Breaking BitLocker Encryption: Brute Forcing the Backdoor (Part II)

Wednesday, July 27th, 2016


How often do you think forensic specialists have to deal with encrypted containers? Compared with office documents and archives that are relatively infrequent, every second case involves an encrypted container. It may vary, but these evaluations are based on a real survey conducted by our company.

It is hard to overestimate the importance of the topic. In the first part of our story we discussed the way of getting access to encrypted volumes using an encryption key. Now, let’s see which other ways can be used.

Unlike Elcomsoft Forensic Disk Decryptor, Elcomsoft Distributed Password Recovery does not search for existing decryption keys. Instead, it tries to unlock password-protected disks by attacking the password. The tool applies an impressive variety of techniques for attacking the password. In this case, the whole disk encryption scheme is only as strong as its password. Fortunately, the tool can execute a wide range of attacks including wordlist attack, combination attacks, mask attacks, smart attacks and so on and so forth, with advanced GPU acceleration and distributed processing on top of that. The whole sophisticated arsenal comes in particularly handy if we speak about more or less secure passwords.
