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.
