway? And w
 hy is solidarity important when Trump wants to destroy “Antifa”?\n

DESCRIPTION:\nAbstract: If you work involves sifting through and making sen
 se of large amounts of data\, we welcome you to a session on OpenAleph (op
 enaleph.org)\, where we can brainstorm (and commiserate) together. We will
  show practical examples of surfacing interesting leads from leaked data a
 nd explore falsely-held beliefs that stand in the way of investigators. Ma
 king sense of a large volume of data is marketed as being a textbook use-c
 ase for generative AI. We beg to differ.\n\nDescription: Making sense of l
 arge amounts of unstructured data makes users reach for prompting a chatbo
 t. Newsrooms and organizations we work with hope to “ask questions” in a c
 hat window\, instead of searching through their data. But these same users
  rightfully demand accuracy and deterministic results. If they don’t find 
 exactly what they are looking for\, they doubt the efficiency of the entir
 e software stack.\n\nOur experience\, at the Data and Research Center (dar
 c.li) with supporting research and investigations with algorithms and infr
 astructure led to insights about how to answer difficult questions in a de
 terministic way.\n\nThis session will walk the audience through several fe
 atures that surface names\, companies\, and other interesting data from la
 rge leaks. We will explore conundrums about search and deduplication featu
 res\, which pose difficult questions for investigators and programmers.\n\
 nThere are many falsehoods we tend to believe about our world. What is a n
 ame\, actually? What constitutes a country\, and who decides on that? How 
 do you search for words across several languages\, all at once? And how do
  you reveal hidden links in large volumes of data?\n\nAll these will be an
 swered without prompting a chatbot\, not even once!\n

DESCRIPTION:\nMost IT systems fail not because someone makes a mistake.\nTh
 ey fail because no one understands the overall behavior.\n\nThis SOS deals
  with emergent system effects:\nsituations in which correctly built compon
 ents together produce something\nthat no one planned\, modeled\, or contro
 lled.\n\nUsing real-world examples from IT infrastructure\, cloud dependen
 cies\, API designs\, AI usage\, update cascades\, and financial and identi
 ty systems\, we show\nhow technical decisions can create lasting stress an
 d conflict – often without a classic attacker\, without an exploit\, witho
 ut a clear trigger.\n\nIn line with the 39C3 motto “Power Cycles – Rethink
 \, Reboot\, Restart\,” the session asks the question:\n\nWhat do we need t
 o rethink before we restart?\nWhat can be rebooted – and what needs a fund
 amental rethink?\n\nThe term “sustainable war” is understood not in a mili
 tary sense\, but in a systemic sense:\n- as a state of permanent repurposi
 ng\,\n- overstretching\, and creeping destabilization of IT systems\,\n  w
 hich\n- drives innovation\,\n- undermines resilience\,\n- and generates so
 cial side effects.\n\nEspecially in times of global upheaval – geopolitica
 l\, technological\, social –\nautonomy\, dependencies\, and resilience mus
 t be reevaluated.\nNot as buzzwords\, but as concrete system properties.\n
 \nThe session is aimed at:\n- Administrators\, security engineers\, CISOs\
 n- Architects\, technical decision-makers\n- People from think tanks\, reg
 ulation\, and technology impact assessment\n

DESCRIPTION:Visual assembly/Workshop with Nika Dubrovsky\nUniversities have
  become debt traps. Education is no longer about learning—it's financial c
 ontrol dressed up as opportunity. Students graduate with crushing loans. P
 rofessors work precarious jobs. Administration consumes budgets that shoul
 d fund actual learning. Knowledge is sold\, credentialed\, gatekept.\n\nBu
 t what if we could reimagine this completely? Not reform universities—rede
 sign them from scratch.\n\nIn this workshop\, we're asking CCC participant
 s to collectively design the university of our dreams. Not the university 
 we think is "realistic" or "achievable within current constraints." The un
 iversity we actually want.\n\nHere are the questions:\n\nShould it be dist
 ributed or centralized? Fully virtual or partially offline? How do we use 
 open-source technologies to eliminate bullshit jobs\, administration\, and
  bureaucracy? How do we make education free\, accessible\, and democratic?
 \n\nCan a university exist without exams\, without filtering students\, ac
 cepting everyone who wants to learn? How do we build around open libraries
 —like David Graeber's music and book collections at davidgraeber.org—that 
 anyone can modify and contribute to? How does this become not an instituti
 on\, not a nation-state project\, but a community of experimenters distrib
 uted globally?\n\nUltimately\, this is about technologies—survival technol
 ogies. Social technologies. Poetic technologies.\n

DESCRIPTION:Matrix als Kommunikations-Backbone für die Verwaltung "??!!"\nA
  Reality Check Between Ambition\, Architecture\, and Everyday Practice\n\n
 When a citizen wants to communicate with public authorities\, the well-est
 ablished classics are still available: fax\, telephone\, and email — suppl
 emented by a growing number of inboxes\, portals\, and specialized messagi
 ng systems.\nClarity is not exactly their defining feature.\n\nIn Germany\
 , FITKO\, Saxony-Anhalt and Hamburg are attempting to bring some structure
  into this historically grown communication landscape through the ZaPuK pr
 oject.\nThe goal: fewer isolated solutions\, more structure\, more interop
 erability.\n(The fax is surprisingly persistent.)\n\nIn this session\, we 
 take a sober\, technical look at the following questions:\n\n* What can Ma
 trix realistically deliver as a *general-purpose communication fabric* for
  public administration?\n* Where does the protocol fit well from an archit
 ectural perspective?\n* Where does it become interesting?\n* And where doe
 s theory collide with federal realities\, domain-specific processes\, and 
 operational models?\n\nWe discuss the current state of projects\, discussi
 ons\, and recommendations followed by an honest reality check.\nNo marketi
 ng. No promises of salvation. But plenty of room for critical questions.\n

DESCRIPTION:Denise Frey macht elektroakustische Ambient-Musik – ruhig\, vie
 lschichtig\, atmosphärisch. Mit Saxophon\, MPC\, Effektgeräten und einem f
 einen Gespür für Klang formt sie in ihren Konzerten Klanglandschaften\, di
 e einladen zum Loslassen\, Lauschen\, Entspannen. Ihre Musik entsteht live
  – improvisiert\, organisch\, unmittelbar.\nSchon als Kind war Musik für s
 ie ein innerer Antrieb. Mit sechs begann sie am Keyboard\, mit 13 kam das 
 Saxophon – nur\, weil ein Junge\, den sie mochte\, es spielte und sie gena
 u so cool sein wollte. Sie blieb dabei. Erst wollte sie Schauspielerin wer
 den\, doch ein körperliches Handicap hinderte sie am Schauspiel – also stu
 dierte sie klassisches Saxophon. Nach Jahrzehnten intensiver Musikerfahrun
 g\, fand sie einen Weg zur freien Improvisation\, zur elektronischen Musik
  – und schließlich zu sich selbst.\n\n„Ich habe nichts gefunden\, was für 
 mich mehr Sinn ergibt als Musik“\, sagt sie. Musik war nie Plan\, sondern 
 Notwendigkeit – ein Mittel zur Selbstheilung\, zur Verbindung\, zum Ausdru
 ck. In der elektronischen Produktion fand sie nicht nur neue Klänge\, sond
 ern auch Freiheit: „Ich wollte nie abhängig sein. Schon mit 16 war mir kla
 r: Ich will eine Band sein – alleine.“\n\nHeute steht sie allein auf der B
 ühne – und füllt den Raum mit Tiefe. Ihre Sets sind verspielt\, meditativ\
 , manchmal technoid – immer offen für das Unerwartete. Was zählt\, ist die
  Erfahrung für sie und für ihr Publikum. „Ich habe immer eine gute Zeit\, 
 wenn ich spiele. Und ich wünsche mir\, dass andere das auch haben – dass s
 ie leichter rausgehen\, als sie reingekommen sind.“\n\nDenise Frey steht n
 icht da\, um sich zu inszenieren. Ihre Haltung ist leise\, aber klar. Es g
 eht ihr um Echtheit. Um Berührung. Um einen Raum\, in dem alles da sein da
 rf. Wer ihre Konzerte besucht\, erlebt Musik nicht als Performance\, sonde
 rn als Einladung.\nNeben ihren Solokonzerten spielt sie im ND Duo mit Nico
  Petry (Drums & Elektronik) und unterrichtet Saxophon\, Flöte\, Improvisat
 ion und Musikproduktion. Ihre Musik ist so vielfältig wie ihr Publikum – u
 nd ihr Anliegen immer dasselbe: Verbindung schaffen. Mit sich selbst. Und 
 mit anderen.\n

DESCRIPTION:THE SECOND DECADE \n\nBorn `78 in Germany Rob StrobE grew up an
 d being influenced with classical music\, swing and jazz in his childhood.
  \nHe early discovered the likes of Depeche Mode\, Michael Jackson\, Kraft
 werk and more early electronic music approaches. \nIn his late youth/early
  adult life he frequently travelled to Frankfurt attending nights at the O
 men. Those nights and weekends were filled with DJs like Sven Vaeth\, Dj R
 ush\, Chris Liebing\, G-Man aka Gez Varley\, Hardfloor and so many more\, 
 celebrating and transporting the spirit of those days! \nAfter the closing
  of the Omen in late 1998 he went on to clubs like u60311\, Tanzhaus West\
 , MTW and others and eventually started his career as professional (sound)
  technician and light jockey. \nAround the year 2002 he started music prod
 uction - mostly for personal fun and recreational purposes - but some reco
 rds and remixes have been released since then...some of this older work ca
 n still be found on his Soundcloud! \nSince then he developed his own comp
 any specialized on music studio technology\, room acoustic\, signal flow s
 chemes and studio furniture. Meanwhile his own studio transformed from a s
 mall Home Studio to a „room-in-room“ environment in the Logic Haus - the f
 ormer home of Harthouse\, Eye-Q and Snap! If he had to describe his musica
 l style and give it a name: it would be „DubHouseTechno with a pinch of De
 troit" \;) FastFoward: Year 2021 - after a 7 year break of releasing music
 \, Rob StrobE is back with releases on imprints like Lucidflow\, ASrecords
 \, Tantara\, Motech and numerous others! Rob used the time to do a major s
 wap from software based production over to the modular and hardware world 
 and the output speaks for itself! Enjoy his music and come pass for a visi
 t on his social media outlets and say „hello“! \n\nTHANKS FOR YOUR SUPPORT

 under his pseudonym Jan Dalvík\, stepping into the spotlight as a solo art
 ist.\nRenowned for his distinctive analog sound design\, Dalvík’s music st

