Wi-Fi Protected Setup (WPS)

The WPS standard was developed in 2007 by the Wi-Fi Alliance (a trade association that promotes wireless LAN technology and certifies products if they conform to certain standards of interoperability) to allow home users who know little of wireless security to set up WPA2 as well as making it easy to add new devices to an existing network. In December 2011 researcher Stefan Viehböck reported a design and implementation flaw to the US-CERT. The flaw makes brute-force attacks against PIN-based WPS feasible to perform on WPS-enabled Wi-Fi networks. The vulnerability note is available on the US-CERT’s web site.
