And why are they doing it? ............................................................................................................................. building Hacking (English verb to hack, singular noun a hack) refers to the re-configuring or re-programming of a system to function in ways not facilitated by the owner, administrator, or designer. The term(s) have several related meanings in the technology and computer science fields.
