Clickjacking (user-interface or UI redressing and IFRAME overlay)

Clickjacking is a type of attack that tricks a user into clicking on a button or link on a page other than the one they intended to. This can be done by overlaying a malicious page on top of a legitimate page, using a transparent IFRAME, or by hiding the malicious link within a page. Clickjacking can be used to perform a variety of malicious actions, such as stealing login credentials, downloading malware, or redirecting a user to a malicious website.

Clickjacking is also sometimes referred to as "UI redressing" or "IFRAME overlay" attacks.

What is UI redressing?

UI redressing is a type of attack that occurs when a malicious actor tricks a user into clicking on a button or link that they believe will perform a harmless action, but instead performs a malicious action. This can occur when the button or link is not properly labeled, or when the user is not given enough information about what will happen when they click on it. UI redressing can be used to trick a user into clicking on a link that will take them to a malicious website, or into providing personal information to a malicious actor. UI redressing can also be used to trick a user into downloading and installing malware.

What is an example of clickjacking defenses? An example of a clickjacking defense is to use a web browser plugin that detects and blocks clickjacking attacks. Another defense is to ensure that all iframes on a website are from the same origin, so that an attacker cannot use a foreign iframe to overlay content on the page. Finally, websites can use frame-busting JavaScript to prevent their content from being embedded in an iframe.

Is clickjacking a serious vulnerability?

Yes, clickjacking is a serious vulnerability that can be exploited by attackers to gain control of a user's web browser. Clickjacking occurs when an attacker tricks a user into clicking on a malicious link or button that is embedded in a web page. This can allow the attacker to perform various actions on the user's behalf, such as stealing sensitive information or redirecting the user to a malicious website. Clickjacking can be used to attack any web-based application, and is particularly dangerous when combined with other attacks, such as phishing or malware.

What causes clickjacking?

There are a few different ways that clickjacking can occur, but they all involve tricking a user into clicking on something that they didn't intend to. This can be done by embedding an element from another website in a frame on the page, by using a transparent overlay, or by hiding the element in a pop-up window. Clickjacking can also occur on mobile devices, where an attacker can use a malicious app to intercept clicks intended for another app.

One common way that clickjacking is used is to trick users into clicking on a button or link that will like or share a piece of content on social media. The user thinks they are just clicking on a normal button, but in reality they are liking or sharing the content without knowing it. This can be used to spread malicious content or to simply inflate the number of likes or shares on a piece of content.

Another common way that clickjacking is used is to trick users into clicking on a button or link that will make a purchase or sign up for a service. The user thinks they are just clicking on a normal button, but in reality they are making a purchase or signing up for a service without knowing it. This can be used to trick users into making unwanted purchases or signing up for unwanted services.

Clickjacking can also be used to trick users into clicking on a button or link that will perform a dangerous action, such as downloading malware or opening a pop-

What is a iframe?

An iframe is an HTML document embedded inside another HTML document on a web page. The iframe HTML element is often used to embed content from another website, such as a video from YouTube. Iframes are sometimes used to display advertising content on a web page.
