In another report published by Confiant, the malicious ads increased from Q2 to Q3. The Q3 attacks are targeting desktop computers, mainly running Windows and they are attacking users mainly in Italy, Spain, and Scandinavia.

The Windows operating is the most used one, it’s popularity let malware authors invest more time and resource to develop a more sophisticated malware. Wannacry is an example of it.

We can’t assume Linux OS is the most secured one, nowadays attackers targeting Linux servers also to install various malware, most particularly coin miner scripts.

With Q3 three different variations of ads observed

Malicious ad – Ads with Javascript that force redirection to another website.
In-Banner Video (IBV) ad – Serving Video ads with banner placements.
Low-Quality ad – Noisy ads based on user location

Researchers believe that “nearly 1 in every 250 impressions is dangerous or disruptive to the end-user, which equates to 4 billion malicious or disruptive impressions a month across the entire industry.”
