Military Scrambles To Patch Vulnerable Drone Software

Drones may be at the center of the U.S. campaign to take out extremists around the globe. But there's a "pervasive vulnerability" in the robotic aircraft, according to the Pentagon's premier science and technology division — a weakness the drones share with just about every car, medical device and power plant on the planet.

The control algorithms for these crucial machines are written in a fundamentally insecure manner, says Dr. Kathleen Fisher, a Tufts University computer scientist and a program manager at the Defense Advanced Research Projects Agency. There's simply no systematic way for programmers to check for vulnerabilities as they put together the software that runs our drones, our trucks or our pacemakers.

In our homes and our offices, this weakness is only a medium-sized deal: developers can release a patched version of Safari or Microsoft Word whenever they find a hole; anti-virus and intrusion-detection systems can handle many other threats. But updating the control software on a drone means practically re-certifying the entire aircraft. And those security programs often introduce all sorts of new vulnerabilities. "The traditional approaches to security won't work," Fisher tells Danger Room.
