# coWPAtty
Notes
-------
Implementation of an offline dictionary attack against WPA/WPA2 networks using PSK-based authentication (e.g. WPA-Personal).
Many enterprise networks deploy PSK-based authentication mechanisms for WPA/WPA2 since it is much easier than establishing the necessary RADIUS, supplicant and certificate authority architecture needed for WPA-Enterprise authentication. Cowpatty can implement an accelerated attack if a precomputed PMK file is available for the SSID that is being assessed.