 sistent\, sondern zunehmend als strukturierende Instanz genutzt\; eine sel
 bstgewählte Feedbackinstanz\, die auf der einen Seite Autonomie verspricht
  und andererseits zugleich neue Abhängigkeiten schafft. In unserem Worksho
 p  wollen wir gemeinsam darüber sprechen\, was diese Gegensätze für uns in
  der Praxis bedeuten.\nDie Softwareentwicklung gilt als Berufsfeld mit hoh
 em Maß an Autonomie\, kollaborativem Wissensaustausch und einer stark comm
 unity-getriebenen Lernkultur. Mit dem Einzug generativer KI verändern sich
  diese Strukturen grundlegend. Der spontane Austausch unter Kolleg:innen o
 der auf Foren wie Stack Overflow wird zunehmend durch den Dialog mit dem C
 hatBot ersetzt. In unserem Vortrag möchten wir die Konsequenzen daraus bel
 euchten. Zuerst stellen wir drei zentrale Ergebnisse unserer empirischen F
 orschung vor und werden diese anschließend analysieren und vor dem Hinterg
 rund arbeitssoziologischer Annahmen diskutieren.\n\nUnsere Studie basiert 
 auf einer digital-ethnografischen Analyse von Diskussionsbeiträgen auf Red
 dit\, in denen sich Softwareentwickler:innen offen über ihre Erfahrungen m
 it generativer KI austauschen. Daraus können wir zeigen\, dass Entwickler:
 innen KI-Systeme in drei Rollen verorten:\n\nKI als Werkzeug:\nDie KI wird
  gezielt eingesetzt\, um klar abgegrenzte Aufgaben zu erledigen. Ziel und 
 Vorgehen stehen fest\, die Kontrolle über Prozess und Ergebnis liegt volls
 tändig bei dem Nutzenden.\n\n\nKI als Assistenz:\nDie KI unterstützt als d
 ialogisches Gegenüber. Sie kann Ideen liefern und Alternativen vorschlagen
 \, aber Auswahl\, Bewertung und Einordnung der Inhalte bleiben beim Mensch
 en.\n\n\nKI als Proxy-Management:\nDie Entwickler:in weist der KI bewusst 
 eine leitende Rolle zu und überträgt ihr die Steuerung und Bewertung des e
 igenen Arbeitsprozesses.\n\nGerade in dieser letzten Form zeigt sich ein s
 pannendes Phänomen: KI als Feedbackinstanz ohne soziale Interaktion. Kein 
 Gatekeeping auf Stack Overflow\, kein „Wie\, das weißt du nicht?“\, keine 
 Unsicherheiten vor Kolleg:innen zugeben und keine endlosen Google-Suchen\,
  die ins Leere führen. Stattdessen ein vermeintlich privater und immer ver
 fügbarer SafeSpace\, in dem Unwissenheit nicht offenbart oder verurteilt w
 ird – und man immer eine Antwort bekommt. Viele beschreiben das als Gewinn
  an Autonomie. Andere berichten jedoch vom Gegenteil: Von wachsender Isola
 tion\, schleichendem Kompetenzverlust und einer neuen Form von Abhängigkei
 t.\nDiese Ambivalenz verstehen wir als Spannungsfeld zwischen technikvermi
 ttelter Selbstermächtigung und Kontrolle. Aus der Perspektive der Professi
 onssoziologie – in Anlehnung an Andrew Abbotts The System of Professions (
 1988) – werden berufliche Zuständigkeiten („jurisdictions“) stets neu ausg
 ehandelt. Dabei spielen technologische Entwicklungen eine zentrale Rolle\,
  weil sie bestimmen\, welches Wissen als Expertise gilt und wer es beanspr
 uchen kann. Für die Zukunft der Softwareentwicklung bedeutet dies vielleic
 ht: Weg vom kollektiven Wissensaustausch hin zu einer individualisierten P
 raxis.\n\nIn unserem Workshop möchten wir mit euch diese Dynamiken zwische
 n Autonomie und Abhängigkeit hinterfragen und diskutieren. Begegnet uns hi
 er eine neue Form von KI-(Selbst)-Kontrolle\, jenseits klassischer Hierarc
 hien? Und welche Folgen bedeutet das für unser Selbstverständnis\, Lernpro
 zesse und die soziale Verankerung professioneller Programmierarbeit?\n

DESCRIPTION:Join this session to gain a deeper understanding of the work of
  the Free Software Foundation Europe (FSFE) and how the organisation empow
 ers users to take control of technology. We will explore FSFE’s wide range
  of activities — from advocacy and policy work at the European level to pr
 actical initiatives such as “Public Money? Public Code!”\, which promotes 
 publicly funded software being released as Free Software. Explore how we f
 ight for Device Neutrality and how we want to spark children's interest in
  coding.\n\nThe session will also highlight FSFE’s legal support efforts\,
  community-building activities\, and public awareness campaigns that help 
 ensure technology remains accessible\, transparent\, and shaped by its use
 rs rather than by restrictive corporate or governmental control.\n

DESCRIPTION:\nSociety is not built for neurodivergent minds. Discrimination
 \, exclusion\, and institutional bullying are not individual misfortunes\;
  they are systemic failures. I will share insights from my own journey and
  the practical tools I’ve developed to fight back against these structures
 .\n\nBut individual resilience isn't enough. We are using this session at 
 39C3 to found a community that refuses to accept institutional discriminat
 ion. Our goal is to organize peer support\, expose systemic abuse\, and bu
 ild a solid infrastructure for mutual aid.\n\nThis is not a lecture. Toget
 her\, we will define how this collective will operate. Bring your anger\, 
 your ideas\, and your skills. Let’s hack the structures that try to shut u
 s out.\n

DESCRIPTION:\nThe ‘Digital Omnibus’ is a collection of proposals from the E
 U Commission to deregulate existing digital laws\, which are actually ther
 e to protect people. The General Data Protection Regulation (GDPR) and the
  AI Regulation (AI Act) will be watered down under the pretext of supposed
  reduction of bureaucracy .\n\nInstead of helping ‘small and medium-sized 
 enterprises’ or start-ups in Europe\, as promised\, it is primarily US big
  tech giants that would benefit\, and the European Commission's proposals 
 read like an implementation of the Trump administration's wish list.\n\nTh
 e session is intended to be a networking meeting for civil society NGOs an
 d individuals to stop the omnibus bill.\n\nThis session follows a talk on 
 the topic on Day 1\, which we therefore recommend:\nhttps://events.ccc.de/

DESCRIPTION:Probiotic making & cooking workshop\n[To secure spot on this wo
 rkshop please sign in here.](https://dud-poll.inf.tu-dresden.de/pc_39c3/)\
 n\nProbiotic cooking is hands on workshop where we use high quality probio
 tic or by fermentation prepared ingredients creating variety of dishes. Th
 ere are two main topics. One is to "discover" how much better dishes can b
 e when you are using really high quality ingredients. The other is to shar
 e recipes and tricks to make these amazing dishes. Imagine for example mak
 ing soup from kimchi\, kimchi jjigae (김치찌개) or kimchi-jeon 김치전\, dressing 
 for salad using cidre vinegar aged for five years in oak barrel mixed with
  mirrabelle syrup made at 2019 ccc camp\, soy sauce infused at cold with s
 hiso ...\n\nFhb will have a decent amount of good stock\, if you can bring
  something good please do so\, either for the workshop or for sharing and 
 exchange.\n\nThis workshop is based on "donation at your will no one turne
 d away for lack of funds". Part of the workshop benefits goes towards fhb 
 budget and hopefully larger part towards Algoldor's pocket to cover partic
 ipation costs at 39c3 event and if some extras are accumulated\, then towa
 rds current and future fermentation projects.\n

 ease do sign in advance\, you can just show up before the event but we are
  very likely going to be full for this one (like three times overbooked). 
 If you can bring cheese which you made by yourself that would be great! Of
  course some specific local or extraordinary cheese/s or other related con
 diments like sun dried tomatoes\, good quality olives\, mustards\, wine al
 l would be appreciated. If you are bringing cheese please do label it well
  with at least it's name and type of milk used\, your nick or name/contact
  would come handy too. The best would be of course to add short descriptio
 n to our wiki (please check the sample). Still please sign in in advance! 
 FHB will be getting some high quality cheeses to offer basic selection wit

DESCRIPTION:Der verlängerte Atem pres. Ghost Processes\n\nSeit 2020 sendet 
 Der verlängerte Atem regelmäßig auf HALLO:Radio und tourt mit Gastauftritt
 en auf Festivals und Veranstaltungen in und um Hamburg. Als offenes Radiol
 abor zwischen Musik\, Redebeiträgen und thematisch passenden Audio-Snippet
 s\, verweben die Vinyl-DJs\, Künstlerinnen und Radiomacherinnen Fiona Gras
 sl\, Jil Lahr und Martin Ramacher analoge Klänge\, Stimmen und Gedanken zu
  thematischen Sendungen.\n\nFür den 39C3 fährt Der Verlängerte Atem das Sy
 stem herunter - und wieder hoch. Und findet dazwischen: Prozesse ohne Besi
 tzer\, Threads ohne Aufgaben\, Routinen\, die längst beendet sein sollten 
 und doch weiterlaufen. Geisterprozesse flüstern im Hintergrund\, aktualisi
 eren sich selbst\, verlieren den Takt oder schlafen zu tief\, um je zurück
 zukehren. Zwischen knisterndem Vinyl\, digitalem Summen\, Glitches und ver
 spielten Redebeiträgen entstehen live Sound-Landschaften\, in denen nichts
  ganz verschwindet - und alles wiederkehrt. Spooky.\nhttps://soundcloud.co

DESCRIPTION:Dj Set\nNɨxe moves quietly beneath the surface of the German un
 derground. She has been part of Berlin’s slow sound since its early waves\
 , shaping downtempo spaces with a calm and steady presence. Her sets drift
  between pulse and atmosphere\, guided by a deep intuition for timing and 
 tone. To hear Nɨxe play is to follow a subtle current. She doesn’t push or
  perform. She invites\, leads\, and lets the music do the rest. Her sound 
 has travelled across continents\, yet always returns to something essentia
 l: classy grooves that breathe\, rhythms that open space\, and a gentle pu
 ll toward introspection. It’s all held together by a distinct sensitivity 
 to mood and movement — one that doesn’t ask for attention\, but quietly ea
 rns it. Beneath it all\, there’s a soft devotion to acid lines and psyched
 elic textures. Subtle. Never loud. Always felt.\n

