Even more nasty malware in the news, a new Trojan that exploits Google's Adsense is in the wild now. It is able to falsify search results that are turned up by Adsense, which is used by many sites. Once infected, ads look legit, aside from perhaps the titles, but are actually filtered by the trojan to produce whatever it wants. The article explains.
”The working of the Ad has a specific procedure. Wherein when the ad is clicked it forwards the user to 3 different sites one after another. What follows next is that the user finally lands himself to a page having a bevy of ads and links to more ads. Through this malicious program advertisers and publishers are the ones who are being deprived of their revenue.”
Google AdLinks are unaffected, and it's important to note that this is a user end infection, not a server compromise... but with the high use of Google and how often people take searching for granted, it's good to be careful.
