  1. A few weeks ago, renowned security expert / hacker / entrepreneur Samy Kamkar detailed a method that can be used to crack any Master Combination Lock by hand in just eight tries or less. Now, he’s automated the process using a 3D printed, Arduino-powered robot he calls Combo Breaker.

    The mechanical hack takes advantage of a vulnerability in the combination lock that Kamkar details in a different video. While it’s neat to watch and learn what’s going on, it’s pretty much common knowledge that you shouldn’t use something as simple as a basic combination lock if you want something locked up to remain that way.

    Actually, I was more impressed with his ability to move around the CAD app.

    Not very useful, but pretty cool in the engineering.

    As someone who has taken up lock picking as a hobby, locks are nothing more than a false sense of security. Locks keep honest people honest. If you really want to keep something safe don't let anyone know you have it to steal.

    I have known about this "hole" with "Master" combo locks for years, as in about 40-years. If you really want a lock that is more difficult to pick, get a lock that has a circular key, or else bring a nice bolt cutter. :)
