22C3 Day 00 and 01 Round Up

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.

    Those are neat visualizations, and using SDL to boot. I can only assume that they animate. Hopefully videos of the talk will come out soon.

    So I get the prog to run, with like 485 of my endpoints in it. However, basically all that happens is the red lines and dots expand away from eachother than fade.
    Is there some type of text doc with a bit more instructions than the defualt help in the prog? I’m thinking I don’t have my file setup properly. basically I just listed all the ips. Any help is appreciated.

    I love the IRDA stuff. I just got a Fossil Wrist PDA, and I’m thinking I need to get the Palm and Fossil SDKs and get to work.
