- White Hat Hacker
- Grey Hat Hackers
- Red Hat Hackers
- Green Hat Hackers
- Script Kiddies Hackers
- Blue Hat Hackers
Now, we will define each types of hackers.
1. Black Hat Hackers
Black Hat hackers, also known as crackers are those who attempt to find security vulnerabilities and gain unauthorized access into an application or network for malicious reasons.
This types of hackers is illegal because of its bad intent which includes steal financial information, login credentials, disrupts the systems, violate the privacy, shutting down the network system.

It is noted that, some renowned companies like Facebook, Microsoft, and Google also use white-hat hackers.
3. Grey Hat Hackers
This types of hacker is someone who may violate ethical standards, but except the malicious intent they exploit a security weakness in a computer system without the owner’s permission.
The primary goal of grey hat hackers is to improve system and network security. This type of hackers is still considered illegal because the hacker has not taken any permission from the system owner’s to attempt to filter their systems.
It is combining of both black hat and white hat hackers. Their intent is to bring the weakness to the attention of the owners and getting appreciation or a little gift from the owners.
