If it’s this widespread then it either has to be AA maintenance (perhaps a team having a bit of reputational mutiny because AA management pockets tons of cash and exploits cheap contractors and constantly bitches about pilot pay but wouldn’t fly planes without pilots) or it’s remote. As an audio person, musician, producer blah blah, that is totally human. Likely recorded and filtered a few times. By the inflections I think Eastern European. The sound of it reminds me of a Slavic based vocal upbringing. Doesn’t seem like North Korean, Latin, or North American to me. Probably about a couple minutes of audio looping somehow at the source. Far too many for it to be a hardware exploit because honestly who wants to invest that much in this kind of prank? This isn’t Zug Super Bowl level[0]. My guess is they’re coming through the least secure provider for a third party service - probably the WiFi enterprise thru being on the inside of them - and AA is their first playground where people are noticing. How they get from there to the intercom is probably buried deep in a couple audio wires plugged into overlapping sources unintentionally or there is some kind of frequency band that isn’t shielded properly so it’s possible to push the audio signal over something else and cause garbled noise and almost impossible to find. Like, in the past it was funny when picking up FM radio signals through my guitar amp, but it sucked when trying to have a serious jam session and talk between playing. Audio signals can be really powerful compared to other delicate systems IMO. Definitely curious and want to see how this unfolds!
