Clickjacking, also known as UI redressing, is in the click fraud category and is a method used by criminal hackers to make users unknowingly perform certain actions by clicking on buttons or links. The objectives of clickjacking include the control of other people’s PCs as well as the redirection of users to paid content or fraudulent websites. Today, many large portals, such as Facebook, have to come up with measures against clickjacking.
Here, the users in the foreground click on game elements that change the configurations of their computers or browsers, which in the process makes them more vulnerable to hackers.
These are used by Internet fraudsters to lure the user to click on a download link. The link then loads malicious programs in the background.
With frames, every button on a website can basically be manipulated to make the user unknowingly trigger the actions desired by the hacker.
Social networks are also affected by the clickjacking problem. In this case, the clickjacking technique is used to make users who click on a link automatically become Facebook fans of a Facebook page. However, the network reacted very fast to this trend and has taken up legal measures against clickjacking methods that fraudulently collect Facebook fans since 2012.
