Today and yesterday’s 22C3 included tons of fun hacker stuff. Highlights from day 00 and 01 included a slew of topics from politics to hardcore geekery. We toured the CCC‘s annual hackfest to bring you the best of the new hacks.
We commence our tour with Hack-A-Day’s friend Dan “I Like Big Graphs and I Cannot Lie” Kaminsky. Dan presented yummy OpenGL graphics and DNS cache proof of the Sony Rootkit around the world. He also released Xovi, a tool which allows you to do network visualizations in realtime. Realtime: we dig it.
Next on to fun scanning of 3G wireless networks! The team of btk and ahzf presented a rather thorough intro to GPRS/UMTS packet theory (we use the term theory rather concretely here because packet loss and lag are rampant on cellphone based data networks all over the world). Slides for the talk in PDF format are here. They showed how to circumvent packet filtering / port filtering / data type filtering on data networks. This can be extremely useful when trying to run VoIP applications over a cellphone network since they are usually blocked.
Also of note was the talk on IrDA hotel system hacking presented by Major Malfunction. Which we mentioned when we were at Toorcon.

Hack-A-Day is here at 22C3: Private Investigations, the Chaos Computer Club‘s annual hacker conference in snow covered Berlin, Germany. The CCC’s annual Congress is the European answer to Las Vegas located DEFCON. This 22nd annual conference has been lengthened from three days to four to be able to accommodate more talks.
We’ll be here all week reporting on the coolest hardware hack topics at the conference from talks to Blinkenlights. If you’re here, drop us a line in the comments!

The OSMC project was started in 1998 to provide a high quality H-bridge speed control to hobbyists and professionals. The original design was intended to be used by people who were building Battle Bots and other competition robots, but the line has expanded since then. The project embraces the open source spirit by making the plans freely available and encouraging modification. This is the same controller that Trevor Blackwell used in his Electric Unicycle.
