Members of the hacker group, also known as Sodinokibi, have been charged with crimes in Russia, and its infrastructure has “been liquidated,” the public relations arm of Moscow’s FSB security agency told Russia’s Interfax news agency.

The special operation, conducted by Russian authorities, was reportedly at the request of the United States.

“The FSB of Russia has established the full composition of the REvil criminal community and the involvement of its members in the illegal circulation of means of payment, and documentation of illegal activities has been carried out,” a translated statement from the intelligence service said.
