Devcon Analysts countedthat most often targets for malicious ads are Windows users. They are followed by users of Chrome OS, and Linux is the least attacked.
Statistics were compiled on the basis of data collected by the company's internal tools. As it turned out, 61% of the malicious advertisements that researchers observed from July 11 to November 22, 2019 were targeted at Windows users.
Experts explain that it is not necessary to be surprised: given that a huge share of the OS market belongs to Windows, it is not surprising that most of the malware over the past 30 years was intended specifically for Windows.
Nevertheless, Chrome OS takes the second place in the list, which pretty surprised experts. Over the past four months, many malicious advertising campaigns have targeted the Google operating system: 22% of malicious ads targeted Chrome OS users, and this is more than macOS (10.5%), iOS (3.2%), Android (2 , 1%) and iPadOS (0.8%).
At the same time, the least attacks were aimed at Linux – only 0.3% of the total number of malicious ads. But this is also not surprising, since most Linux systems are used as servers.
Similar report, also dedicated to malicious advertising, was published by Confiant. Researchers examined over 120 billion impressions of advertisements published in the third quarter of 2019 (July 1 to September 30, 2019) in 75 advertising networks.
It was found that almost 60% of all malicious ads seen in the third quarter of 2019 were published on three unnamed advertising platforms. “The most worrying thing is that only one supplier was responsible for 30% of the impressions of malicious ads,” analysts say, but do not disclose the name of this company.
According to researchers, the detection of malicious advertising campaigns on their platforms should not be difficult for companies, since such activity is usually quite “loud” and affects 13.84% of all advertising displays on the platform.
