Subject: RE: [Full-disclosure] Firewire Attack on Windows Vista

The main point is to grab encryption keys from memory where the drive is
encrypted - but that has to be while the device is on.  I mean, it
doesn't really matter if you disable password auth when you have
physical access as you can just take the drive out, boot from CD, etc...
