What has changed since the last time? The number and importance of the sites has increased, Google is to what looks like filtering the search results despite that the malicious parties may have successfully injected the IFRAMEs already, thus trying to undermine the campaign, new malware and fake codecs are introduced under new domain names, and a couple of newly introduced domains within the IFRAMES themselves.
Keep it Simple Stupid for the sake efficiency is what makes the campaign relatively easy to track once you understand the importance of hot leads, and real-time assessments for the purpose of setting the foundation for someone else's upcoming piece of the puzzle in an OSINT manner. The main IPs within the IFRAMES acting as redirection points to the newly introduced rogue software and malware, remain the same, and are still active. The very latest high profile sites successfully injected with IFRAMES forwarding to the rogue security software and Zlob malware variants :

For the time being, Google is actively filtering the results, in fact removing the cached pages on number of domains when I last checked, the practice makes it both difficult to assess how many and which sites are actually affected, and of course, undermining the SEO poisoning, as without it the input validation and injecting the IFRAMEs would have never been able to attract traffic at the first place.
The attack is now continuing, starting two weeks ago, the main IPs behind the IFRAMES are still active, new pieces of malware and rogue software is introduced hosting for which is still courtesy of the RBN, and we're definitely going to see many other sites with high page ranks targeted by a single massive SEO poisoning in a combination with IFRAME injections. Which site is next? Let's hope not yours, as if you don't take care of your web application vulnerabilities, someone else will.
