Security Incentives and Advertising Fraud
Details are in the article, but here’s the general idea:
Let’s follow the flow of the users:
- Scammer buys user traffic from PornoXo.com and sends it to HQTubeVideos.
- HQTubeVideos loads, in invisible iframes, some parked domains with innocent-sounding names (relaxhealth.com, etc).
- In the parked domains, ad networks serve display and PPC ads.
- The click-fraud sites click on the ads that appear within the parked domains.
- The legitimate publishers gets invisible/fraudulent traffic through the (fraudulently) clicked ads from parked domains.
- Brand advertisers place their ad on the websites of the legitimate publishers, which in reality appear within the (invisible) iframe of HQTubeVideos.
- AdSafe detects the attempted placement within the porn website, and prevents the ads of the brand publisher from appearing in the legitimate website, which is hosted within the invisible frame of the porn site.
Notice how nicely orchestrated is the whole scheme: The parked domains “launder” the porn traffic. The ad networks place the ads in some legitimately-sounding parked domains, not in a porn site. The publishers get traffic from innocent domains such as RelaxHealth, not from porn sites. The porn site loads a variety of publishers, distributing the fraud across many publishers and many advertisers.
The most clever part of this is that it makes use of the natural externalities of the Internet.
And now let’s see who has the incentives to fight this. It is fraud, right? But I think it is well-executed type of fraud. It targets and defrauds the player that has the least incentives to fight the scam.
Who is affected? Let’s follow the money:
- The big brand advertisers (Continental, Coca Cola, Verizon, Vonage,…) pay the publishers and the ad networks for running their campaigns.
- The publishers pay the ad network and the scammer for the fraudulent clicks.
- The scammer pays PornoXo and TrafficHolder for the traffic.
The ad networks see clicks on their ads, they get paid, so not much to worry about. They would worry if their advertisers were not happy. But here we have a piece of genius:
The scammer did not target sites that would measure conversions or cost-per-acquisition. Instead, the scammer was targeting mainly sites that sell pay-per-impression ads and video ads. If the publishers display CPM ads paid by impression, any traffic is good, all impressions count. It is not an accident that the scammer targets publishers with video content, and plenty of pay-per-impression video ads. The publishers have no reason to worry if they get traffic and the cost-per-visit is low.
Effectively, the only one hurt in this chain are the big brand advertisers, who feed the rest of the advertising chain.
Do the big brands care about this type of fraud? Yes and no, but not really deeply. Yes, they pay for some “invisible impressions”. But this is a marketing campaign. In any case, not all marketing attempts are successful. Do all readers of Economist look at the printed ads? Hardly. Do all web users pay attention to the banner ads? I do not think so. Invisible ads are just one of the things that make advertising a little bit more expensive and harder. Consider it part of the cost of doing business. In any case, compared to the overall marketing budget of these behemoths, the cost of such fraud is peanuts.
The big brands do not want their brand to be hurt. If the ads do not appear in places inappropriate for the brand, things are fine. Fighting the fraud publicly? This will just associate the brand with fraud. No marketing department wants that.
