Massive Blackhat SEO Campaign Serving Scareware

Over the past couple of days, I've been monitoring yet another massive blackhat SEO campaign consisting of the typical hundreds of thousands of already crawled bogus pages serving scareware/fake security software.

Later on Google detected the campaign and removed all the blackhat SEO farms from its index, which during the time of assessment were close to a hundred domains with hundreds of subdomains, and thousands of pages within.

And despite that the abuse notifications for some of the central redirection domains proved effective,  it took the cybercriminals approximately 24 hours to catch up, and once again start hijacking search queries, in a combination of scareware, and pay per click redirections.

It's worth pointing out that this very latest campaign is directly related to last's week's keywords hijacking blackhat SEO campaign, with both campaigns relying on identical redirection domains, and serving the same malware. Who's behind these search engine poisoning attacks? An Ukranian gang monetizing the hijacked traffic through the usual channels - scareware and reselling of the anticipated traffic.

The first stage of the campaign was relying on mainstream media titles within its pages such as USA News; BBC News; CNN News as well as Hottest info!; HOT NEWS; Official Website and Official Site, thereby making it fairly easy to expose their portfolio of domains.

Interestingly, the cybercriminals appear to have detected the activity -- certain traffic management kits can log attempts of wandering around -- and removed the titles, which combined with the typical referrer checking made the campaign a bit more evasive :

""var ref,i,is_se=0; var se = new Array("google.","msn.","yahoo.","comcast.","aol.","dead"); if(document.referrer)ref=document.referrer; else ref=""; for(i=0;i<5;i++""

Once the user visits any of the domains within the portfolio, with a referrer check confirming he used a search engine to do so, two javascripts load, one dynamically redirecting to the portfolio of fake security software, and the other logging the visit using an Ukrainian web site counter service (c.hit.ua/hit?i=6058&g=0&x=2&s=1&c=1&t=420&w=1024&h=768&d=24&0.5505934176708958&r=&u=http%3A//13news.hobby-site.com/counter.js')


The most recent list of of domains on popular DNS services is as follows. Sub-domains within are excluded since there are several hundred currently active per domain:
