This talk will demonstrate what everyone has long feared but never proven: there are hardware backdoors in some x86 processors, and they're buried deeper than we ever imagined possible. While this research specifically examines a third-party processor, we use this as a stepping stone to explore the feasibility of more widespread hardware backdoors.

OMG, this is pure geek porn, with consequences :D
Note that this is in Via x86, not Intel or AMD… but still research that we need… if only the designers could actually tell the researchers how stuff works, would be so much easier.