DESCRIPTION:A beginner-friendly\, hands-on workshop where you build a worki
 ng particulate matter air quality sensor using off-the-shelf parts. Learn 
 the basics of IoT environmental monitoring and share your data online with
  Sensor.Community.\n# Build Your Own Air Quality Sensor\n\nAir pollution a
 ffects many people’s daily lives\, not only those living near industrial c
 entres. In Ireland\, official air quality monitoring relies on a limited n
 umber of sensors\, so local and short-term pollution sources can be missed
 . In this 90-minute\, hands-on workshop\, you’ll build your own particulat
 e matter (PM2.5) air quality sensor using a kit of off-the-shelf parts\, t
 hen connect it to the Internet so you can view and share the data.\n\n## S
 ensor.Community\n[Sensor.Community](https://sensor.community/) is an open\
 , global citizen science network where people build low-cost sensors and s
 hare environmental data. Once your device is online\, it can publish readi
 ngs so you can track trends over time and compare data across different lo
 cations.\n\n## What You’ll Learn\nDuring the workshop\, you’ll assemble a 
 working PM2.5 air quality sensor and get it online. We’ll cover the basics
  of IoT devices\, local data collection\, and how to publish readings to S
 ensor.Community. You’ll also learn what the numbers mean\, what these sens
 ors are good for\, and where their limits are.\n\n## Materials\nYou’ll wor
 k with:\n- ESP8266 board\n- SDS011 particulate matter sensor (PM2.5 and PM
 10)\n- BME280 sensor (temperature\, humidity\, air pressure)\n- USB cable\
 n- Jumper wires\n- Plastic tube (air inlet)\n\n## Requirements\n- A device

DESCRIPTION:\nThere is a virtual world that we visit every day. It has bill
 ions of inhabitants and billions of places. But\, whenever we go\, there i
 s nobody. Just the messages they left. We read our daily online newspapers
  while many are doing the same. We are browsing the same content - but we 
 are still alone. If only we could see the other people browsing the same c
 ontent at the same time. They might be interested in the same things right
  now.\n\nImagine the real world without all the people on the streets. Str
 eets and places\, shops\, cafés\, libraries\, deFV\nvoid of people. That's
  the Internet\, the Web as it currently exists. Always has been like that 
 and we got used to it. But we wanted more. We wanted social interactions. 
 We got Social Networks and they turned into meme feeds and brain rot. That
 's not what we asked for.\n\nWe asked for people\, real people. And they a
 re already there. What if we  make them visible to each other? Then\, ad-h
 oc communities can form directly at the content. Communities of like-minde
 d people\, interested in the same things.\n\nAll we need is a federated so
 cial layer that cannot be owned\, because it is decentralized as the Web i
 tself. An infrastructure of some existing chat protocol in the spirit of t
 he Fediverse or XMPP.\n\nA new way to communicate everywhere\, not just in
  Social Media silos\, not after giving up your profile. We want to talk to
  the people we meet wherever we go. We want to reclaim the Web.\n\nHere is
  how we do it\n\nCreating a decentralized social layer independent of Soci
 al Media silos.\n

DESCRIPTION:\nAbstract: Relationship Anarchy is a guiding principle that ho
 ld the promise for us to prefigure the future. This session will start off
  by defining Relationship Anarchy. It will then nest this definition in th
 e context of our current situation (socially\, politically\, technological
 ly). Finally\, we will look at technologies in a wider sense and investiga
 te whether they are nurturing or hostile towards the prefiguration of Rela
 tionship Anarchy.\n\nDescription: Relationship Anarchy is a form of livabl
 e anarchy. It follows in the steps of anarchy\, in that it rejects illegit
 imate authority and nurtures personal and collective autonomy and agency. 
 Livable anarchy opens up the public space for folx to participate actively
  in shaping how they wish to live and self-represent their desire and iden
 tity. It is rooted in solidarity and a respectful attitude towards otherne
 ss.\n\nIn this talk\, we explore the ways in which technology shapes our a
 bility to practice Relationship Anarchy\, as a form of livable anarchy. We
  start off by acknowledging that our use of technology shapes what we can 
 do\, perceive and imagine. In this sense\, we can categorize technologies\
 , in a broad sense\, as either hostile towards Relationship Anarchy\, or a
 s nurturing towards it.\n\nThe basis of this discussion is going to be a d
 efinition of Relationship Anarchy that catileptic\, the speaker\, offers i
 n their writing: "Relationship Anarchy is honoring alterity while making o
 ne's self subject to others".\n\nThis presentation is loosely based on thi
 s essay: https://catileptic.tech/posts/relationship-anarchy-technology/ .\

DESCRIPTION:\n(While this abstract is in English\, this workshop will be he
 ld either in English or German\; depending on who wants to participate!)\n
 \nProgramming is not only a useful competency and oftentimes fun\, but als
 o a sort of “cultural technique” of our ever-expanding community. This wor
 kshop is intended as a first introduction to (Python) programming for abso
 lute beginners. While C3 is traditionally a 'tech/hacker conference'\, mor
 e and more people without a programming background attend – as far as I'm 
 concerned\, this is awesome!\n\nWhile you certainly don't have to be a 'co
 der' to be a part of Congress (or to be a hacker)\, programming is still f
 un\, wonderfully creative\, and also an extremely valuable skill. Don't be
  afraid to give it a go!\n\nOf course\, by the end of this 90-minute works
 hop\, you will not be a programmer. You will\, however\, have attempted a 
 deep dive into (Python) programming\, learned some basics\, and set yourse
 lf up for further learning (if you choose to do so). Furthermore\, we will
  explore why it is still worthwhile to learn programming in a world that i
 s seeing increased LLM usage – especially in the domain of software develo
 pment.\n\n## Target Audience and Required Previous Knowledge\n\nThis is NO
 T a session for experienced developers who want to learn Python. This sess
 ion is intended for beginners with little to no experience programming! Mo
 tivated children and young hackers are more than welcome\, but it will be 
 a stretch.\n\nNo previous knowledge and/or technical expertise is required
 !\n\n## Learning Objectives\n\nFrom a learning perspective\, after the ses
 sion\, participants will be able to …\n\n* describe what programming essen
 tially is about.\n* name and describe some basic programming terminology.\
 n* define requirements and design simple software.\n* model simple problem
 s in terms of data structures and basic algorithms.\n* write basic scripts
  in Python in order to solve specific problems.\n* describe the role of LL
 Ms in modern software development.\n\n## About Me\n\nMy Name is Ingo\, and
  I am currently responsible for Digital Education and Educational Technolo
 gy at the University of Cologne. Relevant to this session\, I have a backg
 round in both education and computational linguistics. My love for Python 
 stems from my work as a (computational) linguist and various projects I've
  been involved with. :)\n\n## Format\n\nThis session will be a 90-minute “
 code-along” workshop. We will be looking at some fundamental concepts in t
 heory and\, together\, write some code.\n\n## Technical Requirements\n\nIf
  you want to participate actively (i.e.\, code along)\, you should bring a
  device that is capable of running a modern browser and has Internet acces
 s. Being able to type comfortably is also recommended \;). Alternatively\,
  any device capable of running Python 3.10+ (ideally in a Jupyter Notebook
 ) will do just fine!\n\n## Material\n\nAfter the session\, I will provide 
 all materials\, including some selected additional resources. All material
 s will also be provided via this page.\n\nThe material\, including the sli
 des\, is available via [GitHub](https://github.com/IngoKl/39c3-python-prog
 ramming-for-absolute-beginners).\n\nPs. This is a slightly updated version
  of the workshop(s) I gave at previous iterations of congress.\n

DESCRIPTION:\n‘New smoke detectors spy on tenants – and they have to pay fo
 r it’ was the headline in Stern magazine on 5 November 2024. The ‘smart’ s
 moke detectors referred to in the article have sensors that can detect fir
 es and also measure ‘personal climate data’\, transmitting it wirelessly [
 2\, 3]. Consumer advocates have warned of infringements on personal rights
  [4\, 5]\, and the topic has also sparked heated discussions within the co
 mmunity [6]. However\, Techem claims that neither landlords nor they can d
 etermine which rooms someone is currently in. It is also not possible to t
 rack whether people are leaving the apartment or coming home” [3]. [3].\n\
 nWorkshop schedule:\nIn about 10 to 15 minutes\, we will introduce the top
 ic of simple sensor data in the smart home. We will present examples of si
 mple sensors from our research and explain how they were created using our
  sensor kit [7–9].\n\n\nThe second part is a joint 'data guessing game'. W
 e will examine selected data traces that could have been generated by smar
 t smoke detectors\, such as the 'Multisensor Plus'\, and similar devices*\
 , and attempt to collectively analyse the data and classify it.\n\nThe fin
 al 20–25 minutes of the workshop will be reserved for reflection.\nHow mea
 ningful is simple sensor data from the home?\nWhat impact can this sensor 
 data have on privacy?\nHow should we deal with it?\n\n[1] https://www.ster

DESCRIPTION:\nHow are Antifa-Ost\, the war in Ukraine\, Antifa = terrorist 
 group\, an American despot\, and the bank accounts of German left-wing ant
 i-repression structures connected?\nThis fall\, several political actors i
 n Germany were affected. Among them were the anti-repression structures AB
 C Dresden and Rote Hilfe e.v: Our bank accounts were closed and several ba
 nks refused to open new ones. The reason? No official reason has been give
 n to us so far. However\, when we look at these events against the backdro
 p of the ongoing criminalization of anti-fascism and the classification of
  anti-fascists from Germany as terrorists by the US\, a political motivati
 on seems likely. This development is worrying and highlights the urgency o
 f taking action against the ever-increasing shift to the right.\n\nAfter a
  brief update on the situation of affected groups and the political contex
 t in which debanking is taking place in Germany\, we want to explore how w
 e can respond to the current situation and develop a common perspective fo
 r action. \nOur goal: to make anti-repression structures capable of action
  again in the current times!  Because we need them all more urgently than 
 ever!\n\nWe would like to discuss the following topics in groups:\n- Netwo
 rking among GLS members / GLS cooperative\n- Alternative and decentralized
  payment options. Creating independence from banks?\n- Gathering informati
 on\, bringing transparency to commercial lists (OFAK and Worldcheck)\n- Le
 verage and pressure options on Bafin/authorities. Which actors are involve
 d? Who creates sanctions and terror lists?\n

