Hackers Types

Hackers are of three types:-


1. White hat hacker
2. Gray hat hacker
3. Black hat hacker

White Hat and Grey Hat Hacker & What is the Real Difference?

What is worse, the public is not able to understand terms like grey hat, white hat, Linux OS, or cracker.
However, the truth is that the subculture of the hacker world is more complex than we think. Especially if we consider that, these are very intelligent people.


So, what is ethical hacking white hat and how does it differentiate from grey hackers? The only way to find out is to submerge ourselves in the world of hackers and understand, at least, the most basic concepts.


What Is A White Hat Hacker?
The term "white hat" in Internet slang refers to an ethical computer hacker, or a computer security expert, who specializes in penetration testing and in other testing methodologies to ensure the security of an organization's information systems.[1] Ethical hacking is a term meant to imply a broader category than just penetration testing.[2][3] Contrasted with black hat, a malicious hacker, the name comes from Western films, where heroic and antagonistic cowboys might traditionally wear a white and a black hat respectively.[4]

White-hat hackers may also work in teams called "sneakers",[5] red teams, or tiger teams.[6]
Today, anyone can become a hacker. Within that denomination, there are three types of hackers. The first one is the black hacker, also known as a cracker, someone who uses his computer knowledge in criminal activities in order to obtain personal benefits. A typical example is a person who exploits the weaknesses of the systems of a financial institution for making some money.
On the other side is the white hat hacker. Although white hat hacking can be considered similar to a black hacker, there is an important difference. A white hacker does it with no criminal intention in mind. Companies around the world, who want to test their systems, contract white hackers. They will test how secure are their systems, and point any faults that they may found. If you want to become a hacker with a white hat, Linux, a PC and an internet connection is all you need.


Grey Hat Hackers
A grey hat hacker is someone who is in between these two concepts. He may use his skills for legal or illegal acts, but not for personal gains. Grey hackers use their skills in order to prove themselves that they can accomplish a determined feat, but never do it in order to make money out of it. The moment they cross that boundary, they become black hackers.
The term "grey hat", alternatively spelled as "greyhat" or "gray hat", refers to a computer hacker or computer security expert who may sometimes violate laws or typical ethical standards, but does not have the malicious intent typical of a black hat hacker.
The term began to be used in the late 1990s, derived from the concepts of "white hat" and "black hat" hackers.[1] When a white hat hacker discovers a vulnerability, they will exploit it only with permission and not divulge its existence until it has been fixed, whereas the black hat will illegally exploit it and/or tell others how to do so. The grey hat will neither illegally exploit it, nor tell others how to do so.[2]
A further difference among these types of hacker lies in their methods of discovering vulnerabilities. The white hat breaks into systems and networks at the request of their employer or with explicit permission for the purpose of determining how secure it is against hackers, whereas the black hat will break into any system or network in order to uncover sensitive information and for personal gain. The grey hat generally has the skills and intent of the white hat but will break into any system or network without permission.[3][4]
According to one definition of a grey-hat hacker, when they discover a vulnerability, instead of telling the vendor how the exploit works, he or she may offer to repair it for a small fee. When one successfully gains illegal access to a system or network, he or she may suggest to the system administrator that one of his or her friends be hired to fix the problem; however, this practice has been declining due to the increasing willingness of businesses to prosecute. Another definition of Grey hat maintains that Grey hat hackers only arguably violate the law in an effort to research and improve security: legality being set according to the particular ramifications of any hacks they participate in.[5]
In the search engine optimization (SEO) community, grey hat hackers are those who manipulate web sites' search engine rankings using improper or unethical means but that are not considered search engine spam.[6]

Black Hat Hackers
Black hat hackers have become the iconic image of all hackers around the world. For the majority of computer users, the word hacker has become a synonym for social misfits and criminals. Of course, that is an injustice created by our own interpretation of the mass media, so it is important for us to learn what a hacker is and what a black hacker (or cracker) does. So, let’s learn about black hat techniques and how they make our lives a little more difficult.

black hat hacker (or black-hat hacker) is a hacker who "violates computer security for little reason beyond maliciousness or for personal gain".[1]
The term was coined by hacker culturetheorist Richard Stallman to contrast the exploitative hacker with the white hat hacker who hacks protectively by drawing attention to vulnerabilities in computer systems that require repair.[2] The black hat/white hat terminology originates in the Western genre of popular American culture, in which black and white hats denote villainous and heroic cowboys respectively.[3]
Black hat hackers are the stereotypically illegal hacking groups often portrayed in popular culture, and are "the epitome of all that the public fears in a computer criminal".[4]Black hat hackers break into secure networks to destroy, modify, or steal data, or to make the networks unusable for authorized network users.[5]
