WPS Cracker

reaver -i <interface> -b <target bssid> -vv

Reaver implements a brute force attack against WiFi Protected Setup which can crack the WPS pin of an access point in a matter of hours and subsequently recover the WPA/WPA2 passphrase.

Specifically, Reaver targets the registrar functionality of WPS, which is flawed in that it only takes 11,000 attempts to guess the correct WPS pin in order to become a WPS registrar. Once registred as a registrar with the access point, the access point will give you the WPA passphrase.