DESCRIPTION:The Four Freedoms (defined ~40 years ago) and the Four Opens (~
 15 years ago) for Open Source provided canonical definitions for what are 
 the cornerstones of Open Source Software communities today. While the etho
 s still applies today\, the cultural norms that blossomed to put it into p
 ractice are from an era with different challenges.\n\nTo build a better wo
 rld\, we need to both keep and protect the value system of the Four Freedo
 ms and Four Opens. To do that\, we need to re-assess our risk and threat m
 odels to balance that allows beautiful minds to flourish as well as introd
 uce responsible friction to prevent harm from coming to them.\nThe state o
 f the internet\, c 1990:\n\n* Limited\, opt-in connectivity: people had to
  both have access to a computer and that computer had to have access to th
 e internet.\n* Tooling required some in-industry knowledge to be able to r
 un and use\, not only for development but also for communication.\n* Open 
 source was a young movement. The "common source" was proprietary.\n\nThe s
 tate of the internet\, c 2025:\n\n* Always online\, might-not-even-be-to-o
 pt-out connectivity: devices are almost always collecting and transmitting
  data\, including audio/visual\, in some cases even if "turned off".\n* Ea
 sy to use tooling has made it easier for everyone to come together. The pe
 rvasiveness of technology also means that most people\, of any background\
 , can easily access other people in the thousands or even millions.\n* Ope
 n source is common\, accessible\, and matured. A $9 **_trillion_** resourc
 e. Yes\, **_trillion_**.\n\nThese three significant changes drastically ch
 ange the threat model for OSS communities. In the beginning\, someone had 
 to have both knowledge and resources to harm or otherwise compromise a com
 munity of developers. Now\, anyone with a grudge can make a bot army with 
 seamless integrations and gracious freemium tiers for AI/LLMs. Likewise\, 
 when open source was small\, the "who" who would be motivated to harm and 
 otherwise disrupt those communities was limited. Now there is both massive
  social and economic benefit to harm and disrupt. This means that risks an
 d threats now still include the motivated and resourced **_with the additi
 on of_** those who are scarce in both.\n\nWe need to come together to buil
 d new organizational threat models that account for how this consequence h
 as posed new risks to our communities. With care and attention to detail\,
  we can introduce responsible friction that will protect our communication
  infrastructure\, the lifeblood of what allows open source to grow.\n\nThe
 re will also be a workshop with this presentation\, with the outcome of cr
 eating an ongoing working group dedicated to helping OSS Foundations of al
 l sizes protect their communities.\n\nThere will be a workshop about the s
 ame topic on 12.30\, Day 4: [https://events.ccc.de/congress/2025/hub/de/ev

DESCRIPTION:Encoding isn’t just for machines — it’s how humans shape meanin
 g. This talk traces 35 years of hacking text through the Text Encoding Ini
 tiative (TEI)\, a community-driven\, open-source standard for describing t
 he deep structure of texts. We’ll explore how TEI turns literature\, resea
 rch\, and even hacker lore into machine-readable\, remixable data — and ho
 w it enables minimal\, sustainable self-publishing without gatekeepers. Fr
 om alphabets to XML and the Hacker Bible\, we’ll look at text as a living 
 system: something we can read\, write\, and hack together.\nComputers can’
 t do much without encoding. They need ways to turn bytes into symbols\, wo
 rds\, and meaning — to make text readable for both humans and machines. Bu
 t encoding isn’t just for machines. Humans also encode: we describe\, stru
 cture\, and translate our thoughts into text. And while the number of text
  formats seems endless (and keeps growing)\, that’s not a bug — it’s a fea
 ture. Diversity in encoding is how we learn what works and what doesn’t.\n
 \nLong before ASCII tables or Unicode\, text encoding already existed — in
  alphabets\, printing presses\, and typographic systems. Every technology 
 of writing has been a way of hacking language into matter: from clay table
 ts to lead letters\, from code pages to Markdown. Each era brings new form
 ats and new constraints — and with them\, new genres\, new rules\, new cul
 tural codes. Think of poetry and protocol manuals\, fairy tales and README
  files\, the Hacker Bible itself — all shaped by the tools and conventions
  that carry them.\n\nSo here’s the question: can we encode not only what w
 e see\, but what we mean? Can we capture a poem’s rhythm\, a play’s voices
 \, or the alternate endings of a story — and do it in a way that’s open\, 
 remixable\, and machine-readable?\n\nTurns out\, yes — and the solution ha
 s existed since 1988. It’s called the Text Encoding Initiative (TEI)\, a l
 ong-running open-source standard that lets you describe the structure\, se
 mantics\, and context of texts using XML. You can think of it as a humanit
 ies fork of hypertext — an extensible markup language for everything from 
 medieval manuscripts to memes.\n\nTEI is more than a format: it’s a collab
 orative\, living standard maintained by an international community of rese
 archers\, librarians\, and digital humanists. It evolves with the world — 
 adding elements for new text types (like social media posts) and for chang
 ing cultural realities (like non-binary gender markers). It embodies open 
 science principles and keeps publishing in the hands of its creators.\n\nY
 ou don’t need a publisher\, a platform\, or a big server farm. Just an XML
 -aware text editor\, a few lines of CSS\, and maybe a Git repo. From there
 \, you can transform your encoded text into websites\, PDFs\, e-books — or
  share it directly in its raw\, readable\, hackable form. It’s sustainable
 \, transparent\, and low-energy. It even challenges the academic prestige 
 economy by making every individual contribution visible — from editors to 
 annotators to script writers.\n\nIn this talk\, we’ll look at text as code
  and code as culture\, from alphabets to XML\, and explore how TEI can be 
 a tool for hacking not machines but meaning itself. We’ll end with a pract
 ical example: a TEI-encoded page of the first Hacker Bible — because our o
 wn history also deserves to be archived\, shared\, and forked.\n

  series of transistors\, and their physical state represents 1's and 0's\,
  original EPROM memory could be erased via the utilization of UV light\, i
 n preparation for flashing new memory.\nNaturally\, whilst useful\, this h

 that does laser fault injection\, can detect hardware malware\, detect sup
 ply chain chip replacements\, and delve into the realm of laser logic stat
 e imaging.\nStored memory in hardware has had a long history of being infl

 nions are that laser (or light) based hardware attacks\, are something tha
 t only nation state actors are capable of doing\; due to both limitations 
 of cost in tooling as well as personnel expertise required. Currently\, so
 phisticated hardware labs use expensive\, high frequency IR beams to penet
 rate the resin.\n\nThis project demonstrates that with a limited budget an
 d hacker-and-maker mentality\, similar results can be obtained at a fracti
 on of the cost\, from the comfort of your home or garage. With the modific
 ations of an opensource low-cost microscope\, addition of a home-built bea
 m splitter and interchangeable diode laser\, it has been shown that consum
 er-grade diodes are capable of producing results similar to the high-cost 
 variants\, such as the YAG lasers.\n\nOne example of results includes intr
 oducing affordable avenues to conduct laser-based fault injection\, via th
 e usage of such budget-friendly tooling. We are opening the study of these
  low-level hardware attacking methodologies to more entry-level security t
 esters\, without the need for hundreds of thousands of dollars in startup 
 capital.\n\nBy leveraging more affordable technology alternatives\, we hav
 e embarked on a mission to uncover hardware malware\, detect supply-chain 
 chip replacements\, and delve into the realm of laser-logic-state imaging.
  Our approach integrates optics\, laser selection\, and machine learning c
 omponents.\n

DESCRIPTION:Keeping old projects working can be an uphill battle.  This tal
 k explores how the laser tag system Q-Zar (Quasar in the UK) has been kept
  alive since the company behind it failed in the 90s.   The challenges enc
 ountered\, the lessons learnt\, and how those can be applied to our own fu
 ture projects to maximise the project lifetime.\nLooking at the effects of
  obsolescence in the context of a laser tag system from the 1980s Q-Zar (Q
 uasar in the UK)\, what needed to happen to keep it going to enable people
  to continue playing.  What lessons we can learn from that and some good e
 xamples from other projects\, and how that can be applied to our own proje
 cts.\n\nThis talk covers the electronics involved in the laser tag system\
 , why the continued availability of components has varied a lot.  The need
  to develop new computer software that continues to work years later.  The
  way the physical equipment can have its life extended.\n\nTopics covered 
 range from electronics design through to software coding and onto physical
  unit repair. A look at the tooling created to help maintain\, support and
  repair the laser tag packs.  The challenges Covid-19 created and how thin
 gs were rapidly pivoted to enable continued playing in challenging times.\
 nThis is about how we all can make simple decisions that help build someth
 ing that will last the maximum time possible with the least amount of effo
 rt.\n

DESCRIPTION:I wanted to design beautiful header diagrams and ASCII tables s
 uitable for stitching on throw pillows\, but found existing tools for cros
 s-stitch design to be all wrong. I made my own set of command-line tools f
 or building this chunky\, pixelated visual art. If you've never seen a cro
 ss-stitch sampler that had bitrot\, this talk will fix it.\nDesigning cros
 s-stitch patterns\, I got frustrated with all the programs which expected 
 me to click around a canvas setting individual pixels. I wanted a cross-st
 itch design software suite that I could drive with a Makefile\, which coul
 d give me an interactive interface for stitching or compile them to PDF. I
 n short\, I wanted to say `echo "shutdown -h now" | embellish --border | e
 xport pattern --pdf` and get a design worthy of stitching on a pillow.\n\n
 So\, I made the thing I wanted. I'll discuss the many yak shaves along the
  way (proprietary file format reverse-engineering\, OAuth2\, what 'color' 
 even means\, unikernel hosting\, and more). I'll talk a bit about the joy 
 of making something so you can make something\, and how it feels to craft 
 software that is unapologetically personal.\n

DESCRIPTION:The end of free support for Windows 10 was 14 October 2025. Wel
 l\, sort of. Microsoft moved the date to 2026\, one more year the FOSS com
 munity can introduce users to sustainable software. 14 October is also KDE
 's birthday\, International E-Waste Day\, with International Repair Day fo
 llowing on 18 October. The irony is deep\, but what is not ironic is that 
 millions of functioning computers will end up becoming security risks or d
 iscarded as e-waste. This means manufacturing and transporting new ones\, 
 the biggest waste of all: hardware production accounts for over 75% of a d
 evice's CO2 emissions over its lifespan.\n\nThe FOSS community had an oppo
 rtunity and we took it! In 2024\, KDE Eco's Opt Green project began a glob
 al\, unified campaign across FOSS and repair communities to upgrade unsupp
 orted Windows 10 computers to Linux. We held BoFs at SFSCon\, CCC\, and FO
 SDEM. We thought big and acted boldly. In this talk End Of 10 contributors
  will discuss the campaign\, what has worked and what the challenges have 
 been\, and how FOSS provides a solution to software-driven resource and en
 ergy consumption.\nThis is a talk about digital sustainability and the rol
 e software plays in hardware longevity. At the 38C3\, the End Of 10 campai
 gn held a workshop to co-ordinate contributions across FOSS communities. M
 any people currently involved started contributing after this workshop\, i
 ncluding 2 of the 3 presenters.\n

