VBootkit vs. Bitlocker in TPM mode

  • Article

One of the guys in our group, Robert Hensing has an interesting post about VBootkit and whether BitLocker in TPM offers any defense. Short answer: yes, it does. Slightly longer answer: The BitLocker guys anticiated this attack and the really long answer is in his post.

Chalk up another one for Vista :)

    Of course, what happens after that is that the BitLocker system goes into "recovery", meaning that it asks you to provide the recovery key. How many organisations have a plan to inspect a machine to see if it's had its MBR overwritten before they will provide the recovery key? How many organisations, faced with a panicked CEO, about to give a speech to a crowd, who sees a "please provide the recovery key" prompt, will tell the CEO to bring the machine in for checking?
