"Contrary to the normal Google ads, which have some correlation to the content on the Web page, these malicious ads had no content that was remotely similar to the pages to which they had been attached," Techshout quotes Bangera as saying. "Most of the ads were about gambling or adult content, which are banned categories in Google AdSense, clearly indicating a suspicious origin." According to Techshout, when users click on the fake AdSense ads, they boot the user to three successive sites. The user is eventually dumped onto a page with a slew of ads and links to more ads.
