Updated on August 22, 2025, by Xcitium

Have you ever wondered what is doxing and why it’s making headlines in cybersecurity circles? Doxing—short for “dropping documents”—is the act of collecting and publicly exposing personal or sensitive information without consent.

While it originally emerged in online forums, doxing has become a serious cybersecurity threat for individuals, businesses, and executives. According to the Pew Research Center, nearly one in five Americans have experienced severe online harassment, with doxing among the most damaging tactics. For IT managers and CEOs, understanding doxing is essential for protecting both employees and corporate reputation.

This guide explores what doxing is, how it works, its consequences, and strategies to prevent it.

What is Doxing?

Doxing is the deliberate act of gathering, publishing, or leaking sensitive personal data online. Attackers typically release information such as names, addresses, phone numbers, or even financial records to harass, intimidate, or cause harm.

Key Characteristics of Doxing:

Involves non-consensual disclosure of private data.
Aims to intimidate, harass, or damage reputations.
Can target individuals, companies, or entire organizations.
