The Last of Us - Fighting the EU Surveillance Law...

Chaos Computer Club - recent events feed ·

2025/12/29

The virus of surveillance is spreading across the European Union. In the form of its "ProtectEU" Internal Security Strategy, the European Commission is planning to attack encryption, re-introduce mandatory data retention and strengthen Europol and Frontex, the main agents of its oppressive law enforcement infrastructure. In this talk, we will journey the wastelands of the EU surveillance apocalypse together: We will take a close look at what politicians are planning to undermine our fundamental

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 arktischen Phytoplanktons. Im Arktischen Ozean wird immer deutlicher, wie stark die globale Erwärmung den

Gegenmacht - Best of Informationsfreiheit (39c3)

Chaos Computer Club - recent events feed ·

2025/12/29

Sind mehr Infos wirklich die Lösung? Ob Jens Spahn, Philipp Amthor oder Friedrich Merz - sie alle sagen offen, was sie vorhaben und machen keinen Hehl aus ihren Verbindungen zur Trump-Regierung, zu Milliardären und der fossilen Lobby. Was bringt Transparenz in Zeiten der autoritären Wende? Transparenz braucht Rechenschaft. Ohne Konsequenzen bleibt Transparenz wirkungslos. Wie können wir also eine wirksame Gegenmacht schaffen, die Veränderungen durchsetzt? Philipp Amthors Angriff aufs

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 media disclosure. The story has not concluded, and there will be no amendments to the Maltese computer

APT Down and the mystery of the burning data centers...

Chaos Computer Club - recent events feed ·

2025/12/29

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 center burned - and unfortunately, there was even one death. The talk aims to revisit this mysterious

Learning from South Korean Telco Breaches (39c3)

Chaos Computer Club - recent events feed ·

2025/12/29

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 the vague terms, and occasionally got lost in translation to English. In this talk, I will cover the

2025/12/29

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 USB recovery mode affecting all Tegra X2s. In mid 2024, a friend approached me about Magic Leap making

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 den kritischen Data & Algorithm Studies. Doch in den letzten Jahren wurden Waffensysteme mit

2025/12/29

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, zudem erklären, warum aktuell ein ausreichender Verbraucherschutz insbesondere im Internet nicht

Wer hat Angst vor dem Neutralitätsgebot? (39c3)

2025/12/29

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 gestrichen und NGOs geraten unter Beobachtung des Verfassungsschutzes. Julia Klöckner verbietet im Namen

2025/12/29

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, degraded soils and the climate crisis are a threat to global food security. Two years ago, I presented

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, gentle introduction into the world of technology — and a way to call, text, and locate their child at any

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 CPU, intended to replace logic circuits made from electromechanical relays. The resulting IC is so

What Makes Bike-Sharing Work? (39c3)

Chaos Computer Club - recent events feed ·

2025/12/29

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 trips across **268 European cities**. Combined with over **100 urban indicators** per city, our analyses

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 a line of toys that revolved around a number of fitness bracelets that encouraged exercise by raising

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 neuen Themen-Slot "Jung und überwacht" bei den BigBrotherAwards 2025 gestaltet und bereiten

2025/12/29

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 their perspective of “cleaning”. Most datasets use heuristics adopted from existing ones, then add some

"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 heute vermeiden, welche Wege waren richtig? Und was bedeutet es, wenn das höchste deutsche Gericht

Greenhouse Gas Emission Data (39c3)

Chaos Computer Club - recent events feed ·

2025/12/29

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 country's contribution to climate change? It should not be difficult to answer these questions. Public
