What does it take to build a fully functional (and actually usable) voice assistant that runs on a Raspberry with FOSS? This talk describes the journey from the idea to Version 1.0 (and beyond). It has to be a HAL9000 - the enclosure for my cloud-free digital voice assistant. The personal project is based on FOSS and runs on a Raspberry Pi Zero2 W in combination with a RP2040 (with a small display...

Schon wieder muss Karlsruhe ran Vor mehr als zehn Jahren lang ein Staatstrojaner auf dem Seziertisch des CCC. Was die Analyse zeigte, waren neben eklatanten handwerklichen Fehlern auch die mangelnde Prüfbarkeit der Schadsoftware und weitere grundsätzliche Probleme solcher Ausspähmethoden. Leider hat sich nicht viel verbessert – im Gegenteil. Und so haben wir im Juli dieses Jahres eine weitere Stel...

The role of the Internet in the Ukrainian war is not been fully considered yet. Currently, primary Internet based attacks are analyzed, but it is greatly neglected that with the help of the Internet measurement verifiable statements can be made about the real world. Through global Internet scans and a passive blackhole sensor network, we can identify digital and conventional attacks and their effe...

Was hat sich beim Thema Digitale Gewalt seit dem letzten Camp verändert? Warum plant das BMJ eine Digitale-Gewalt-Gesetz, das diejenigen identifizieren und bestrafen soll, die in Messengern über schlechte Restaurants lästern, und warum ändert sich noch immer nichts an der Pflicht zur Adresse im Impressum? Das und mehr im Update zum Stand der Dinge bei der Digitalen Gewalt. Vier Jahre nach ["Was tu...

In diesem Vortrag wollen wir euch einen Überblick geben über die digitale Sicherheitssituation von Journalismus weltweit. Spoiler: nicht so gut, und eher schlechte Aussichten. Außerdem erzählen wir ein bisschen was das Digital Security Lab bei Reporter ohne Grenzen anbietet, was wir tun und wie man Betroffene am besten an uns verweisen kann. about this event: https://pretalx.c3voc.de/camp2023/talk...

We'll take a look at how DJI - dominating player for commercial and recreational drones - builds their software, specifically from a security angle. This talk will discuss DJI drones, most specifically the DJI Mini-series; looking at the hardware, discussing attack angles, up to a full compromise of a current drone for custom firmware purposes. Along the way, we'll look at a lot of security WTFs t...

We‘re c3stoc - the CCC sticker operation center. After helping with the sticker distribution at 36c3 we had to find a solution to ensure new laptops wouldn‘t remain naked during the pandemic. During the last three years we organized remote sticker exchanges. Now it‘s time to share our learnings about exchanges and stickers! The idea was just to make sure CCC Congress doesn’t have one single sticke...

We will talk about the lately published Denail of Service attack abusing the Service Location Protocol. The research has shown that there are still protocols lurking in the dark to be explored and ab/used. The focus will be on basics of DoS attacks, then focus on SLP, the impact, defense mechanisms as well as the global attack surface. Furthermore, there will be some goodies in regard of other use...

Hidden inside basically every physical machine that needs precise control, PID loops are running the show. Quadcopters, self-balancing robots, and even the hot end of your 3D printer all use the same simple routines. Knowing how they work, deep down, and how to set their mystical three parameters is part art and part science, but it's nothing you can't pick up in a quick talk. Nothing explains com...

Blockchain bugs present unique challenges for developers and security testers. Draw...

## How can artificial intelligence support penetration testing? Most processes in for the penetration-testing cycle require detailed knowledge, time and human resources. While the are sophisticated scripts for the reconnaissance and various exploits, creating a detailed plan of the attack path can be complicated and laborious. The use of an enforcement learning algorithm can help penetration-testi...
