Abstract
Systems and methods for obfuscating keyboard keys against interception are provided. In an example, a protected application is dynamically virtualized in user space, wherein the virtualization comprises an isolated keyboard path. Keystrokes are injected to the isolated keyboard path, wherein the injected keystrokes are associated with a respective timestamp, and user input keystrokes are obfuscated with the injected keystrokes and the obfuscated keystrokes are passed to a low level hook. The obfuscated keystrokes passed to the low level hook are separated according to tags associated with the obfuscated keystrokes to obtain the user input keystrokes. The user input keystrokes are transmitted to a target window of the protected application.
