I think we all know the fact that boot-harddrives can be encrypted.
Windows usually uses Bitlocker (relying on AES-CBC) and Linux / Unix usually uses dm-crypt (relying on AES-CBC) and the rest of the software usually uses XTS-mode (TrueCrypt, BestCrypt,…).
Now, there’s the potential for bitflip attacks with CBC.
My first thought was to use this for DoS, by simply flipping any bit of either the drive’s salt or of the log-in hashs. Would it be possible, by flipping a single bit (multiple bits), to deny access from any legitimate user?
The computer can be considered shut-down as of time of acquiration.
Are there any attacks, exploiting the bit-flipping property of CBC, to break the security of the targeted computer?
A security break can be a DoS, a placement of an exploit or similar.
