Here at the Microsoft Malware Protection Center (MMPC) we look for ways to share the valuable data, insights and expertise that we have with our customers on a regular basis. We just released the sixth volume of our Microsoft Security Intelligence Report (SIR). The SIR shares the conclusions drawn by our research team using data gathered from hundreds of millions of computers worldwide and some of the busiest services on the internet.
A very clear trend we saw in the second half of 2008 was the rise in prevalence of rogue security software (software which poses as anti-malware or anti-spyware protection but in reality does little or nothing, and may even be malware!) The data also indicated that the number one threat we saw worldwide was Win32/Renos, a family of trojan downloaders and droppers that is used to distribute rogue security software – in the second half of 2008 we saw this threat increase in prevalence by 66.6%! We also saw a number of other rogue security software families increase in prevalence around the world, in different languages – be careful out there! Get your software from a trusted source. You've heard it before. It's sound advice we want to pass along.
Here are a couple of other key findings from the report:
Here are some resources that Microsoft has created to help you protect yourself from these threats:
