All Sorted by Machines of Loving Grace? "AI", Cybernetics, and Fascism and how to Intervene (en)

Katika Kühnreich

While the extreme right is on the rise in many countries and climate change is unrolling, a promising future seems to be written: According 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”. But what kind of future is the one that is promised? And what is the connection between power cycles of tech company owners and people who's believes 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 their heads. This 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 take a look in the future the “tech bros” want to lure us in. This 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 where we will be sorted by machines. And, in taking a look on past movements opposing authoritarianism and will examine mindsets and possibilities of resistance as well as the possibility of restarting everything. Because we have a planet and loved ones to lose. Wear your safety cat-ears, buckle up, it will be a wild, but entertaining ride.
Building hardware - easier than ever - harder than it should be (en)

Kliment

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 enshittification and vibe coding. And yet, while removing technical and financial 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 practitioners, for no good reason at all. I've been teaching advanced electronics manufacturing skills to absolute beginners for a decade now, and they've 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 think they can't should try.
Liberating Bluetooth on the ESP32 (en)

Antonio Vázquez Blanco (Antón)

Despite how widely used the ESP32 is, its Bluetooth stack remains 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.
Chatkontrolle - Ctrl+Alt+Delete (de)

khaleesi, Markus Reuter

Seit jetzt schon vier Jahren droht aus der EU die Chatkontrolle. In Deutschland ist das Thema nach den Protesten im Oktober aktueller denn je - und sogar Jens Spahn und Rainer Wendt sind plötzlich gegen diese Form der Überwachung. In diesem Vortrag schauen wir zurück und erklären was, vor allem im Hintergrund, passiert ist. Wir nehmen die Position der Bundesregierung genau unter die Lupe und werfen einen Blick auf die Schritte, die auf EU-Ebene vor uns liegen.
Hacking washing machines (en)

Severin von Wnuck-Lipinski, Hajo Noerenberg

Almost everyone has a household appliance at home, whether it's a washing machine, dishwasher, or dryer. Despite their ubiquity, little is publicly documented about how these devices actually work or how their internal components communicate. This talk takes a closer look at proprietary bus systems, hidden diagnostic interfaces, and approaches to cloud-less integration of appliances from two well-known manufacturers into modern home automation systems.
A post-American, enshittification-resistant internet (en)

Cory Doctorow

Trump has staged an unscheduled, midair rapid disassembly of the global system of trade. Ironically, it is this system that prevented all of America's trading partners from disenshittifying their internet: the US trade representative threatened the world with tariffs unless they passed laws that criminalized reverse-engineering and modding. By banning "adversarial 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 enshittificatory predations of the ketamine-addled zuckermuskian tyrants of US Big Tech. Well, when life gives you SARS, you make sarsaparilla. The Trump tariffs are here, and it's time to pick the locks on the those handcuffs and set the world's hackers loose on Big Tech. Happy Liberation Day, everyone!
Chaospager - How to construct an Open Pager System for c3 (en)

Max, Julian

In this talk, we will give an introduction into the project (i.e. how it all started at 38c3 and why we are here now), provide an in-depth review of how the development process of our pager worked and what our future goals are. In 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 prototype, to a first working pager on a proper PCB). We will also present our plans of connecting our POCSAG transmitter infrastructure to THOT (CERTs own dispatch software). For our in-depth review about the project, we explain how we encountered major reception problems, how we analyzed them at easterhegg22 and conducted experiments there, and why we are opting for a custom HF frontend design instead of an already-made one from chinese vendors. Moreover, we provide an overview of our transmitter devices and give some advice on how to replicate those. Lastly, we will discuss further challenges and what our next goals are. If we are reaching our milestone until 39c3, we will also give a live demo of the system.
Cracking open what makes Apple's Low-Latency WiFi so fast (en)

Henri Jäger

This talk presents Apple's link-layer protocol Low-Latency WiFi and how it achieves its real-time capabilities to enable Continuity features like Sidecar Display and Continuity Camera. We make more kernel logging available on iOS and build a log aggregator that combines and aligns system- and network-level log sources from iOS and macOS.
In-house electronics manufacturing from scratch: How hard can it be? (en)

Augustin Bielefeld, Alexander Willer

Why is electronics manufacturing hard? Can it ever be made easy and more accessible? What will it take to relocate industrial production to Europe? We 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 out a lot of the difficulties are rarely talked about or hidden behind "manufacturing is high CAPEX". Come and learn with us the nitty gritty details 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.
Xous: A Pure-Rust Rethink of the Embedded Operating System (en)

bunnie, Sean "xobs" Cross

Xous is a message-passing microkernel implemented in pure Rust, targeting secure embedded applications. This talk covers three novel aspects of the OS: hardware MMU support (and why we had to make our own chip to get this feature), how and why we implemented the Rust standard library in Rust (instead of calling the C standard library, like most other Rust platforms), and how we combine the power of Rust semantics with virtual memory to create safe yet efficient asynchronous messaging primitives. We conclude with a short demo of the OS running on a new chip, the "Baochip-1x", which is an affordable, mostly-open RTL SoC built in 22nm TSMC, configured expressly for running Xous.

