Hi friends, so today I am going to tell you about "Computer Virus". So first let us know about computer virus.
A computer virus is a program which enters without any permission or knowledge of the user.
We must be aware of it as a virus as it has the ability to attach itself into a file and that's how any virus come to our system while downloading games, apps etc. Some of the example are - Pikachu virus, Conficker etc.
Virus affects a computer and destroy it. In the similar way, hackers hack our systems.
About Hacking
Not all hackers are bad, some are good also and in technical terms, are identified by hats. The hats are similar as the cowboys in movies. Let us learn more about them.
Types of hats in hacking
1) White hat hackers => The hackers who are licensed from the government and work for them are white hat hackers. They also protect the internal files and documents from hacking. The current Pegasus spyware was done by white hat hackers.
2) Black hat hackers => Black hat hackers are those who are opposite of white hat hackers. They hack and damage other's computer system and sometimes also hack the government's system which the white hat hackers protects from.
3) Grey hat hackers => Grey hat hacker type falls between white hat hackers and black hats hackers. The difference is, they don’t want to rob people nor want to help people in particular. Rather, they enjoy experimenting with systems to find virus, crack defenses, and generally find a fun hacking experience.
4) Green hat hackers => Green hat hackers are types of hackers who’re learning the ropes of hacking. They didn't hack the system but they are learning to hack.
5) Red hat hackers => Red Hat Hackers are like with Eagle-Eyed Hackers. They are the types of hackers who’re similar to white hackers. The red hat hackers intend to stop the attack of black hat hackers but for a different purpose.
6) Blue hat hackers => Blue Hat Hackers are types of hackers who’re similar to Script Kiddies. The intent to learn is missing. They use hacking as a weapon to gain popularity among their fellow beings. They use hacking to settle scores with their adversaries. Blue Hat Hackers are dangerous due to the intent behind the hacking rather than their knowledge.
