Doxing (from dox, abbreviation of documents) or doxxing is the Internet-based practice of researching and broadcasting private or identifying information (especially personally identifying information) about an individual or organization.

The methods employed to acquire this information include searching publicly available databases and social media websites (like Facebook), hacking, and social engineering. It is closely related to Internet vigilantism and hacktivism.

Doxing may be carried out for various reasons, including to aid law enforcement, business analysis, risk analytics, extortion, coercion, inflicting harm, ***harassment, online shaming, ***and vigilante justice.