Gegenmacht - Best of Informationsfreiheit (de)

Arne Semsrott

Sind mehr Infos wirklich die Lösung? Ob Jens Spahn, Philipp Amthor oder Friedrich Merz - sie alle sagen offen, was sie vorhaben und machen keinen Hehl aus ihren Verbindungen zur Trump-Regierung, zu Milliardären und der fossilen Lobby. Was bringt Transparenz in Zeiten der autoritären Wende?
AI Agent, AI Spy (en)

Udbhav Tiwari, Meredith Whittaker

Agentic AI is the catch-all term for AI-enabled systems that propose to complete more or less complex tasks on their own, without stopping to ask permission or consent. What could go wrong? These systems are being integrated directly into operating systems and applications, like web browsers. This move represents a fundamental paradigm shift, transforming them from relatively neutral resource managers into an active, goal-oriented infrastructure ultimately controlled by the companies that develop these systems, not by users or application developers. Systems like Microsoft's "Recall," which create a comprehensive "photographic memory" of all user activity, are marketed as productivity enhancers, but they function as OS-level surveillance and create significant privacy vulnerabilities. In the case of Recall, we’re talking about a centralized, high-value target for attackers that poses an existential threat to the privacy guarantees of meticulously engineered applications like Signal. This shift also fundamentally undermines personal agency, replacing individual choice and discovery with automated, opaque recommendations that can obscure commercial interests and erode individual autonomy. This talk will review the immediate and serious danger that the rush to shove agents into our devices and digital lives poses to our fundamental right to privacy and our capacity for genuine personal agency. Drawing from Signal's analysis, it moves beyond outlining the problem to also present a "tourniquet" solution: looking at what we need to do *now* to ensure that privacy at the application layer isn’t eliminated, and what the hacker community can do to help. We will outline a path for ensuring developer agency, granular user control, radical transparency, and the role of adversarial research.
Blackbox Palantir (de)

Constanze Kurz, Franziska Görlitz

Asahi Linux - Porting Linux to Apple Silicon (en)

sven

In this talk, you will learn how Apple Silicon hardware differs from regular laptops or desktops. We'll cover how we reverse engineered the hardware without staring at disassembly but by using a thin hypervisor that traces all MMIO access and then wrote Linux drivers. We'll also talk about how upstreaming to the Linux kernel works and how we've significantly decreased our downstream patches in the past year. As an example, we will use support for the Type-C ports and go into details why these are so complex and required changes across multi subsystems. In the end, we'll briefly talk about M3/M4/M5 and what challenges we will have to overcome to get these supported.

Not an Impasse: Child Safety, Privacy, and Healing Together (en)

Kate Sim

From the EU’s “Chat Control” to the UK’s age verification, there is a growing legislative momentum across jurisdictions to regulate the Internet in the name of protecting children. The monstrosity of child sexual abuse looms large in shaping how policymakers, advocates, and the public understand the problem area of and propose solutions for detecting, reporting, and removing harmful/illegal content. Children’s safety and adults’ privacy are thus pitted against each other, deadlocked into an impasse. As technologists deeply concerned with safety and privacy, where do we go from here?
Handy weg bis zur Ausreise – Wie Cellebrite ins Ausländeramt kam (de)

Chris Köver

Seit Anfang 2024 dürfen Ausländerbehörden Smartphones von ausreisepflichtigen Menschen nicht nur durchsuchen, sondern gleich ganz behalten – „bis zur Ausreise“. Was als geringfügige Änderung im Aufenthaltsgesetz daherkommt, erweist sich als massiver Eingriff in Grundrechte: Menschen verlieren nicht nur die Kontrolle über ihre Daten, sondern auch ihr wichtigstes Kommunikationsmittel – auf unbestimmte Zeit. Hier hört ihr, welche absurden Blüten das treibt. Von Bayern bis NRW haben Bundesländer inzwischen eigene IT-forensische Tools für ihre Behörden angeschafft, um auf den Geräten nach “Indizien” für die Herkunft zu suchen. Sie setzen Methoden ein, wie wir sie sonst aus Ermittlungsverfahren oder von Geheimdiensten kennen – um die Geräte von Menschen zu durchsuchen, die nichts verbrochen haben.
And so it begins - Wie unser Rechtsstaat auf dem Highway Richtung Trumpismus rast – und warum afghanische Kläger*innen für uns die Notbremse ziehen (de)

