As we know, there are ransomware groups who attack the targets and extract money. The US at the highest level had demanded that Russia should shut down such groups. REvil, short for Ransomeware Evil, the most aggressive of the groups, went offline in July 2021. The group’s sites on the dark web suddenly disappeared. Happy blog — their publicity material listing the victims and earnings — too was gone. They have virtual conference rooms to negotiate with the victims. They too disappeared. May be, the US asking their Cyber Command and FBI to take down the sites worked. Maybe, Russia at the highest level ordered its shutting down. May be REvil itself took the decision fearing the consequences when two powers were after it.
