Hackers (entities)

Hackers are individuals or groups who use their technical skills to access computer systems, networks, or data—often without permission. Some hackers structure their activities around exploring and improving security (white-hat hackers), while others aim to exploit vulnerabilities for personal gain, harm, or disruption (black-hat hackers). There are also those who test security without malicious intent (gray-hat hackers). These entities operate through various methods such as exploiting weaknesses, social engineering, or malware. Their actions can lead to data breaches, financial loss, or compromised privacy, making cybersecurity an essential concern for individuals and organizations alike.
