Asahi Linux - Porting Linux to Apple Silicon (39c3)

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...
Security Nightmares (39c3)

Was hat sich im Jahr 2025 im Bereich IT-Sicherheit getan? Welche neuen Methoden, Buzzwords und Trends waren zu sehen? Was waren die fiesesten Angriffe und die teuersten Fehler?
Wir wagen auch den IT-Security-Ausblick auf das Jahr 2026. Der ist wie immer mit Vorsicht zu genießen.

Breaking BOTS: Cheating at Blue Team CTFs with AI Speed-Runs (39c3)

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 instead of taking the full day. Our recipe was surprisingly simple: Teach AI agents to self-plan their investigation steps, adapt their plans to new information, work with the SIEM DB, and reason about log dumps. No exotic models, no massive lab budgets - just publicly available LLMs mixed with a bit of science and perseverance. We'll...
39C3: Power Off zur Abreise!

Liebe Wesen und Teilnehmende,
das Ende ist nahe! Tage voller Begegnungen, Neugier, Lötzinn, Diskurs, Musik, Code und Chaos liegen hinter uns. Danke, dass ihr diesen Congress mit Leben gefüllt habt. Ihr habt ihn zu dem gemacht, was er ist.
So sehr wir uns wünschen, dass der Congress ewig weiterläuft, kommt nun der Moment des Zusammenpackens, Durchatmens und Abschiednehmens.
Nach dem Closing beginnen die Assemblies damit, ihre Räume wieder zu leeren. Bitte nehmt euch die Zeit, ordentlich und achtsam abzubauen. Räumt möglichst schnell eure Tische frei, damit das Möbelhaus Tische und Stühle abtransportieren kann und Netzwerk und Strom abgebaut werden können. Die Hardware für...
FAFO: How we stopped worrying and bought an Electron Microscope (39c3)

We went on Kleinanzeigen and started a non-profit semiconductor lab.
We created a space to do the kind of research we've always wanted, but couldn't do at our local hackerspaces - either due to space constraints, or lack of structures allowing for a safe operation of a proper lab.

The Modular Workshop – The Tunegirl und Rob StrobE (39c3)

Hallo CCC Community, wir präsentieren euch The Tunegirl und Rob StrobE, beide sind mit Veröffentlichungen auf dem Assassins Soldier Label beheimatet und blicken auf eine gemeinsame Liebe für Detroit Techno. Die Idee zum gemeinsamen Workshop für euch entstand natürlich auf dem Dancefloor und The Tunegirl hat die Cases gepackt und nach Hamburg gebracht. Während The Tunegirl den praktischen Teil verantwortet und die Kabel steckt, wird euch Rob durch die Kabel führen und einen Einblick in die Welt der Module und Drummachines geben. Unterstützt wird das ganze von einer Kamera, damit ihr nah am Geschehen dabei sein...
Light in the Dark(net) (39c3)

Science is hard and research into the usage of the Tor network is especially so. Since it was designed to counter suveillance, it gathering reliable information is difficult. As a consequence, the studies we do have, have yielded very different results. This talk investigates the 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 last bastion of freedom or a haven of crime, this talk will tell you where to look...
Block Domains and Advertisements in a ZTE DSL Router

In one of my previous blog posts I showed how to install and run PiHole DNS server locally as a Docker container in your Synology NAS server. This worked great as the PiHole dashboard shows the list of identified annoying advert requests that were blocked shows.
So far I did configure my PiHole DNS server within my Chrome browser so that the browser cant load those annoying domains anymore. This worked like a charm, until quite recently Google updated Chrome browser to only allow a ‘secured DNS connection’ which actually seems a bit of a trojan horse for their own ads...
OpenTelemetry Astroshop Simulator

Astroshop is a great way of testing and running a demo scenario that offers with a large spectrum of technologies, services and a realistic problem scenario of running a real shop in serverless or Kubernetes infrastructure.
Besides, Astroshop being a great way to demo and test observability platforms such as Dynatrace and to run problem scenarios on demand, its also a bit cumbersome to deploy it for testing purposes. Imagine that you are a local developer that just needs to quickly run a test for a new feature using OTel traces and spans. Deploying Astroshop or any other scenario always comes...
ChaosPager: Teste unsere Pager‑Infrastruktur!
Du findest Pager toll? Dich interessiert, wie man eine kritische Infrastruktur konzipiert, oder du möchtest solche Systeme am 39C3 kennenlernen? Du suchst einen einfachen Einstieg in die Welt des Amateurfunks?
Wir vom Assembly Signalspielplatz entwickeln und betreiben in Kooperation mit dem CERT und der Funkergruppe DL0TUH eine Pagerinfrastruktur, die in Zukunft die Einsatzkräfte des CERTs alarmieren soll. Um diese zu erpoben, würden wir uns über viele Testaussendungen von euch freuen!
