Rostelecom carries out hacker attacks?

Question

Information Security

What happened to Rostelecom?
Websites do not open for me - in the news they say that the equipment of only those xDSL subscribers who refused to rent from Rostelecom, but bought their own, was subjected to a hacker attack.
Who knows what kind of attack Rostelecom carried out?

Answer 1

Specifically, which models were attacked - do not write. But people, as a rule, do not update the firmware for years - it works. It happens that admin / admin do not change :)

Answer 2

They say there was an attack on the end user equipment of Rostelecom... Old firmware of network equipment and modems were used. While it's hard to tell in real life...
