About wpacracker.com
WPA Cracker is a cloud cracking service for penetration testers and network auditors who need to check the security of WPA-PSK protected wireless networks. WPA-PSK networks are vulnerable to dictionary attacks, but running a respectable-sized dictionary over a WPA network handshake can take days or weeks. WPA Cracker gives you access to a 400CPU cluster that will run your network capture against a 135 million word dictionary created specifically for WPA passwords.
