Jones also said school shootings didn't really happen. He's a grifter who gets paid pedaling bat poop craziness... A Cyber attack from Russia is definitely not beyond the realm of possibility. They have a long history of trying to interfere in other countries Democratic process
If I was fighting a war with Ukraine and the US was helping them I might have a targeted attack on the US. I would want to do something to the military pipeline supplying Ukraine. But if there were a cyber attack on an airforce base or Naval base it wouldn't be a big story in the paper. The military would want to keep it quiet.
However, doing a cyber attack on Laguardia and O'Hare makes no sense at all to me if I am in Russia fighting Ukraine.
On the flip side you cancel a bunch of flights in NY and Chicago the whole country will become aware of this and it will be all over the news.
There is no strategic reason for Russia to shut down domestic flights going through Laguardia, however, it you want to manipulate a gullible populace it would be a very high visibility target.
