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.
TL:DR: Israel and Iran are the source of the spoofing.

And Russia was doing it just a few years ago, too.

Iran has been doing this shit for decades. I’m sure Israel has too.
Basically, they figure out what a GPS receiver would hear if it was receiving signals from a specific location, say “London”. They then broadcast those exact signals. Any receiver that hears them now thinks it is in “London”.
Start with the aircraft’s actual position, and update the spoofed location based where it actually is and and its intended destination, and you can get it to go where you want it.
If the aircraft is trying to fly to London, for example, and you want it to turn to the east of its track, you start spoofing that it has drifted west on its track to London. The aircraft thinks it is west of London, and turns to the east to get to spoofed-London.
Actually, the issue is far more complicated than that.
The article says the spoofing was first recorded in September from Iran, then Israel started doing some after the October Hammas attacks
