A hacker is an individual skilled in computer programming and network systems who uses their technical knowledge to overcome or manipulate computer and network security. There are different types of hackers based on their intentions and actions:

  1. Ethical hackers (white-hat hackers): These are professional security experts who use their hacking skills for good, to help organizations identify vulnerabilities in their systems and strengthen security measures. They perform these actions legally and ethically.
  2. Black-hat hackers: These individuals use their skills maliciously to breach computer systems without authorization, typically for personal or financial gain. They are responsible for a range of cyber crimes, including data breaches, identity theft, and distribution of harmful software.
  3. Grey-hat hackers: These individuals fall somewhere between white and black-hat hackers. They might hack into systems without authorization, but not for personal or financial gain. Instead, they often disclose the vulnerabilities they find to the system owner, or to the public if the owner fails to fix the problem.

It’s important to note that while the term “hacker” is often used to describe cyber criminals, not all hackers have malicious intent. Many work to protect systems and data from potential threats.
