REvil is believed to have targeted a meat supplier and a major information technology supplier in recent months. The move hit businesses in the United States and beyond by locking them out of their systems while REvil demanded money to stop the attack.
When asked if the administration had taken action against these cybercriminals in Russia, the senior official did not respond.
On REvil in particular, “We have certainly noticed that they have suspended their operations. We don’t know exactly why, ”the official said. “But we are still pressuring Russia to take action against cybercriminals operating in its territory. We are not claiming victory.
When asked if the Kremlin had dismantled the group or forced the group to dismantle its sites, the official replied: “It’s possible, I guess. Again, we’re not sure why they pulled out. The official spoke on condition of anonymity according to the ground rules set by the administration.
The United States did not directly link REvil’s attacks to the Kremlin. But President Joe Biden has warned Russian leader Vladimir Putin that his government must act against such criminal organizations and that the United States will act against them if necessary.
Biden’s aides have said tackling the growing threat of ransomware is a priority for the United States, and they are using a variety of measures to bring unprecedented attention to the threat.
But given the highly classified nature of America’s cyber capabilities, combating ransomware is also a difficult topic for them to tackle. Over the past week, administration officials have been cautious when asked what led to REvil’s online takedown.
Over the weekend, another senior administration official said the United States was monitoring publicly available information while monitoring the case.
“At least looking at the open source information, the REvil spokesperson’s account may have been banned from Russian hacking channels,” the official said. “And we continue to see that the REvil infrastructure remains down. We think this is a very positive thing.
