33c3 Talks – What could possibly go wrong with “insert x86 instruction here” ?

This was one of the few technical talks at 33c3 I managed to see, by that I mean live-stream during an access control shift, by Clémentine Maurice and Moritz Lipp.

The talk gave an overview of some already known possible information leaks by abusing certain x86 instructions(the same concept applies to ARM too though) and demonstrating the various ways an attacker could use them.

White Paper on Incident Handling First Steps, Preparation Plans, and Process Models

We just published my Whitepaper about First Steps, Preparation Plans, and Process Models for Incident Handling, that I wrote to pass the time between Christmas and New Year. The whitepaper sums up information that I consider to be useful to prepare for IT security incidents as a conclusion from the incidents in which we supported over the past year.

ERNW at 33C3 – Part 1

This is part 1 of our report series on interesting talks of the 33rd Congress of the Chaos Computer Club. Every year the congress attracts hundreds (up to twelve thousand this year) of technical interested people with the opportunity to socialize and exchange knowledge with each other. The congress is organized by the European largest hacker association and speakers give talks about technical and societal issues like surveillance, privacy, freedom of information, data security and various more.

Talks in this part deal with CCC at schools, Wi-Fi security and the security of the N26 banking app.

First dedicated Forensic Computing Training at TR17

I am looking forward to our newly introduced dedicated Forensic Computing Training at TR17!
We will start the first day with a detailed background briefing about Forensic Computing as a Forensic Science, Digital Evidence, and the Chain of Custody. The rest of the workshop we will follow the Order of Volatility starting with the analysis of persistent storage using file system internals and carving, as well as RAID reassembly with lots of hands-on case studies using open source tools. As a next step, we will smell the smoking gun in live forensics exercises. Depending on your preferences we will then dig a bit into memory forensics and network forensics.

TR17 Training: Crypto attacks and defenses

This is a guest blog written by Jean-Philippe Aumasson & Philipp Jovanovic about their upcoming TROOPERS17 training: Crypto attacks and defenses. 

The 1-day training from last TROOPERS has become a 2-day training, featuring even more real-world attacks and defenses as well as new hands-on sessions! We’ll teach you, step by step, how to spot and exploit crypto vulnerabilities, how to use the strongest forms of state-of-the-art cryptography to secure modern systems (like IoT or mobile applications), and bring you up to speed on the latest and greatest developments in the world of cryptography, such as TLS 1.3, blockchains, and post-quantum crypto.
