The Koobface Gang Mixing Social Engineering Vectors

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 :

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