Clickjacking is a malicious technique used on the web to trick users into performing actions they did not intend, often leading to the revelation of confidential information or unauthorized actions.
This is achieved by layering a transparent or opaque iframe containing a malicious page over a legitimate web page. Users are lured to click on what appears to be a benign element on the visible page (e.g., a button), but their click is actually registered by the hidden malicious layer. This allows attackers to hijack clicks, making users unknowingly click on buttons or links that execute harmful actions, such as transferring money, changing passwords, or revealing sensitive data.
Clickjacking is also known as a “UI redress attack”. Websites can protect against clickjacking using techniques like X-Frame-Options HTTP headers (like DENY or SAMEORIGIN) or JavaScript-based frame-breaking code.
