Application and Source

Help

An application for performing a dictionary attack on encrypted volumes. Basically a wrapper around FreeOTFE, which also supports Linux volumes (Cryptoloop, dm-crypt, LUKS).

By design these encrpytion systems are very slow to brute force, so a dictionary based attack is only appropriate for poorly chosen passphrases.

Benefits

  • Check if your passphrase is secure

How it works

  • Count the initial number of drives in the system
  • Loop through the input in the dictionary
    • Execute a command line statement to mount the encrypted image using the current passphrase (/mount /volume volume /password password /silent N:\\)
    • If it’s a Linux drive, use the WinAPI to automatically fill in the GUI prompt
    • When the number of drives has changed a volume has been mounted, so one of the recently tried passwords was used
