“There is a price that comes with simplicity — and when it
comes to security, that price is often increased risk. That’s
exactly what is now happening with Wi-Fi Protected Setup (WPS),
which is intended to be a simple way for consumers to configure
security settings on wireless networks at home.
Over the holidays, a detailed white paper was released by
security researcher Stefan Viehbock, titled, “Brute Forcing Wi-Fi
Protected Setup.” In the paper, Viehbock explains that there are
design and implementation flaws in WPS that make it exploitable,
leaving wireless networks at risk. The weakness comes by way of the
PIN that is used to activate WPS.
