The raids took place following requests from the United States, which has been a major victim of ransomware attacks by REvil.

Previous action has been taken against REvil, including suspected members being arrested in Romania and Ukraine, but the raids by the FSB is the first time Russian authorities have taken action against the group.

One of the most significant alleged REvil attacks targeted Kaseya, an IT solutions developer for MSPs and enterprise clients. REvil was also accused of being responsible for a major ransomware attack against food supplier JBS, which paid$11 million in Bitcoin to the attackers in exchange for the key required to decrypt the network.

Last year, the United States and other G7 countries warned Russia that it needed to take responsibility for ransomware and other cyber criminal groups operating within its borders. Ransomware has become one of the biggest cybersecurity issues facing the world today, with attacks against every sector resulting in disruption.

High-profile incidents have seen hospitals and healthcare services, energy suppliers and local governments hit with ransomware attacks, preventing people from being able to access vital services they need.
