Dark Net
Noun · Security & Infosec
Definitions
A part of the internet reachable through overlay networks such as Tor or I2P that hide service location and user identity rather than through normal public browsing alone. In security contexts it often refers to anonymous forums, markets, and hidden services.
In plain English: Online services and communities that operate through anonymity networks.
Example: "The stolen data was advertised first on a dark net forum before appearing on clear-web leak sites."
