I went back and looked up the event. Rostelecom has been behind a few of these. I might be conflating two of them.

In 2017, Rostelecom grabbed financial & other network data for a few minutes. https://www.thousandeyes.com/blog/rostelecom-route-leak-targ...

In 2020 Rostelecom announced lots of networks they didn't own and got that traffic for an hour. Early analysis felt it was accidental. Not sure about later analysis. https://www.zdnet.com/article/russian-telco-hijacks-internet... https://news.ycombinator.com/item?id=22789754

But 2 months ago, Rostelecom grabbed a chunk of Apple's network (which I missed) https://cybernews.com/apple-network-traffic-went-through-rus...
