QARK made no attempt to confirm, as the protection would have to be custom code, which is difficult for QARK to examine and understand properly. This vulnerability allows a malicious application to lay on top of this app, while letting the key strokes pass through to the application below. This can cause users to take unwanted actions, within the victim application, similar to Clickjacking on websites. Please select the appropriate options in the exploitation menus to verify manually using QARK's exploit APK. Note: The QARK proof-of-concept is transparent, but in real-world attacks, it would likely not be. This is done solely to aid in testing.
