Update: I have now also been accepted for BSidesLV, which means you have two chances to see this presentation if you're in Vegas for Defcon.
BSides: 6-7PM Thursday, 7/26, Artisan Hotel
Skytalks: 3-4PM Friday, 7/27, Rio Hotel in Skytalks room (location TBD)
The presentation will focus on the new, faster techniques I developed earlier this year, which have not been written into my tutorial yet. If you can't make either talk, I plan to update the tutorial some time in August.
