From the What Could Go Wrong file, “serial hacker” Samy Kamkar has developed the hardware and software instructions to build a drone that “seeks out other drones in the air, hacks them, and turns them into conscripted army of unmanned vehicles under the attacker’s control.”

The project is called SkyJack and runs “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.”

At least 500,000 models have been sold since its introduction in 2010.

Said creator Kamkar, “How fun would it be to take over drones, carrying Amazon packages… or take over any other drones, and make them my little zombie drones,” Kamkar asked rhetorically in a blog post published Monday. “Awesome.”

Indeed.
