It was discovered by Fluhrer, Mantin and Shamir back in 2001, that shows that after about ten to the six of, after about a million frames. You can recover the secret key. Can recover key. So, this is kind of a disastrous attack that says essentially all you have to do is listen to a million frames.

WebSyncScan is described, a low-cost technique for continuously tracking nearby base stations by synchronizing short listening periods at the client with periodic transmissions from each base station and it is demonstrated that it allows better handoff decisions and over an order of magnitude improvement in handoff delay. WebThe Fluhrer, Mantin and Shamir (FMS) attack, published in their 2001 paper "Weaknesses in the Key Scheduling Algorithm of RC4", takes advantage of a weakness in the RC4 key scheduling algorithm to reconstruct the key from encrypted messages.
