Von wegen Eisblumen! Wie man mit Code, Satelliten und Schiffsexpeditionen die bunte Welt des arktischen Phytoplanktons sichtbar macht (39c3) Video 29.12.2025 37:31
Die Arktis ist eine Region, in der die Sonne monatelang weg ist, dickes Meereis den Weg versperrt und deshalb Forschungsdaten ziemlich rar sind. Kompliziert also, herauszufinden was im Wasser blüht! Mit einer Kombination aus Satellitenbildern, Expeditionen und Modellsimulationen auf Hochleistungsrechnern versuche ich, das Verborgene sichtbar zu machen: die faszinierende, farbenfrohe Welt des arkti...
APT Down and the mystery of the burning data centers (39c3) Video 29.12.2025 58:42
In August 2025 Phrack published the dump of an APT member's workstation. It was full of exploits and loot from government networks, cell carriers and telcos. The dump sparked a government investigation, and corpos like LG and Korea Telecom were asked to explain themselves. Hours before an onsite audit, the data center mysteriously caught fire, destroying almost a hundred servers. Then another data...
Och Menno X Disconnected Unexpected : Elbonian Incident Response : Wie reagiere ich falsch (39c3) Video 29.12.2025 1:22:42
Jeder redet darüber wie man eine Krise optimal bearbeitet. Bei Disconnected Unexpected geht es ja darum das das Publikum ein Szenario in den Raum wirft und Teams versuchen eine optimale Lösung zu finden. Bei Och Menno geht es darum das Sachen schief gehen. In der großen Nation Elbonien geht es darum das immer die komplizierteste, gerechtfertigte Lösung findet die garantiert die schlechteste Auswir...
There is NO WAY we ended up getting arrested for this (Malta edition) (39c3) Video 29.12.2025 54:36
3 years ago, 3 Maltese students were arrested and charged with computer misuse after disclosing a vulnerability to a local company that developed a mobile app for students. Through persistent media pressure, the students managed to obtain a presidential pardon to drop the case and funding for their lawyers. However, through this journey, there were mentions of punishment for retaliating through me...
Omnibus Halbgarer Machenschaften (OHM #23) (39c3) Video 29.12.2025 46:06
erdgeist & monoxyd denken laut. Aufgrund des großen Erfolgs soll das jetzt auch beim Congress versucht werden. Themen? Ja! Wahrscheinlich irgendwas mit so... Dingen, die gerade passiert sind und zu denen mal was gesagt werden muss. Besser wir als Lanz & Precht! Es gibt außerdem einen besonderen Anlass: 23! (Wo kommt das eigentlich her?)

Making the Magic Leap past NVIDIA's secure bootchain and breaking some Tesla Autopilots along the way (39c3) Video 29.12.2025 57:56
The Tegra X2 is an SoC used in devices such as the Magic Leap One, and Tesla's Autopilot 2 & 2.5 promising a secure bootchain. But how secure really is the secure boot? In this talk I go over how I went from a secured Magic Leap One headset, to exploiting the bootloader over USB, to doing fault injection to dump the BootROM, to finding and exploiting an unpatchable vulnerability in the BootROM's U...
Supplements und Social Media – wenn der Online-Hype zur realen Gesundheitsgefahr wird (39c3) Video 29.12.2025 58:32
Nicht zuletzt durch die Werbung in den sozialen Medien werden in Deutschland immer mehr Nahrungsergänzungsmittel verkauft. Einige Influencer bringen sogar ihre eigenen Präparate auf den Markt. Gleichzeitig häufen sich Fälle, in denen die Einnahme von vermeintlich harmlosen „Supplements“ zu Gesundheitsschäden geführt hat. Der Vortrag will daher die Mechanismen hinter dem Supplement-Hype aufzeigen,...
Programmierte Kriegsverbrechen? (39c3) Video 29.12.2025 1:00:09
Die automatisierten Zielsysteme des israelischen Militärs zeigen gut, wie KI-baserte Kriegsautomatisierung aktuell aussieht, was daran falsch läuft und warum wir Techies uns einmischen müssen Das Thema „KI in der Militärtechnik“ und die Beziehung zwischen Mensch und Maschine ist seit Jahrzehnten ein Thema in der Friedensbewegung, der Konfliktforschung, der Philosophie, den Sozialwissenschaften und...
Learning from South Korean Telco Breaches (39c3) Video 29.12.2025 49:14
2025 was a bad year for South Korean mobile network operators. All three operators (SK Telecom, KT, LG U+) were affected by breach in some part of their respective network: HSS of SK Telecom, femtocells of KT. Meanwhile, handling of the breach by each operators and post-mortem analysis of each breaches have stark differences. The technical details and implemented mitigations are often buried under...
Wer hat Angst vor dem Neutralitätsgebot? (39c3) Video 29.12.2025 42:01
Wer überhaupt „neutral“ sein muss, was das bedeutet, und wer sich jetzt wehren muss. „Neutralität“ wird zum neuen Kampfbegriff: Weil sie gegen die menschenfeindliche Politik von Friedrich Merz protestieren, wirft die CDU Gruppen wie Omas gegen Rechts, Greenpeace und Correctiv vor, nicht neutral zu sein. Unter Berufung auf ein angeblich verletztes Neutralitätsgebot werden staatliche Förderungen ges...
Shit for Future: turning human shit into a climate solution (39c3) Video 29.12.2025 40:06
Humanity has already crossed the point where simply reducing emissions will no longer be enough to keep global warming below 2°C. According to the IPCC (AR6, WGIII), it is now essential to actively remove greenhouse gases from the atmosphere in order to meet global climate targets, maintain net-zero (or even net-negative emissions), and address the burden of historical emissions. At the same time,...
