The earlier attack, developed by researchers Martin Beck and Erik Tews, worked on a smaller range of WPA devices and took between 12 and 15 minutes to work. Both attacks work only on WPA systems that use the Temporal Key Integrity Protocol (TKIP) algorithm. They do not work on newer WPA 2 devices or on WPA systems that use the stronger Advanced Encryption Standard (AES) algorithm.
As more and more functions get pushed into embedded devices that don’t get updated on a regular basis, this problem is going to get worse and worse. Anybody else have routers and such that are 5 years old?
