A Hacker is a person who is skilled in computer programs and utilizes their technical knowledge to finds and exploits the weakness in computer systems to gain unauthorized access. In this post, we will explain different types of hacker in the world of hackers.
Different Types of Hacker
There are different types of hacker in the cyber world such as white hat, black hat, and grey hat hacker. A hacker may steal information, damage or bring down computer systems and networks. However, a hacker can be anyone and they can be an individual or group.
Many organizations who hire hackers as a part of their employee. These types of hackers use their technical skills to find out vulnerable and weakness in the organization’s security system. This is done to find and fix the weaknesses and prevent cyber threat from breaking in the security system.
- Black Hat Hackers
- 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.
Black Hat hackers are expert in the cyber hacking to break into a computer system without the system owner’s authorization. After getting access of a system, they can send phishing email to others, install malware into your system and can sell financial and sensitive information on the Dark Web.
The term “black hat hacker” is derived from old Western movies, in which the good guys wore white hats and the bad guys wore black hats.
2. White Hat Hacker
A white hat hacker is types of hacker who is security specialist and uses skills to breaks into a system for penetration testing and strengthens the security of your system.
White Hat hackers are also known as Ethical Hackers. They never intent to harm a system, rather they try to find out security weaknesses and vulnerabilities in a computer or a network system.
In addition, this type of hackers is not illegal and it is one of the demanding jobs available in the IT industry. White hat hackers are paid employees or contractors working for companies as security specialists that attempt to find security holes via hacking.
Most White Hat hackers hold an academic degree in IT security and must be certified to pursue a career in hacking. The most of them have a popular certification is the CEH (Certified Ethical Hacker) from the EC-Council.
Typically, white hat hackers do the following jobs:
- Find out the security vulnerabilities of a system
- Install the security system such as antivirus, SSL certificate, Web application Firewall
- Develop a cyber-security tool that can identify the cyber threats
- Uses penetration testing tools for ensure security
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.
4. Red Hat Hackers
Red Hat Hackers is types of hackers who take the necessary steps to stop the black hat hacker’s activities in cybercrime. This types of hacker is almost similar to white hat hackers. The key difference between red hat hacker and white hat hackers is to their hacking intension.
Basically, White Hat hackers are Ethical Hackers who breaks into a system for penetration testing and strengthens the security of a system. And red hat hackers take a wrong initiative to protect a system from black hat hackers.
Red hat hacker’s uses use different types of attacking tools and technique to attack the bad hat hackers and infect malware within their systems.
The main aim of red hat hackers is to save the computer and cyber world from black hat hackers but using an illegal steps.
5. Green Hat Hackers
It is another types of hacker in the world of cyber hacking. Green hat hackers are learning and working on hacking techniques in order to improve their technical skills to become a better hacker.
Typically, they are “newbies” in the hacking domain and learning day by day. Actually, green hat hackers don’t have deep knowledge about hacking tactics and they are not aware about cyber security.
Simply put, they are dangerous because they have no technical skill on how to fix a security problem of a system. They always gather knowledge from experienced hackers and practice on a life system.
6. Script Kiddies Hackers
Script kiddie hackers are less experience young malicious hackers who have half knowledge in the field of cyber hacking. These types of hacker are try to hack a system with malicious script which has taken form expert hackers. That’s why this types of hacker is called Script kiddie hackers.
They aren’t not trying to improve their technical skills of hacking and they don’t know how to write a hacking script. This type of hacker aren’t good programmer and they uses a script which has developed by others cyber hackers. Script kiddie hackers are enjoying as it fun or a game for entertainment.
They are try to get unauthorized access or hack of a computer system, networks or websites of an organization.
7. Blue Hat Hackers
Blue hat hackers or BlueHat is a types of hacker in the cyber world who works outside of the organization to scrutinize the possible security holes of an application. They are invited by companies in order to find out the security vulnerabilities of a new application before implementation.
Blue hat hackers use various hacking technics and inject malware on their enemies’ servers or networks to take individual revenge. They can destroy the enemies’ data, websites and applications.
They can also gain unauthorized access of an email system and send phishing or inappropriate emails to their targets’ email address. This type of hackers are dangerous because their intention is to hack data and damage the reputation of their enemies’.
