Microsoft first discovered the network’s existence in 2012 and named all computers infected with the same malware module Necurs, which automatically runs on the user’s computer and uses its resources to send a lot of spam every day.

Microsoft said that in its 58-day investigation, its engineers tracked a computer on the Necurs network and found that the computer alone sent 3.8 million emails in two months.

In addition, the Necurs network is often leased to other criminal gangs to spread various ransomware, remote access trojans, or steal information trojans.

Microsoft has been granted court authorization to take over Necurs’ existing domain in the United States and has predicted that 6 million domains the network could create over the next 25 months, notifying domain name regulators around the world against future attacks.
