Hacker is any skilled computer expert that uses their technical knowledge to overcome a problem. Hackers are most often programmers. They gather advanced knowledge of operating systems and programming languages and finds bugs or exploits to break into computer systems.

There are generally 10 types of Hackers  

White Hat Hackers

White hat hackers, also known as ethical hackers are the cybersecurity experts who help the Govt and organizations by performing penetration testing and identifying loopholes in their cybersecurity. They even do other methodologies and ensure protection from black hat hackers and other malicious cyber crimes.
Simply stated, these are the right people who are on your side. They will hack into your system with the good intention of finding vulnerabilities and help you remove virus and malware from your system.

Black Hat Hackers

Black Hat hackers, also known as crackers, are those who hack in order to gain unauthorized access to a system and harm its operations or steal sensitive information. Black Hat hacking is always illegal because of its bad intent which includes stealing corporate data, violating privacy, damaging the system, blocking network communication, etc. They are considered to be as criminals and can be easily identified because of their malicious actions.

Gray Hat Hackers 

Gray hat hackers fall somewhere in the category between white hat and black hat hackers. While they may not use their skills for personal gain, they can, however, have both good and bad intentions. For instance, a hacker who hacks into an organization and finds some vulnerability may leak it over the Internet or inform the organization about it. It all depends upon the hacker. Nevertheless, as soon as hackers use their hacking skills for personal gain they become black hat hackers. 

There is a fine line between these two. So, let me make it simple for you. Because a gray hat hacker doesn't use his skills for personal gain, he is not a black hat hacker. Also, because he is not legally authorized to hack the organization's cybersecurity, he can't be considered a white hat either.

Script Kiddies

Script Kiddies normally don’t care about hacking (if they did, they’d be Green Hats. See below.). They copy the code and use it for a virus or an SQLi or something else. Script Kiddies will never hack for themselves; they’ll just download overused software (LOIC or Metasploit, for example) and watch a YouTube video on how to use it. A common Script Kiddie attack is DoSing or DDoSing (Denial of Service and Distributed Denial of Service), in which they flood an IP with so much information it collapses under the strain. This attack is frequently used by the “hacker” group Anonymous, which doesn’t help anyone’s reputation.

Green Hat Hackers

These are the hacker “n00bz,” but unlike Script Kiddies, They care about hacking and strive to become full-blown hackers. They are inspired by the hackers and ask them few questions about. While hackers are answering their question they will listen to its novelty.

Blue Hat Hackers

These are another form of novice hackers much like script kiddies whose main agenda is to take revenge on anyone who makes them angry. They have no desire for learning and may use simple cyber attacks like flooding your IP with overloaded packets which will result in DoS attacksA script kiddie with a vengeful agenda can be considered a blue hat hacker

Red Hat Hackers 

They are also known as eagle-eyed hackers. Like white hat hackers, red hat hackers also aims to halt the black hat hackers. There is a major difference in the way they operate. They become ruthless while dealing with malware actions of the black hat hackers. Red hat hacker will keep on attacking the hacker aggressively that the hacker may know it as well have to replace the whole system.

State/Nation Sponsored Hackers

State or Nation sponsored hackers are those who are appointed by the government to provide them cybersecurity and to gain confidential information from other countries to stay at the top or to avoid any kind of danger to the country. They are highly paid government workers.


These are also called the online versions of the activists. Hacktivist is a hacker or a group of anonymous hackers who gain unauthorized access to government’s computer files and networks for further social or political ends.

Malicious Insider or Whistleblower

A malicious insider or a whistleblower could be an employee of a company or a government agency with a grudge or a strategic employee who becomes aware of any illegal activities happening within the organization and can blackmail the organization for his/her personal gain.
