In a presentation to the DEF CON, hacking conference in Las Vegas security in August, 16 Bluetooth researcher Anthony Rose detailed how to easily hack 16 Bluetooth padlocks with inexpensive kit. Only four of them did not crack including the Master Lock Bluetooth padlock.

During the 24th edition of the DEF CON hacking conference held this summer in Las Vegas, several Bluetooth locks have been tested by a team of engineers and the results are inconclusive : out of sixteen Bluetooth enabled devices, twelve do not offer the expected security. Some devices stored passwords in plain text. Anyone with a Bluetooth sniffer could gain access. Other locks were vulnerable to replay attacks, which means the researchers grabbed data over the air when a legitimate user unlocked the lock, and they then just replayed that data to gain access. Some of the other attacks were a bit more intricate, although still fairly basic! Only four padlocks have resisted the assaults, Master Lock Bluetooth padlocks is one of them!
