WHAT IS HACKING? WHAT WE USE FOR HACKING ? IS IT ILLEGAL ?

What does Hacking mean?

Hacking generally refers to unauthorized intrusion into a computer or a network. The person engaged in hacking activities is known as a hacker. This hacker may alter system or security features to accomplish a goal that differs from the original purpose of the system.

 types of hacking:-

basically hacking is of three type 

1>ethical hacking 

2>black hat hacking

3>grey hat hacking

An ethical hacker (also known as a white hat hacker) is the ultimate security professional. Ethical hackers know how to find and exploit vulnerabilities and weaknesses in various systems—just like a malicious hacker (or a black hat hacker). In fact, they both use the same skills; however, an ethical hacker uses those skills in a legitimate, lawful manner to try to find vulnerabilities and fix them before the bad guys can get there and try to break in.

An ethical hacker’s role is similar to that of a penetration tester, but it involves broader duties. They break into systems legally and ethically. This is the primary difference between ethical hackers and real hackers—the legality.

Black Hat Hackers

Like all hackers, black hat hackers usually have extensive knowledge about breaking into computer networks and bypassing security protocols. They are also responsible for writing malware, which is a method used to gain access to these systems.

Their primary motivation is usually for personal or financial gain, but they can also be involved in cyber espionage, protest or perhaps are just addicted to the thrill of cybercrime. Blackhat hackers can range from amateurs getting their feet wet by spreading malware, to experienced hackers that aim to steal data, specifically financial information, personal information and login credentials. Not only do black hat hackers seek to steal data, but they also seek to modify or destroy data as well.

Grey Hat Hackers

As in life, there are grey areas that are neither black nor white. Grey hat hackers are a blend of both black hat and white hat activities. Often, grey hat hackers will look for vulnerabilities in a system without the owner’s permission or knowledge. If issues are found, they will report them to the owner, sometimes requesting a small fee to fix the issue. If the owner does not respond or comply, then sometimes the hackers will post the newly found exploit online for the world to see.

These types of hackers are not inherently malicious with their intentions; they’re just looking to get something out of their discoveries for themselves. Usually, grey hat hackers will not exploit the found vulnerabilities. However, this type of hacking is still considered illegal because the hacker did not receive permission from the owner prior to attempting to attack the system.

Although the word hacker tends to evoke negative connotations when referred to, it is important to remember that all hackers are not created equal. If we didn’t have white hat hackers diligently seeking out threats and vulnerabilities before the black hats can find them, then there would probably be a lot more activity involving cybercriminals exploiting vulnerabilities and collecting sensitive data than there is now.
