With a name like SkyNET, it's got to be scary. This flying robo-hacker deserves its "Terminator"-inspired moniker: Although it stops short of actually hunting humans, it's a potential nightmare for anyone with a wireless home network. Worse, it's a DIYer's dream: cheap and easy to build and fun to operate.
combines a toy helicopter and a computer configured to attack Wi-Fi networks. The result is a drone the CIA would be proud of. The nasty little device can compromise computers on wireless networks and dragoon them into botnets. Botnets are widely used for hacking, denial-of-service attacks, and spamming.
The devious beauty of SkyNET is that by controlling the botnet from a drone rather than an Internet connection, the botmaster is harder to track down. To catch the bad guy you'd have to figure out that a drone is involved, spot the drone, and follow it back to its owner (assuming the black hat goes to pick it up). Either that or catch it and do a full-blown forensic investigation to figure out who made it.
The prototype SkyNET drone is a Parrot AR.Drone quadrocopter modded with a lightweight Linux computer, 3G mobile broadband connection, GPS receiver, and a pair of Wi-Fi cards--one for controlling the drone and one for attacking wireless networks. The whole thing can be built for less than $600. The helicopter goes for $300 on Amazon.
