• Clickjacking: An adversary tricks a victim into unknowingly initiating some action in one system while interacting with the UI from a seemingly completely different, usually an adversary controlled or intended, system.
• Flash File Overlay: An attacker creates a transparent overlay using flash in order to intercept user actions for the purpose of performing a clickjacking attack. In this technique, the Flash file provides a transparent overlay over HTML content. Because the Flash application is on top of the content, user actions, such as clicks, are caught by the Flash application rather than the underlying HTML. The action is then interpreted by the overlay to perform the actions the attacker wishes.
• iFrame Overlay: In an iFrame overlay attack the victim is tricked into unknowingly initiating some action in one system while interacting with the UI from seemingly completely different system.
• Task Impersonation: An adversary, through a previously installed malicious application, impersonates an expected or routine task in an attempt to steal sensitive information or leverage a user's privileges.
• Tapjacking: An adversary, through a previously installed malicious application, displays an interface that misleads the user and convinces them to tap on an attacker desired location on the screen. This is often accomplished by overlaying one screen on top of another while giving the appearance of a single interface. There are two main techniques used to accomplish this. The first is to leverage transparent properties that allow taps on the screen to pass through the visible application to an application running in the background. The second is to strategically place a small object (e.g., a button or text field) on top of the visible screen and make it appear to be a part of the underlying application. In both cases, the user is convinced to tap on the screen but does not realize the application that they are interacting with.
• Cross Frame Scripting (XFS): This attack pattern combines malicious Javascript and a legitimate webpage loaded into a concealed iframe. The malicious Javascript is then able to interact with a legitimate webpage in a manner that is unknown to the user. This attack usually leverages some element of social engineering in that an attacker must convinces a user to visit a web page that the attacker controls.
• Credential Prompt Impersonation: An adversary, through a previously installed malicious application, impersonates a credential prompt in an attempt to steal a user's credentials.
