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.

24C3: Mifare Security

hosh — Sun, 06 Jan 2008 15:41:40 +0000

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!

24C3: Bluetooth Stuff

hosh — Fri, 28 Dec 2007 21:06:50 +0000

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

Camp 2007 Review

hosh — Sun, 26 Aug 2007 14:42:28 +0000

Camp is over. Unfortunately I did not have enough spare time to write a in depth review, but I can say it was a lot of fun and very interesting. I didn’t enjoy the lectures very much, because the acoustic was lousy and the content of the lectures was not as good as I expected. But the concept of villages with people of same interests was very good. That way it was very easy to meet people with the same interests. One very interesting lecture was about the A5 Cracking Project. The projects goal is to implement a practical attack on the A5 cipher used in GSM networks. The cipher has already been broken in 1998 after the specs leaked into public because someone forgot to sign a NDA. But until now there is no public implementation of the attacks. There is a Wiki where the project is coordinated, check it out. That stuff is at the very top of my agenda. hmm, maybe not at the very top, but at the top .

Anyway, due to the great atmosphere at the camp (especially during the night), I enjoyed it very much. Check out the flickr slideshow. I also made some photos, mostly night shots:

Chaos Communication Camp 2007

hosh — Wed, 18 Jul 2007 21:10:24 +0000

This summer I am going to visit the Chaos Communication Camp in Finowfurt near Berlin, Germany (Old Europe). Two years ago i visited a similar camp: What The Hack. I hope the Camp this year will as much fun as WTH, or even more (actually I am pretty sure.).

Besides the many interesting people you can meet there, there are some pretty interesting lectures, too. Just have a look at the Fahrplan.
There will be some WEP-Hacking by Eric, some Fun with NFC Mobile Phones and some other RFID Stuff 1, 2, some oLd 5cHO0l h@cK1n9 and many other interesting things…

I would love to meet some of the visitors and commenter of this blog. As usual there will be a huge phone-network on the campsite, feel free to contact me via eventphone’s DECT-Network: 4674

Happy hacking out there, see you soon!
