I and most of the RSG are just doing the last preparations before leaving for Las Vegas tomorrow morning. It will be my first time at defcon and I'm also giving a talk so I'm pretty excited.
Also I am participating in the CTF (with the other people from the RSG) I'll still try to post from defcon at least once per day.
Finally don't forget to come to my talk Advanced Attacks Against PocketPC Phones since it will be very very cool. I'll post some more details (stuff the abstract doesn't tell you) tomorrow :-P
