Microsoft Corp said it has freed at least 4.7 million infected personal computers from control of cyber crooks in its most successful digital crime-busting operation, which interrupted service at an Internet-services firm last week.
The world’s largest software maker has also identified at least another 4.7 million infected machines, though many are likely still controlled by cyber fraudsters, Microsoft’s cybercrime-fighting Digital Crimes Unit said on Thursday.
India, followed by Pakistan, Egypt, Brazil, Algeria and Mexico have the largest number of infected machines, in the first high-profile case involving malware developed outside Eastern Europe.
Richard Domingues Boscovich, assistant general counsel of the unit, said Microsoft would quickly provide government authorities and Internet service providers around the world with the IP addresses of infected machines so they can help users remove the viruses. The operation is the most successful of the 10 launched to date by Microsoft’s Digital Crimes Unit, based on the number of infected machines identified,.
The operation, which began on June 30 under a US federal court order, targeted malicious software known as Bladabindi and Jenxcus, which Microsoft said work in similar ways and were written and distributed by developers in Kuwait and Algeria.
