Ridiculously Insecure Smart Lock
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 can 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.
EDITED TO ADD: The quote at the end is from a different smart lock manufacturer. Apologies for that.
