According to statistics shared by the Internet company DevCon last week, malicious advertising attacks are mainly targeted at windows platforms.Based on data collected by internal tools from July 11 to November 22, 2019, 61% of malicious advertising programs are targeted at Windows users, the company said.

But there's also a surprising finding in this malicious ad report that attacks on the Chrome OS platform are growing at an alarming rate in the past four months. DevCon said that 22% of the malicious ads they observed were targeted at Google's emerging operating system, surpassing Mac OS (10.5%), IOS (3.2%), Android (2.1%) andIPadOS（0.8％）。
DevCon said that GNU / Linux was the platform with the least attacks, accounting for only 0.3% of all malicious advertisements. This is not surprising because most Linux systems are used as servers.
Confiant, an advertising security company, last week published another report that looked at the entire ecosystem and the sources of these malicious ads. Confiant said it analyzed 120 billion advertising impressions released in the third quarter of 2019 (from July 1 to September 30, 2019) through 75 ad networks, known as SSPs or supplier platforms.
Every quarter, every advertising platform is abused by malicious ads, the company said. However, although some ad networks fight against abuse and take appropriate security measures, some platforms often seem to tolerate malicious advertisers. Confiant said it found that nearly 60% of all malicious advertising recorded in the third quarter of 2019 came from only three advertising platforms. "The most shocking thing is that an SSP is responsible for 30% of the malicious advertising," confiant said However, the company did not publish the names of the three advertising platforms.
