Re: TruCrypt users
I do recall in 2009 a bootkit was developed called Stoned which could successfully bypass TrueCrypt. Stoned injects itself into the MBR, a record which remains unencrypted even if the hard disk itself is fully encrypted. During startup, the BIOS first calls the bootkit, which in turn starts the TrueCrypt boot loader. Stoned uses a "double forward" to redirect I/O interrupt 13h, which allows it to insert itself between the Windows calls and TrueCrypt.

I would like to point out that this attack DOES require either physical access to the PC with the user already logged in with admin rights or an end user must be enticed to execute the malware. This DOES NOT actually break the encryption but rather acts as a MITM attack.

TrueCrypt is simply not designed to handle this method of attack.

This method could be applied to other software based encryption such as BitLocker and PGP.

Another flaw is that TrueCrypt stores it's keys in RAM and has been confirmed to be vulnerable to a Cold Boot Attack. This is where the booted machine is powered off and the RAM modules are quickly frozen and the keys can be extracted.

Again, this method requires physical access to the machine that is powered on or suspended.

In conclusion, as long as the attacker has physical or administrative access to the system, software based encryption will never work.

Anyone out there left high and dry by this? I'd love to hear some firsthand experience with the tool and what users plans are next.
