Drone Hijacking? That’s Just the Start of GPS Troubles

Drone Hijacking? That’s Just the Start of GPS Troubles

On the evening of June 19, a group of researchers from the University of Texas successfully hijacked a civilian drone at the White Sands Missile Range in New Mexico during a test organized by the Department of Homeland Security.

The drone, an Adaptive Flight Hornet Mini, was hovering at around 60 feet, locked into a predetermined position guided by GPS. Then, with a device that cost around $1,000 and the help of sophisticated software that took four years to develop, the researchers sent a radio signal from a hilltop one kilometer away. In security lingo, they carried out a spoofing attack.

“We fooled the UAV (Unmanned Aerial Vehicle) into thinking that it was rising straight up,� says Todd Humphreys, assistant professor at the Radionavigation Laboratory at the University of Texas.

Deceiving the drone’s GPS receiver, they changed its perceived coordinates. To compensate, the small copter dove straight down, thinking it was returning to its programmed position. If not for a safety pilot intervening before the drone hit the ground, it would have crashed.

But for Humphreys playing the part of an evil genius in a thriller movie, everything worked exactly to plan. “It was beautiful,� he tells Danger Room.

What’s worse, the experiment at White Sands shows that drone-jacking is “just the tip of the iceberg of a much bigger security issue we have in this country,� according to Logan Scott, a GPS industry consultant who has worked for defense giants like Lockheed Martin.

In other words, it’s not only about drones, it’s GPS in general that is not safe.

“The core problem is that we’ve got a GPS infrastructure which is based on a security architecture out of the 1970s,� Scott tells Danger Room. “From a security point of view, if you look at GPS’s current status, is more or less equivalent to operating computers without firewalls, with no basic checks.�
