GPTDash – Der Reverse-Turing-Test (39c3) Video 29.12.2025

KIs (bzw. LLMs) wirken immer menschlicher. Schon längst ist es schwer bis unmöglich zu erkennen, ob ein Text von einer KI oder einem Menschen geschrieben wurde. Maschinen dringen immer mehr in den menschlichen Diskurs ein. Wir wollen das nicht länger hinnehmen und drehen den Spieß um. In unserem Reverse-Turing-Test schlüpfen die Teilnehmenden in die Rolle einer KI und versuchen so robotisch-mensch...

The Small Packet of Bits That Can Save (or Destabilize) a City (39c3) Video 28.12.2025

The Emergency Alert System (EAS) and its SAME (Specific Area Message Encoding) protocol are public alerting technologies that broadcast short digital bursts over VHF triggering emergency messages on millions of receivers across North America.

51 Ways to Spell the Image Giraffe: (39c3) Video 28.12.2025

Generative AI models don't operate on human languages – they speak in **tokens**. Tokens are computational fragments that deconstruct language into subword units, stored in large dictionaries. These tokens encode not only language but also political ideologies, corporate interests, and cultural biases even before model training begins. Social media handles like *realdonaldtrump*, brand names like...

Xous: A Pure-Rust Rethink of the Embedded Operating System (39c3) Video 28.12.2025

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 o...

When Vibe Scammers Met Vibe Hackers: Pwning PhaaS with Their Own Weapons (39c3) Video 28.12.2025

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...

How To Minimize Bugs in Cryptography Code (39c3) Video 28.12.2025

"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 cryptography 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 will give a peek into the cryptographer's toolbox of advanced techniques to avoid bugs: targeted testing, model checki...

You’ll learn why not only fiber but also st...

Don’t look up: There are sensitive internal links in the clear on GEO satellites (39c3) Video 28.12.2025

We pointed a commercial-off-the-shelf satellite dish at the sky and examined all of the geostationary satellite communications visible from our vantage point. A shockingly large amount of sensitive traffic is being broadcast unencrypted, including critical infrastructure, internal corporate and government communications, private citizens’ voice calls and SMS, and consumer Internet traffic from in-...

Machine Vision (39c3) Video 28.12.2025

Milliarden von Kameras produzieren täglich Bilder, die zunehmend von Maschinen analysiert werden.

Trump government demands access to European police databases and biometrics (39c3) Video 28.12.2025

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 partners...

Amtsgeheimnis raus, Datenhalde rein (39c3) Video 28.12.2025

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 di...

How to render cloud FPGAs useless (39c3) Video 28.12.2025

While FPGA developers usually try to minimize the power consumption of their designs, we approached the problem from the opposite perspective: what is the maximum power consumption that can be achieved or wasted on an FPGA? Short answer: we found that it’s easy to implement oscillators running at 6 GHz that can theoretically dissipate around 20 kW on a large cloud FPGA when driving the signal to a...

CPU Entwicklung in Factorio (39c3) Video 28.12.2025

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.
