During the upcoming weekend (17.07. – 19.07.2009) the Chaos BBQ Weekend will take place in Dortmund, Germany, old Europe (N51°31’39.4″ E7°27’53.8″). There will be some Workshops and Lectures and of course there will be a lot of meat (vegi food as well).
In case you need a place for sleeping, don’t worry there will be room for everyone!

See you next weekend!

Hi there, it is getting time for the annual Chaos Communication Congress in Berlin, Germany, Old Europe. This time there are many speeches about mobile device security and GSM networks, check out the “Fahrplan”.
I hope to meet some old friends and find some interesting new people. And by the way: Happy Christmas!

This weekend the CBBQWE08 will take place in Dortmund, Germany, Old Europe. It’s organized by the CCC Dortmund there will be some lectures – I will give an overview of the new security features of Bluetooth Secure Simple Pairing – but the main focus of the event is the BBQ and having some fun. I hope it will be good weather.

Seems that I have missed one of the most interesting speeches at 24C3.
Henryk Plötz and Karsten Nohl presented the recent developments in reverse engineering the Mifare RFID card. What they basically did is polishing away the different layers of the chip in the Mifare card and then visually analyze the layers, trying to find the cryptographic relevant parts. The security of the low-end Mifare Classic cards is to be concerned as broken. “Start migrating!” 😉 This does not have an impact on the high-end Mifare DESFire card. Check out the video!

Hi there! Greetings from 24C3, the annual hacker meeting of CCC. Some updates on Bluetooth related stuff:

Balle released a new version of bluediving, now available in version 0.9.

A funky new tool has been released at this congress: bluedrift. What driftnet is for ethernet, bluedrift is for Bluetooth. Using a special Bluetooth dongle which is capable of being flashed, you are now able to automatically sniff Bluetooth traffic and extract OBEX data, e.g. electronic vcards or pictures, from your sniff.

Another project I didn’t know before is the Wave Bubble by ladyada: “A design for a self-tuning portable RF jammer”

Best cite of the congress: “MIT doesn’t teach you how to fuck GSM-Networks” — Ladyada
