Types of hackers

What are the three main types of hackers?

Hackers fall into three general categories: black hat hackers, white hat hackers, and gray hat hackers. Although hackers are often associated with exploiting vulnerabilities to gain unauthorized access to computers, systems, or networks, not all hacking is malicious or illegal.

In its purest sense, hacking is simply the application of computer skills to solve a particular problem. There are many different types of hackers, and a lot of hacking activities are beneficial, because they uncover programming weaknesses that help developers improve software products.

Black hat hackers

Black hat hackers are cyber criminals that illegally crack systems with malicious intent. Seeking to gain unauthorized access to computer systems is the definition of black hat hacking. Once a black hat hacker finds a security vulnerability, they try to exploit it, often by implanting a viruses or other types of malware such as a Trojan.

White hat hackers

White hat hackers are ethical security hackers who identify and fix vulnerabilities. Hacking into systems with the permission of the organizations they hack into, white hat hackers try to uncover system weaknesses in order to fix them and help strengthen a system’s overall security.

Gray hat hackers

Gray hat hackers may not have the criminal or malicious intent of a black hat hacker, but they also don’t have the prior knowledge or consent of those whose systems they hack into. Nevertheless, when gray hat hackers uncover weaknesses such as zero days vulnerabilities, they report them rather than fully exploiting them. But gray hat hackers may demand payment in exchange for providing full details of what they uncovered.

Other types of hackers

Although nearly all hackers fall into one of the three categories (black hat, white hat, or gray hat), there are other types and sub-types of hackers.

• Green hat hackers: Green hat hackers are “green” in the sense that they’re inexperienced and may lack the technical skills of more experienced hackers. Green hats may rely on phishing and other social engineering techniques to bypass security systems.
• Blue hat hackers: Blue hat hackers are white hat hackers who are actually employed by an organization to help improve their security systems by conducting penetration tests.
• Red hat hackers: Also known as vigilante hackers, red hat hackers are motivated by a desire to fight back against black hat hackers, but they do this by infiltrating black hat communities on the dark web and launching hacking attacks against their networks and devices.
