12.8. Cracking WPA-PSK
Of the wireless encryption protocols, WPA is one of the hardest to hack. Let's explore a way to do it. For this we will use two open source security tools, Airforge and Aircrack.
Once a target network using a WPA access point has been identified, using a tool such as KisMAC, you can begin to launch the attack using Airforge to create a deauthentication packet (assuming the current working directory contains the airforge binary).
./airforge <MACaddressofap> <MACofclient> filename.cap
What Airforge will do is cause a user connected to the WAP to become deauthenticated from the network. Once disconnected, the deauthenticated user's system will attempt to reauthenticate, and the SSID will be sent over the air in plain text. ...
