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.
