This is a quick post to follow up on the recent What is gumblar? post. Its been the most popular blog post so far and is getting a steady stream of traffic from the search engines. I came across an article by the Google Security Team on their Google Online Security Blog that I thought was worth mentioning due to its relevance to the Gumblar post.

In the Blog post the Google security team provide some statistics on sites that distribute malware. They explain how they have automated systems in place to scan their index looking for potentially dangerous sites. Any sites deemed to be potentially dangerous are flagged as such in their search results.

The Blog post also includes a chart that shows the top 10 malware sites. They determined the top 10 by looking at the number of compromised web sites that referenced the malware site. The chart shows the Gumblar.cn has approximately 60,000 compromised sites. The chart has arrows to indicate when the domains were first flagged as being potentially dangerous. From looking at this start date you can see how Gumblar.cn really exploded onto the scene with the number of compromised sites growing rapidly.

You can find the complete article on the Google Online Security Blog.
