If you thought locking your suitcase with a "TSA-approved" lock would keep your belongings safe from thieves, think again.
Many suitcases include the approved locks, which can be opened by the US Transportation Security Administration to access passengers' luggage for security searches.
The TSA locks are numbered from 001 to 007 – and there's a master key that can access each of them.
However, the security of these master keys was breached in 2014, after a Washington Post report revealed them in a set of photos. While the images were quickly removed, security experts managed to clone all seven master keys using 3D printers, Tech Crunch reported.
