haker

Haker is a variant spelling of the English term "hacker," used in some languages to refer to a person skilled in computers, networks, and programming. The term broadly denotes individuals who explore, modify, or manipulate computing systems, often with deep technical knowledge and problem-solving abilities.

The term originates from the verb "to hack," which in computing culture historically meant experimenting or tinkering with systems to understand their behavior. Early usage emerged in academic and hobbyist communities in the mid-20th century and later broadened in popular media.

Hackers are commonly categorized by intent and activity. White hat hackers perform security testing and vulnerability assessments to improve protection. Black hat hackers exploit systems for personal gain, vandalism, or other malicious purposes. Gray hat hackers operate between these extremes, sometimes violating norms without malicious intent but without explicit authorization.

Activities associated with hacking range from software development, security research, and system administration to unauthorized access and data breaches. Ethical hacking and penetration testing are legitimate, regulated activities aimed at strengthening defenses. Unauthorized intrusion, data theft, and the creation of malware are illegal in many jurisdictions.

Hacker culture emphasizes creativity, learning, and technical excellence, embodied in communities, conferences, and open-source projects. Legal and ethical considerations are central to public discussion, and many organizations promote responsible disclosure and certification programs. The impact of hacking spans cybersecurity, privacy, commerce, and national security, making it a key topic in technology policy and law.
