Ever wonder how all the remote openers in the world don't set each other off on a regular basis? It all has to do with the mysterious KeeLoq security system, made by Microchip Technology. The system is used by quite a few automakers in their remote keyfobs and in garage door openers to keep things secure. Well, the rascally Germans at Ruhr University decided to figure out how it works, and along the way they developed a way to duplicate those codes. Whoops. When reached for comment, MT relied on a canned statement saying "These theoretical attacks are not unique to the KeeLoq system and could be applied to virtually any security system." Hopefully you've got backup locks for your stuff. [SundayHerald]
