Over 1,000 Citadel botnets were being used to control millions of malware-infected PCs. Authorities believe the botnets stole over $500 million from consumer and business bank accounts. The botnets infected more than 5 million PCs located in 90 countries, including the United States, Australia, Hong Kong, India and large parts of Western Europe. Microsoft filed a civil lawsuit against the botnet “herders” running 1,463 Citadel botnet botnets last week. The operation marks the first time law enforcement and the private sector have worked together in this way to execute a civil seizure warrant as part of a botnet disruption.”]