Eva, Elaha

Wenn die Regierung sich nicht mehr an das eigene Recht gebunden fühlt, markiert das nicht nur einen politischen Spurwechsel, sondern die Auffahrt auf den Highway to Trumpism. Zeit die Notbremse zu ziehen! Normalerweise trifft es in solchen Situationen immer zuerst diejenigen, die sich am wenigsten wehren können. Doch was passiert, wenn genau diese Menschen mit juristischen Werkzeugen bewaffnet werden, um zurückzuschlagen? Anhand von über 100 Klagen afghanischer Schutzsuchender zeigen wir, wie Ministerien das Bundesaufnahmeprogramm sabotieren, Gerichte sie zurückpfeifen – und die Zivilgesellschaft zum letzten Schutzwall des Rechtsstaats wird. Und wir verraten, warum sich Beamte im BAMF vielleicht lieber krankmelden sollten und welche anderen Möglichkeiten sie haben, um nicht straffällig zu werden.
Excuse me, what precise time is It? (en)

Oliver Ettlin

With PTP 1588, AES67, and SMPTE 2110, we can transmit synchronous audio and video with sub-millisecond latency over the asynchronous medium 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? Precision Time Protocol (IEEE 1588) tries to do just that. It's the invisible backbone of realtime media standards like AES67 and SMPTE 2110, proprietary technologies such as Dante, and even critical systems powering high-frequency trading, cellular networks, and electric grids.
Doomsday-Porn, Schäferhunde und die „niedliche Abschiebung“ von nebenan: Wie autoritäre Akteure KI-generierte Inhalte für Social Media nutzen (de)

Katharina Nocun

Der amtierende US-Präsident postet ein Video, in dem er Demonstrierende aus einem Kampfjet heraus mit Fäkalien bewirft und das Weiße Haus zelebriert den „Star Wars Day“ mit einem pompösen Trump-Bild mit Lichtschwert. Accounts von AfD-Sympathisanten posten KI-Kitsch einer vermeintlich heilen Welt voller blonder Kinder und Frauen im Dirndl. Ist das lediglich eine geschmackliche Entgleisung oder steckt da mehr dahinter?
Breaking architecture barriers: Running x86 games and apps on ARM (en)

Tony Wasserka

Presenting FEX, a translation layer to run x86 apps and games on ARM devices: Learn why x86 is such a pain to emulate, what tricks and techniques make your games fly with minimal translation overhead, and how we are seamless enough that you'll forget what CPU you're using in the first place!

Hatupangwingwi: The story how Kenyans fought back against intrusive digital identity systems (en)

Mustafa Mahmoud Yousif

The session title is fashioned after the Kenyan movement building rhetoric “Hatupangwingwi” which is Kenyan slang meant as a call to action 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. The session 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.
Suing spyware in Europe: news from the front! (en)

Lori Roussey, Celia/Irídia

In 2022, CitizenLab contacted a member of the Spanish non-profit Irídia to tell them that one of their members had likely been hacked with Pegasus spyware. The target, a lawyer, had been spied on by the Spanish government in 2020 because he represented a Catalan politician who was in prison. His phone was infected with Pegasus during the COVID-19 lockdown, on the same day he was having an online meeting with other lawyers working on the case. Irídia and the lawyer (Andreu) decided to take the case 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 impact. This collaboration led to the creation of the PEGA coalition in May 2025. This talk goes over the status of the case and work we have done across Europe to bring spyware use in court.
Burn Gatekeepers, not Books! (de)

tomate, jinxx

*Der deutsche Buchmarkt gegen den Rest der Welt oder auch: Enshittification des Buchmarkts und keine API für ein Halleluja* Es gibt unzählige wundervolle Geschichten und das Internet hat über die letzten Jahrzehnte viele großartige Autor*innen hervorgbracht. Doch Verlage haben begrenzte Kapazitäten und sind außerdem zumeist sehr konservativ in ihren Programmen. Die Lösung für beides: Selfpublishing. Neue und gewitzte, genre-übergreifende Bücher an neugierige Lesende zu bringen, könnte so einfach sein; wären da nicht Barsortimente, fehlende APIs und ein insgesamt schreckliches Ökosystem, die Indie-Autor:innen (und alle, die versuchen, auf dem deutschpsprachigen Buchmarkt irgend etwas Innovatives für Indies zu machen) das Leben schwer machen.
Current Drone Wars (en)

