Four members of the REvil ransomware group have been released from custody despite pleading guilty to fraud and malware distribution charges. The case is unrelated to the prolific and high-profile ransomware attacks that the REvil group was noted for before it was shut down in 2021. The four REvil members were among several arrests made by Russian authorities in January 2022 after the US government warned that it would take its own action against Russian ransomware groups if the Kremlin failed to do so. According to Russian state-owned news agency TASS, Muromsky, Bessonov, Golovachuk, and Korotaev confirmed they were involved in REvil activities between October 2015 and January 2022, and primarily targeted US citizens. It is not currently believed that any of them have been, or will be, extradited to the US.
