In a clickjacking attack, a malicious static HTML documents to complex, full-fledged applica- page is constructed such that it tricks victims into clicking tions containing hundreds of dynamically generated pages. on an element of a different page that is only barely (or not The combined use of client and server-side scripting allows at all) visible. By stealing the victim’s clicks, an attacker developers to provide highly sophisticated user interfaces could force the user to perform an unintended action that is with the look-and-feel and functionalities that were previ- advantageous for the attacker (e.g., initiate an online money ously only reserved to traditional desktop applications.

Although clickjacking has been the subject the same time, many web applications have evolved into of many discussions and alarming reports, it is currently mesh-ups and aggregation sites that are dynamically con- unclear to what extent clickjacking is being used by attackers structed by combining together content and functionalities in the wild, and how significant the attack is for the security provided by different sources.
