A hacker is a self motivated person who seeks and exploits weaknesses in a computer system or computer network in order to steal or change or destroy information. Hackers learn through experimentation and persistence, as opposed to through “traditional” means. Hackers listed below are the worlds top 5 most famous hackers.
Gary McKinnon (born 10 February 1966) is a Scottish system administrator and hacker who was accused in 2002 of perpetrating the “biggest military computer hack of all time,”. He Hacked 97 United States military and NASA computers over a 13-month period between February 2001 and March 2002, at his girlfriend’s aunt’s house in London,using the name ‘Solo’. Although McKinnon claimed that he was only searching for information related to free energy suppression and UFO activity cover-ups. But according to U.S. authorities, he deleted a number of critical files, rendering over 300 computers inoperable and resulting in over $700,000 in damages. McKinnon also posted a notice on the military’s website: “Your security is crap”.
US foreign policy is akin to Government-sponsored terrorism these days … It was not a mistake that there was a huge security stand down on September 11 last year … I am SOLO. I will continue to disrupt at the highest levels.Gary McKinnon

4. Andrian Lamo
Adrian Lamo (born February 20, 1981) is an American threat analyst and “grey hat” hacker. He first gained media attention for breaking into several high-profile computer networks, including those of The New York Times, Yahoo!, and Microsoft, culminating in his 2003 arrest.
He was named ‘the homeless hacker’ for his penchant for using coffee shops, libraries and internet cafés as his bases for hacking. According to The Week, Lamo broke into the networks of a number of major companies — Excite@Home, MCI WorldCom, Yahoo, Microsoft and Google — but he often contacted the companies and told them about the security holes. He finally got into trouble when he hacked into The New York Times — from a computer at a Kinko’s — in 2003. He found a trove of information there, including personal details on thousands of people who had written for the paper, including celebrities and ex-presidents. To avoid jail time, he negotiated a plea bargain that included six months of house arrest. Lamo currently works as a journalist.
