    AirSnort is a wireless LAN (WLAN) tool which recovers encryption keys.
    AirSnort operates by passively monitoring transmissions, computing the
    encryption key when enough packets have been gathered.
    802.11b, using the Wired Equivalent Protocol (WEP), is crippled with
    numerous security flaws. Most damning of these is the weakness
    described in "Weaknesses in the Key Scheduling Algorithm of RC4 " by
    Scott Fluhrer, Itsik Mantin and Adi Shamir. Adam Stubblefield was the
    first to implement this attack, but he has not made his software
    public. To the best of the authors' knowledge, AirSnort is the first
    publicly available implementation of this attack.
    AirSnort requires approximately 100M-1GB of data to be gathered. Once
    enough packets have been gathered, AirSnort can guess the encryption
    password in under a second.
