I have read many articles and many of them state that WPA is dead, well if you read carefully it ain't dead yet. The attack works on WPA networks where TKIP and QoS are used and only partial decryption happens. In fact if you have your AP logging errors to a centtralized server you can even create triggers for the attack for example a Cisco MARS. One has to start the process of securing the wireless networks and start the migration to AES, once Aircrack-ng is updated and further research is done on this attack I do belive that WPA with TKIP will be dead, so you have some time left but you better move it. I highly recommend you give a rear to the article Battered but not Broken in arstechnica.