DESCRIPTION:We explore what happens when Europe’s ambitious data access law
 s meet the messy realities of studying major digital platforms. Using YouT
 ube as a central case\, we show how the European Union’s efforts to promot
 e transparency through the GDPR\, the Digital Services Act (DSA)\, and the
  Digital Markets Act (DMA) are reshaping the possibilities and limits of i
 ndependent platform research.\n\nAt the heart of the discussion is a parad
 ox: while these laws promise unprecedented access to the data that shape o
 ur digital lives\, the information researchers and citizens actually recei
 ve is often incomplete\, inconsistent\, and difficult to interpret. \n\nIn
  this talk\, we take a close look at data donations from over a thousand D
 anish YouTube users\, which at first glance did not reveal neat insights b
 ut sprawling file structures filled with cryptic data points. Still\, if t
 he work is put in\, these digital traces offer glimpses of engagement and 
 attention\, and help us understand what users truly encountered or how the
  platform influenced their experiences.\n\nThe talk situates this challeng
 e within a broader European context\, showing how data access mechanisms a
 re set up in ways that strengthen existing power imbalances. Application p
 rocesses for research data vary widely\, requests are rejected or delayed 
 without clear justification\, and the datasets that do arrive frequently l
 ack the granularity required for meaningful analysis.\n\nYet the picture i
 s not purely bleak. Citizens\, researchers\, and civil society already hav
 e multiple legal levers to demand greater transparency and accountability.
  The fundamental question is no longer whether democratic oversight is pos
 sible\, but how we can use the tools at hand to make it real.\n**Talk Desc
 ription**\nIn this talk\, we explore what happens when the European Union’
 s data access laws meet the practical realities of platform research. The 
 talk opens with a shared introduction\, where David and LK set the stage: 
 why social media platforms like YouTube matter for democracy and what the 
 EU has done to make them more transparent.\n\nLK will then provide a short
  introduction into the legally mandated ways we can currently use to acces
 s platform data: from the GDPR’s right of access\, the research data acces
 s provisions in the DSA\, to the portability obligations into the DMA. But
  access is not the same as insight\, a lesson David learned the hard way. 
 Along with his team he invited over a thousand Danes to make use of their 
 GDPR-right to their own data and donate their YouTube watch histories\, se
 arches\, subscriptions and comments. Using the DSA\, the team then obtaine
 d meta-data on the millions of videos the data donors had interacted with.
  The goal: Seeing what the digital data traces YouTube collects from its u
 sers can tell us about the platform’s effect on people’s lives and society
 . Are the data carrying indicators of polarization\, loneliness\, politica
 l extremism or any of the numerous other ails of society that YouTube has 
 been suspected to cause? However\, the data are difficult to get a hold of
 \, messy\, not properly annotated\, and parsing them requires an almost ar
 cheological mindset. Together\, we will peek behind the Youtube curtain\, 
 shine a light on what platform data actually looks like\, and sketch out w
 hat can and cannot be learned from them.\n\nAll around Europe\, researcher
 s are currently facing similar challenges\, parsing cryptic user and platf
 orm data from Facebook and TikTok to porn sites and Zalando. The platforms
  implement the data access laws to achieve minimal compliance but not to p
 rovide meaningful transparency. Data gathered by the DSA40 Data Access Col
 laboratory shows that application forms vary widely\, researchers are reje
 cted for non-compliant reasons\, and applications artificially stalled. Ot
 her researchers have shown that the data received through some of the APIs
  is incomplete and inaccurate. In short: there is a lot of space for impro
 vement. But we do not need to wait for investigations into platform compli
 ance to conclude.. The basic conditions for democratic oversight have been
  set\, which means that theoretically various legal ways into the platform
 s exist for citizens\, researchers and civil society. The question that re
 mains is which levers to use to practically realise as much of this potent
 ial as possible.\n\n**About the Presenters**\nDavid Wegmann is a PhD stude
 nt at Aarhus University\, Denmark. He researches social media and its soci
 etal effects using data science. As part of DATALAB\, he led the analysis 
 of donated data for “Data donation as a method for investigating trends an
 d challenges in digital media landscapes at national scale: The Danish pop
 ulation’s use of YouTube as an illustrative case” by Bechmann and colleagu
 es (2025).\n\nLK Seiling coordinates the DSA40 Data Access Collaboratory\,
  where they research the implementation of the DSA’s data access provision
 s. At the Weizenbaum Institute Berlin\, they are also looking into researc
 h engineering and data access as well as technologically mediated risks fo
 r individuals\, society\, and science.\n

DESCRIPTION:What would it look like to build financial infrastructure for s
 olidarity rather than speculation? While blockchain technology has largely
  been captured by libertarian and extractive market logic\, it certainly d
 oes not need to be that way.\n\nIn this talk\, we'll explore Solidarity Pr
 imitives\, development and architectural design patterns designed to forge
  economic solidarity between individuals and collectives. Drawing from our
  work at Bread Cooperative and research I've documented through my podcast
 \, The Blockchain Socialist\, we'll examine concrete examples like the BRE
 AD community token\, savings circles implementation\, and the Solidarity F
 und mechanisms that enable participatory funding without relying on ventur
 e capital or traditional financial intermediaries.\n\nWe'll discuss how th
 ese primitives address a critical gap: the technical and coordination barr
 iers that have historically made alternative economic models difficult to 
 implement at scale. From worker cooperatives to mutual aid networks\, the 
 infrastructure simply hasn't existed. Peer-to-peer technologies can change
  that but only if designed with solidarity\, not profit maximization\, as 
 the core principle.\n\nThis talk is for anyone interested in the practical
  dimensions of building a post-capitalist economy: what does it actually l
 ook like to write code for collective autonomy? How do we ensure decentral
 ized systems serve communities rather than concentrating power?\nThis talk
  will last approximately 15 to 20 minutes followed by Q&A discussion for t
 he rest of the time.\n

  the Critical Decentralization Cluster assembly during 39C3 is a progress 
 report on Offworld Voyage\, a Space Analog Research project dedicated to t
 he design of environmentally sustainable interplanetary exploration traini
 ng habitats that also solve for adaptation to climate biodevastation on Ea
 rth. \n\nThe talk will focus on some of the various ways in which Free/Lib
 re Open Source technologies are incorporated into the project - with a str
 ong focus on the development of decentralized and distributed coordination
  systems for autonomous and collective action - and how creative technolog
 ists can plug in and participate in the project. \n\nAs a special show-and

DESCRIPTION:**39C3 LED badge -- SMD for Beginners**  \n\nThe 39C3 LED badge
  contains 42 LEDs that blink under control of of a pre-programmed 4 cent m
 icrocontroller. When the badge is alone\, the LEDs will blink randomly. Wh
 en it is among friends (when there are other badges nearby)\, it will disp
 lay a chaser pattern. \n\nIn this workshop you will learn how to solder Su
 rface Mounted Devices using a normal soldering iron.\n\nSuitable for begin
 ners. Under 16s only with responsible adult supervision.\n### 39C3 LED bad
 ge -- SMD for Beginners\n\n![39C3 LED badge](https://usercontent.events.cc
 c.de/congress/2025/hub/usercontent/b/7dccaedbb7ec/39C3badge.png)\n\nSurfac
 e Mounted Devices (SMDs) are small compared to Through Hole (TH) electroni
 c components\, and have the reputation of being difficult to work with as 
 a hobyist: Difficult to see and handle\, when you sneeze\, you loose them 
 and you can not easily use them on 2.54mm raster prototyping boards.\n\nSM
 D components are designed to be used in a reflow soldering process where t
 iny dots of solder paste are applied to a Printed Circuit Board (PCB)\, af
 ter which the SMD components are "Picked and Placed" on the PCB\, after wh
 ich the whole PCB is heated to the melting point of the solder ("reflowing
 ")\, actually completing the  electrical connections.\n\nThis workshop is 
 aimed at showing you that the reputation of being difficult to work with i
 s a bit undeserved\, and that you can also work with SMDs using just a  re
 gular soldering iron: With some simple tricks and a suitable selection of 
 components (not the smallest possible)\, the vast majority of people can s
 uccessfully complete this project.\n\nBeing able to solder SMD projects us
 ing just a simple soldering iron will also help you develop some skills th
 at are useful if you  need to do "rework" on reflow soldering projects. Re
 flow soldering is also not difficult to do as a hobbyist\, but requires a 
 few more tools like a stencil to apply solder paste and either an oven or 
 a hot plate to do the reflowing. It is\, however\, much quicker than solde
 ring the parts one by one\, and can yield more professional looking\, clea
 ner\, solder joints.\n\nThe project is an electronic name-badge - You shou
 ld write your name (or nick) on it and wear it. It contains 42 LEDs\, a mi
 crocontroller\, some support components and an InfraRed transmitter and re
 ceiver that allow it to communicate with other badges. When the badge dete
 cts the presence of other badges ("friends") nearby\, it will change its b
 ehaviour. It will not only interact with other 39C3 LED badges\, but also 
 with TBD badges - come visit the TBD assembly at komona or https://tbd.cam
 p\n\n![TBD badge](https://usercontent.events.ccc.de/congress/2025/hub/user
 content/e/d619de5f1be1/tbdbadge.png)\n\n### Costs\nThis workshop is donati
 on based. Materials costs are 2 euro per badge. Donations will go towards 
 1) covering costs of the badges\, 2) covering costs of running the hardwar
 e hacking area in general\, 3) covering costs of organizing TBD (see the T
 BD assembly at komona or https://tbd.camp)\n\n### Registration\nThe number
  of participants per session is limited. First come\, first served. Either
  get a participation voucher beforehand or show up early (there may be pla
 ces left).\nThere will be *numbered* paper vouchers available for each ses
 sion some time in advance of each session. If you get a voucher and do not
  show up *before* the designated starting time\, someone else may take you
 r spot. Please don't take multiple vouchers and don't take  vouchers if yo
 u don't actually plan to participate.\n\n### Getting a kit\nKits are part 
 of the workshop and not for sale separately. You can\, however easily sour
 ce your own PCBs and parts and make kits yourself because the design is  M
 IT licensed open source.\n\n### Links\nUnder construction: https://hackwin

