coWPAtty Dictionary Attack:
2 ~# a. r' p6 M5 aToperform the coWPAtty dictionary attack we need to supply the tool witha capture file that includes the TKIP four-way handshake, a dictionaryfile of passphrases to guess with and the SSID for the network.
J3 c+ N/ Q, K3 O8 H
In orderto collect the four-way handshake you can either wait until a clientjoins the network or preferably you can force it to rejoin the networkusing tools like void11 or aireplay and capture the handshakes usingsomething like kismet, ethereal or airodump.

genpmkis used to precompute the hash files in a similar way to Rainbow tablesis used to pre-hash passwords in Windows LANMan attacks. There is aslight difference however in WPA in that the SSID of the network isused as well as the WPA-PSK to "salt" the hash. This means that weneed a different set of hashes for each and every unique SSID i.e. aset for "linksys" a set for "tsunami" etc.

Now wehave created our hash file we can use it against any WPA-PSK networkthat is utilising a network SSID of cuckoo. Remember the capture(wpa-test-01.cap) must contain the four-way handshake to be successful.

However, precomputing large hashfiles for common SSIDS (e.g. linksys, tsunami) would be a sensible movefor most penetration testers.

coWPAtty4.0 is also capable of attacking WPA2 captures. Note: The same hashfile as was used with the WPA capture was also used with the WPA2capture.
