[Cryptography] A bulletproof vest with moth holes

[Peter Gutmann]

Intel recently fixed a hardware-level vulnerability that allowed its Boot
Guard to be bypassed:

Unfortunately they've released no technical details on how they did this, but
what makes it interesting is that they appear to have modified the functioning
of the uber-secure can't-be-bypassed hardware-based security... with a
software patch.  Hmmm...
