Wi-Fi Key-cracking Kits Sold in China Mean Free Internet

Wi-Fi Key-cracking Kits Sold in China Mean Free Internet: Dodgy salesmen in China are making money from long-known weaknesses in a Wi-Fi encryption standard, by selling network key-cracking kits for the average user. … 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. [Date: 5 May 2010; Source:]
