Types of Hacker

Types of Hacker

Let’s see the categories of Hackers on the basis on their knowledge.

Coders

 The Real Hackers are the Coders, the ones who revise the methods and create tools that are available in the
market. Coders can find security holes and weaknesses in software to create their own exploits. These Hackers
can use those exploits to develop fully patched and secure systems.

 Coders are the programmers who have the ability to find the unique vulnerability in existing software and to
create working exploit codes. These are the individuals with a deep understanding of the OSI Layer Model and
TCP/IP Stacks.

Admins

 Admins are the computer guys who use the tools and exploits prepared by the coders. They do not develop their
own techniques, however they uses the tricks which are already prepared by the coders. They are generally
System Administration, or Computer Network Controller. Most of the Hackers and security person in this digital
world come under this category.

 Admins have experience with several operating systems, and know how to exploit several existing vulnerabilities.
A majority of Security Consultants fall in this group and work as a part of Security Team.

Script Kiddies

 Next and the most dangerous class of Hackers is Script kiddies, They are the new generation of users of computer
who take advantage of the Hacker tools and documentation available for free on the Internet but don’t have any
knowledge of what’s going on behind the scenes. They know just enough to cause you headaches but typically are
very sloppy in their actions, leaving all sorts of digital fingerprints behind. Even though these guys are the teenage
Hackers that you hear about in the news media, they need minimum skills to carry out their attacks.
 Script Kiddies are the bunnies who use script and programs developed by others to attack computer systems and
Networks. They get the least respect but are most annoying and dangerous and can cause big problems without
actually knowing what they are doing.

Types of Hackers on the basis of activities performed by them.

White Hat Hacker

 A White Hat Hacker is computer guy who perform Ethical Hacking. These are usually security professionals with
knowledge of hacking and the Hacker toolset and who use this knowledge to locate security weaknesses and
implement counter measures in the resources.
 They are also known as an Ethical Hacker or a Penetration Tester. They focus on Securing and Protecting IT
Systems

Black Hat Hacker

 A Black Hat Hacker is computer guy who performs Unethical Hacking. These are the Criminal Hackers or Crackers
who use their skills and knowledge for illegal or malicious purposes. They break into or otherwise violate the
system integrity of remote machines, with malicious intent.
 These are also known as an Unethical Hacker or a Security Cracker. They focus on Security Cracking and Data
stealing.

Grey Hat Hacker

 A Grey Hat Hacker is a Computer guy who sometimes acts legally, sometimes in good will, and sometimes not.
They usually do not hack for personal gain or have malicious intentions, but may or may not occasionally commit
crimes during the course of their technological exploits.
 They are hybrid between White Hat and Black Hat Hackers.

Ethical Hacking

Ethical Hacking is testing the resources for a good cause and for the betterment of technology. Technically Ethical
Hacking means penetration testing which is focused on Securing and Protecting IT Systems.

Hactivism

Another type of Hackers are Hacktivists, who try to broadcast political or social messages through their work. A
Hacktivist wants to raise public awareness of an issue. Examples of hacktivism are the Web sites that were
defaced with the Jihad messages in the name of Terrorism.

Cyber Terrorist

There are Hackers who are called Cyber Terrorists, who attack government computers or public utility
infrastructures, such as power stations and air-traffic-control towers. They crash critical systems or steal classified
government information. While in a conflict with enemy countries some government start Cyber war via Internet.
