The new WPA Cracker service offers to crack a WPA protected network password in 20 minutes for a fee of $34. It’s billed as a tool to help network auditors and penetration testers check the security of their networks.

“It works because of a known vulnerability in Pre-Shared Key (PSK) networks, which are used by some home and small-business users,” writes Computerworld’s Robert McMillan.

“The service was launched by a well-known security researcher who goes by the name of Moxie Marlinspike,” McMillan writes. “In an interview, he said that he got the idea for WPA Cracker after talking to other security experts about how to speed up WPA network auditing.”
