Comparing Black Hat, Gray Hat, and White Hat Hackers

Nerd Cafe | نرد کافه

White Hat Hacker

A cybersecurity professional who legally and ethically tests systems to identify vulnerabilities, strengthen defenses, and ensure compliance, acting as a trusted defender and risk mitigator.

Black Hat Hacker

An unauthorized actor who exploits system vulnerabilities for personal, financial, or political gain, deliberately bypassing security measures and causing harm to organizational assets and reputation.

Gray Hat Hacker

A hacker who operates in the ambiguous zone between legality and ethics, occasionally exposing vulnerabilities without permission—sometimes improving security, sometimes creating unintended risks.
