According to MeriNews an Indian information security start up has, allegedly, discovered a new vulnerability, which allows attackers to steal computer boot passwords and bypass the security of disk encryption.

Even hard-drive encryption does not help here”.
A more detailed reading of the technical paper shows the decryption is not simple, may not always be possible, and the “attacker” would have access to the files anyway:
For example the Truecrypt technical paper states that:
