JavaScript Clickjacking

Description: Clickjacking is a malicious technique that deceives users into clicking on elements of a web page that are not what they appear to be. This vulnerability exploits user trust and graphical interfaces, overlaying invisible or misleading elements over legitimate content. For example, an attacker can create a frame (iframe) that hides an ‘Accept’ button on a legitimate page, while the user believes they are clicking a different button. This technique can lead to unwanted actions, such as triggering functions on social networks, authorizing payments, or disclosing personal information. The deceptive nature of clickjacking makes it a significant threat in web security, as it can be difficult to detect for both users and developers. To mitigate this vulnerability, it is recommended to implement security measures such as using HTTP headers that prevent the page from being included in iframes, as well as validating user actions through additional authentication techniques. In summary, clickjacking represents a constant challenge in protecting online privacy and security, requiring ongoing attention from both developers and users alike.

History: The term ‘clickjacking’ was coined in 2008 by security researcher Jeremiah Grossman and security engineer Robert Hansen. In that year, several articles were published describing how attackers could manipulate a web page’s user interface to deceive users. Since then, clickjacking has evolved and become more sophisticated, with attacks using advanced techniques to bypass security measures.

Uses: Clickjacking is primarily used to steal personal information, perform unauthorized actions on social media accounts or online services, and to spread malware. Attackers can create fake websites that mimic legitimate ones, deceiving users into making clicks that compromise their security.

Examples: An example of clickjacking occurred in 2010 when it was discovered that a malicious website was using this technique to trick Facebook users into ‘liking’ pages without their consent. Another notable case was the attack on the video platform YouTube, where attackers could make users click on misleading ads that led to unwanted websites.
