It's the Facebook message that came from one of your infected friends pointing you to an on purposely created bogus Bloglines blog serving fake YouTube video window, that I have in mind. The Koobface gang has been mixing social engineering vectors by taking the potential victim on a walk through legitimate services in order to have them infected without using any client-side vulnerabilities.For instance, this bogus Bloglines account (bloglines .com/blog/Youtubeforbiddenvideo) has attracted over 150 unique visitors already, part of Koobface's Hi5 spreading campaign (catshof .com/go/hi5.php). The domain is parked at the very same IP that the rest of the central redirection ones in all of Koobface's campaigns are - 58.241.255.37.
Interestingly, since underground multitasking is becoming a rather common practice, the bogus blog has also been advertised within a blackhat SEO farm using the following blogs, currently linking to several hundred bogus Google Groups accounts :bloglines .com/blog/gillehuxeda

Abusing legitimate services may indeed get more attention in the upcoming year, following their interest in the practice from the last quarter.
