Scammers have used the site visitors from an grownup web site to generate clicks on Google Advert banners, netting them big returns, specialists have revealed.

Researchers from Malwarebytes, which first noticed the marketing campaign, revealed how somebody created an advert marketing campaign on one of many main grownup advert networks and used the “popunder” advert format. 

It’s primarily a pop-up, but it surely goes underneath the lively browser window. That manner, the adverts displayed can solely be seen after the person closes, or minimizes, the browser. 

“Clear” adverts on grownup websites

Then, they created a faux information web site, whose content material is scraped from different content material websites. The articles revealed on this web site embody varied tutorials, guides, and comparable. Being “clear” (no grownup content material, playing, or comparable), the positioning was allowed to point out adverts from the Google Advertisements community. 

Then, they overlaid the positioning with an iframe exhibiting content material from the TXXX grownup web site. 

In different phrases, when a customer from an grownup web site closes their browser, they’ll see a popunder promoting TXXX, which additionally appears respectable, given the context. Nevertheless, ought to the customer attempt to click on on any of the movies, they’ll truly be clicking on the advert and thus generate revenue for the fraudsters.

Even when they don’t click on on the advert, the straightforward undeniable fact that it loaded generates income for the fraudsters, as advert networks additionally pay out for advert impressions. That’s why the faux information web site, and the adverts on it, get refreshed each 9 seconds.

Malwarebytes says popunders are fairly cost-efficient, as the typical price per thousand impressions (CMP) can go as little as $0.05, and provided that the site visitors on grownup websites is very large, the menace actor behind the scheme managed to generate an enormous quantity in earnings.

Per Malwarebytes’ estimates, the marketing campaign, which has now been terminated, generated 76 million advert impressions monthly which, with a CPM of $3.50, brings earnings as much as $276,000 a month.

The menace actor’s identification is unknown, however apparently, they’re Russian.
