How do you scale up victim notifications from a couple of hundreds, to thousands, to millions to billions of stolen credentials? Credential theft is on the rise. Cybercriminals are gettings smarter and more efficient. Why hack in, if you can log in? At the DIVD we see this trend in the cases where we assist with notifying victims of credential theft. Where our first such cases started with a mere threehundred-something credentials we are now sometimes faced with credential dumps that contains

2025/08/12

This is NOT an introductory talk about ISMS (Information-Security-Management)! It is about my experiences and reflections about real-life issues when deploying an ISMS. There will be a section dedicated to 'hacking' an ISMS, though. The presumed audiences are: - individuals working in the realm of IS-/IT-security management - hackers working in environments that expose them to ISMS-related TODOs (I'll try to put these things into context!) - anyone trying to understand this

Time Lord's adventures: abusing time on Linux systems...

Chaos Computer Club - recent events feed ·

2025/08/12

What happens when an attacker controls time on a Linux system? This talk looks at how system clocks work, and what breaks when they’re manipulated. From bypassing delays to triggering subtle logic errors, we’ll explore how unstable time can subvert assumptions, break security controls, and cause software to behave in unexpected or unsafe ways. This talk explores the consequences of full control over time on a Linux system. We’ll start with a brief overview of how system clocks work, highlighting

Wikipedia tells us that _low-background steel_ is steel produced before the detonation of the first nuclear bombs. Yep, you guessed it, **this is a talk about Large Language Models**. LLM outputs have quickly spread like radionuclides, threatening everything from the scientific record to the existence of the Internet as we know it. In this talk I'll discuss _practical small web approaches_ that we can use to build a new Internet that doesn't suck quite so badly. There will also be memes ;-) Have

A team of Dutch scientist and cloud engineers is working on Ecofed: European Cloud Services in an Open Federated Ecosystem. The objective and scope of the ECOFED project are to develop a technical framework for a more open and integrated cloud usage model. This framework will enable multiple clouds from various providers to function as a single, cohesive system, offering a European alternative to hyperscaler clouds. In this open cloud ecosystem, users can easily switch between different
