A Portfolio of Fake Video Codecs

Shall we expose a huge domains portfolio of fake/rogue video codecs hosting the same Zlob variant on each and every of the domains, thereby acting as a great example of what malicious economies of scale means? But of course. As I've pointed out in a previous post, on the tactical warfare front the output of a malicious IFRAME campaign is often neglected from the perspective of lacking the two/three layered IFRAME-ing and redirection that the malicious parties usually implement at the beginning of the campaign. Basically, the over twenty fake video codecs domains are hosting the same binary in the form of a Zlob malware downloader, infrastructure courtesy of the RBN's used ATRIVO ( Currently active domains hosting the" DVDAccess codec", namely a Zlob malware variant :

DVDaccess's pitch : "DVDaccess is a multimedia software that allowa access to Windows collection of multimedia drivers and integrates with any application using DirectShow and Microsoft Video for Windows. DVDaccess will highly increase quality of video files you play. DVDaccess enhances your music listening experience by improving the sound quality of video files sound, MP3, internet radio, Windows Media and other music files. Renew stereo depth, add 3D surround sound, restore sound clarity, boost your audio levels, and produce deep, rich bass sounds."

Why are the malicious parties so KISS oriented at the end of every campaign, compared to the complexity and tactical warfare tricking automated malware harvesting approaches within the beginning of the campaign? Because they're not even considering the possibility of proactively detecting the output of the many other malware campaigns to come, which will inevitable be ending up to these very same domains serving a single Zlob variant. Just like the recent massive IFRAME attacks, where in between the live exploit URLs and rogue security software, the end users were redirected to DVDaccess as well. In fact, the massive IFRAME attack campaign was, and continues to redirect to one of the domains in the portfolio I've just provided you with.
