hakers

Hakers, or hackers in English, are individuals who use computer skills to explore, modify, or gain access to digital systems. The term covers a wide range of actors—from security researchers who test systems with permission to criminals who exploit vulnerabilities. In common usage, hacking can imply illegal activity, but many describe themselves as hackers in a neutral sense of technical skill.

Hackers can be categorized by intent: white hat hackers perform authorized penetration testing and security research; black hat hackers break into systems for theft, disruption, or other malfeasance; gray hat hackers fall somewhere in between, often probing systems without explicit permission but not always with malicious aims. Other groups include hacktivists, script kiddies, and state-sponsored actors.

Historically, hacking emerged in the 1960s and 1970s among researchers and hobbyists, with rapid growth alongside the spread of the internet in the 1990s. Security communities formed around responsible disclosure, CERTs, and bug bounty programs to reward vulnerability reporting and improve defenses.

Impact varies widely: hackers can drive innovations in cybersecurity and raise awareness of weaknesses, but breaches can cause financial loss, privacy harm, and infrastructure disruption. Legal frameworks criminalize unauthorized access and prescribe penalties; many jurisdictions encourage ethical testing, required disclosures, and coordinated vulnerability handling.

Defenses focus on prevention and response: regular software updates, secure coding practices, access controls, monitoring and anomaly detection, security audits, and clearly defined responsible-disclosure processes. See also: cybersecurity, bug bounty, hacker culture.
