: Hackers of the general nusiance variety will also send out Viruses and Trojans much the same as a vandal will sets fires or spray paint buildings.
Seeker is right. I have a modern 800 page book called "Maximum Security, a Hacker's Guide to Protecting Your Internet Site and Network." It was written by an expert who used to be a cracker and got caught.
According to this book, a hacker is someone who merely gets into systems for the sheer challenge of it, but does no damage. A "cracker" on the other hand, gets into systems for the sole purpose of causing mischief or conducting criminal activity.
The more hackers, the merrier, I say. As long as they continue to do their jobs, I.S. people will learn of their systems vulnerabilities and how to correct them.
