Hackerbot is a two-wheeled autonomous robot created by Eric Johanson, Paul Holman and others to roam through areas using WiFi networks, detecting and logging insecure transmissions. Despite the name, the robot seems to act more like a cracker, not a hacker. The 40lbs, battery powered robot was demonstrated at the recent Defcon convention in Las Vegas. According to Eric, Hackerbot's code will be released shortly as Free Software licensed under the GNU GPL. Other stories about Hackerbot can be found on News.com, MSN news, and Slashdot.
