Tapplock sells an "unbreakable" Internet-connected lock that you can open with your fingerprint. It turns out that:
- The lock broadcasts its Bluetooth MAC address in the clear, and you can calculate the unlock key from it.
- Any Tapplock account an unlock every lock.
- You can open the lock with a screwdriver.
Regarding the third flaw, the manufacturer has responded that "...the lock is invincible to the people who do not have a screwdriver."
You can't make this stuff up.
