BackTrack: Pyrit demonstration (GPU cracking video)

Pyrit takes a step ahead in attacking WPA-PSK and WPA2-PSK, the protocols that protect today’s public WIFI-airspace. Pyrit’s implementation allows to create massive databases, pre-computing part of the WPA/WPA2-PSK authentication phase in a space-time-tradeoff. The performance gain for real-world-attacks is in the range of three orders of magnitude which urges for re-consideration of the protocol’s security. Exploiting the computational power of Many-Core- and other platforms through ATI-Stream, Nvidia CUDA, OpenCL and VIA Padlock, it is currently by far the most powerful attack against one of the world’s most used security-protocols. For more background see this article on the project’s blog.

In this video, PureH@te Short demos the passthrough option of pyrit which eliminates the need for giant tables taking up all your hard drive space.
