Top 10 Greatest Hackers

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.

To an intelligent person, all of this is very clear. You fear what you hate. Mauritania hates Xtam4, and his monkey followers follow him whatever he does. You can see they can't even speak proper English. They are poorly educated hackers.

I am one of the guys on Xtam4's team. I happened to stumble upon this list. Not a single member of our group cared about this list. Their goals happen to be much bigger than this list. But Anonghost just wants to win this list. You can see the difference between those two hacking groups. It's a very big difference. One has great heights to accomplish, and the other comes to the same list every day to spam and flame comments with their half-broken English. Farewell.

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

Exploited the entire iPhone. +1 badass.

MA above this guy? What a joke. I guess ISIS did really make some impact on the cyberworld.

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

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

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.

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!

Probably the best hacker! Has contributed a lot to all hackers, shared 0-days and free tools! Also, a great developer!

Just a defacer, but not like Mauritania Attacker, who is a Doctor!

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.
