Masterzorag has posted a video on his blog about running Pyrit on a Playstation3, utilizing the Cell B.E. processor. As far as I know, this is the very first case of using the Playstation3 or the Cell B.E. for attacking WPA(2)-PSK.
Please notice that this video and the related information is provided by Masterzorag. Please ask questions on his blog, I’m just hotlinking the video here :-)
