The term dox derives from the slang dropping dox, which, according to wired contributor mat honan, was an old-school revenge tactic that emerged from hacker culture in 1990s. Doxed is a slang term used to describe the act of revealing someone's personal information, such as their full name, address, phone number, or other sensitive data, without their consent. This doxing meaning involves taking specific information about someone and then spreading it around the internet or via some other means of getting it out to the public.

Doxing is intentionally designed to violate your sense of security and cause you to panic, lash out, or shut down.
