Code to Craft: Procedural Generation for the Physical World (39c3)
Join bleeptrack for a deep dive into the fascinating world of procedural generation beyond the screen. From stickers and paper lanterns to PCBs, furniture, and even physical procedural generators, this talk explores the challenges and creative possibilities of bringing generative projects into tangible form. In this talk, I will share practical insights from developing procedural generation tools for physical objects: ranging from stickers and paper lanterns to printed circuit boards and even furniture. I will outline key challenges and considerations when generating designs for fabrication tools such as laser cutters or pen plotters, as well...
Trump government demands access to European police databases and biometrics (39c3)
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 US demand is unprecedented: even EU member states do not grant each other such extensive direct database access – normally the exchange takes place via the "hit/no-hit...
When Vibe Scammers Met Vibe Hackers: Pwning PhaaS with Their Own Weapons (39c3)
What happens when AI-powered criminals meet AI-powered hunters? A technical arms race where both sides are vibing their way through exploitation—and the backdoors write themselves. In October 2025, we investigated Taiwan's fake delivery scam ecosystem targeting convenience store customers. What started as social engineering on social media became a deep dive into two distinct fraud platforms—both bearing the unmistakable fingerprints of AI-generated code. Their developers left more than just bugs: authentication flaws, file management oversights, and database implementations that screamed "I asked LLM and deployed without reading." We turned their sloppiness into weaponized OSINT. Through...
1965 + 60 Years of Algorithmic Art with Computers (39c3)
What power structures are inherent to the field of computer-generated art? In the year 1965, so 60 years ago, the first three exhibitions of art created with the help of computers took place - in part independently of each other. We want to present the interesting aspects of developments since then and discuss them with Frieder Nake, one of the people who exhibited in those very beginnings and followed those developments with a critical attitude. We want to look at the complex topic of art created with computers, beginning with some careful and barely noticed...
Life on Hold: What Does True Solidarity Look Like Beyond Duldung, Camps, Deportation, and Payment Cards? (39c3)
Lager, Duldung, Bezahlkarte, Essensscheine – Criminalization, Radicalization, Reality for Many People in East Germany This talk sheds light on how these terms shape everyday life. We dive into an existence marked by uncertainty, isolation, and psychological strain, both in anonymous big cities and rural areas of East Germany. We ask: What does “solidarity” really mean in this context? In this session, people share everyday experiences with a system that often systematically undermines human rights and dignity. We don’t just talk about the obvious obstacles like the payment card or residency obligation, but also the invisible wounds: the...
Landtagsrevue Live - AUA (Ask us Anything) (39c3)
Live-Sonderausgabe der Landtagsrevue - dem Landespolitik-Ableger der Parlamentsrevue.
Wir schauen zurück auf das erste Jahr der Landtagsrevue und beantworten eure Fragen rund um die Parlamente - wie funktioniert das eigentlich alles? Wo können wir als Zivilgesellschaft am besten Einfluss nehmen? Wer sind all diese Leute?? Schickt uns eure Fragen gern vorab an landtag@parlamentsrevue.de - so können wir auch Antworten aus den Ländern mitbringen, die nicht live dabei sind.

The Eyes of Photon Science: Imaging, Simulation and the Quest to Make the Invisible Visible (39c3)
Science advances by extending our senses beyond the limits of human perception, pushing the boundaries of what we can observe. In photon science, imaging detectors serve as the eyes of science, translating invisible processes into measurable and analysable data. Behind every image lies a deep understanding of how detectors see, respond and perform. At facilities like the European XFEL, the world's most powerful X-ray free-electron laser located in the Hamburg metropolitan area, imaging detectors capture ultrashort X-ray flashes at MHz frame rates and with high dynamic range. Without these advanced detectors, even the brightest...
Of Boot Vectors and Double Glitches: Bypassing RP2350's Secure Boot (39c3)
In August 2024, Raspberry Pi released their newest MCU: The RP2350. Alongside the chip, they also released the RP2350 Hacking Challenge: A public call to break the secure boot implementation of the RP2350. This challenge concluded in January 2025 and led to five exciting attacks discovered by different individuals. In this talk, we will provide a technical deep dive in the RP2350 security architecture and highlight the different attacks. Afterwards, we talk about two of the breaks in detail---each of them found by one of the speakers. In particular, we first discuss how fault injection...
Coding Dissent: Art, Technology, and Tactical Media (39c3)
This presentation examines artistic practices that engage with sociotechnical systems through tactical interventions. The talk proposes art as a form of infrastructural critique and counter-technology. It also introduces a forthcoming HackLab designed to foster collaborative development of open-source tools addressing digital authoritarianism, surveillance capitalism, propaganda infrastructures, and ideological warfare. In this talk, media artist and curator Helena Nikonole presents her work at the intersection of art, activism, and tactical technology — including interventions into surveillance systems, wearable mesh networks for off-grid communication, and AI-generated propaganda sabotage. Featuring projects like Antiwar AI, the 868labs initiative, and the...
Doomsday-Porn, Schäferhunde und die „niedliche Abschiebung“ von nebenan (39c3)
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? KI-generierter Content ist aus der Kommunikationsstrategie autoritärer Akteure nicht mehr wegzudenken. Social Media wird derzeit mit rechtem KI-Slop geflutet, in dem wahlweise die Welt dank Migration kurz vor dem Abgrund steht oder blonde, weiße Familien fröhlich...
