Serial hacker Samy Kamkar has released all the hardware and software specifications that hobbyists need to build an aerial drone that seeks out other drones in the air, hacks them, and turns them into a conscripted army of unmanned vehicles under the attacker's control.
Dubbed SkyJack, the contraption uses a radio-controlled Parrot AR.Drone quadcopter carrying a Raspberry Pi circuit board, a small battery, and two wireless transmitters. The devices run a combination of custom software and off-the-shelf applications that seek out wireless signals of nearby Parrot drones, hijack the wireless connections used to control them, and commandeer the victims' flight-control and camera systems. SkyJack will also run on land-based Linux devices and hack drones within radio range. At least 500,000 Parrot drones have been sold since the model was introduced in 2010.
