It’s been a long while since we made an update to one of our most technically advanced tools, Elcomsoft Forensic Disk Decryptor (EFDD). With this tool, one could extract data from an encrypted disk volume (FileVault 2, PGP, BitLocker or TrueCrypt) by utilizing the binary encryption key contained in the computer’s RAM. We could find and extract that key by analyzing the memory dump or hibernation files.

What Elcomsoft Forensic Disk Decryptor did not do until now was pretty much everything else. It couldn’t use plain text passwords to mount or decrypt encrypted volumes, and it didn’t support escrow (recovery) keys. It didn’t come with a memory imaging tool of its own, making its users rely on third-party solutions.

With today’s release, Elcomsoft Forensic Disk Decryptor gets back on its feets, including everything that was missing in earlier versions. Plain text passwords and recovery keys, a Microsoft-signed kernel-level RAM imaging tool, the highly anticipated portable version and support for the industry-standard EnCase .E01 and encrypted DMG images are now available. But that’s not everything! We completely revamped the way you use the tool by automatically identifying all available encrypted volumes, and providing detailed information about the encryption method used for each volume.


Investigators start seeing BitLocker encrypted volumes more and more often, yet computer users themselves may be genuinely unaware of the fact they’ve been encrypting their disk all along. How can you break into BitLocker encryption? Do you have to brute-force the password, or is there a quick hack to exploit?

We did our research, and are ready to share our findings. Due to the sheer amount of information, we had to break this publication into two parts. In today’s Part I, we’ll discuss the possibility of using a backdoor to hack our way into BitLocker. This publication will be followed by Part II, in which we’ll discuss brute-force possibilities if access to encrypted information through the backdoor is not available. (more…)

BitLocker is a popular full-disk encryption scheme employed in all versions of Windows (but not in every edition) since Windows Vista. BitLocker is used to protect stationary and removable volumes against outside attacks. Since Windows 8, BitLocker is activated by default on compatible devices if the administrative account logs in with Microsoft Account credentials. BitLocker protection is extremely robust, becoming a real roadblock for digital forensics.

Various forensic techniques exist allowing experts overcoming BitLocker protection. Capturing a memory dump of a computer while the encrypted volume is mounted is one of the most frequently used venues of attack. However, acquiring BitLocker-encrypted volumes may become significantly more difficult with the release of Windows 10 November Update. In this article, we’ll explore existing methods of recovering BitLocker volumes, look at what has changed with November Update, and review the remaining acquisition paths.
