🧩 The main categories
- White hat: works ethically to test and improve systems.
- Black hat: breaks into systems for profit or harm.
- Grey hat: acts between ethics and legality.

Warning: any group can use phishing and stolen credentials. Your best defense is hardening login security, not trying to “identify” the attacker.
🛡️ White hat hackers
White hat professionals perform authorized security testing, penetration testing and vulnerability assessments to help organizations fix weaknesses.
💥 Black hat hackers
Black hat actors aim for unauthorized access, data theft, fraud, malware distribution or service disruption. In 2026, their favorite path for individuals is often account takeovers via phishing and credential reuse.
- phishing and social engineering
- malware deployment
- credential stuffing and brute force attempts
- scam infrastructure and botnets
🧪 Grey hat and script kiddies
Grey hat hackers may exploit vulnerabilities without permission to demonstrate impact. Script kiddies typically use existing tools and tutorials.
Even when “intent” is unclear, the behavior can harm you, because the methods overlap with mainstream scams.
📣 Hacktivists
Hacktivists target organizations or platforms to send messages. Risks can include leaks and disruption, but individual users usually face secondary impacts through phishing and “news” scams.
