The distribution of Koobface through Google Blogspot continues.  Detailed information documented by Jorge Mieres of Pistus Malware Intelligence can be found here. The quick version is 39 domains using Googles Blogspot service redirect unsuspecting users to other domains which deliver Koobface using social engineering tactics.

The domains being used for delivery starting showing up in early December and can be found here. A majority of the 350+ domains are being hosted in the United States using GoDaddys web hosting service.The domains are geographically dispersed around the globe using a variety of hosting providers which helps the attackers ensure a slow takedown.
