Free download Bitlocker brute-force cracking tool to unlock, open, break Bitlocker encrypted drive without the password or recovery key in Windows. The attack is broken into two distinct stages. BitLocker implements staged protection and employs multiple keys, each serving its own purpose. Readme License. 1 dictionary phrase. Important: You will be able to perform a password attack if and only if the BitLocker volume is protected with a password. No password is perfect, but taking these steps can go a long way toward security and peace of mind. In this mode, the TPM module will only release the encryption key if you correctly type the PIN code during pre-boot phase. Reset passwords to local Windows accounts and Microsoft Account and perform a wide range of administrative tasks. Select the volume you are about to extract hashes from. Attack vectors: Since this protector requires both the PIN code and the key file stored on a USB drive, you will be required to produce both to satisfy the TPM module and release the decrypted VMK. To open it, open the terminal and type “sqldict”. BitLocker volumes (or, rather, the volume master keys) can be protected with various methods called protectors. The tool automatically detects full disk encryption on all built-in and removable drives, and allows extracting encryption metadata that is required to brute-force the original password to encrypted disk volumes. The full volume encryption key (FVEK) is encrypted by the volume master key (VMK) and stored in the encrypted drive. A brute-force attack will be assigned. In other words, BitLocker passwords are extremely likely to be used on anything but the system volume. Brute force attacks became not just faster, but much smarter as well. BitCracker is the first open source password cracking tool for memory units encrypted with BitLocker (using the password authentication method). Elcomsoft Distributed Password Recovery offers zero-overhead scalability and supports GPU acceleration for faster recovery. HTTP password brute-force via GET or POST requests; Time delay between requests; Cookie fuzzing; 5. According to a report by Denis Andzakovic from Pulse Security, the researcher has found a new attack method that can compromise BitLocker encryption keys. Your system will boot to login prompt; the VMK will be decrypted with a storage root key (SRK) that is stored in the TPM (or Intel PTT) module and only releases if the system passes the Secure Boot check. It will open the following view. This option arguably offers the best balance between security and convenience, combining “something that you have” (the TPM module) with “something that you know” (the PIN code). Elcomsoft System Recovery will be launched once the boot sequence is complete.

This option requires both the TPM and a USB flash drive (or CCID smartcard) to be present in order for the system to boot. ), the availability of recovery information (BitLocker Recovery Key) or memory dump/hibernation file/page file, as well as whether you have the complete PC or just the disk/image. 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. Passware Company has introduced the first commercial software solution that offer a way to Crack files encrypted by BitLocker system. The user’s existing passwords are an excellent starting point. With some of these protectors, the protection is hardware bound. The RAM dump/hibernation file/page file attack. Attack vectors: Since TPM+PIN is an interactive mode, you will be required to produce the correct PIN, which then must be entered on the computer containing the TPM module. Bitcracker performs a dictionary attack, so you still need to create a list of possible recovery keys. (Source: BitLocker: Use BitLocker Drive Encryption Tools to manage BitLocker). Once you have finished dumping the encryption metadata, transfer the files to Elcomsoft Distributed Password Recovery to recover the original plain-text password. This tool was developed for that, for brute forcing BitLocker recovery key or user password. Elcomsoft System Recovery allows starting the investigation sooner by booting the computer from a portable flash drive with read-only access to computer’s storage devices. In the example below, we’re dealing with a physical device. Using processor data collected from Intel and John the Ripper benchmarks, we calculated keys per second (number of password keys attempted per second in a brute-force attack) of typical personal computers from 1982 to today. On another screenshot, Select the Run Wizard (Ctrl+W) as the shortcut. BitLocker is well-studied and extensively documented solution with few known vulnerabilities and a limited number of possible vectors of attack. BitLocker volumes may be protected with one or more protectors such as the hardware-bound TPM, user-selectable password, USB key, or combination thereof. At the same time, this option may not be convenient in multi-user environments. Open encryption metadata (the hash file) produced by either Elcomsoft Forensic Disk Decryptor or Elcomsoft System Recovery during the previous step. Aircrack-ng can be used for any NIC which supports raw monitoring mode. Attacking a BitLocker volume protected with a different type of protector would be a waste of time.
