By Dancho Danchev

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.

By Dancho Danchev

Among the most common misconceptions about the way a novice cybercriminal would approach his potential victims has to do with the practice of having him looking for a ‘seed’ population to infect, so that he can then use the initially infected users as platform to scale his campaign. In reality though, that used to be the case for cybercriminals, years ago, when managed cybercrime-as-a-service types of underground market propositions were just beginning to materialize.

In 2013, the only thing a novice cybercriminal wanting to gain access to thousands of PCs located in a specific country has to do is to make a modest investment in the (managed) process of obtaining it. Let’s take a peek at one of the most recently launched such services.
