Somebody on twitter “reverse engineered” the exploit. Apparently ms shipped debug code in production. At least it’s not called Backdoor_FBI outright.

How it works:

  1. Recovery tools look for a config file called RecoverySimulation.ini on the OS drive
  2. If Active=Yes, it enables "test mode" for the recovery tools
  3. Test mode unlocks your BitLocker drive but a flag called FailRelock tells it to skip relocking
  4. cmd.exe spawns with full access to your "encrypted" drive