Leonard

The character of drone wars has changed. The large, cumbersome long-range drones have been complemented with small and low-budget drones. Moreover, more and more states are developing, deploying and selling them. Ten years ago at least 50 states were developing them. At the top are USA, Israel, Turkey, China, Iran and Russia. Russia's attack on Ukraine has unleashed a drone war unlike any seen before. In short time the Ukraine has build significant drone production capabilities and announcement that it will increase its own production of quadcopters and kamikaze drones to one million units per year. German defense companies and startups are now promoting a “drone wall on NATO's eastern flank.” Moreover, despite their vulnerability to air defenses, large drones are also being further developed. They are intended to accompany next generation fighter jets in swarms. In this talk, past and current developments are discussed. What are the perspectives now?
CPU Entwicklung in Factorio: Vom D-Flip-Flop bis zum eigenen Betriebssystem (de)

PhD (Philipp)

Factorio ist ein Fabriksimulationsspiel mit integriertem Logiksystem. Dies ermöglichte mir den Bau einer CPU, die unter anderem aus einer 5-stufiger Pipeline, einer Forwarding Logikeinheit, Interrupt Handling sowie einem I/O Interface besteht. Über einen selbst geschriebenen Assembler konnte ich ein eigenes Betriebssystem und Programme wie Minesweeper oder Snake integrieren. Der Talk soll euch zeigen, wie sich klassische Computerarchitektur in einem völlig anderen technischen Kontext umsetzen lässt und wo dabei überraschend echte Probleme der CPU-Entwicklung auftreten. Kommt mit auf die Reise: Vom Blick auf den gesamten Computer bis hinunter zu den einzelnen Logikgattern ist es nur eine Mausradbewegung entfernt!
Textiles 101: Fast Fiber Transform (en)

octoprog

Textiles are everywhere, yet few of us know how they’re made. This talk aims to give you an overview over the complete transformation from fiber to finished textile. We'll be exploring fiber properties, spinning, and techniques like weaving, knitting, crochet, braiding, and knotting, followed by finishing methods such as dyeing, printing, and embroidery. You’ll learn why not only fiber but also structure matters, and how to make or hack textiles on your own without relying on fast fashion or industrial tools.
Reverse engineering the Pixel TitanM2 firmware (en)

willem

The TitanM2 chip has been central to the security of the google pixel series since the Pixel 6. It is based on a modified RISC-V design with a bignum accelerator. Google added some non standard instructions to the RISC-V ISA. This talk investigates the reverse engineering using Ghidra, and simulation of the firmware in python.
Design for 3D-Printing (en)

rahix

3D-Printers have given us all the unprecedented ability to manufacture mechanical parts with a very low barrier to entry. The only thing between your idea and its physical manifestation is the process of designing the parts. However, this is actually a topic of incredible depth: Design engineering is a whole discipline to itself, built on top of tons and tons of heuristics to produce shapes that are functional, strong, and importantly: well-manufacturable In this talk, I will present the rules for designing well-printable parts and touch on other areas of design considerations so you can learn to create parts that work first try and can be reproduced by others on their 3d-printers easily.

Aber hier Leben? Nein danke! …oder doch? Wie wir der autoritären Zuspitzung begegnen können. (de)

Jaša Hiergeblieben, Polylux, Lisa Zugezogen

Im Osten stehen nächstes Jahr schon wieder Wahlen an und schon wieder sieht alles danach aus, als ob die AfD eine Regierungsbeteiligung bekommen könnte. Ganz konkret: In Sachsen-Anhalt und Mecklenburg-Vorpommern. Nicht nur diese "rosigen" Aussichten, sondern auch aktuelle Bevölkerungsprognosen werfen gar kein günstiges Licht auf die Regionen. Linke Akteur:innen vor Ort kämpfen täglich dagegen an und sie brauchen unsere Solidarität. Wir müssen dem etwas entgegensetzen. Egal ob als Hacker:innen auf dem Congress oder Westdeutsche in (noch) Grünen Gemeinden. Wo kommt das alles her? Wer macht aktuell etwas dagegen und wie können wir dem rechten Sog begegnen?
The Heartbreak Machine: Nazis in the Echo Chamber (de)

Martha Root, Eva Hoffmann, Christian Fuchs

WhiteDate ist eine Plattform weißer Suprematist:innen, die sich an Rassist:innen und Antisemit:innen richtet – und auf veralteter Infrastruktur basiert. Was die 8000 Mitglieder nicht wussten: Einige der Nazis flirteten dieses Jahr mit realistisch wirkenden Chatbots - und verliebten sich sogar in sie. Mit einer Kombination aus automatisierter Konversationsanalyse, Web-Scraping und klassischen OSINT-Methoden verfolgten wir öffentliche Spuren und identifizierten die Personen hinter der Seite. Dieser Vortrag zeigt, wie KI-Personas und investigatives Denken extremistische Netzwerke aufdecken und wie Algorithmen gegen Extremismus eingesetzt werden können.
Peep-Show für die Polizei. Staatliche Überwachung von Queers in Hamburger Toiletten bis 1980 (de)

