Wi-Fi Protected Setup PIN Brute Force Vulnerability

A researcher has discovered a security hole in WPS technology that affects millions of Wi-Fi routers around the world. A few weeks ago I decided to take a look at the Wi-Fi Protected Setup (WPS) technology. I noticed a few really bad design decisions which enable an efficient brute force attack, thus effectively breaking the security of pretty much all WPS-enabled Wi-Fi routers. As all of the more recent router models come with WPS enabled by default, this affects millions of devices worldwide.
