Remember wardriving? That's the term for driving around with sensors to detect open wi-fi routers with the goal of mapping or using them. This weekend security researcher Gene Bransfield spoke at the DefCon hacker convention about a device to do just that, but for his cat. The collar includs a Spark Core chip loaded with his custom-coded firmware, a Wi-Fi card, a tiny GPS module and a battery. The device, dubbed WarKitteh can be built for under $1000. And, Bransfield made clear he built it to amuse himself rather than to find and abuse open wi-fi. He did report in his talk, however, how many WEP-enabled access points he found. That security system is known to be insecure.
I am impressed at how far we've come since the basic cat-tracking Don Cooke did in his Fun with GPS book from 2005 (right).
