Cowpattyis implemented on an offline dictionary attack against WPA/WPA2 networks utilizing PSK-based verification (e.g. WPA-Personal). Cowpatty can execute an enhanced attack if a recomputed PMK document is accessible for the SSID that is being assessed.
coWPAtty is a C-based tool to run an offline dictionary attack against Wi-Fi Protected Access (WPA/WPA2) and audit pre-shared WPA keys using Pre-Shared Key (PSK)-based authentication. coWPAtty is capable of implementing an accelerated attack if a precomputed Pegasus Mail Keyboard (PMK file) is available for the Service Set Identifier (SSID).
