The FSB of the Russian Federation began to carry out active operational measures against members of the REvil hacker group in August 2021. And in September, the Investigation Department (ID) of the Ministry of Internal Affairs of the Russian Federation filed a petition with the court to seize items and documents containing state or other secrets protected by federal law, as well as to seize information about deposits and bank accounts of persons who were participants in REvil. In January 2022, as part of a case already initiated by the SD, the FSB carried out arrests. Active work, including investigations, began shortly after Joe Biden, during a July 2021 phone call with Vladimir Putin, called on Russia to take action to curb the activities of hackers operating on its territory, “and emphasized that he is committed to continuing combating the broader threat posed by ransomware.”

The Kremlin then reported that Putin declared Russia’s readiness “to jointly suppress criminal manifestations in the information space,” but in the last month there have been no such requests from American departments.
The conversation was about REvil.

In 2021, U.S. businesses and companies experienced several major cyberattacks that brought them to a standstill. One of the loudest was an attack on the Colonial Pipeline, the largest pipeline network on the East Coast of the United States for the supply of gasoline, diesel fuel and other petroleum products. The pumping of petroleum products was stopped for several days. In June 2021, in the United States, all factories of the largest meat producer, JBS SA, were shut down due to a cyber attack. As a result, the management of Colonial Pipeline paid the cybercriminals a ransom of 75 bitcoins ($4.5 million at the time of the transaction).

And so the July conversation between the two presidents led to the fact that an operation was carried out against REvil participants in Moscow, St. Petersburg, Moscow, Leningrad and Lipetsk regions

On January 14, 2022, the FSB announced the final defeat of REvil.
