Google ads: Trojans spread across Doubleclick advertising banners

Almost a month, Google’s advertising ads networks Doubleclick and Zedo Trojans have spread over their banners. Concerned were, among other things, well-known websites such as last.fm and the pages of the Times of Israel and the Jerusalem Post.


The attacks were now discovered by the antivirus manufacturer Malwarebytes. Zedo and Google's Doubleclick distribution network are making sure that other popular websites are affected too.


Google has confirmed the problem against the US portal The Verge and has now removed the infected advertising banners. The most important target system for the malware Trojan.Agent.BPEN from the trojan family Zemot was Windows XP, but the Trojan can also attack all other Windows systems if they are inadequately protected. In particular, computers in the US, Israel, Canada, the UK and France were reported as malwarebytes.

Zemot is discovered by all current protection programs and can only be deployed on insufficiently protected computers. The scale of misuse of infected computers includes all known damage pictures from the disposal of personal data through click fraud up to the switching of botnets, because the malware has the ability to reload any modules over the web and update itself.


For cybercriminals, the injection of malware through ad banners is tempting, as these often appear on popular websites that users trust.
