Abstract: Various examples relate to apparatuses, methods, and computer programs for executing an executable, and to a method for distributing software or firmware. An apparatus for executing an executable comprises interface circuitry, machine-readable instructions, and processing circuitry for executing the machine-readable instructions to identify, for the executable, a trigger to activate or deactivate a noise injection mode during execution of the executable, the noise injection mode being suitable for introducing noise during execution of the executable, and activate or deactivate the noise injection mode based on the identified trigger.
