Toorcon was a really a wonderful experience. I met lots of readers and other interesting people in a very social environment. It’s really cheap and I would encourage you too attend next year.
I’ve posted the few photos I have to Flickr. While you are over there you might as well join the Hack-A-Day photo pool. Quinn’s photos are much better than mine; I didn’t have to haul around a Canon EOS D30 though. Pictures of me: one, two. The guys from EVDO-Coverage also have a photostream. They provided EVDO to hackers in need at the conference and will probably be sending me some fun hardware to play with.
I’ll be updating the posts with slides as soon as they get posted.
Once again: I’d like to thank the organizers, speakers, and Hack-A-Day readers for making the conference such a fun time. I hope to see everyone again at REcon, Shmoocon, and Toorcon next year.
That’s it for Toorcon coverage. Back to business as usual tomorrow.
Dan Kaminsky was wondering most of the weekend what I would post about Toorcon. If there’s one thing I learned it is this: Dan Kaminsky is nuts. The future projects and other theory that comes out of his mouth is awesome. I had a great time hanging out with him. His talk was similar to the one from this year’s Blackhat (slides here).
He also covered fragmentation attacks to bypass IDS, his massive scanning project and visualizing the resulting data.

Major Malfunction’s infrared hacking is considered a “must-see” talk. His interest in IR was piqued when he bought a new car and could no longer replay the IR remote code with his Palm III to unlock the doors. So he started investigating rolling code remotes and other IR based devices. Modern hotels usually have the room services system built into the tv. Maintenance and house keeping can use specialized remotes to perform administrative functions. There is no security so you just need to find the specialized codes. He read one code and found out it was 14bits. It would take nine hours to check all possible codes by hand. Of course not all 16,384 possible codes do something. Major took the “ON” code, started flipping bits and testing to see if the code still worked. If it still works it means the bit is ignored. It turned out that only 10bits were actually being used. Testing that many codes only takes 35 minutes. Once completed you can do things like modifying your room bill or someone else’s even view all of the pay-per-view movies. The “read” link goes to a recent Wired interview.

Sysmin & QuiGon of the Hacker Pimps presented their new FairuzaWRT firmware for the WRT54GS. They started with the OpenWRT firmware and added packages to make it useful as a penetration tester. Tools were added to mount NFS and Windows shares. Several exploits are included as well. The FairuzaUS shell script ties everything together by providing a simple frontend for changing NVRAM settings and launching the attack tools.

This was probably my favorite talk at the conference and I hadn’t even planned on going till someone pointed out what bunnie’s previous work was. There are a couple reasons why bunnie enjoys reverse engineering silicon: It is constrained by physics, silicon is hard enough to design before thinking about security, and the chips have to be reverse engineered during the production process. He has a really interesting example on his blog of how he hacked the PIC18F1320 which will give you a good overview of the process.

Apparently when Jason Spence isn’t reading Hack-A-Day he is reading manufacturer data sheets. He’s fun in real life; I swear. The talk started with an overview of motherboard architecture. By studying manufacturer data sheets you can figure out a pathway to attack the BIOS. A proof of concept BIOS backdoor has already been developed. This is a very scary situation since the OS isn’t even loaded yet and will be completely blind once it is up. Jason pointed out that smaller manufactures (VIA, SIS) don’t publish data sheets fearing patent infringement. This lack of information makes security a lot harder to pull off. Jason says he’ll be contributing a couple articles in the future.
UPDATE: Jason has posted his uncensored slides.
