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

New "spoofing" attacks resulting in total navigation failure have been occurring above the Middle East for months, which is "highly
significant" for airline safety.

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.

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.
One expert Motherboard spoke to said this was "highly significant."

Iran would not be the only country spoofing GPS signals in the region.
As first reported by Politico, Clements was the first to identify
spoofing most likely coming from Israel after Hamas' Oct. 7 attacks.
"The strong and persistent spoofing we're seeing over Israel since
around October 15 is almost certainly being carried out by Israel
itself," Humprheys said. "The IDF effectively admitted as much to a
reporter with Haartz." Humphreys said at the time that crews
experiencing this GPS spoofing could rely on other onboard instruments
to land.

Humphreys said the effects of the Israeli spoofing are identical to
those observed in late September near Iran. "And these are the first
clear-cut cases of GPS spoofing of commercial aircraft ever, to my
knowledge," he said. "That they happened so close in time is
surprising, but possibly merely coincidental."
