Will visiting infect your computer?


I’ve coved Blinkx before in connection with unwanted software installations. They recently came to my attention again.. and not in a good way.

Let’s start with the Google Safe Browsing Diagnostics for

Next steps:

Not listed as suspicious? But 92 out of 1007 pages attempt to install malware! That’s 9.1% of all pages on the site that Google checked! But people who visit Blinkx don’t just visit one page. According to Alexa, the average visitor views 3.88 pages on the site. It also notes that is the 1994th most popular site worldwide.

We can work out the probability of infection using the data, it’s is (1-(1-(92/1007))^3.88)) which equates to a 31% possibility that the average visitor will be exposed to malware. OK, that’s assuming that the data is accurate, and since I know for a fact there are more than 1007 pages on Blinkx and that Alexa data has its critics.. well, take that figure as being indicative rather than 100% accurate. reports that over 5 million US visitors look at the site per month. There are doubtless millions more visiting this site. So exactly how many people have been infected while visiting

My suggestions? If you are an IT administrator, I think you want to seriously consider if allowing your users to visit is in line with your corporate governance strategy..
