INTRODUCTION TO COMPUTER HACKING

Updated: May 6


Nowadays the general public are crazy and desire to become a hacker, hacking isn't an art that may be mastered overnight. It requires knowledge, skills, creativity, dedication, and after all the time. In simple, hacking could be a technical skill of a personal. So it's good to have some extra skills or knowledge about hacking.

A hacker is someone who likes to play with electronics or computer systems. Hackers wish to explore and find out how computer systems work. They try to take advantage of vulnerabilities or weaknesses of software or hardware. Hacking is the process of getting unauthorized access to a system, network, or resources.



What Does Vulnerability Mean?

Today computer software is extremely complex and it contains thousands of lines of code. Since the software is written by humans, it's going to contain programming mistakes referred to as vulnerabilities. These loopholes are utilized by hackers to break into systems, they're also utilized by authors of malicious software to launch their programs automatically on your computer.

A person who is involved in hacking is called a hacker. Hacking isn't always illegal. Nowadays it's a profession. Companies hire hackers to break into their security to know the security holes in their security systems. These people are typically called "Penetration Testers" because they find, exploit, and report vulnerabilities back to an organization that has hired them. *Note, this is often an ethical practice only the service is requested by a company/individual. don't perform these styles of attacks/research on companies without permission


Some Characteristics of a Hacker

  • A person who thinks different

  • A person who is interested in hacking and cracking

  • A person who can learn to program quickly

  • A person who enjoys doing programming rather than its theory

  • A person who is loves the computer and the Internet

  • A person who is interested to know how a computer, website, and network devices works


Different Types of hackers

  1. Black Hat Hackers

  2. White Hat Hackers

  3. Gray Hat Hackers



1. Black Hat Hackers

These are all the bad guys, these people usually use their skills for his or her own personal gains or fun.

This category of hackers is also called "CRACKERS". These people are always tempted to gain a privilege of someone's system without authorization or permission. Usually, they work individually, but as a team, they will be deadly and their impact can cause trouble to a greater extent. They are the folks that hack banks, steal credit cards, and deface websites, etc.


2. White Hat Hackers

These are all the great guys, white Hackers are the lifesaving angels,

these categories of hackers are also called "ETHICAL HACKERS". These people don't use their skills for illegal purposes.

Usually, they are the Computer Security experts and helps to protect people from hacking, they perform security tests with authorization and break the security to know the security holes in their security systems. These are people who write Anti -Virus programs and spend their time-fighting malware.


3. Gray Hat Hackers

These are all both good and bad guys. This category of hackers hack for both good and bad, in short, they help and harm. Most people fall into this category.




Hierarchy of Hackers

Depends on the skill level of a hacker we can mainly divide them into three types:

  1. Elite Hackers

  2. Intermediate hackers

  3. Script kiddies



1. Elite Hackers

These are the skilled hackers, they're nothing but the programmers. They know how the system, network protocols, the operating system works. They are those who write the various hacker tools and exploits (exploits a chunk of code that takes advantage of a bug or vulnerability in a piece of software that allows you to take control of a computer system), they can change the operating systems, they can write programs like virus, malware, etc.


2. Intermediate hackers

These people usually know about computers, networks, and have enough programming knowledge to know relatively what a script can do, but these people won't develop any tools, viruses, malware, or operating systems, they use pre-developed tools which elite hackers developed.


3. Script kiddies

These are all the low-level hackers, they don’t know any technical things, like how programs, operating systems, networks working, etc. They usually don’t have hacking skills and that they use the tools developed by other hackers (Elite Hackers) without any knowledge of what’s happening behind the scenes. They know simply the way to use it that’s it.



Finally, we reach the question: Why do people hack?


People hack for various purposes, but the most reason is to acquire or access data, and it might be for good or bad reasons. For example, a person is coming to you and saying that his computer operating system is crashed or dead, so I need to get some data from my system. so that you can hack into his system for the data recovery usually using some Linux live cd or Hiren's BootCD. So using this we can access the data from his computer hard disk. It is hacking for good, for bad means hacking to access credit card details, passwords, etc.


How to Start

First of all, you would like to know that there's no trick or overnight process to be a hacker. There are hacking tricks and tools, but hacking is beyond the tricks and tools. Tricks and Tools are only alittle a part of it. If you actually want to understand how to be a hacker, you must follow many things with dedication and practice numerous things. Becoming an excellent hacker isn't easy and it doesn’t happen quickly. You should have creative thoughts a lot. Because there is more than one way to solve a problem, and as a hacker, you encounter any problems. Another huge quality you must have is the will to learn because, without it, you will get nowhere. Because Knowledge is power, Patience is also a must be required because many topics can be difficult to grasp, and only over time will you master them.


Learn Programing


You may ask, "Do i want to learn any programming languages to become a hacker?". The answer is both yes and no, it all depends on your goal. You can be a good hacker without knowing to program, but it is better to learn a programming language because tools have limits and therefore limit how far you can go/what you can do as a hacker. Don't solely rely on tools to do things that you can know and learn. To learn how things work. You should know how it works.

So programming is that the most vital thing that you simply should learn. Like C, Java, PHP, Python, JavaScript, and few other programming languages. If you're good at programming, you'll be ready to create your own scripts and exploits to assist you while hacking. It also helps you in analyzing things. If you are a good programmer, you can easily understand how web applications or software works. It helps you in breaking it.
