Top 10 Hackers In The World (Most Notorious Black Hat hackers)

In general terms, a hacker can be any computer expert who’s highly skilled in their field and can find new exploits and vulnerabilities in the system or network.

Depending on the field of work, the term hacker takes on a controversial and unethical meaning.

The image that comes to your head when you think of a hacker, is usually a back-hat hacker. Black hat hackers are the ones who violate computer security for personal gain and benefit or for pure maliciousness.

Whereas, white hat hackers are those who help organizations or governments by reporting the flaws, and exploits they find in the network or system.

Below are some of the most well-known black hat hackers.
