What is hacking
Hacking is the process of attaining access to a computer system or group of computer systems without having official permission or approval. This is achieved through identifying weaknesses in codes or finding backdoor access to exploit its weaknesses to gain access to the computer systems or networks.
Hacking is done through cracking of passwords and codes which gives access to sensitive data that an individual or company would like to keep to themselves. Cracking is the term that specifies the process by which a password or code is obtained. This gives unauthorized access to systems, website, social media sites, email account or an entire LAN network. The person responsible for hacking is known as the HACKER.

With the rise in technology, almost all have access to the world at our fingertips. Now individuals, as well as companies of all scale, use mobiles, computers, and laptops for all their personal and professional use.
Organizations ranging from a start-up to a world-renowned corporation, it is essential to have a seamless flow of information which requires systems like a computer network, Wide Area Network (WAN), domain and website. These networks are under a high-risk exposure to the world of hacking and hackers.
Hacking is a fraudulent act that is generally termed as privacy invasion, stealing corporate/personal data, Data breach, etc. Cybercrime Damages will be $6 Trillion by 2021 and therefore businesses need to protect themselves against such attacks.


Hacking is classified as a Cybercrime. Cybercrime in laymen’s terms can be defined as crimes committed over the internet and some cybercrimes can also be carried out using Mobile phones via SMS and online chatting applications.
There is a long list of illicit and unauthorized activities that are collectively termed as cybercrime. These perform illegal activities that are carried out by the use of computers and networks to spread computer viruses, collecting private data, online bullying, performing unauthorized electronic fund transfers, etc.




Hackers are highly skilled computer programmers with knowledge of how a computer security system works. Depending upon the level of security systems installed the level of difficulty to hack the system changes. There are different types of hackers not just based on the skill and knowledge one possesses but according to the intent of their actions.
The following list classifies hackers, THE GOOD, BAD AND THE UGLY


The term "white hat" in Internet slang refers to an ethical computer hacker. A hacker who gains access to systems with a view to fixing the identified weaknesses. They scan through the protected systems and networks to test, asses their security and perform Penetration Testing and vulnerability.
A white-hat hacker is a computer security specialist who breaks into the system and use their skills to improve security by exposing vulnerabilities before malicious hackers take advantage of these security risks.


BLACK HAT hacker is one who gains unauthorized access to computer systems purely with negative intentions for personal gain, fame or financial benefits. Black hats take the crown as the criminals exploiting the security vulnerabilities in the system. The intent is usually to steal corporate data, violate privacy rights, transfer funds from bank accounts, etc.
They may also release malware that destroys files, holds computers hostage, steals passwords, credit card numbers, and other personal information thus robbing banks, organizations, individuals, financial institutions hundreds of millions of dollars, and invaluable private data.


GREY HAT hacker is one who is in between White Hat hackers (Ethical Hackers) and Black hat hackers. Hackers that break into computer systems without authority with a view to identify weaknesses and reveal them to the system owner.
The gray hat hacker will sometimes violate laws or typical ethical standards but does not have the malicious intent of that of a black hat hacker.


They are classified as a hacker but are not considered as one by many. The person who uses existing computer scripts or codes to hack into computers, lacking any sort of expertise to write a script or code of their own. A non-skilled person who gains access to computer systems using already made tools.
The intent to attack computer systems and networks and deface websites are generally to impress their friends or gain credit in computer-enthusiast communities.


The concept of suicide hackers is the same as suicide bombers. How a suicide bomber kills themselves to harm others is what a suicide hacker does. The hacker knows that they would be caught as a criminal if they hack the system, website or any unauthorized activity that comes under as a cybercrime.
The hackers generally do these for fame, revenge and for money and generally believe they are in the right. They will proceed to carry out hacking attempt even if he/she knows that their identity could be revealed and would be caught.


The hacktivist is like an activist, someone who uses hacking to bring about political and social awareness and change. They would break into systems and infrastructures as a protest or creating awareness, getting attention towards social causes based on their beliefs.
Hacktivists are the opposite of suicide hackers, but the lines get blurred when the activities of each are compared. Mostly they remain anonymous and are considered as vandals of the internet by defacing websites, misusing computers and networks, or any kind of digital space to spread their personal ideologies.


Red hat hackers are the vigilantes of the internet, I personally call them the dark knights as they are technically white hats who stop black hat hacker. Instead of reporting the malicious black hat hackers the red hats mercilessly attack them shut someone down by uploading viruses to computers or devices, DoS and accessing their computer to destroy it from the inside out rendering them useless.
Red hats can be considered as a necessary evil in order to keep the balance on the internet. They use multiple aggressive methods that might force the hackers to need a new computer. Their sole objective is to destroy the effort of every bad hacker and to push the black hat hacker out of business by bringing their entire infrastructure down.
