Forget networked PCs or even PlayStation 3s, components commonly found in plasma TVs are the latest thing in password cracking tools.
High performance FPGA (Field Programmable Gate Array) chips are the Chuck Norris of number crunching, equally suited to image processing and (with a bit of modification) password cracking.
During the Black Hat conference in Washington in February researcher Steve Mueller and David Hulton used FPGA kit in an attack that cracks standard GSM transmissions, encrypted using the A5/1 algorithm, in as little as 30 seconds.
The same technology can be applied to crack Bluetooth transmissions in as little as eight seconds, according to security consultancy SecureTest, which ran a demo of the technology at the recent Infosec conference.
Tom Beale, a consultant at SecureTest, explained that networks of FPGA boards can be linked together for password cracking. The really serious can splash out $120K for high-end FPGA kit from the likes of Pico Computing.
For SecureTest's purposes, FPGA boards from old LG plasma TVs did the job.
