GPS spoofing
...
GPS jamming -
Wouldn't doubt it for one minute. Regular event in the eastern Mediterranean.
Years ago it was suggested there was a GPS jammer on every 'telegraph pole' across mother russia. Leaves them with Glonass unfettered.
From the linked article ......
The problem is not so much when the GPS signal is lost, but when the signal is spoofed - meaning - you still get a recognisable signal and therefore no warning, but it puts you somewhere else ... ie, it tells you that you are where you think you are - but you ain't ....

The easy solution to this is a cheap multi mode NAV receiver module enabling GLONASS and Galileo on your GPS. Avail for GA aircraft ( my aircraft is equipped) but not for large airliners mainly due to a US rule prohibiting to use Russian technology on any of its avionics...

Given the fairly large navigation accuracy tolerances when in the cruise I have never known it to account for more than a warning message on the box. In approach it is obviously more of a pain (limiting approach type options) but I can’t remember it ever making much practical difference either. East of Cyprus is the classic area I used to come across it. In a war situation and with active spoofing things may be different.

But then there seem to be GPS only airports?Lithuanian airline Transaviabaltika said it had been forced to cancel 18 flights between Helsinki and Savonlinna in eastern Finland after the lack of GPS made it impossible to land because Savonlinna airport does not have alternative navigation equipment.
“We have made three attempts to fly to Savonlinna. So far, we have not succeeded,” Rene Must, a manager from Transaviabaltika told Reuters.

Perhaps elimination of energy-intensive back-up nav equipment is part of an initiative to reduce Savonlinna's GHG emissions ...
The facility is scheduled to close for renovations from 2022.05.02 to 2022.06.24. From a FINAVIA announcement:

It seems to be when the interference causes one GPS to have no signal and the other to come back but thinking it’s in the Southern Hemisphere.
It has happened 3 times to me now on the A320.

Long term lurk here but this might be of use.
ADSBExchange has a flag where it can show a/c reporting degraded GPS on ADSB.
globe. adsbexchange. com/?badgps (not sure i can post active links but basically ADSB Exchange site with the flag ?badgps after it).
Obviously a single aircraft in a place is likely just something unrelated but whole groups of aircraft showing it in a cluster is highly suggestive. Just needs nearby traffic in an area to report it.
Kaliningrad showed this last night and the well known cluster out of Syria, Kirkuk along with Ankara, Istanbul and Moscow show up every day.
