'''TrueCrypt''' is an open source program to create and mount virtual encrypted disks in [[Windows|Windows Vista/XP/2000]] and [[Linux]] and [[Mac OS X|OS X]] as well as [[Whole Disk Encryption]] on Windows. It provides two levels of plausible deniability (hidden values / no signatures to make a distinction from random data), on the fly encryption and supports various encryption algorithms ([[AES|AES-256]], [[Serpent]] and [[Twofish]]).  As of version 6.0 TrueCrypt now supports hidden Operating Systems (Windows only).

If you encounter a system that has a mounted TrueCrypt drive, it is imperative that you capture the contents of the encrypted drive before shutting down the system. Once the system is shutdown, the contents will be inaccessible unless you have the proper encryption key generated by a user's password. You may also need an additional datafile.

The only option for acquiring the content of a dismounted TrueCrypt drive is to do a brute-force password guessing attack. [[AccessData|AccessData's]] [[Password Recovery Toolkit]] and Distributed Network Attack ([[DNA]]) can both perform such an attack, but DNA is faster.

TrueCrypt also supports keyfiles (it uses the first 1024 kilobytes of any file, but can also use it's PRNG to generate such keys). It is important to look for anything that might be used as a keyfile (such as a 1024k file on a USB stick).

When a hidden volume is mounted, the operating system and third-party applications may write to non-hidden volumes information about the data stored in the hidden volume (e.g. filenames). It is important to look for such kind of information.

Previous versions of encrypted containers may be found in the journaling filesystems. It is important to track any changes within the free space of the outer container to detect presence of a hidden container.

Hidden operating system is a system that is installed in a hidden TrueCrypt volume.

It is possible to detect network-enabled hidden operating systems by matching downloaded content (from network dump) with data on possible decoy system.

Investigator can also detect boot times by searching network dumps for IP packets with low IDs (only if Windows system is permanently connected to a LAN) and [[TCP timestamps]].

The Defense Cyber Crime Center, or DC3, is a Department of Defense organization run by the Air Force Office of Special Investigations. The center consists of three divisions:

Events

The DC3 sponsors an annual conference, the DoD Cybercrime Conference. The last conference was held in January 2007 in St. Louis, MO.

In 2006 the DC3 ran a Digital Forensics Challenge. At the 2007 DoD Cybercrime conference, the DC3 announced plans to make the challenge an annual event.

History

The DC3 was formed in 2001 when the newly created DCCI was merged with the existing DCFL and DCITA (at the time called the Defense Computer Investigations Training Program (DCITP).
