#Type of Hacker

#1 Gray Hat

The term "grey hat" or "gray hat" in Internet slang refers to a computer hacker or computer security expert whose ethical standards fall somewhere between purely altruistic and purely malicious. The term began to be used in the late 1990s, derived from the concepts of "White hat" and "black hat" hackers.

Gray Hat describes a cracker (or, if you prefer, hacker) who exploits a security weakness in a computer system or product in order to bring the weakness to the attention of the owners. Unlike a black hat, a gray hat acts without malicious intent. The goal of a gray hat is to improve system and network security. However, by publicizing a vulnerability, the gray hat may give other crackers the opportunity to exploit it. This differs from the white hat who alerts system owners and vendors of a vulnerability without actually exploiting it in public.

#2 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. 

A white hat hacker is a computer security specialist who breaks into protected systems and networks to test and asses their security. White hat hackers use their skills to improve security by exposing vulnerability before malicious hackers can detect and exploit them. although the methods used are similar, if not identical, to those employed by malicious hackers , White hat hackers have permission to employee them against the organization that has hired them.

#3 Black hat Hacker

A person who breaks into a computer system with the purpose of infliction damage or stealing data. In other words, a "boy Guy". Contrast with while hat hacker . Black hat is used to describe a hacker who breaks into a computer system or network with malicious intent. Unlike a white hat hacker, the black hat hacker takes advantage of the break-in ,perhaps destroying files or stealing data for some future purpose. The black hat hacker may also make the exploit known to other hackers and/or the public without notifying the victim. This gives others opportunity to exploit the vulnerability before the organization is able to secure it.Black hat hackers can inflict major damage on both individual computer users and large organizations by stealing personal financial information, compromising the security of major systems, or shutting down or altering the functions of websites and networks.
