Bluzmanis demonstrated an attack by taking an Interactive CLIQ electro-mechanical lock made by Mul-T-Lock and inserting a mechanical-only key cut to the same keyway. After inserting the key, he does something to vibrate the key for a few seconds until the mechanical motor in the cylinder turns and lifts the locking element to release the lock. He asked Threat Level not to disclose the precise method, other than to say it involves no special tool or skill.Electronic High-Security Locks Easily Defeated at DefCon
"There's no audit trail that the lock has been opened," Tobias says, "because there are no electronics [involved]."

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.