Simon Schultz

Oder: Wie die Hamburger Polizei queere Menschen auf öffentlichen Toiletten observierte, und wie ein anonymes Kollektiv im Juli 1980 dieses Überwachungsystem wortwörtlich mit dem Hammer zerschlagen hat. Ein analoger Überwachungskrimi mit sauberen Städten, lichtscheuen Elementen, queerem Aktivismus, und kollektiver Selbstorganisation; und mit einer Anleitung wie man Beamten Anfang der 80er das Handwerk legen konnte.
Verschlüsselung brechen durch physischen Zugriff - Smartphone Beschlagnahme durch Polizei (de)

Davy Wang, Viktor Schlüter

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 Sicherheitslücken der Geräte mithilfe forensischer Software von Herstellern wie Cellebrite oder Magnet aus. Die Verfassungsmäßigkeit der Rechtsgrundlagen ist zweifelhaft. Im Vortrag werden anhand aktueller Fälle technische und juristische Hintergründe erörtert.

Who runs the www? WSIS+20 and the future of Internet governance (en)

Sophia Longwe

Abbreviations such as WSIS+20, IGF, IETF, DIEM, ICANN, PDP, ITU or W3C regularly appear in discussions about the Internet, yet often remain vague. This talk provides an update on the current state of Internet governance and explains why decisions made in United Nations processes have direct implications for technical standards, digital infrastructure, and power asymmetries.

ISDN + POTS Telephony at Congress and Camp (en)

Harald "LaF0rge" Welte

Like 39C3, the last CCC camp (2023) and congress (38C3) have seen volunteer-driven deployments of legacy ISDN and POTS networks using a mixture of actual legacy telephon tech and custom open source software. This talk explains how this is achieved, and why this work plays an important role in preserving parts of our digital communications heritage.
FeTAp 611 unplugged: Taking a rotary dial phone to the mobile age (en)

Michael Weiner

This project transforms a classic rotary phone into a mobile device. Previous talks have analyzed various aspects of analogue phone technology, 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 generator - but still maintains the classical look and feel. The talk demonstrates the journey of bridging analog and digital worlds, explaining how careful design connects a vintage phone to today’s mobile environment - in a way that will make your grandparents happy.
„KI“, Digitalisierung und Longevity als Fix für ein kaputtes Gesundheitssystem? (de)

Manuel Hofmann

Großen Herausforderungen im Gesundheitswesen soll mittels Technik und Eigenverantwortung begegnet werden. Die Hoffnung: „KI“ und Digitalisierung machen das System effizienter; Selbstoptimierung und mehr Eigenverantwortung halten die Menschen länger gesund. Der Vortrag analysiert aktuelle Diskurse rund um Digitalisierung und Gesundheit, und fragt kritisch, wie diese Entwicklung ohnehin bestehende soziale Ungleichheiten verschärfen könnte. Am Ende bleibt die Frage: Wie könnten tragfähige Lösungen fürs Gesundheitssystem aussehen?

A 595€ wheelchair remote that sends a handful of Bluetooth commands. A 99.99€ app feature that does exactly what the 595€ hardware does. A speed upgrade from 6 to 8.5 km/h locked behind a 99.99€ paywall - because apparently catching the bus is a premium feature. Welcome to the wonderful world of DRM in assistive devices, where already expensive basic mobility costs extra and comes with in-app purchases! And because hackers gonna hack, this just could not be left alone.

A spectre is haunting Europe—the spectre of bureaucracy. All the Powers of old Europe have entered into an unholy alliance to exorcise this spectre: The EU Commission, Member States, industry, even J.D. Vance. This threatens the digital rights and rules built up in the last decade.
Live, Die, Repeat: The fight against data retention and boundless access to data (en)

Klaus Landefeld

Both within the EU as well as nationally in Germany, there exists a renewed drive to implement data retention, a practice struck down by the ECJ and discontinued in many national legislations. In parallel, cross-border access to stored data has been mandated within the EU as “e-evidence”, and will soon be extended to 90+ countries under the umbrella of the EU cybercrime convention. In principle, all data stored by service providers will be available to law enforcement as part of a criminal investigation. The timing of both initiatives is not coincidental, as access to data naturally relies on the availability of data. The talk will address the state of play on data retention in various legislations, and introduce the practice of cross border access to stored data by law enforcement as well as its shortcomings and threats to privacy and confidentiality.

