Commercial Flights Are Experiencing 'Unthinkable' GPS Attacks and Nobody Knows What to Do

Commercial air crews are reporting something “unthinkable” in the skies above the Middle East: novel “spoofing” attacks have caused navigation systems to fail in dozens of incidents since September. 

In late September, multiple commercial flights near Iran went astray after navigation systems went blind. The planes first received spoofed GPS signals, meaning signals designed to fool planes’ systems into thinking they are flying miles away from their real location. One of the aircraft almost flew into Iranian airspace without permission. Since then, air crews discussing the problem online have said it’s only gotten worse, and experts are racing to establish who is behind it.

OPSGROUP, an international group of pilots and flight technicians, sounded the alarm about the incidents in September and began to collect data to share with its members and the public. According to OPSGROUP, multiple commercial aircraft in the Middle Eastern region have lost the ability to navigate after receiving spoofed navigation signals for months. And it’s not just GPS - fallback navigation systems are also corrupted, resulting in total failure.

According to OPSGROUP, the activity is centered in three regions: Baghdad, Cairo, and Tel Aviv. The group has tracked more than 50 incidents in the last five weeks, the group said in a November update, and identified three new and distinct kinds of navigation spoofing incidents, with two arising since the initial reports in September. 

While GPS spoofing is not new, the specific vector of these new attacks was previously “unthinkable,” according to OPSGROUP, which described them as exposing a “fundamental flaw in avionics design.” The spoofing corrupts the Inertial Reference System, a piece of equipment often described as the “brain” of an aircraft that uses gyroscopes, accelerometers, and other tech to help planes navigate.
