(Source: BitLocker: Use BitLocker Drive Encryption Tools to manage BitLocker). You can determine the types of protectors enabled for a given BitLocker volume by executing the following command while the volume is mounted:

Let us check which key protectors exist, how they are used, and how to approach the attack of a BitLocker volume protected with a given protector type. As a result, in order to unlock the volume and decrypt the data, you will need either the original piece of hardware (and possibly other credentials) the brute force attack will not be feasible. With some of these protectors, the protection is hardware bound. BitLocker Protector TypesīitLocker volumes (or, rather, the volume master keys) can be protected with various methods called protectors. By creating a memory dump and extracting the VMK from that dump with Elcomsoft Forensic Disk Decryptor, experts can instantly mount or quickly decrypt the content of the volume regardless of the type of protector used. While the BitLocker volume is mounted, the volume master key (VMK) resides in the computer’s RAM. The thing is, it would not be possible to access the encrypted data if the appropriate encryption key was not stored in the computer’s volatile memory (RAM). The volume master key is encrypted by the appropriate key protector and also stored in the encrypted drive.

Where are all of these keys stored? The full volume encryption key (FVEK) is encrypted by the volume master key (VMK) and stored in the encrypted drive. When changing a key protector, a new VMK will be created and used to encrypt the old FVEK with the new VMK. The use of intermediate key (VMK between FVEK and any key protectors) allows changing the keys without the need to re-encrypt the raw data in a case a given key protector is compromised or changed. The volume master key is in turn encrypted by one of several possible methods depending on the chosen authentication type (that is, key protectors or TPM) and recovery scenarios.ĭoes the VMK in this scheme looks redundant? It has its purpose.
Let’s dig into more details about the various encryption keys used by BitLocker to protect your data and the encryption key.īitLocker implements staged protection and employs multiple keys, each serving its own purpose.Īccording to Microsoft, raw data is encrypted with the full volume encryption key (FVEK), which is then encrypted with the volume master key (VMK). The Introduction to BitLocker: Protecting Your System Disk describes how BitLocker works from the user’s perspective. Learn how to approach BitLocker volumes depending on the type of protector.

Attacking the password is only possible in one of these cases, while other protectors require a very different set of attacks. BitLocker volumes may be protected with one or more protectors such as the hardware-bound TPM, user-selectable password, USB key, or combination thereof. BitLocker is well-studied and extensively documented solution with few known vulnerabilities and a limited number of possible vectors of attack. Run xauth list command to check authentication cookie.BitLocker is one of the most advanced and most commonly used volume encryption solutions. (gedit:20511): Gtk-WARNING **: cannot open display: :0
