The top networks, such as Google Display Network or Yahoo! Bing Network Contextual Ads, have more resources and expertise.

Uncovering the tiny percentage that are harmful is a major task. Major ad networks serve billions of ads a day. Even if they knew, they could not stop the ads from showing without removing the network’s ads completely – and that may kill a site's only revenue stream. So websites can show ads that harm visitors without realizing it. The networks determine which ads are shown, and the ads change every time a page loads. The sites dedicate space to show the ads, and the network pays based on the number of impressions or clicks.īut other than choosing where to show ads on their sites, the site owners have no control over the ads' content. Without ad revenue, many websites would not exist.īy joining an ad network, websites can easily turn site traffic into revenue. The internet economy runs on advertising. Unfortunately, this also makes it easier for attackers to slip in.Īll of this gives criminals (and legitimate companies) a fast and easy way to spread their message. By removing barriers, the networks can sell more ad space. They can target the ads by site topic, region, and even web browser.Īlso, ad networks make buying and uploading ads as fast and easy as possible.

Internet Explorer (IE), Java Runtime Environment (JRE), and other applications have been major targets in the past, and we can expect the cycle to continue. Several zero-day exploits for Flash have recently been discovered in online ads, and there have even been calls to “get rid” of Flash by some.Īs you can see in this chart from Bromium’s report, Flash is having its turn in a long cycle of favorite applications to exploit:Ĭriminals change tactics constantly.
