Relative to this discovery.
We are a Cisco lwapp shop with 4404 controllers and WCS on 5.1 code.
Does anyone know of a way to obtain the info on the number of clients
connecting with WPA/TKIP. Our secure ssid allows mixed WPA/TKIP/WPA2/
AES clients.
Thanks

The short list of points:
1. Only affects WPA (NOT WPA2)
2. Only affects TKIP (NOT AES)
3. Only affects traffic from router to PC (NOT PC to router)
Can also be used to send bogus info from router to PC
4. Takes approx 12-15 minutes to crack key
5. Some of the code used to demonstrate this was added to Aircrack-
ng two weeks ago.
Authors state this is not the dictionary attack that has been around
for awhile, but a new way to "trick" the router into sending the
attacker larges amount of data, and a new cryptographic attack that
decodes the WPA TKIP key.
