Researcher finds vulnerability in WPS protocol, looks for manufacturers to offer fix

On the plus side, your router's mostly secure. Security researcher Stefan Viehbock has just discovered a major security hole which allowed him to use a brute force technique to access a WPS PIN-protected network in about two hours. According to Viehbock, a design flaw allows the WPS protocol's 8-digit PIN security to fall dramatically as additional attempts are made. With each attempt, the router will send a message stating whether the first four digits are correct while the last digit of the key is used as a checksum and then given out by the router in negotiation.
