Cracking A Combo Lock In Under 30 Seconds

Forget the combination to your combo lock? Well if you’ve got a 3D printer, an Arduino, a servo and a stepper motor handy — you can build your own Combo Breaker pretty easily. It’s capable of solving any Master combination lock in 8 tries or less.

The creator [Samy Kamkar] is a privacy and security researcher, who absolutely loves finding holes in security. We actually just heard from him at our very own Hack a Day Prize: Los Angeles event, where he talked about his wireless keyboard sniffer he built into a cellphone charger.

He’s previously shown us how to crack a combo lock in 8 tries or less using an online calculator he made. This project is just an extension of that to automate the whole process.

As always he gives an extremely thorough explanation of the project in his build log video — including designing the 3D printed parts! If you wanna build your own it’ll cost just under $100 and you can grab all the necessary info and source files from his GitHub.
