Hacking has been a central theme in the digital age, with hackers playing a role in shaping the internet’s history and exposing vulnerabilities in online systems. Some hackers have used their skills for good, while others have caused significant damage. In this article, we’ll take a look at the top 10 most notorious hackers of all time and their exploits that made them famous.
1. Anonymous
Unlike individual hackers, Anonymous is a decentralized group of hacktivists known for launching high-profile attacks on governments, corporations, and organizations. The group is often associated with the Guy Fawkes mask, symbolizing rebellion against authority. Some of their most notable campaigns include Operation Payback (targeting organizations against piracy), attacks on the Church of Scientology, and supporting movements like Occupy Wall Street.

Kevin Mitnick is often considered the most famous hacker of all time. Known as the “most wanted computer criminal in U.S. history,” Mitnick hacked into major corporations such as Nokia, IBM, and Motorola. He specialized in social engineering, a method of manipulating people into giving away confidential information. Mitnick’s hacking spree ended in 1995 when he was arrested and sentenced to five years in prison. After his release, Mitnick turned his life around and became a cybersecurity expert, author, and consultant.
Why notorious? Mitnick’s ability to breach highly secure systems during his time made him one of the most feared hackers in history.
