Shrinky Dinks As a Threat To National Security 257

InflammatoryHeadlineGuy writes "What do Shrinky Dinks, credit cards and paperclips have in common? They can all be used to duplicate the keys to Medeco 'high-security' locks that protect the White House, the Pentagon, embassies, and many other sensitive locations. The attack was demonstrated at Defcon by Marc Weber Tobias and involves getting a picture of the key, then printing it out and cutting plastic to match — both credit cards and Shrinky Dinks plastic are recommended. The paperclip then pushes aside a slider deep in the keyway, while the plastic cut-out lifts the pins. They were able to open an example lock in about six seconds. The only solution seems to be to ensure that your security systems are layered, so that attackers are stopped by other means even if they manage to duplicate your keys."
