Abstract
Devices, systems, and methods to detect malware, particularly an overlay malware that generates a fake, always-on-top, masking layer or an overlay component that attempts to steal passwords or other user credentials. A defensive module protects a victim application, particularly of an electronic device having a touch-screen. The defensive module generates a transparent or invisible always-on-top layer of its own; and periodically injects automatically-generated non-human tap events or touch-gesture events, and checks whether the injected events are indeed received, in order to determine whether an overlay malware is active.