When 8 Bits is Overkill: Making Blinkenlights with a 1-bit CPU (39c3) Video 29.12.2025 31:26
Over the last half year I have explored the Motorola mc14500 - a CPU with a true one-bit architecture - and made it simulate Conway's Game of Life. This talk gives a look into how implementing a design for such a simplistic CPU can work, and how it's possible to address 256 LEDs and half a kiloword of memory with just four bits of address space. In the late seventies, Motorola created a very cheap...
Watch Your Kids: Inside a Children's Smartwatch (39c3) Video 29.12.2025 36:44
Join us as we hack at a popular children's smartwatch and expose the secrets of every fifth child in Norway, their parents, and millions more. Smartwatches for children have entered the mainstream: Advertised on the subway and sold by your cell provider, manufacturers are charging premium prices comparable to an entry-level Apple watch. In exchange, parents are promised peace of mind: A safe, gent...
Zellkultur (39c3) Video 29.12.2025 45:13
Ich bin ja glaube ich reichlich spät, aber da Moepern endlich wieder zum Congress kommt und ich das erst vor kurzem erfahren habe, dachte ich, ich werfe unseren Namen mal in den Hut. Wir sind/waren ein Biologie-Podcast und durch Babypause bei Moepern ist der etwas eingeschlafen. Schaffen wir ein Revival? Verratet ihr's uns. Wir nehmen auch den Podcast-Tisch wenns sonst nicht passt. :) In der Zellk...
BE Modded: Exploring and hacking the Vital Bracelet ecosystem (39c3) Video 29.12.2025 34:57
The Vital Bracelet series is an ecosystem of interactive fitness toys, content on memory chips, and apps that talk via NFC. In this talk, we'll explore the hardware and software of the series, from its obscure CPU architecture, to how it interacts with the outside world, from dumping OTP ROMs and breaking security, to making custom firmware. The Vital Bracelet series, active from 2021 to 2024, was...
Teckids – eine verstehbare (digitale) Welt (39c3) Video 29.12.2025 29:53
Die Teckids-Gemeinschaft bringt Kinder, Jugendliche und Erwachsene zusammen, um gemeinsam aktiv für eine verstehbare (digitale) Welt zu sein. Bei Teckids geht es nicht "nur" um Technikbasteln und Programmieren mit Kindern, sondern darum, mit anderen, für andere, bei Events und gesellschaftlich aktiv zu werden. In letzter Zeit haben wir viele Projekte dafür unternommen. Unter anderem haben wir den...
What Makes Bike-Sharing Work? (39c3) Video 29.12.2025 40:23
Bike- and e-bike-sharing promise sustainable, equitable mobility - but what makes these systems successful? Despite hundreds of cities operating thousands of shared bikes, trip data is rarely public. To address this, we built a geospatial analysis pipeline that reconstructs trip data from publicly accessible system status feeds. Using this method, we gathered **43 million km** of bike-sharing trip...
a media-almost-archaeology on data that is too dirty for "AI" (39c3) Video 29.12.2025 37:55
when datasets are scaled up to the volume of (partial) internet, together with the idea that scale will average out the noise, large dataset builders came up with a human-not-in-the-loop, cheaper-than-cheap-labor method to clean the datasets: heuristic filtering. Heuristics in this context are basically a set of rules came up by the engineers with their imagination and estimation to work best for...
Celestial navigation with very little math (39c3) Video 29.12.2025 36:38
Learn how to find your position using a sextant and a custom slide rule, almost no math required! Since the dawn of time people have asked themselves: where am I and why am I here? This talk won't help you answer the why question, but it will discuss how determine the where in the pre-GPS age of sextants, slide rules and stopwatches by taking the noon sight, aka the meridian passage. The usual way...
Hacking Karlsruhe - 10 years later (39c3) Video 29.12.2025 40:19
"Wir gehen nach Karlsruhe!“ – das klang vor zehn Jahren nach Aufbruch und juristischem Hack. Heute ist klar: Strategische Prozessführung ist kein Sprint, sondern ein zähes, manchmal frustrierendes Dauerprojekt. In diesem Talk ziehen wir Bilanz: Was haben wir mit zivilgesellschaftlichen Verfassungsbeschwerden im Bereich Technologie erreicht – und wo sind wir gescheitert? Welche Fehler würden wir he...
Lightning Talks - Tag 3 (39c3) Video 29.12.2025 1:59:05

The Museum of Care: Open-Source Survival Kit Collection (39c3) Video 29.12.2025 37:43
The talk is about the ideas behind setting up the David Graeber Institute and the Museum of Care. The Survival Kit Collection brings together collectives developing open source "social technologies" —spirulina farms, self-replicating 3D printers, modular housing, low-cost water systems, and ... art and education. In 2019, together with David Graeber, we held the first workshop about the Museum of...
Design for 3D-Printing (39c3) Video 29.12.2025 37:35
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 a...
Greenhouse Gas Emission Data (39c3) Video 29.12.2025 39:04
Data about greenhouse gas emissions, both from countries and individual factories, is often publicly available. However, the data sources are often not as accessible and reliable as they should be. EU emission databases contain obvious flaws, and nobody wants to be responsible. Which factory in my city is the largest emitter of CO2? Which industrial sector is responsible for the largest share of a...
FAFO: How we stopped worrying and bought an Electron Microscope (39c3) Video 29.12.2025 1:01:36
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. -- This video was independently recorded & produced by dmi about this event: https://events.ccc.de/congress/2025/hub/e...
