OREANDA-NEWS. April 20, 2015. International law-enforcement authorities at Interpol teamed up with Microsoft, the Cyber Defense Institute in Japan, and security firms Kaspersky Lab and Trend Micro to take down a second major botnet last week, in a coordinated effort to disrupt the criminal operation, the Interpol Global Complex for Innovation (IGCI) said in a statement on April 13.

The botnet, known as Simda.AT, has infected more than 770,000 systems in the past six months, attempting to redirect Internet traffic and download additional malware to compromised computers. Microsoft's Digital Crime Unit (DCU) alerted law enforcement to the botnet following a dramatic increase in activity, IGCI stated. The groups detected approximately 90,000 newly infected systems in the United States in the first two months of this year, according the IGCI.
