SAN FRANCISCO (KGO) -- Cats are awesome, and one security engineer is making them even more awesome by transforming them into "WarKittehs" -- cats that are capable of scouting for Wi-Fi hackers.Gene Bransfield equipped a cat with a device that can detect when wireless networks are vulnerable to attack.Bransfield said the idea is pretty simple. The cat roams a neighborhood and the device maps wireless networks, detecting which ones aren't secured. From there, the hacker can squat outside a location and go to work."If I'm going to do some sort of hacking or some sort of malicious activity, I won't want to do it from my house because they can track me to there. I can go to somebody else's house, connect to their Wi-Fi hotspot through their open Wi-Fi, and then if you want to do hacking or something terrible like child pornography, you can download it via that open Wi-Fi access point. And when the FBI shows up, they're going to show up where that access point was, not the guy who connected to it," Bransfield said.He said a third of the two dozen wireless networks his cat scanned were vulnerable. In order to protect themselves, wireless users should set their routers to use the latest encryption method, WPA 2
