It started as a slow ransomware news week but slowly picked up pace with the Department of Justice announcing indictments on TrickBot and Conti operations members.
On Thursday, the US announced sanctions and three indictments against nine Russian nationals who are alleged members of the TrickBot and Conti ransomware operations for attacks on more than 900 victims worldwide.
“The defendants charged in these three indictments across three different jurisdictions allegedly used their cyber knowledge and capabilities to victimize people and businesses around the world without regard for the damage they caused,” said Acting Assistant Attorney General Nicole M. Argentieri of the Justice Department’s Criminal Division
The individuals were allegedly involved in a wide variety of roles in the Conti ransomware operation, including overall managing of the cybercrime operation, crypting malware so it was undetectable, managing infrastructure, and developing malware, including the TrickBot botnet.
In other news, Cisco confirmed that ransomware gangs are exploiting a zero-day in Cisco VPN appliances after BleepingComputer’s, SentinelOnes, and Rapid7’s reporting on its abuse by the Akira ransomware operation.
Finally, Ragnar Locker claimed an August attack on Israel’s Mayanei Hayeshua hospital, claiming to have stolen 1 TB of data.
