Great video, as always, posted by Vivek Ramachandran on SecurityTube.

This time, Vivek explains how to attack PEAP networks.  In a short resume, a Honeypot is setup with a roge AP and a Radius server in order to get the challenge and response  (802.1X) sent when a unaware user connects to our system.

Once we have captured the challenge and the response sent to our own Radius server, we can use the tool called asleap, written by Joshua Wright, that will brute-force the password with a dictionary attack.
