To demonstrate their crack of Medeco's M3 lock for Wired News, Tobias took a lock and inserted one of the keys that he and his researchers designed from Medeco's codes. Then he hit it several times with a bump hammer and turned the key.
The deadbolt was opened just as quickly with an even simpler technique using the wire shim and screwdriver. Tobias pointed out, however, that this cracking technique works only on deadbolts that have a single-sided key entry with a flip switch on one side, not on deadbolts that require a key on both sides of the lock.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
