Is Clickjacking Cross Frame Scripting?


Heather Bennett

Clickjacking is a type of cyber attack that tricks users into clicking on a malicious element, unknowingly performing an action they did not intend. This technique is often used to exploit vulnerabilities in web browsers and gain unauthorized access to sensitive information.

Is Clickjacking Cross Frame Scripting?

Clickjacking and cross-frame scripting are two different concepts, although they are related in terms of the impact they can have on web security. Let’s take a closer look at each of these techniques.


Clickjacking, also known as UI redressing, is a method used by attackers to deceive users into clicking on hidden or disguised elements on a webpage. The attacker overlays an invisible layer or transparent frame over legitimate content, making it appear harmless and enticing users to interact with it. The hidden element could be a button, link, video, or any other interactive element.

The primary goal of clickjacking attacks is to trick users into performing actions such as sharing sensitive information, granting permissions, or executing malicious code. These actions are usually performed without the user’s knowledge or consent.

Cross Frame Scripting

Cross-frame scripting (XFS) refers to the ability of JavaScript code running in one frame or window to access the content of another frame or window within the same browser session. This technique can be used for both legitimate purposes and malicious activities.

Legitimate uses of cross-frame scripting include embedding content from different domains or securely communicating between frames within the same origin. However, when used maliciously, XFS can lead to security vulnerabilities like data leakage and unauthorized access to sensitive information.

The Relationship Between Clickjacking and Cross Frame Scripting

While clickjacking does not directly involve cross-frame scripting, attackers often use this technique in combination with other methods like XFS to achieve their goals. For example, an attacker may use cross-frame scripting to load a clickjacking overlay on top of a legitimate website, making it difficult for users to differentiate between the genuine content and the malicious element.

By combining clickjacking with cross-frame scripting, attackers can deceive users into clicking on hidden elements while also gaining access to sensitive information or performing actions on behalf of the user. This combination enhances the effectiveness and impact of the attack.

Protecting Against Clickjacking and Cross Frame Scripting

To protect against clickjacking attacks, website owners can implement security measures such as frame-busting scripts, X-Frame-Options headers, and Content Security Policy (CSP) directives. These measures help prevent attackers from overlaying their malicious content onto legitimate websites.

To mitigate the risks associated with cross-frame scripting, web developers should ensure that their applications have proper input validation and output encoding mechanisms in place. Additionally, implementing appropriate access controls and strict origin policies can help prevent unauthorized access to sensitive information across frames.

In conclusion

While clickjacking and cross-frame scripting are distinct techniques, they are often used together by attackers to exploit vulnerabilities in web applications. Understanding these concepts and implementing appropriate security measures is crucial for protecting user data and maintaining the integrity of web-based systems.
