While this helps protect against most browser based threats, one area that is commonly exploited is ad-injection. Unlike the bulk of a page’s content, ads tend to be loaded from an external ad server or Content Delivery network (CDN).

Attackers have found a way to insert malware into the advertising code, which in some cases can circumvent the web page’s security and serve malicious code to the visitor.

In an effort to combat ad-injection malware, Google’s Safe Browsing team announced that when Chrome detects a possible ad-injection on a site that it will serve its famous “red screen” advising the user that the site is potentially unsafe to visit.
