cracking n. very common the act of breaking into a computer system;
   what a cracker does. contrary to widespread myth, this does not
   usually involve some mysterious leap of hackerly brilliance, but rather
   persistence and the dogged repetition of a handful of fairly well-known
   tricks that exploit common weaknesses in the security of target systems.
   accordingly, most crackers are only mediocre hackers.
