How to TestĪs mentioned above, this type of attack is often designed to allow an attacker to induce users’ actions on the target site, even if anti-CSRF tokens are being used. Consequently, some of the anti-CSRF protections deployed by the developers to protect the web page from CSRF attacks could be bypassed. The power of this method is that the actions performed by the victim are originated from the hidden but authentic target web page. Using the hidden page, an attacker can deceive users into performing actions they never intended to perform through the positioning of the hidden elements in the web page.įigure 4.11.9-2: Masked inline frame illustration The victim surfs the attacker’s web page with the intention of interacting with the visible user interface, but is inadvertently performing actions on the hidden page. Like other attacks, a common prerequisite is that the victim is authenticated against the attacker’s target website.įigure 4.11.9-1: Clickjacking inline frame illustration
Once this is done, an attacker may induce the victim to interact with the web page by other means (through, for example, social engineering). To carry out this attack, an attacker creates a seemingly-harmless web page that loads the target application through the use of an inline frame (concealed with CSS code). This is a client side security issue that affects a variety of browsers and platforms.
The term clickjacking was coined by Jeremiah Grossman and Robert Hansen in 2008.Ī clickjacking attack uses seemingly-harmless features of HTML and JavaScript to force the victim to perform undesired actions, such as clicking an invisible button that performs an unintended operation. This type of attack, either alone or in conjunction with other attacks, could potentially send unauthorized commands or reveal confidential information while the victim is interacting with seemingly-harmless web pages. Clickjacking, a subset of UI redressing, is a malicious technique whereby a web user is deceived into interacting (in most cases by clicking) with something other than what the user believes they are interacting with.