DESCRIPTION:How can we predict soil moisture by measuring cosmic ray produc
 ts and what have trains to do with it? Ever wondered how this Dürremonitor
  works\, that you heared about in ther german news? These question and som
 e more I will try to answer while I give an overview of some of the resear
 ch that is done by the Helmholtz Centre for Environmental Research (UFZ).\
 nThe Dürremonitor is a programme that is often mentioned in the German new
 s when some regions experience drought. Alongside the Dürremonitor and the
  underlying Mesoscale Hydrological Model (MHM)\, there is ongoing research
  at the UFZ concerning soil moisture. Some of these studies involve measur
 ing soil moisture using a technique called cosmic ray neutron sensing (CRN
 S). Rather than taking measurements\, the MHM uses a physics-based model i
 ncorporating precipitation forecasts to predict drought or flood. These tw
 o strategies for quantifying soil moisture are therefore in opposition: th
 e measurement-based approach (CRNS) and the modelling-based approach (MHM/
 Dürremonitor). CRNS is a relatively new method of measuring soil moisture 
 based on the proportion of neutrons reflected by the soil (the principles 
 were discovered in the 1980s\, but it has only recently become commerciall
 y applicable). This method has several advantages over previous soil moist
 ure measurement methods: it is non-invasive\, easy to set up\, portable an
 d can therefore be used on trains.\n\nIn the talk I will give an overview 
 of the Dürremonitor and MHM and then focus on CRNS. I will explain the phy
 sical principles behind the method\, how it is implemented in practice by 
 making serveys using trains.\n

DESCRIPTION:Cardiac Implantable Electronic Devices (CIED)\, such as cardiac
  pacemakers and defibrillators\, are a fairly niche target for security re
 searchers\, in part due to a lack of manufacturer cooperation and device a
 ccessibility. This talk aims to provide insights into the challenges in de
 vice development and methods with which to research device security. Data 
 accessibility to patients will be touched upon.\nCIEDs may adversely affec
 t patients implanted with such devices should their security be compromise
 d. Although some efforts to secure these devices can be noted\, it has qui
 te often been lacking and may thus enable patient harm or data confidentia
 lity compromise by malicious actors. Given the vast consequences of securi
 ty vulnerabilities within this industry\, the author aims to provide insig
 ht into the challenges associated with designing security architectures fo
 r such platforms\, as well as possible methodology of researching these de
 vices safely even when lacking manufacturer cooperation and access to devi
 ce programmers.\n\nData collected by CIEDs and transmitted through remote 
 monitoring is an additional concern for patients. Whilst research has show
 n that most manufacturers do respond in a timely and comprehensive fashion
  to GDPR requests\, immediate data access is not yet possible and requires
  the patient to reach out to their doctors to obtain the requisite (event)
  data. A proposed solution is presented on how a patient communicator may 
 be designed to allow patients interested in their autonomy to perform limi
 ted device interrogation in a safe and secure manner.\n

DESCRIPTION:After we announced our results\, CTFs like Splunk's Boss of the
  SOC (BOTS) started prohibiting AI agents. For science & profit\, we keep 
 doing it anyways. In BOTS\, the AIs solve most of it in under 10 minutes i
 nstead of taking the full day. Our recipe was surprisingly simple: Teach A
 I agents to self-plan their investigation steps\, adapt their plans to new
  information\, work with the SIEM DB\, and reason about log dumps. No exot
 ic models\, no massive lab budgets - just publicly available LLMs mixed wi
 th a bit of science and perseverance. We'll walk through how that works\, 
 including videos of the many ways AI trips itself up that marketers would 
 rather hide\, and how to do it at home with free and open-source tools.\n\
 nCTF organizers can't detect this - the arms race is probably over before 
 it really began. But the real question isn't "can we cheat at CTFs?" It's 
 what happens when investigations evolve from analysts-who-investigate to a
 nalysts-who-manage-AI-investigators. We'll show you what that transition a
 lready looks like today and peek into some uncomfortable questions about w
 hat comes next.\nTHE PLAN\n\nLive demonstrations of AI agents speed-runnin
 g blue team challenges\, including the failure modes that break investigat
 ions. We'll show both what happens when we try the trivial approaches like
  “just have claude do it”\, “AI workflows”\, and what ultimately worked\, 
 like managed self-planning\, semantic SIEM layers\, and log agents. Most c
 an be done with free and open tools and techniques on the cheap\, so we wi
 ll walk through that as well.\n\nTHE DEEP DIVE\n\n* Why normal prompts and
  static AI workflows fail\n* Self-planning investigation agents that evolv
 e task lists dynamically\n* What we mean by semantic layers for calling da
 tabases and APIs\n* How to handle millions of log events without bankrupti
 ng yourself\n* Why "no AI" rules are misguided technically and conceptuall
 y\n\nGOING BEYOND CTFS\n\nThe same patterns that trivialize training exerc
 ises work on real SOC investigations. We're watching blue team work fundam
 entally transform - from humans investigating to humans managing AI invest
 igators. Training programs teaching skills AI already automates. Hiring pr
 actices that can't verify who's doing the work. Certifications losing mean
 ing. More fundamentally\, when we talk about who watches the watchers\, a 
 lot is about to shift again.\n

 p**\n\nIn 1965\, something new happened: Artworks were on public display t
 hat were created with the help of a computer. These exhibitions of  Georg 
 Nees\, A. Michael Noll with Béla Julesz and Frieder Nake with Georg Nees t
 ook place in Stuttgart and New York.\n\nWe looked into different technique
 s of algorithmic drawing. From hommages to our own ideas\, we created seve
 ral works – sixty years after the first exhibitions.\n\nYou can find some 
 of these works on the walls of the CCH. Additionally\, we want to give sev
 eral interactive workshops. Here\, you can experiment on your own drawings
  and take them home.\n\nTimes:\n* DAY 1: 15:00 - 16:30\n* DAY 2: 15:30 - 1

DESCRIPTION:Most people and organizations have their very own way of acquir
 ing\, organizing\, archiving\, sharing\, and collaborating on knowledge re
 positories. A broad spectrum of opinions and approaches resulted in a dive
 rse and rich ecosystem of knowledge management solutions. Nevertheless\, t
 his also implies scattered and disconnected knowledge sources. What would 
 it mean to build bridges among wikis and federate knowledge?\nThis worksho
 p is going to be heavily centred on a twofold discussion\, exploring the c
 hallenge of federated knowledge starting from two questions.\n\n- What doe
 s it mean to *federate* knowledge repositories?\n- Instead of pursuing a s
 ilver-bullet solution to embrace all use-cases\, what would it mean to fos
 ter and enable interoperability for different software?\n\nThese questions
  stem from years of questioning and wondering how to integrate my personal
  note-taking and collective\, participatory knowledge management at work\,
  in organizations\, institutions\, and informal collectives. Recently\, I 
 began actively researching this topic as I started playing with the [Media
 Wiki API](https://www.mediawiki.org/wiki/API) to cross-synchronize my loca
 l Markdown notes and the [XPUB wiki](https://pzwiki.wdka.nl/mediadesign/)\
 , the public learning wiki of the [Experimental Publishing](https://xpub.n
 l) master. I am puzzled by taking advantage of the potential of a specific
  software (in this case\, MediaWiki) while fearing of being locked-in.\n\n
 Some further\, more specific\, insights and questions:\n\n- Local-first ap
 proaches and software (e.g. [Reflection](https://github.com/p2panda/reflec
 tion))\n- Interesting experiments based on existing protocols\, such as [I
 bis](https://ibis.wiki)\n- What do we take of semi-open and obscure yet ve
 ry cool initiatives like [Anytype](https://anytype.io)\n- The power and th
 e limits of plain-text: how to enable collaboration on simple Markdown fil
 es and build on top of it\, as [Obsidian](https://obsidian.md) does\n

  to have tools that worked better. Every forum built on free forum softwar

DESCRIPTION:*What are atoms doing in space anyways?* This talk will provide
  a brief overview of applications of quantum technologies in space ranging
  from precise timing and inertial measurements to fundamental physics.\nQu
 antum technologies have seen a wide field of applications in medicine\, ge
 osciences\, computing and communications\, in many cases bridging the gap 
 from laboratory experiments to commercial products in the last decade. For
  terrestrial applications that is. But what about going to space?\n\nQuant
 um physics based sensors and experiments promise higher accuracy\, sensiti
 vity or better long term stability as they rely on immutable properties of
  atoms. When properly manipulated\, these (ultra-)cold atoms are likely to
  outperform state of the art instruments. Experiments conducted on soundin
 g rockets demonstrated important steps like Bose-Einstein Condensate creat
 ion during a few minutes in microgravity\, enabling more advanced quantum 
 experiments in the future.  The International Space Station and the Tiango
 ng Space Station host dedicated experiments like ultrastable clocks as wel
 l as flexible research infrastructure for fundamental research benefitting
  from long free-fall times. However\, the deployment of such technologies 
 on satellites is not as advanced. Satellite missions utilizing quantum sen
 sors or performing long term experiments are subject to studies and propos
 als backed by a broad scientific community aiming at better understanding 
 of climate change\, interplanetary navigation or tests of general relativi
 ty. First steps towards realization of such missions are taken by ESA\, NA
 SA and various national space agencies as well as universities funded by n
 ational agencies or the EU.\n\nThis talk will detect the current state of 
 atoms in space and give an overview of active programs to deploy quantum s
 ensors on operational satellite missions. The focus is on future applicati
 ons in geosciences and related fields employing the same technology.\n

DESCRIPTION:Abbreviations such as WSIS+20\, IGF\, IETF\, DIEM\, ICANN\, PDP
 \, ITU or W3C regularly appear in discussions about the Internet\, yet oft
 en remain vague. This talk provides an update on the current state of Inte
 rnet governance and explains why decisions made in United Nations processe
 s have direct implications for technical standards\, digital infrastructur
 e\, and power asymmetries.\nThe starting point is the UN’s WSIS+20 review 
 process\, which negotiated the future of the Internet Governance Forum and
  the roles of stakeholders within it. Against this backdrop\, the talk tra
 ces the origins of the so-called multistakeholder approach and examines ho
 w it works in practice and where its limits lie.\n\nWhat role do technical
  standardization organizations such as the IETF\, ICANN\, ITU or the W3C p
 lay in an increasingly geopolitical environment? Who sets the rules\, who 
 defines the standards\, and who is left out of these processes?\n\nThe aim
  of the talk is to make the connections between technology and internation
 al politics visible and to explain why Internet governance matters to ever
 yone interested in an open\, global\, and interoperable Internet.\n

DESCRIPTION:Kennt ihr schon unser Kinder und Jugendbuch "Ada & Zangemann"\n
 In einer riesigen Villa hoch oben über der Stadt lebt der berühmte Erfinde
 r Zangemann. Erwachsene wie Kinder lieben seine Erfindungen und\nwollen si
 e unbedingt haben. Doch dann geschieht etwas: Zangemann kommt in die Stadt
 \, um seine Erfindungen wieder einmal aus der Nähe zu\nbetrachten und – RU
 MMS! – ein Kind fährt ihm mit seinem Skateboard gegen das Schienbein. Wute
 ntbrannt trifft der Erfinder eine Entscheidung und dann passieren merkwürd
 ige Dinge ... Aber das kluge Mädchen Ada durchschaut\, was vor sich geht. 
 Gemeinsam mit ihren Freund:innen schmiedet sie einen Plan.\n\nGerne würden
  wir dieses Buch mit euch\, mit Kindern und Jugendlichen lesen. Im Anschlu
 ss daran wollen wir gemeinsam Postkarten und Briefe an\nAda und oder Zange
 mann verfassen. In diesen wollen wir den Kindern und Jugendlichen die Mögl
 ichkeit geben zu reflektieren\, warum technische\nKontrolle wichtig ist un
 d wie diese aussehen kann.\n

