Truecrypt Broken in Minutes
Basically it involves the user leaving the TC drive open and putting the computer on standby. Then you simply plug in a firewire cable and fish around for the encryption key. Does Ubuntu allow this and what's being done about it? It would seem like a security vulnerability in itself if someone could plug a cord into your computer and get anything off of it, nevermind the password to a highly secured virtual hard-drive.
Which is more important in obtaining the truth, "what" or "why"? Trick question. They are of equal importance.
