1. A term associated with any change not approved by the manufacturer or developer that makes the device do something it was not initially intended to do. For example, with software updates and modifications users can make their Xbox gaming console more of a media center. Because these modifications are not supported by the developer, hacks such as these will void your warranty and prevent you from getting support from the manufacturer.
2. A hack or hackz utility is a software program downloaded to help a user perform a hack on their computer or other computer or device.
