The list of monetization tactics a cybercriminal can take advantage of, once they manage to hijack a huge portion of Web traffic, is virtually limitless and is entirely based on his experience within the cybercrime ecosystem.
Through the utilization of blackhat SEO (search engine optimization), RFI (Remote File Inclusion), DNS cache poisoning, or direct impersonation of popular brands in spam/phishing campaigns tactics, on a daily basis, traffic is sold and resold for achieving a customer’s or a seller’s fraudulent/malicious objectives, and is then most commonly converted to malware-infected hosts.
In this post, I’ll profile two cybercrime-friendly iFrame traffic exchanges, with the second ‘vertically integrating’ by also offering spamming services, as well as services violating YouTube’s ToS (Terms of Service) such as likes, comments, views, favorites and subscribers on demand, with an emphasis on the most common ways through which a potential cybercriminal can abuse any such traffic exchange network.

Redirectors are a popular tactic used by cybercriminal on their way to trick Web filtering solutions. And just as we’ve seen in virtually ever segment of the underground marketplace, demand always meets supply.
A newly launched, DIY ‘redirectors’ generating service, aims to make it easier for cybercriminals to hide the true intentions of their campaign through the use of ‘bulletproof redirector domains’. Let’s take a peek inside the cybercriminal’s interface, list all the currently active redirectors, as well as the actual pseudo-randomly generated redirection URLs.

Operating in the open since 2009, a bulletproof hosting provider continues offering services for white, grey, and black projects, as they like to describe them, and has been directly contributing to the epidemic growth of cybercrime to the present day through its cybercriminal-friendly services.
From Traffic Distribution Systems (TDS), to doorways, pharmaceutical scams, spam domains and warez, the provider is also utilizing basic marketing concepts like, for instance, promotions through coupon codes in an attempt to attract more customers.

How would a cybercriminal differentiate his unique value proposition (UVP) in order to attract new customers wanting to purchase commoditized underground market items like, for instance, harvested and segmented email databases? He’d impress them with comprehensiveness and ‘vertically integrated’ products and services. At least that’s what the cybercriminals behind the cybercrime-friendly market proposition I’m about to profile in this post are doing.
Tens of millions of harvested and segmented email databases, spam-ready bulletproof SMTP servers and DIY spamming tools, this one-stop-shop for novice spammers is also a great example of an OPSEC-unaware vendor who’s not only accepting Western Union/Money Gray payments, but also, has actually included his SWIFT wire transfer bank account details.

Throughout the last couple of years, the persistent demand for geolocated traffic coming from both legitimate traffic exchanges or purely malicious ones — think traffic acquisition through illegally embedded iFrames — has been contributing to the growing market segment where traffic is bought, sold and re-sold, for the sole purpose of monetizing it through illegal means.
The ultimately objective? Expose users visiting compromised, or blackhat SEO-friendly automatically generated sites with bogus content, to fraudulent or malicious content in the form of impersonations of legitimate Web sites seeking accounting data, or client-side exploits silently served in an attempt to have an undetected piece of malware dropped on their hosts.
A recently spotted cybercrime-friendly underground traffic exchange service empowers cybercriminals with advanced targeting capabilities on per browser version basis, applies QA (Quality Assurance) to check their fraudulent/malicious domains against the most popular community/commercial based URL black lists, and ‘naturally’ we found evidence that it’s already been used to serve client-side exploits to unsuspecting users.