Lessons from Building an Open-Architecture Secure Element (en)

Jan Pleskac

The talk will be about our experience from building an open-architecture secure element from the ground up. It explains why openness became part of the security model, how it reshaped design and development workflows, and where reality pushed back — through legal constraints, third-party IP, or export controls. It walks through the secure boot chain, attestation model, firmware update flow, integration APIs, and the testing framework built for external inspection. Real examples of security evaluations by independent researchers are presented, showing what was learned 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.
Amtsgeheimnis raus, Datenhalde rein: was die Informationsfreiheit in Österreich bringt (de)

Markus (fin) Hametner, Erwin Ernst "eest9" Steinhammer

Jahrelang war die staatliche Intransparenz in Österreich nur eine Punchline in den Congress-Talks von Frag Den Staat. Damit könnte jetzt Schluss sein: seit heuer haben Bürger:innen endlich ein Recht, Dokumente einzusehen und ein Informationsfreiheitsgesetz. Wir zeigen, was Deutschland aus der über ein Jahrzehnt andauernden Kampagne für die Abschaffung des Amtsgeheimnisses lernen kann, wofür uns die Nachbarländer beneiden werden und wofür sich Bayern besonders schämen sollte.

Human microservices at the Dutch Railways: modern architecture, ancient hardware? (en)

Maarten W

The Dutch railways have been operating an increasingly complicated 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 introduced into the system, but today there is still a significant role for humans. This 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.

OpenAutoLab, an open source machine, that is capable of processing contemporary color and black-and-white films for analogue photography, is being presented here. It made its first public appearance at 37C3 and 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 people and to be further developed by the community. This talk is about motivation behind developing OpenAutoLab and about the technical decisions made during it. It is argued that any dedicated film photographer is able to get one built.

From Silicon to Darude Sand-storm: breaking famous synthesizer DSPs (en)

giulioz

Have you ever wondered how the chips and algorithms that made all those electronic music hits work? Us too! At The Usual Suspects we create open source emulations of famous music hardware, synthesizers and effect units. After releasing some emulations of devices around the Motorola 563xx DSP chip, we made further steps into reverse engineering custom silicon chips to achieve what no one has done before: a real low-level emulation 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 the device used, which ran software written with a completely undocumented instruction set. In this talk I will go through the story of how we overcame that obstacle, using a mixture of automated silicon reverse engineering, probing the chip with an Arduino, statistical analysis of the opcodes 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.

selbstverständlich antifaschistisch! Aktuelle Informationen zu den Verfahren im Budapest-Komplex - von family & friends Hamburg (de)

Andreas family & friends Hamburg, Birgit family & friends Hamburg

Mit den Prozessen im Budapest-Komplex wird ein Exempel statuiert - nicht nur gegen Einzelne, sondern gegen antifaschistische Praxis insgesamt. Die Behauptung einer kriminellen Vereinigung mit Mordabsichten stellt eine absurde juristische Eskalation des staatlichen Vorgehens gegen Antifaschist*innen dar und steht in keinem Verhältnis zu den verhandelten Vorkommnissen. Die Verfahren in dieser Weise zu verfolgen, lässt vor allem auf ein hohes Ausforschungs- und Einschüchterungsinteresse schließen. Mit dieser Prozesswelle und den Repressionen gegen Freund*innen und Angehörige wird antifaschistisches Engagement massiv kriminalisiert und ein verzerrtes Bild von politischem Widerstand gezeichnet - während gleichzeitig rechte Gewalt europaweit zunimmt und faschistische Parteien erstarken. Wir sehen, dass Angriffe auf Rechtsstaatlichkeit und Zivilgesellschaft immer weiter zunehmen. Die Art und Weise, wie gegen die Antifas im Budapest-Komplex und im Antifa-Ost Verfahren vorgegangen wird ist ein Vorgeschmack darauf, wie politische Opposition in einer autoritären Zukunft behandelt werden könnte. Wir sind alle von der rechtsautoritären Entwicklung, von Faschisierung betroffen. Die Kriminalisierung von Antifas als "terroristische Vereinigung" ist Teil einer (weltweiten) Entdemokratisierung und Zersetzung von Rechtsstaatlichkeit.
Trump government demands access to European police databases and biometrics (en)

The USA is demanding from all 43 countries in the "Visa Waiver Programme" (VWP), which enables visa-free travel, to conclude an "Enhanced Border Security Partnership" (EBSP). This is intended to grant US authorities direct access to police databases in these - mostly European - countries containing fingerprints, facial images and other personal data. Anyone who refuses this forced "border partnership" faces exclusion from the visa-free travel programme.

