5 Most Notorious Hackers of All Time in the World

Top 5 Most Famous Hackers in the World


In computer hacking, vulnerabilities in systems and networks are identified and exploited to gain unauthorized access to those systems. It is not all malicious hacking. Cybersecurity professionals, software engineers, and testers seeking out vulnerabilities can be considered white hat hackers. They act maliciously. Nevertheless, there is a large grey area in which political activists and hackers slip between both hats.

Kevin Mitnick

Computer security consultant, author, and convicted hacker Kevin David Mitnick hails from the United States. It is best known that he served five years in prison for various computer and communications-related crimes following his arrest in 1995.


The Anonymous movement and collective is a largely decentralized group of activists and hacktivists perhaps best known for their many cyberattacks against governments, government institutions, government agencies, corporations, and the Church of Scientology.

Adrian Lamo

Among his achievements was becoming an expert in threat analysis and hacking. Media attention first arose when Lamo broke into several high-profile computer networks, including those of The New York Times, Yahoo! and Microsoft, which culminated in his arrest in 2003.

Albert Gonzalez

A computer hacker and computer criminal named Albert Gonzalez is accused of stealing over 170 million credit card numbers from 2005 to 2007 and reselling them for more than $1 billion: the biggest such fraud in history.

Matthew Bevan and Richard Pryce

Several military networks were hacked by Matthew Bevan and Richard Pryce when they worked together in 1996, including Griffiss Air Force Base, the Defense Information System Agency and Korean Atomic Research Institute, as well as other military networks. A third world war could have been avoided if Bevan (Kuji) and Pryce (Datastream Cowboy) hadn’t pushed KARI research onto American military systems. According to the BBC, Bevan claims to be investigating a UFO conspiracy theory and his case resembles Gary McKinnon’s. Even military networks are vulnerable, whether or not they have malicious intent.
