You must have heard about Cybercrime, if I have not heard, I will tell you. Cybercrime is a crime in which hackers use computers to steal important data and personal files from other people’s computers and blackmail them and demand a lot of money from them. Every year due to cybercrime, many organizations whose data have been stolen, people have to pay millions of rupees to save their data.

In the computer world, this crime is increasing and in such a situation, everyone needs to save their important files of their company and business from these hackers. But here the question arises that after all how to protect the important files kept in computers from being stolen. If you want to know the answer to this question, then read this article, what is Hacking ? And is it legal or illegal ?

What is Hacking ?

Hacking means finding the weakness in the computer system and then taking advantage of the same weakness to blackmail the owner of that computer. Hacking is done by a person through a computer, which we call hacker and he has a lot of knowledge of computer and computer knowledge, so he is expert in stealing data from other computers. On hearing the name of Hacking, it is known that this is a wrong thing because it is illegal and by doing so a person can be punished. But hacking is not wrong every time because not all hackers are the same, some are good hackers and some are bad hackers. Who are the good and bad hackers and what do they do? Let’s find out about it further.

History of Hacking and what is done in Hacking

Hacking has been a very big part of computing for the last several decades. This is a very broad discipline, which covers a wide range of topics. If we find out when this hacking happened first, then we will know that it was first used in the year 1960 in MIT , and at the same time the word ” Hacker ” was also born and which later became very famous.

If I talk about the process of Hacking technically, then the main task that has to be done in it is to find the possible entry points in any computer network or computer system and then finally enter it. Hacking usually involves gaining unauthorized access to a computer system or computer network . Its purpose is to either damage the system or steal the sensitive information in the system.

Hacking is often legal as long as a hacker uses it to discover the weaknesses of a computer system or computer network for testing purpose. This type of hacking is called Ethical Hacking.

A computer expert who does this hacking himself is called an ” Ethical Hacker “. Ethical hackers are those who always use their knowledge to gain knowledge, how systems operate, how they are designed, and sometimes to test the security strength of the system.

Types of Hacking

We can divide Hacking into different categories, for this we will see what has been hacked. I will give you some examples to explain you

  • Website Hacking – This type of Hacking means to gain unauthorized control over a web server and its associated software such as databases and other interfaces.
  • Network Hacking – This type of Hacking means to get all the information over a network and for which there are many tools like Telnet, NS lookup, Ping, Tracert, Netstat, etc. The main purpose of doing this is only to harm the network system and its operation.
  • Email Hacking – This type of Hacking means that the hacker gets unauthorized access to his email account without the owner’s permission. Later, he is going to use it for his illigal works.
  • Ethical Hacking – This type of Hacking means identifying the weaknesses of a system or network and helping the owner to fix it. This is a safe hacking process in which all work is done under the supervision of the owner.
  • Password Hacking – This type of Hacking means in which secret passwords are retrieved from data which is stored or transmit in the computer system by a computer system.
  • Computer Hacking – This type of Hacking means that in which the hacker knows the computer ID and password of a computer system, air using hacking methods so that they gain unauthorized access to a computer system. This puts owners at risk of getting their data stolen.

What are the types of hackers?

Basically hackers are of three types, two of them are bad hacker who harm people by doing bad work and one hacker is good which saves us from both these bad hackers. The good hacker is called the white hat hacker, the bad hacker is called the black hat hacker and the one who comes between these two means the one who does both good and bad work is called gray hat hacker.

1# Black Hat Hacker

Black hat hacker are those who sneak into your computer without your permission and steal your personal data like corporate data, fund transactions details, ATM card details etc. Many things that we keep in the computer, which these hackers They steal and take advantage of our weakness and ask for ransom from us. Black hat hackers are very bad and they harm the other for their benefit.

2# White Hat hacker

White hat hackers are those people who do the complete opposite of the black hat hacker, that is, these hackers take permission and check the security of the computer, they do it only to know or to help a company. How strong is the security of their system and whether that security can be broken easily or not. We are also called White hat hackers as Ethical hacker.

3# Grey Hat Hacker

Gray hat hacker are those who do not have any personal intention to mess with the computer data of others or to spoil their system and they do not need money in return. But still, without permission, we try to hack others’ computers using their skills. They do this just to learn how to do hacking, so their motive is not bad, so they are not black hat hacker and they tried to hack the computer without permission, so they are not even white hacker, so such hacker We say gray hat hacker.
Apart from this, there are some different types of Hackers, which have provided the information below.

4# Miscellaneous Hacker

Except for the second class of hackers, they are also distributed for their hacking methods. So let’s know more about it.

Red Hat Hackers

They are called red hat hackers which is a mixture of both black hat and white hat hackers. She mainly targets government agencies, top-secret information hubs, and all those things which are related to sensitive information to hack them.

Blue Hat Hackers

Blue Hat Hackers are called those who are often freelancer and do not work for any companies but they have complete knowledge about network security, apps, software. Such hackers are used by companies to know the loopholes of their products, for this they provide beta verison of products to them and after all they help companies a lot in this work. Companies also provide them very good money. Many companies organize many such competitions to encourage such blue hat hackers.

Elite Hackers

This is a social status among the hackers community, which is available only to selected hackers who have exceptional skills. Like this, they are the most expert players in their work. All newly discovered exploits are the first of these hackers.

Script Kiddie

A script kiddie is called one who is completely non-expert in his field and uses pre-packaged automated tools that are written by others to penetrate someone’s computer systems. They do not know anything about those tools and how they work, and that is why they go to Kiddie.


These are the hackers who are “n00b”, or “newbie” or “Green Hat Hacker”. These people are often new in the field of hacking, who do not know anything about hacking and its technologies.


A hacktivist is called a hacker who uses technology to hack a social, ideological, religious, or political message. In this, most people use website defacement and denial-of-service attacks.

What is Ethical Hacking ? Is this legal or Illegal ?

You have come to know the three types of Hacking and it would have also come to know that it is legal to do Ethical Hacking because this hacker hacks the computer by asking and improves the security of the system. Ethical hacker follows some rules to hack the system which is very important such as permission has to be taken before the owner of the computer, protects the privacy of the computer so that no one else can hack, discover the weakness of the computer The tax gives all the details to its owner by making a report.

By doing all these things, Ethical hacker protects a person or a company from the eyes of a bad hacker and also prevents them from being harmed. Big companies hire Ethical hacker in their company to secure their necessary files and corporate data and also give them good salary.
