Crackers are computer criminals; they often use their skills to steal information (such as for blackmailing) or money directly from bank accounts, or to disrupt systems to cause havoc or frame people for crimes they did not commit. At their extremes, they can be cyber-terrorists.
They are commonly confused with Hackers. In actual fact, a hacker is a neutral term, being one that only means being skilled at making computers do things outside their original specifications while crackers use these skills illegally or at least immorally. As such, all crackers are hackers, but not all hackers are crackers.
