About Pyrit

Pyrit takes a step ahead in attacking WPA-PSK and WPA2-PSK, the protocol that today de-facto protects public WIFI-airspace. The project’s goal is to estimate the real-world security provided by these protocols. Pyrit does not provide binary files or wordlists and does not encourage anyone to participate or engage in any harmful activity. This is a research project, not a cracking tool.

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 GPUs, Pyrit is currently by far the most powerful attack against one of the world’s most used security-protocols.

    hi there,

    can you please explain, why the attack over the network has been removed? i mean the “serve” cmd.

    best regards,

    stephan

      The implementation was based on HTTP and did not meet my expectations. Therefor it was removed in order not to block the release of version 0.2.3.

      It will probably come back some time around 0.2.5

    Have you seen the open source project GPU at: gpu.sourceforge.net? Unfortunately right now they only have a windows version of this, however, I’m wondering if it is possible to implement a similar functionality in pyrit to share cpu resources via a p2p platform….

    Hey,
    Very nice job!

    I got only one question:
    The new Intel integrated GPUs (4500MHD) can help in decoding HD-movies, so they are able to do some generic computing – which means, in my opinion, that perhaps pyrit can use it (sure it needs work, but it seems to be possible).

    Can you confirm this?
    Thank you!

      AFAIK the 4500MHD has no generic API.

      So no Pyrit-support for it
