TL:DR: Israel is the source of the spoofing.

Lemmy is starting to feel like Discord with people dropping lazy images like this in every damn thread.

Literally couldn’t even bother to edit the image so the country names are in the image.

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

The article says the spoofing was first recorded in September from Iran, then Israel started doing some after the October Hammas attacks

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”.
Update the spoofed location based on the aircraft’s actual position 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 a location west of 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.

Could you expand on what’s the issue? I’m honestly curious

GPS relies on timing - very precise timing - and signed signals. It might be that GPS units ignore that the signal should be signed, but the (picosecond) timing basically defines an objects’ position in space. A picosecond makes a difference of a few centimeters.
Now, modern planes don’t primarily rely on GPS. They have gyroscopes. But as gyroscopes lose precision over the duration of the flight, they cross-reference with GPS to fix this loss of precision. But for that, the measured GPS location must be close enough to the gyroscope-based location, or the GPS result is discarded as erroneous. So one needs not only to spoof any GPS signal, it must be close enough to the actual position, and then slowly move the target over.
BTW, the villains in the movie “Tomorrow never dies” use a different approach. They influence the GPS satellites directly, which is a totally different thing, and if Iran did attempt that, I think the US would react differently and … more directly.

Wow. The state of Israel is really piling on the reasons to hate it these days.

It was doing this for decades but Western countries only start hearing about it.
Social media have prevailed over classic media, and this time they have proven to be harder to steer.
