Necurs Malware Infects over 83,000 Machines in November 2012, Microsoft Says

Experst have thoroughly analyzed this dangerous threat

Necurs is a piece of malware that has been seen infecting tens of thousands of machines over the past period. According to experts from Microsoft’s Malware Protection Center, it has been spotted on 83,427 unique computers in November alone.

Researchers reveal the fact that Necurs is usually distributed via websites that host the BlackHole exploit kit. Once the threat finds itself on a computer, it downloads additional malicious elements, it disables security applications, and it hides its components.

Furthermore, the malware also allows its masterminds to gain complete control over the infected device through its backdoor functionality.

Unfortunately, this is not the only damage that Necurs is capable of causing. It can also send spam and install pieces of scareware.

Interestingly, experts reveal that the malware might be capable even of disabling Microsoft Security Essentials’ real time protection.

Microsoft researchers have published a technical analysis of how Necurs manages to accomplish all these tasks.
