Doxing, also spelled doxxing, is the act of publicly revealing personally identifiable information about an individual or organization, usually via the internet, without their consent and with malicious intent. This information can include the victims real name, home address, workplace, phone number, financial information, and other personal details. The term "doxing" comes from the word "documents" and refers to compiling and releasing a dossier of personal information on someone.

Doxing can be carried out for various reasons, including online shaming, extortion, vigilante aid to law enforcement, and hacktivism. Once people have been exposed through doxing, they may be targeted for harassment through methods such as actual harassment in person, fake signups for mail subscriptions, pizza deliveries, bombarding the address with letters, or through "swatting".

Doxing is a form of online harassment that violates privacy and can put people in uncomfortable and even dangerous situations. It is a standard tactic of online harassment and has been used by people associated with the Gamergate and vaccine controversies. Doxing is illegal if someone uses illegal means to capture the information or if they use the information to commit a crime such as identity theft or financial crimes.

If you are doxed, you can take steps to protect yourself, such as contacting the website or platform where the information was posted and requesting that it be removed, contacting law enforcement, and taking steps to secure your online accounts and personal information.
