Clickjacking

Sažetak
|
In a clickjacking attack the victim is tricked into unknowingly initiating some action in one system while interacting with the UI from a seemingly completely different system. While being logged in to some target system, the victim visits the adversary's malicious site which displays a UI that the victim wishes to interact with. In reality, the clickjacked page has a transparent layer above the visible UI with action controls that the adversary wishes the victim to execute. The victim clicks on buttons or other UI elements they see on the page which actually triggers the action controls in the transparent overlaying layer. Depending on what that action control is, the adversary may have just tricked the victim into executing some potentially privileged (and most certainly undesired) functionality in the target system to which the victim is authenticated. The basic problem here is that there is a dichotomy between what the victim thinks they are clicking on versus what they are actually clicking on.

['If using the Firefox browser, use the NoScript plug-in that will help forbid iFrames.', 'Turn off JavaScript, Flash and disable CSS.', 'When maintaining an authenticated session with a privileged target system, do not use the same browser to navigate to unfamiliar sites to perform other activities. Finish working with the target system and logout first before proceeding to other tasks.']