DESCRIPTION:This workshop aims to equip techies and activists with some und
 erstanding to recognize and address emotional concerns in the context of d
 igital rights. Together\, let’s cultivate a flourishing community that pri
 oritizes well-being and empowerment in the face of technology-driven chall
 enges.\nJoin us for an engaging and transformative workshop designed speci
 fically for techies and digital rights activists. In an era increasingly d
 efined by surveillance and technological risks\, it's essential to address
  the emotional toll these challenges take on our community and beyond.\n\n
 During this interactive session\, participants will:\n\nReflect Together: 
 Engage in a moment of introspection and heartfelt group discussions about 
 the emotions surrounding surveillance\, technology\, and associated risks.
  Learn to actively listen and share your experiences in a supportive envir
 onment where your feelings are validated.\n\nBrainstorm Solutions: Explore
  ways our communities can provide more support to their members and be gen
 erous towards a broader audience\, particularly those unfamiliar with digi
 tal rights issues. Learn how to communicate effectively about these feelin
 gs and provide alternatives and resources for those feeling overwhelmed.\n
 \nExperience Safe Spaces: Throughout the workshop\, we will create an emot
 ionally safe space that allows participants to experience firsthand what a
  supportive environment feels like. This is not just a theoretical exercis
 e\, but a practice in fostering community resilience and mutual care.\n\nA
 dditionally\, participants will receive comprehensive material to help the
 m easily reproduce this workshop in their own communities. With these tool
 s\, you'll be empowered to extend the conversation and emotional support t
 o others who share similar feelings about the challenges posed by technolo
 gy.\n

DESCRIPTION:Renowned for vibrant sets and relentless crate-digging\, she ca
 rries the spirits of the city’s underground.\nWhere dancefloor rush meets 
 quiet mind\, she is pretty much into early-2000s minimal\, rare electro\, 
 house-infused old-school Goa and well deserved bleeps and bloops.\nSound h
 as been a lifelong passion\, but my deep love for dancefloor-related elect
 ronic music truly ignited through attending raves in my hometown. I immers
 ed myself in arts\, including studies in systematic musicology\, event tec
 hniques and audio engineering\, while working at Remoto-Records and consta
 nly organizing events with my collective Phantasia at various locations\, 
 creating unique spaces for musical exploration\, aswell as the launch of o
 ur own label\, where you can also find my very first release on wax.\nI al
 so perform under my artist alias problem.child\, where I focus on CD-only 
 sets featuring 90s and early 2000s Goa and progressive-house.\nAdditionall
 y\, I hold a bi-monthly residency for my show Exo-Drive on London-based ra
 dio station Komrad 94\n

DESCRIPTION:Computer programs run with all privileges of the running user. 
 If your user can read your emails\, then so can any other program you run.
  However\, many programs do not need most permissions and perhaps should n
 ot have them at all.\n\nThis workshop demonstrates quite simple ways in wh
 ich software can self-restrict itself. The focus will not be on foreign\, 
 potentially malicious software\, but on hardening programs against miscond
 uct and future security vulnerabilities.\n\nSeveral operating systems have
  developed different interfaces that restrict software beyond its normal s
 cope. This workshop will focus on POSIX and especially OpenBSD because of 
 its user-friendly APIs. Although other operating systems\, such as Linux\,
  will be discussed\, they will not be covered in depth due to their more c
 omplicated APIs.\n\nWithin the workshop part\, software with known securit
 y vulnerabilities is then patched together - usually with almost a single 
 line. Ideally\, an exploit has hardly any effect afterwards\, although the
  vulnerability is still present. This is not intended to encourage careles
 sness\, but rather to demonstrate the development of a further safety net 
 for software.\n\nA basic understanding of programming is required and\, mo
 re importantly\, an interest in the topic. You will need to bring an SSH c
 lient\, for example a laptop with (almost) any operating system.\n\nThe la
 nguage will be either English or German\, depending on who shows up.\n

DESCRIPTION:Can organisations with limited resources be digitally sovereign
  and still provide modern services? It is not trivial\, but the FSFE prove
 s it's possible. In this workshop we want to share our story and hear from
  you how you are running your NGO on FreeSoftware.\nSince its founding mor
 e than 20 years ago\, the FSFE has been pursuing this way. Right from the 
 start\, we have relied on Free Software although it sometimes meant not be
 ing able to use and offer trendy services. Also\, given the limited resour
 ces\, we constantly have to choose between useful features and maintainabi
 lity.\n\nAnd still\, neither is our infrastructure perfect nor is it 1:1 t
 ransferable to other organisations. But we think it's important that organ
 isations exchange their experiences and learning\, especially when it's ab
 out something as important as software freedom.\n\nYou can find a deep div
 e of the FSFE IT infrastructure in [our news article from 2021](https://fs

DESCRIPTION:\n## Session Description\n\nWe constantly build\, use\, maintai
 n\, and adapt physical and digital tools and infrastructures — both inside
  and outside formal institutions\, and far beyond classical environmental 
 citizen science.\n\nThis session invites participants involved in **commun
 ity projects** to share concrete **user stories** about how they actually 
 work:\n- what they try to do\,\n- what doesn’t work\,\n- what they avoid u
 sing\,\n- what they need\,\n- and why.\n\nRather than presenting solutions
  or pitching an infrastructure\, the session focuses on:\n\n### Session Fo
 cus\n- **Lived practices and workflows**\n- **Shared experiences and bottl
 enecks** in maintaining infrastructure\n- **Research activities within com
 munities**\, including success stories\n- **Trust issues and refusals** re
 lated to infrastructure services\n- **Boundaries around data\, governance\
 , and centralisation**\, with concrete project examples\n\n### Method\nPar
 ticipants will fill in short **user stories based on real situations**.  \
 nThese stories will be **anonymised** and analysed to identify patterns th
 at can inform the **early design of a future research infrastructure (RIEC
 S)** — before assumptions harden into technical or governance choices.\n\n

DESCRIPTION:\nSelf-replicating programs spontaneously emerge from randomly 
 initialized code in simple programming languages like Brainfuck\, Forth\, 
 and assembly\, without any designed replication mechanisms or fitness func
 tions. Through self-modification and random interactions alone\, these sys
 tems transition from "pre-life" chaos to "life" dynamics where replicators
  compete\, evolve\, and develop increasingly complex behaviors\, offering 
 new insights into how life itself might originate on any computational sub
 strate.\n

DESCRIPTION:\nNachdem die ursprünglich für 14:30 an Tag 3 geplante Session 
 dem migrantischen Widerstand umgewidmet wurde\, hier nochmal ein neuer Ter
 min.\n***\n\nDiese Session wird sich aus den Erfahrungen und Begegnungen d
 er bisherigen 39c3 ChaosTage speisen. Und wird den Versuch unternehmen\, e
 inige begonnene Überlegungen gemeinsam mit euch fortzuführen. Mehr Gespräc
 h als Vortrag. Mehr gemeinsame Suchbewegungen vollführen\, als für alles A
 ntworten zu erwarten.\n\nWir werden um folgende Themen kreisen\, streifen 
 und streicheln:\n\n+ Präfiguration\, ja gerne\, aber wie? Wer mit wem? Und
  wozu?\n+ Konflikte gehören zum Leben dazu\, bei der Aushandlung von Bedür
 fnissen\, und darüberhinaus\, das ist nicht immer Friede\, Freude\, Eierku
 chen\, aber mit ein bischen üben und Bewusstseinskultur wird das was mit d
 em konstruktiv Streiten und Konflikte positiv transformieren\n+ Ist Anarch
 ismus als Begriff heute noch brauchbar? Praktisch\, nicht theoretisch.\n+ 
 Wie bekommen wir es hin\, dass beim Antifaschismus alle zusammen gegen den
  Faschismus arbeiten? [#widersetzen](https://events.ccc.de/congress/2025/h
 ub/tag/widersetzen)\, und intersektional(er) darüberhinaus.\n+ Oder wenn w
 ir es anders nennen\, unser gemeinsames Ziel dabei nicht verloren geht: ei
 ne für alle Lebewesen friedvolle\, liebevolle\, achtsame\, freudvolle Welt
  in der die wechselseitigen Bedürfnisse uns die Orientierung für unser Han
 deln geben (so zumindest 1 Serviervorschlag von mir) und die Möglichkeiten
  und Ressourcen im Blick bleiben\, wie wir das (um-)verteilen was es gibt\
 , und die Verteidigung gegenüber denjenigen\, die das nicht wollen und uns
  weiter angreifen werden.\n+ Welche Kompetenzen und Reflexionsfähigkeiten 
 fehlen uns aktuell noch\, um belastbare intersektional orientierte (Kampf-
 )Bündnisse zu schmieden und aufrechtzuerhalten?\n+ Und wofür das Ganze? (n
 ochmal ein Ausblick Richtung Utopie? We will see...\n\nFreue mich auf beka
 nnte und neue Gesichter und Körper.\n\nLassen wir es glitzern und knallen\
 , mit viel Alerta\, alles Allen und bunten Einhörnern.\n

