Security researcher Gene Bransfield has figured out a fun way to map the vunerable Wi-Fi networks in his neighborhood. As reported in Wired, he outfitted his cat Coco with a specially-made collar built from a Wi-Fi card, GPS module, battery, and a Spark Core chip. The device runs custom software that looks for Wi-Fi signals and records ones that are open or poorly protected with old encryption like WEP, which can be easily broken.
