Hacker – is an expert in computer systems who is able to identify and exploit vulnerabilities in those systems.
Originally, the term meant an extremely skilled programmer, but now it is often associated with illegal activities.
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.
