Today as well as yesterday’s 22C3 included tons of fun hacker stuff. Highlights from day 00 as well as 01 included a slew of topics from politics to hardcore geekery. We explored the CCC‘s annual hackfest to bring you the very best of the new hacks.

We commence our trip with Hack-A-Day’s buddy Dan “I like huge Graphs as well as I Cannot Lie” Kaminsky. Dan provided yummy OpenGL graphics as well as DNS cache proof of the Sony Rootkit around the world. He likewise released Xovi, a tool which enables you to do network visualizations in realtime. Realtime: we dig it.

Next on to fun scanning of 3G wireless networks! The team of btk as well as ahzf provided a rather comprehensive introduction to GPRS/UMTS packet theory (we utilize the term theory rather concretely right here since packet loss as well as lag are rampant on cellphone based data networks around the world). Slides for the talk in PDF style are here. They showed exactly how to circumvent packet filtering / port filtering / data type filtering on data networks. This can be incredibly helpful when trying to run VoIP applications over a cellphone network because they are typically blocked.

Also of note was the talk on IrDA hotel system hacking provided by major Malfunction. Which we discussed when we were at Toorcon.
