The US Department of Justice, working with the cybercrime-fighting agency within the US Department of Defense known as the Defense Criminal Investigative Service, announced that it had dismantled four massive botnets in a single operation, removing the command-and-control servers used to commandeer the hacker-run armies of compromised devices known by the names JackSkid, Mossad, Aisuru, and Kimwolf.
"The dismantled malware infrastructure consisted of hundreds of thousands of infected computers containing several million stolen credentials. Many of the victims were not aware of the infection of their systems," Europol said.