The Last of Us - Fighting the EU Surveillance Law Apocalypse (en)

Svea Windwehr, Chloé Berthélémy

The virus of surveillance is spreading across the European Union. In the form of its "ProtectEU" Internal Security Strategy, the European Commission is planning to attack encryption, re-introduce mandatory data retention and strengthen Europol and Frontex, the main agents of its oppressive law enforcement infrastructure. In this talk, we will journey the wastelands of the EU surveillance apocalypse together: We will take a close look at what politicians are planning to undermine our fundamental rights, the technology involved, and the real harms we must fight. From there, we will chart pathways to resistance and collective immunity against a surveillance agenda that requires us to form new alliances and re-think mobilization.
How to keep Open Source open without leaving our communities open to threats (en)

Quintessence

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 ethos still applies today, the cultural norms that blossomed to put it into practice are from an era with different challenges. To build a better world, we need to both keep and protect the value system of the Four Freedoms and Four Opens. To do that, we need to re-assess our risk and threat models to balance that allows beautiful minds to flourish as well as introduce responsible friction to prevent harm from coming to them.
Laser Beams & Light Streams: Letting Hackers Go Pew Pew, Building Affordable Light-Based Hardware Security Tooling (en)

Patch, Sam. Beaumont (PANTH13R)

Stored memory in hardware has had a long history of being influenced by light, by design. For instance, as memory is represented by the 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, in preparation for flashing new memory. Naturally, whilst useful, this has proven to be an avenue of opportunity to be leveraged by attackers, allowing them to selectively influence memory via a host of optical/light-based techniques. As chips became more advanced, the usage of opaque resin was used as a "temporary" measure to combat this flaw, by coating chips in a material that would reflect UV. Present day opinions are that laser (or light) based hardware attacks, are something that only nation state actors are capable of doing Currently, sophisticated hardware labs use expensive, high frequency IR beams to penetrate the resin. This project demonstrates that with a limited budget and hacker-and-maker mentality and by leveraging more inexpensive technology alternatives, we implement a tool that does laser fault injection, can detect hardware malware, detect supply chain chip replacements, and delve into the realm of laser logic state imaging.

RSS Disco’s timeline approach celebrates this continuum: a story of machines learning to groove, and humans learning to listen differently through them.

Finally a drag show at the chaos! Blinking lights, colorful outfits, and queers everywhere already seems normal at the congress. So how 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! And to show right 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 audience. The 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 year. And he is bringing an amazing cast with him Bingus Bongus (Drag Queen, Hamburg) Neuro Spicy (Drag King, NRW) Missass Nostalgia (Drag Queen, NRW) and Kaín Mensch (Drag Thing, Hamburg) will bring their queer art to finally merge chaos and drag! Everyone is welcome, we are trying to have as little barriers as possible to come and watch. No blinking lights during the show (no guarantee for the path there and acts before and after), Music Club accessible with mobility aids and wheel chairs (ask assigned 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 include death, cancer, violence, fake weapons, and sexual violence, and 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 to find a spot where they can see enough. Also, as drag is expensive, there will be a tipping round in the end - please bring some cash if you consider tipping the artists, but of course you are also welcome either way.

Rob StrobE

THE SECOND DECADE Born `78 in Germany Rob StrobE grew up and being influenced with classical music, swing and jazz in his childhood. He early discovered the likes of Depeche Mode, Michael Jackson, Kraftwerk and more early electronic music approaches. In his late youth/early adult life he frequently travelled to Frankfurt attending nights at the Omen. Those nights and weekends were filled with DJs like Sven Vaeth, Dj Rush, Chris Liebing, G-Man aka Gez Varley, Hardfloor and so many more, celebrating and transporting the spirit of those days! After 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. Around the year 2002 he started music production - mostly for personal fun and recreational purposes - but some records and remixes have been released since then...some of this older work can still be found on his Soundcloud! Since then he developed his own company specialized on music studio technology, room acoustic, signal flow schemes and studio furniture. Meanwhile his own studio transformed from a small Home Studio to a „room-in-room“ environment in the Logic Haus - the former home of Harthouse, Eye-Q and Snap! If he had to describe his musical style and give it a name: it would be „DubHouseTechno with a pinch of Detroit" ;) 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 swap 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 visit on his social media outlets and say „hello“! THANKS FOR YOUR SUPPORT!!!

The Uncontrolled Manifold : dancing with sympoetic machines (de)

Christian Faubel

The Uncontrolled Manifold works with electronics and machines that possess autonomy and obstinacy. These machines are brought into interaction with each other, creating danceable polyrhythms and, at the same time, a fascinating shadow play, because the machines are mounted on an overhead projector and their interaction is projected. Analog oscillators generate self-organizing coordination dynamics and organic patterns, while motors strike rubber strings producing deep, resonant bass sounds reminiscent of shamanic drumming. Supported by the visuals spectators may feel like being dragged into the vortex of a living clock, compelled to join the performance through movement and dance.

Dj Sloush + Zarrt (de)

Dj Sloush aka Spitz + Zarrt

The berlin based artist duo is working under different alias solo, in duos or collectives since 2011. They are sound artists, DJs, part of Cashmere Radio (Berlin), curators, event organizers, performers and multimedia artists. “Dj Sloush aka Spitz + Zarrt aka Fellmaus will make you happy. There’s gonna be these sounds coming from the speakers, new otherworldly ones mixed with seemingly familiar yet undiscovered natural feeling waves of moods, or maybe hot and twirling rapid fire bass jumping trippin balls ones. Either way they’ll provide you with a guaranteed enjoyment of the infinite kind.”

