Sparrowvsrevolution writes: At the Defcon security conference in Las Vegas, Marc Weber Tobias and Toby Bluzmanis plan to demonstrate simple hardware hacks that expose critical security problems in Swiss lock firm Kaba’s E-plex 5800 and its older 5000. Kaba markets the 5800 lock, which Bluzmmanis says can cost as much as $1,300, as the first to integrate code-based access controls with a new Department of Homeland Security standard that goes into effect next year and requires identifying credentials be used in secure facilities to control access. One attack uses a mallet to "rap" open the lock, another opens the lock by putting a pin through the LED display light to ground a contact on the circuit board, and a third uses a wire inserted in the lock's back panel to hit a switch that resets its software.
