Top 10 Greatest Hackers of All Time

When you think of the greatest hackers in history, you might imagine figures who changed the digital world, pushed boundaries, or made headlines for their ingenuity. This list brings together some of the most well-known names in the hacking world - people who have shaped technology, exposed vulnerabilities, or sparked intense debates about privacy, security, and ethics.
The Top Ten
XTAM4

He did not invent anything, but he shaped hacking. He has done operations with CWI that range from bad to good, fighting for equal rights and being the most contributing guy in the #OP Killuminati. He has a great story about where he started. I also know him in real life.

Xtam4 is a black hat hacker who got his fame around 2013-14. Through his group, he controlled many major hacking groups by controlling their leaders. Most of the deep web market websites and forums are also controlled by him. He might not be a very heroic figure, but since this list is in terms of hacking skills, power, and contribution, I think he should be number 1. His army of hackers outnumbers many hacking groups and are not random hackers who are new to the web. Most votes here are from the IRC. That's what I figured. This is the answer for those asking who Xtam4 is. You can also check Wikipedia for GForce Pakistan.

Mauritania Attacker The Mauritania Attacker is associated with hacktivist campaigns targeting government and financial institutions. The attacker is known for exploiting vulnerabilities to deface websites and leak data.

Thanks, I learned coding and hacking, and he has a lot of haters who still ignore who he is because he never teaches or answers skids. That's why they hate him haha. Also, they dislike him because he did not accept many people into the AnonGhost Team.

This is the difference between AnonGhost and Anonymous.

In my opinion, Mauritania Attacker is the most talented hacker in the world. Love you, my bhai.

@Haxor_Pk_1337

Seriously, he is the best hacker in the world. Thanks to him, the cyber world has progressed, and he has a lot of knowledge and talent.

You can't compare any hacker to him. You are the best in the world, no doubt.

Robert Morris Robert Morris created the first worm to spread widely across the internet in 1988, known as the Morris Worm. This attack led to the first felony conviction under the U.S. Computer Fraud and Abuse Act.
George Hotz (Geohot) George Hotz, known as Geohot, gained fame for unlocking the first iPhone and hacking the PlayStation 3. He has since worked in AI research and founded tech companies like Comma.ai.

Come on! He should be the best hacker in the world. He invented jailbreaking Apple devices and could hack Sony, which is really hard!

Yes, I agree, but Mauritania Attacker is still the best. Go check the archive and see the difference.

Exploited the entire iPhone. +1 badass.

Kevin Poulsen (Dark Dante) Kevin Poulsen, also known as "Dark Dante," is a former hacker who gained notoriety for taking over radio station phone lines to win contests. He later became a journalist, focusing on cybersecurity and digital privacy.

Phreaked his way to a new Porsche with a radio contest on an LA station. Arrested and jailed, he went on to become a journalist and editor at Wired.

Shawn Fanning Shawn Fanning is the creator of Napster, a peer-to-peer file-sharing service launched in 1999. His work sparked a revolution in digital music distribution and legal battles over copyright.

Should be number 1. There should be no hacker like MA on this list.

He must be third after Kevin Mitnick and Mauritania Attacker.

He's totally a great talent.

VallaH

Not the best, but Xtam4 is great. No disrespect to him! VallaH for #2!

VallaH is a great hacker. Should be above Dark Dante and Geohots.

Gordon Lyon (Fyodor) Gordon Lyon, known as Fyodor, is the creator of the Nmap Security Scanner, a popular tool for network discovery and security auditing. He is a prominent figure in the cybersecurity community and author of related books and articles.

The creator of Nmap!

Karl Koch (Hagbard) Karl Koch, known as Hagbard, was a German hacker involved in Cold War-era cyber espionage. He was part of the Chaos Computer Club and associated with hacking for the KGB before his mysterious death in 1989.

The great Karl Koch!

Adrian Lamo Adrian Lamo was known as the "Homeless Hacker" for breaching high-profile systems like The New York Times. He later became infamous for reporting Chelsea Manning's leaks of classified U.S. government documents.

My favorite till now.

Jonathan James Jonathan James, known as "c0mrade," was the first juvenile to be incarcerated for hacking in the United States. He gained access to NASA systems and other high-profile networks before his death in 2008.

16-year-old black hat hacker. In an anonymous PBS interview, he professes...

Gary McKinnon Gary McKinnon is a British hacker who breached U.S. military and NASA systems, claiming to search for evidence of UFOs. His actions led to a high-profile extradition battle with the United States.
Kevin Mitnick Kevin Mitnick is a former hacker once listed as one of the FBI's most-wanted cybercriminals for unauthorized access to corporate networks. He later became a security consultant and author, advocating for improved cybersecurity practices.

I vote for Kevin Mitnick, but I don't think MA made any techniques. It was Kevin who made techniques for hackers.

Great hacker. I vote for him, but I can't forget Mauritania Attacker, who changed the cyber world with some new techniques!

Edward Snowden Edward Snowden is a former NSA contractor who leaked classified information about global surveillance programs in 2013. His disclosures sparked global debates about privacy and government overreach.

Hackers shall never express weakness. Whistleblowers hold the same constitutional immunity as the head of state.

Whistleblowers should embrace their end for exposing what the government keeps hidden that isn't public domain.

Hero of hackers.
