Abstract
There are disclosed devices, system and methods for detecting cross-origin malicious code existing in an internet advertisement (ad) requested by a published webpage viewed by a user. First, receipt of the ad is detected, where that ad includes cross-origin malicious code that causes a browser cross-origin unwanted action without user action. The ad is then executed in a browser sandbox that displays the cross-origin malicious code and intercepts the cross-origin unwanted action. When a cross-origin security error results from this execution, the cross-origin malicious code is discontinued and the cross-origin unwanted action is intercepted.
