Well, it's almost BlackHat time. Here are my picks so far for Day 1. As you can see, I still haven't narrowed it down completely.
11:15-12:30 Option 1: Dan Kaminsky, "DNS Goodness". On one hand, the DNS vulnerability is already public; on the other hand, the talk will probably still be interesting even if the 0day hype is missing. Option 2: Nate Lawson, "Highway to Hell: Hacking Toll Systems". My formal education and early work was in Electrical Engineering, so I'm always interested in hardware talks. I haven't touched a soldering iron in years so I have to live vicariously through people like Nate.
13:45-15:00 Option 1: Chris Hoff, "The Four Horsemen of the Virtualization Security Apocalypse". I haven't been paying enough attention to virtualization security and I think this talk will be quite informative. Option 2: Danny Quist and Colin Ames, "Temporal Reverse Engineering". Sounds like an interesting approach.
15:15-16:30 Option 1: Hovav Shacham, "Return-Oriented Programming: Exploits Without Code Injection". The topic sounds pretty straightforward conceptually but it will be interesting to see the implementation. Option 2: Tom Stracener and Robert Hansen, "Xploiting Google Gadgets: Gmalware and Beyond". Not expecting any huge revelations on this one but it's likely to be entertaining.
18:00-19:00 The Pwnie Awards. Turnout last year was kind of slim, but I bet the room will be full this year as it's been publicized more.
Day 2 picks coming soon!
