Clickjacking

Is a malicious technique of tricking a Web user into clicking on something different from what the user perceives they are clicking on, thus potentially revealing confidential information or taking control of their computer while clicking on seemingly innocuous web pages. On a clickjacked page, the attackers load another page over it in a transparent layer, in most cases using HTML FRAME based techniques. The users think that they are clicking the buttons they are actually seeing, while they are in fact performing actions on the hidden page. This way the attackers can trick users into performing actions which the users never intended. There is no way of tracing such actions to the attackers later, as the users would have been genuinely authenticated on the hidden page.
