A hacker is an individual who possesses extensive knowledge of computer systems and programming, using their skills to gain unauthorized access to computers, networks, and data.
Hackers are often associated with malicious activities such as stealing information, spreading malware, or disrupting system operations. However, not all hackers pursue illegal goals. There are also “white hat” or “ethical” hackers who use their expertise to identify vulnerabilities in security systems and help organizations strengthen their defenses.
Depending on their activities, hackers can be classified into the following types:
- White Hat Hackers – cybersecurity professionals who use their skills to identify and fix vulnerabilities in security systems.
- Black Hat Hackers – attackers who exploit vulnerabilities for illegal purposes, such as theft or abuse.
- Gray Hat Hackers – straddle the line between white and black hats, sometimes breaking the law but often with good intentions.
In the past, the term “Cracker” was used to refer to hackers who specialized in software hacking.
Regardless of their motives, hackers’ actions typically involve circumventing security measures, cracking passwords, exploiting software vulnerabilities, and manipulating systems to gain control over them. Therefore, it is crucial to implement robust cybersecurity practices to protect against potential hacking attempts.
