Schneier - Ridiculously Insecure Smart Lock

Tapplock sells an "unbreakable" Internet-connected lock that you can open with your fingerprint. It turns out that:

  1. The lock broadcasts its Bluetooth MAC address in the clear, and you can calculate the unlock key from it.
  2. Any Tapplock account an unlock every lock.
  3. You can open the lock with a screwdriver.
