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.% r' @/ x% S2 X+ G

$ J" W& J$ r* K2 @ rgenpmkis 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.

5 P# n, d; L9 o* QNotice 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.$ k o/ `4 O, R. T$ e! i v& T
