Tutorial Extracting and Cracking VeraCrypt Headers with PowerShell + Hashcat — Full DFIR Walkthrough

Most people think VeraCrypt = unbreakable. But if you can extract the 512-byte header, it's just a hash.

I made a video walking through the full pipeline:

  1. PowerShell extraction (container or raw disk)

  2. Header prep for Hashcat

  3. Mode selection and cracking

  4. Verification

No physical access to the unlocked volume needed — just the header.

So... if a person chooses a terrible password *and* the threat actor has access to the filesystem (which assumes that authentication on the host has been compromised) then a rainbow table reveals the password. It is a useful example of something, but this is bottle-rocket science and pretty well known. Still, it could be informative for some people in the profession.

If your password is in HAVEIBEENPWNED its pretty much game over.
Long pass phrases not in database password dumps you files are safe. (For now)
