History of the Term White Hat Hacker

The term "white hat hacker" originated in the early days of computing and hacking culture, stemming from Western movies where the hero typically wore a white hat.

Coined in the 1970s, it referred to ethical hackers who used their technical expertise to uncover vulnerabilities, test systems for security flaws, and protect against cyber threats.
