what is hacking ???
i am hacker Hacking refers to activities that seek to compromise digital devices, such as computers, smartphones, tablets, and even entire networks. And while hacking might not always be for malicious purposes, nowadays most references to hacking, and hackers, characterize it/them as unlawful activity by cybercriminals—motivated by financial gain, protest, information gathering (spying), and even just for the “fun” of the challenge.
Many think that “hacker” refers to some self-taught whiz kid or rogue programmer skilled at modifying computer hardware or software so it can be used in ways outside the original developers' intent. But this is a narrow view that doesn't begin to encompass the wide range of reasons why someone turns to hacking. (For an in-depth look at hackers,
Hacking is typically technical in nature (like creating malvertising that deposits malware in a drive-by attack requiring no user interaction). But hackers can also use psychology to trick the user into clicking on a malicious attachment or providing personal data. These tactics are referred to as “social engineering.”
In fact, it's accurate to characterize hacking as an over-arching umbrella term for activity behind most if not all of the malware and malicious cyberattacks on the computing public, businesses, and governments. Besides social engineering and malvertising, common hacking techniques include:
Botnets
Browser hijacks
Denial of service (DDoS) attacks
Ransomware
Rootkits
Trojans
Viruses
Worms
As such, hacking has evolved from teenage mischief into a billion-dollar growth business, whose adherents have established a criminal infrastructure that develops and sells turnkey hacking tools to would-be crooks with less sophisticated technical skills
Types of Hackers
Hackers can be classified into three different categories:
- Black Hat Hacker
- White Hat Hacker
- Grey Hat Hacker

Black-hat Hackers are also known as an Unethical Hacker or a Security Cracker. These people hack the system illegally to steal money or to achieve their own illegal goals. They find banks or other companies with weak security and steal money or credit card information. They can also modify or destroy the data as well. Black hat hacking is illegal.

White Hat Hacker
White hat Hackers are also known as Ethical Hackers or a Penetration Tester. White hat hackers are the good guys of the hacker world.
These people use the same technique used by the black hat hackers. They also hack the system, but they can only hack the system that they have permission to hack in order to test the security of the system. They focus on security and protecting IT system. White hat hacking is legal.
Gray Hat Hacker
Gray hat Hackers are Hybrid between Black hat Hackers and White hat hackers. They can hack any system even if they don't have permission to test the security of the system but they will never steal money or damage the system.
In most cases, they tell the administrator of that system. But they are also illegal because they test the security of the system that they do not have permission to test. Grey hat hacking is sometimes acted legally and sometimes not.
