It was not very different. but in its beginnings I frame an era that changed the course of the informatics and forced to grow and improve the security systems, using the knowledge of hackers to improve systems that did not have any defenses. This is called white hat hackers who were interested in improving systems and not harming them. In addition to that the hacker ethic written in the hacker's bible explains a lot about the way of thinking of a hacker. I think that with the knowledge they have, they can do many good things. but they only think at the moment of stealing and doing harm.
