Since the beginning of the information age have been a group of people who have given an impulse by the curiosity and the creation to several technologies, a society that has largely changed by the advance of computer science and the rise of Information and Communications Technologies (ICTs). These characters have sparked controversy at all levels, especially due to ignorance and sensationalism of the media, those who have been stigmatized in the public eye, within the limits of computer crime or terrorism. Under these conditions, the term hacker for many is synonymous with computer crime, vandalism, cyberterrorism and for the few, the people great, innovative, creative, and disciplined and with a constant desire to learn more than anyone. This article seeks to demystify the term hacker and is the result of a serious, thoughtful and dedicated Hacker Phenomenon, seeking justice for their actions and highlight the enormous contributions made to computer science and the development of ICT, based on analysis of the hacker phenomenon under different research topics (technical, social, cultural, legal, political and economic).
