Dissecting a Swine Flu Black SEO Campaign

Remember the Ukrainian group of cyber criminals that was responsible for last week's massive blackhat SEO campaign that was serving scareware, followed by the timely hijacking of Mickeyy worm keywords a week earlier to once again serve rogue security software?

They are back with new blackhat SEO farms which they continue monetizing through rogue security software. Time to dissect their latest campaign and expose their malicious practices.

Once having most of their previous domains blacklisted/shut down, the group naturally introduced new ones, and changed the search engine optimization theme to swine flu, in between a variation of their previous one relying on catchy titles such as USA News; BBC News; CNN News as well as Hottest info!; HOT NEWS; Official Website and Official Site.

Upon visiting the site, an obfuscated iFrame statically hosted on all of the participating domains in the form of 2qnews.07x .net/images/menu.js redirects the user to sexerotika2009 .ru/admin/red/en.php (74.54.176.50; Email: rebsdtis@land.ru). Are you noticing the directory structure similarities? Appreciate my rhetoric, it's last month's blackhat SEO gang with a new portfolio of domains.

What follows is the usual referrer check : "var ref,i,is_se=0; var se = new Array("google.","msn.","yahoo.","comcast.","aol.");" from where the user is redirected to liveavantbrowser2 .cn/go.php?id=2022&key=4c69e59ac&p=1 (83.133.123.140) acting as central redirection point to the typosquatted portfolio of rogue security software domains.

The original scareware domain vrusstatuscheck .com/1/?id=2022&smersh=a9fd94859&back=%3DjQ51TT1MUQMMI%3DN - (69.4.230.204; 38.99.170.209; 78.47.172.66; 78.47.91.153; 94.76.212.239; 94.102.48.28) is exposing the rest of the scareware (detection rate) portfolio with the following domains parked at these IPs:
