1. A method of uncovering logic flaws of a graphical user interface (GUI) comprising:

  • mapping a visual invariant that is seen by a user, to a program invariant comprising Boolean flags associated with an execution context, the mapping based on a browser'"'"'s logic for mouse handling and page loading;

    discovering inputs to GUI logic that include user actions and execution context to cause the program invariant to be violated; and

    identifying the logic flaws of the GUI based on the inputs that cause the program invariant to be violated;

    wherein the visual invariant relates consistency between a user'"'"'s visual perception and a browser state; and

    wherein the discovering is used as a guidance for constructing real visual spoofing attacks.