Babooshka

Babooshka is Marian Bodenstein, who played with several punk bands such as LASSIE, LAFFF BOX, NICK NORMAL and DBR at the moment. Under the moniker FUZZZGUN Marian is working as a graphic designer for bands, labels and other "multinational corporations". Normally Babooshka would serve you a high octane dance set rooted in 70s power pop, punk and rocknroll but for the CCCChillfloor you’ll get a certain mixture of their favorite relaxin, beautiful and tearjerking tracks, combined with some broken records to serve as analog loops and audioplay records. Babooshka is happy to play records that are normally reserved for the end of an emotional night of dance and shenanigans or even never would see the lights of the dance floor under „normal“ circumstances.

WEEBZ likes to move between the odds, the rough and the soft: Breakbeat, dissonances, noise and sounds of deep dungeons belong to their mixes as well as the hymns of our hearts Most of the time the genres are mixed to an eclectic collection mirroring own confusions in the spirit of making the unmatching matching xx

Felix Kubin (de)

Felix Kubin

Felix Kubin, funkensprühender Spannungs- und Weltenwandler aus Hamburg, Verachter der Nüchternheit, lenkt die musikalische Kompassnagel Richtung Stolperdisko, Art Pop und „gute Nervmusik“. Das Tanzbein zappelt, aber die Beine laufen in verschiedene Richtungen, denn sie haben sich noch nicht synchronisiert. Hier erklingen Songs am Rande des Nervenzusammenbruchs, "Musik für junge Leute" und alle, die nicht sterben wollen. Vor allem haben es ihm die obskuren Musikversuche der Heimstudios vergangener Fostex-Generationen angetan, die Art Brut und ihre Einfärbungen durch billige, leicht zu demolierende Technologien. Felix Kubins musikalische Adoleszenz wurde durch eine Zeit geprägt, in der sich die Szenen der Kunst und Musik stark durchdrangen und Songtitel wie "Die Gesunden kommen", "Adrenalin lässt das Blut kochen" und "Hosen, die nicht aneinander passen" kein Stirnrunzeln verursachten. Eine Zeit also, in der sich die Popmusik weit aus dem Fenster lehnte und die Luft einer fremden, seltsamen Welt atmete.

Der feine Schliv (de)

Der feine Schliv

Zwischen Rap, Tanz und Poesie, erschließt Der feine Schliv neue Räume. In ihren Performances changiert sie zwischen provokanten Auf-die-Fresse-Ansagen an das Patriarchat und empathischen Erzählungen vom Versuchen und Scheitern. Sie tritt unter anderem mit dem serbischen Nachwuchs Duo “Slezga” sowie mit den Hamburger Gruppen “Fallbeil” und “Yummy Air”auf. An der Diverstität ihrer Begleitungen zeichnet sich ihr musikalisches Universum ab, von balladigen Conscious Raps, Chansons und Witchy Toasting.

Der verlängerte Atem pres. Ghost Processes (de)

Martin, Fiona, Jil

Der verlängerte Atem pres. Ghost Processes Seit 2020 sendet Der verlängerte Atem regelmäßig auf HALLO:Radio und tourt mit Gastauftritten auf Festivals und Veranstaltungen in und um Hamburg. Als offenes Radiolabor zwischen Musik, Redebeiträgen und thematisch passenden Audio-Snippets, verweben die Vinyl-DJs, Künstlerinnen und Radiomacherinnen Fiona Grassl, Jil Lahr und Martin Ramacher analoge Klänge, Stimmen und Gedanken zu thematischen Sendungen. Für den 39C3 fährt Der Verlängerte Atem das System herunter - und wieder hoch. Und findet dazwischen: Prozesse ohne Besitzer, Threads ohne Aufgaben, Routinen, die längst beendet sein sollten und doch weiterlaufen. Geisterprozesse flüstern im Hintergrund, aktualisieren sich selbst, verlieren den Takt oder schlafen zu tief, um je zurückzukehren. Zwischen knisterndem Vinyl, digitalem Summen, Glitches und verspielten Redebeiträgen entstehen live Sound-Landschaften, in denen nichts ganz verschwindet - und alles wiederkehrt. Spooky.
Cloud Management (de)

Cloud Management

Operating in a mode of Kluster via Pole, Dub Syndicate at Conny Plank's, or even fang-baring flashes of The Bug and Bryn Jones or Peak Oil modernism, the trio approach the project from the more oblique angles of respective projects Datashock, Phantom Horse and Love-Songs, to probe a more soft-centred, dematerialised and heady sound, but also reserve the right to go tuffer, more venomous, when they feel it.
