A method for defeating wireless signal interference hacks is described. The method may include monitoring operations associated with user input of a user into an application on a mobile computing device. The user input may include physical interaction by the user's fingers with the mobile computing device causing signal interference by the fingers with a wireless signal transmitted by the mobile computing device such that a position of the fingers is detectable by a third party receiving the wireless signal. The method may include detecting an information entry event based on the monitored operations, modifying a wireless signal strength of the wireless signal transmitted by the mobile computing device from a standard signal strength level such that the position of the fingers of the user on the mobile computing device is not detectable by the third party receiving the wireless signal in response to detecting the information entry event.