DESCRIPTION:„Hattest du einen schönen Congress?“ „Ja klar\, also…ähm…was er
 zähle ich jetzt?“\nDer Congress ist intensiv. Er inspiriert\, überfordert\
 , überrascht und berührt. Gemeinsam extrahieren wir unsortierte Congress-E
 rlebnisse aus dem Cache und booten neu.\nGar nicht so einfach\, in Worte z
 u fassen\, was zwischen LEDs und Gesprächen\, Vorträgen und Hallen\, Works
 hops und Zufallsmomenten entsteht. in diesem Workshop erproben wir Methode
 n des kreativen und ethnographischen Schreibens. Wir schreiben für uns all
 ein und kollaborativ\, ausgehend vom Congress\, über uns und diese Welt.\n
 \nSchreiben kann mehr sein als eine Technologie\, um sensorische Signale z
 u speichern. Schreibend lässt sich reflektieren und die Welt gestalten. Sc
 hreiben ist in diesem Sinne eine politische Praxis. Die Geschichten\, die 
 wir über die Welt erzählen und uns darin erzählen\, prägen\, was wir für m
 öglich halten. Kultur\, Wissen\, Weltordnungen werden von Menschen geschri
 eben\, gelesen und weitergetragen. Wenn wir selbst zu Schreibenden werden\
 , können wir diese Geschichten anders erzählen\, verschieben und aufbreche
 n. Hier knüpfen wir an „speculative fabulations“ (Donna Haraway) an: die I
 dee\, neue Zukünfte zu erfinden\, indem wir anders erzählen.\nWir begreife
 n ethnografisches Schreiben als eine Praxis des „reflecting selves and oth
 ers“: eine Form\, die uns erlaubt wahrzunehmen\, wie wir selbst und andere
  in Beziehung stehen\, sich bewegen\, fühlen\, handeln.\n\nMit praktischen
  Übungen\, kleinen Inputs und gemeinsamen Diskussionen probieren wir versc
 hiedene Zugänge aus: vom freien Schreiben über Vignetten bis hin zu kollab
 orativen Texten\, die aus unseren Congress-Erlebnissen heraus entstehen.\n
 \nVorkenntnisse sind nicht erforderlich\, aber willkommen. Bringt euch ang
 enehmes Schreibzeug mit: Laptop\, Telefon oder Papier und Stift. Zusätzlic
 h haben wir auch Papier und Stifte da.\n

DESCRIPTION:Ich möchte mit euch das Netzwerk erkunden\, vom Endgerät bis zu
 m Router\, der das Internet "anruft". Wir werden uns auf das lokale Netzwe
 rk beschränken und zum Schluss einmal durch spielen was im Netzwerk auf de
 r Leitung eigentlich passiert.\nDu hast keine oder kaum Ahnung von IT-Netz
 werktechnik und wolltest immer schon mal wissen\, was da eigentlich passie
 rt? Was läuft zwischen Router/Fritzbox und unserem Endgerät ab\, damit wir
  im Internet surfen können? Wenn dich das interessiert\, dann ist dieser W
 orkshop vielleicht was für dich. Denn es soll darum gehen\, wie die Basics
  der Netzwerk-Technik funktionieren. Dabei werden wir in Gruppen die Regel
 n in einem Netzwerk erkunden und zwar Schicht für Schicht. Als Leitfaden o
 rientieren wir uns am OSI-Model\, das Modell der Netzwerktechnik\, an das 
 sich keiner hält. Es wird um MAC-Adressen\, IP-Adressen\, Ports\, UDP und 
 TCP gehen. Weil alle Theorie irgendwie staubig ist\, geht es in diesem Wor
 kshop einen Schritt weiter. Die erkundeten Regeln werden in einem Netzwerk
 spiel ganz praktisch umgesetzt\, in dem wir Netzwerkwitze durch ein Netzwe
 rk  schicken. Dafür brauchen wir imaginäre Brieftauben nach RFC 1149 und 6
 214 (bitte keine realen Flugtiere und Fluggeräte mitbringen - Danke) und e
 inige imaginäre Hardware.\n\nBitte Humor\, Fantasie und Laptop mit RJ45-An
 schluss(LAN/Ethernet-Kabel) zur Recherche mitbringen (Teilnahme ohne Hardw
 are ist auch möglich). Die Ergebnisse sollen am Ende allen Workshop-Teilne

DESCRIPTION:This workshop is to establish a longer term working group that 
 will threat model and abusability test (different from abuse test) common 
 open source governance and community frameworks. The primary focus of this
  session is for Phase 1 preparation: communications norms around this proj
 ect.\nRecent years have seen an increase in stress and pressure resulting 
 from both actor and non-actor harms due to the pivot in how we manage our 
 OSS communities in digital spaces. To better equip the broader OSS communi
 ty with how to document\, detect\, and handle these issues we need to thre
 at model and abusability test common governance and community frameworks a
 nd publish relevant guidance.\n\nIn this session\, we are starting with Ph
 ase 1: building communication norms. This is because the work that follows
  carries inherent risk as we identify\, research\, and model these framewo
 rks. We'll also publish our recommended communications practices regarding
  sensitive information in open source.\n\nGithub: [https://github.com/nive

DESCRIPTION:\nHallo\, ich muss euch leider mitteilen\, dass ich den Worksho
 p absagen muss\, da ich mir eine Erkältung eingefangen habe\, und wenig St
 imme und Energie habe und das gerade über meine Kapazitäten geht. Tut mir 
 sehr Leid\, hätte das gerne mit euch gemacht\n\nFür diejenigen die trotzde

 nerarbeit im Chaos: https://signal.group/#CjQKILTHwUeZ6z5tjh2aFLFUJqDUBZdc
 4RM6pQrtinvOgCnJEhB6V3OHw1wAe73YgRwRbCKG\n\nDies ist der Folgeworkshop zum
  vorherigen Männerkreis. Wir glauben dass es wichtig ist\, dass wir Männer
  explizit von FLINTA* lernen\, daher all creatures welcome.\n\nIn dem Work
 shop wollen wir uns zu folgenden Fragen ins Gespräch kommen:\n\n- Welche E
 rfahrungen haben wir mit Männerarbeit?\n- Wie holen wir uns (auch außerhal
 b der Bubble) ab?\n- Wie schaffen wir es den Bruch zu unseren Schwestern* 
 anzuerkennen und auszuhalten ohne uns dabei zu entmündigen und zu verachte
 n\n- Wie schaffen wir es unsere Schutzwalle soweit unten zu lassen\, damit
  wir lernen können\, aber trotzdem liebevoll und sorgsam mit uns umzugehen
 ?\n- Wie können wir uns trotz unseres internalisiertem Leistungsanspruchs 
 erlauben uns klein\, bedürftig und unsicher zu zeigen?\n\nIch bin Timon (e
 r) von menbracing. Wir sind eine kleine Initiative von Männern die sich in
 spiriert von der Arbeit von Bell Hooks\, Adrienne Maree Brown\, Veit Linda
 u und Anderen an männlicher Care-Arbeit versuchen.\n

DESCRIPTION:\nIn dieser Session zeigen wir\, wie Ihr in weniger als 20 Minu
 ten und Kosten für Hardware von weniger als 30 Euro einen Werbefilter baue
 n könnt. \nVorkenntnisse: keine außer allgemeine Neugier\nHardwareanforder
 ungen: keine (für die Live Demo)\, falls Ihr mitmachen möchtet irgend ein 
 Microcomputer mit RasPiOs oder Debian und SSH\n\nHintergrund: bei vielen E
 ndgeräten bzw. Softwareprodukten ist es immer schwerer\, Werbung und Track
 ing herauszufiltern (insbesondere bei Smartphones).  Dort sind die Plugins
  wie UBlock Origin entweder nicht verfügbar oder sie gelten nur für den Br
 owser und nicht für die Apps. Die Lösung ist\, auf dem Weg in das Internet
  einfach eine Sperrliste zu haben\, die alle Verbindungen zu Werbeanbieter
 n blockt. Eine gängige OpenSource Lösung ist PiHole. Es braucht nur minima
 le Hardware. Ein Raspberry Pi für weniger als 30 Euro reicht dafür aus ode
 r ein alter Computer\, der sonst keine Aufgabe mehr hat. In der Session ze
 igen wir wie einfach es ist\, ein PiHole aufzusetzen und in das Heimnetzwe
 rk einzubinden.  Seid gespannt auf das neue Nutzungserlebnis eines Interne
 ts (fast) ohne Werbung. Wir stellen eine Linkliste zur Verfügung. Damit kö
 nnt Ihr das Gezeigte zu Hause "nachbauen" könnt: http://ohok.org/pi-hole-l

 are used to make modern electronic devices. We will cheat the same way the
  electronics industry does\, and learn the techniques of stencil paste pri
 nting and reflow soldering. You will learn a technique that stops your han
 ds from shaking\, so you can very very precisely place microscopic parts. 
 We will make an electronic cat that purrs if you handle it correctly. No p
 rior experience or knowledge of anything electronic needed. Caffeine use i
 s not recommended immediately before. All tools are provided.  Takes aroun
 d 2 hours.\n\n**Materials costs**:  \n20€ if you want to make a board\, fr

 com/cfe/projects.php#brainmachine)** that is preprogrammed with a really n
 ice meditation sequence. As well as a device that can help you relax and m
 editate\, a nice bonus is that everyone hallucinates beautiful colors and 
 patterns along the way.\n\nThe Brain Machine is totally [open hardware](ht
 tps://github.com/maltman23/Brain_Machine_kit)\, and created to be hackable
 \, so you can re-program it with any computer\, with software that is free
  to download and use.\n\nThis workshop is for **total beginners** to learn
  to solder.\n\nFor ages 10 - 100.\n\n**Materials costs**:  \nThe workshop 
 is free\, but if you would like to partake in the hands-on aspects of the 
 workshop\, Mitch will have Brain Machine kits for **€25**.\n\n**Taught by*
 * [Mitch Altman](http://en.wikipedia.org/wiki/Mitch_Altman).\n\n_**Optiona
 l**:  Bring your laptop if you want to go home with the free Arduino softw
 are installed on it.  \nArduino software runs on Windows\, MacOS and Linux
 ._\n\n_**IMPORTANT NOTE:** The Brain Machine uses blinking lights\, and is
  not recommended for people who are photosensitive._\n\n**Workshop Itinera
 ry**:\n* Intro to Sound & Light Machines\n* Learn to solder. Don't let thi
 s scare you! I've taught tens of thousands of people to solder\, most of w
 hom have never made anything before in their lives. It is actually a very 
 easy skill to learn. It is also very useful.\n* How to re-program your Bra
 in Machine for creating other brainwave sequences\n\n**Registration**:  \n
 Buy a kit at the Hardware Hacking Area to guarantee a seat\, or come by ea
 rly! (And please do arrive early\, regardless!) First come\, first served.

DESCRIPTION:\nSince a couple of years\, I've been using a custom mouse curs

 \, and people are amused that there's a turtle on my screen! :D\n\nIn this
  workshop\, I'll explain how cursor themes work on Linux\, and teach you h
 ow to generate your own one! It could be anything you want – some ideas:\n
 \n- Draw your own arrows (cool-looking? Weird ones?)\n- Repurpose your fav
 orite icons/logos (so that everyone immediately knows that you're using Ar
 ch btw)\n- Blåhajs?!\n- High-contrast cursors that are actually more acces
 sible to you\n\nBring a Linux laptop! And it'd be ideal if you could alrea
 dy install the vector graphics program Inkscape and the command line tool 
 `xcursorgen`! I'll show you a little script that will help you generate th
 e theme. If you feel comfortable with another graphics program\, you can a
 lso use that instead of Inkscape.\n\nThe resulting themes work both on X.O
 rg as well as Wayland.\n
