Europol and several private technology companies announced the takedown of the Ramnit botnet. The operation shut down the botnet s command and control infrastructure and redirected traffic from 300 domains used by Ramnit to domains controlled by authorities. More than 3.2 million Windows computers have been infected by the malware, Europol said. Ramnit was spread via spam campaigns, phishing scams and drive-by downloads, enticing victims to unwittingly install the malicious code. The attackers then had access to the infected machine and used it to steal primarily banking credentials, but also passwords.
