Researchers find crippling flaws in global GPS

Researchers have developed three attacks capable of crippling Global Positioning System infrastructure critical to the navigation of a host of military and civilian technologies including planes, ships and unmanned drones.

The scenarios developed include novel remote attacks via malicious GPS broadcasts against consumer and professional- grade receivers which could be launched using $2500 worth of equipment.

A 45-second crafted GPS message could bring down up to 30 percent of the global GPS Continuously Operating Reference Stations (CORS), while other attacks could take down 20 percent of NTRIP networks, security boffins from Carnegie Mellon University and firm Coherent Navigation wrote in a paper. (pdf)

The stations provide global navigation satellite system data to support "safety and life-critical applications", and NTRIP is the protocol used to stream that data online.

Together, attack scenarios created "serious ramifications to safety systems".

"Until GPS is secured, life and safety-critical applications that depend upon it are likely vulnerable to attack," the team of four researchers said.
