The Internet of Things is a bigger danger than most people realize: Pretty much all home Wi-Fi routers can be hacked, which is a problem if you've already adopted connected light bulbs and faucets.
Gene Bransfield, a cybersecurity expert from Washington, recently built a gadget he calls the WarKitten. It's a cat collar equipped with a Spark Core Wi-Fi device and a GPS module. Bransfield put the collar on a Siamese cat named Coco and let him roam the neighborhood, all the while mapping the available Wi-Fi networks.
The gadget found 23, more than a third, using obsolete Wired Equivalent Privacy encryption for network passwords instead of the more up-to-date Wi-Fi Protected Access. Tutorials on how to break WEP encryption abound on the Internet.
