SubRosaSoft.com has developed a device that it claims can extract passwords from OS X 10.3 or later Macs. The unit consists of a single flash drive that is capable of pulling passwords from the Apple Keychain and system settings. It also compiles a database of the system it’s installed on.
There is one catch though, to purchase one, you have to be an investigator or a law enforcement officer. And yes, you must produce proof. If you can though, the MacLockPick can be yours for just $499.
