Toperform 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.% n: A5 K1 N5 c0 ~0 B: G% L9 }

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.

As youcan see this simple dictionary attack took 51 seconds, we can speed upthis process by precomputing the WPA-PMK to crack the WPA-PSK (seebelow).3 V: D+ D! Q6 k5 z0 P* I, |! r7 l+ x

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.

Notice that cracking the WPA-PSK took 0.04 seconds with the pre-computed attacked as opposed to 200 secondswith standard dictionary attack mode, albeit you do need to pre-computethe hash files prior to the attack. However, precomputing large hashfiles for common SSIDS (e.g. linksys, tsunami) would be a sensible movefor most penetration testers.
