Hacker

A hacker is someone who uses technical skills to access computer systems, networks, or data, often by finding vulnerabilities or weaknesses. While some hackers—called ethical hackers—help organizations improve security by identifying and fixing issues, others engage in malicious activities like stealing information, causing disruptions, or extorting money. Hacking involves understanding computer code, systems, and security measures, and can range from authorized testing to illegal breaches. Overall, hacking is a skillful manipulation of technology that can be used for both constructive and harmful purposes.
