Software cracking

Software hacking, aka software cracking, is the act of somehow amending a program do do a specified function that is usually unallowable by the program or purposefully locked out by the programmers. A good example would be a No CD hack, which edits the program so that the CD is no longer needed to execute the program.

There are may groups that a devoted to developing tools for software hacking called cracks or hacks. Those include the Phrozen Crew, UCF, Xpression, etc.
