alphadogg writes "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. Wi-Fi USB adapters bundled with a Linux operating system, key-breaking software, and a detailed instruction book are being sold online and at China's bustling electronics bazaars. The kits, pitched as a way for users to surf the Web for free, have drawn enough buyers and attention that one Chinese auction site, Taobao.com, had to ban their sale last year. 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 kits are also cheap. A merchant in a Beijing bazaar sold one for 165 yuan ($24), a price that included setup help from a man at the other end of the sprawling, multistory building."
