The winner (if we didn't already know) is BackTrack 4.
BT4, Live Hack CD in Hacking Thursday, May 6, 2010 at 10:19AM With one of the "network-scrounging cards," or "ceng wang ka" in Chinese, a user with little technical knowledge can easily steal passwords to get online via Wi-Fi networks owned by other people.
The main piece of the kits, an adapter with a six-inch antenna that plugs into a USB port, comes with a CD-ROM to install its driver and a separate live CD-ROM that boots up an operating system called BackTrack. In BackTrack, the user can run applications that try to obtain keys for two protocols used to secure Wi-Fi networks, WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access). After a successful attack by the applications, called Spoonwep and Spoonwpa, a user can restart Windows and use the revealed key to access its Wi-Fi network.
To crack a WEP key, the applications exploit weaknesses in the protocol that have been known for years. For WPA, they capture data being transmitted over the wireless network and target it with a brute-force attack to guess the key.
