I might even be able to crash the whole damned system. Destroy all records of ownership. Think of it, Marty. No more rich people, no more poor people, everybody's the same, isn't that what we said we always wanted?
~ Cosmo, telling Marty about his plan to use the Black Box to bring down the world's economy.
Man is least himself when he talks with his own person. But if you give him a mask, he will tell you the truth. Two people, and a secret: the beginning off all conspiracies. More people, and, more secrets. But if we could find one moral man, one whistle blower. Someone willing to expose those secrets, that man could topple to most powerful and most repressive of regimes.

Don't you just love technology?

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.
