Think those belongings are safe in that gym and high school locker of yours? You may want to think again.

A few weeks ago, hacker Samy Kamkar demonstrated just how easily he could crack a Master Lock combination lock in less than eight attempts using nothing more than a simple mathematical algorithm. In the tail-end of his video, he also hinted that he had been working on an Arduino-based, motorized cracking machine that would be capable of doing all the legwork for him. The Maker said the device would be introduced in the very near future.


And well, the future is now. As a way to highlight a vulnerability in one of the world’s most ubiquitous brands of combination locks, the Maker has created a battery-powered, 3D-printed robot that can pop open any locker in as little as 30 seconds. Simply attach the aptly dubbed Combo Breaker to any of the countless Master Locks, turn it on and let it get to work.
