Microsoft Seizes Botnet Servers

Microsoft Corp scored a win in efforts to fight online banking fraud, saying it had seized several servers used to steal login names and passwords, disrupting some of the world’s most sophisticated cybercrime rings.

The software giant said on Monday that its cybercrime investigation group also took legal and technical actions to fight notorious criminals who infect computers with a prevalent malicious software known as Zeus.

By recruiting computers into networks called botnets, Zeus logs the online activity of infected machines, providing criminals with credentials to access financial accounts.

“We’ve disrupted a critical source of money-making for digital fraudsters and cyber thieves, while gaining important information to help identify those responsible and better protect victims,” said Richard Boscovich, senior attorney for the Microsoft Digital Crimes Unit, which handled the investigation in collaboration with the financial industry.

Microsoft’s Digital Crimes Unit is worldwide team of investigators, lawyers, analysts and other specialists who fight cybercrime. A year ago they helped U.S. authorities take down a botnet known as Rustock that had been one of the biggest producers of spam e-mail. Some security experts estimated that in its heyday Rustock was responsible for half the spam in junk email bins.
