Anubis is a command-line security reconnaissance framework designed for subdomain enumeration and attack surface mapping. It functions as a utility for security professionals to identify, catalog, and visualize the external digital footprint of an organization by discovering all subdomains associated with a target domain.
The tool distinguishes itself through a modular resolver pipeline that integrates passive reconnaissance from third-party security APIs and public certificate transparency logs. It combines this data with active discovery methods, including recursive DNS brute-forcing and algorithmic pattern-based permutation generation, to uncover hidden infrastructure that is not publicly indexed.
To maintain efficiency during large-scale assessments, the software utilizes asynchronous concurrent scanning to perform thousands of simultaneous DNS lookups. A built-in deduplication engine normalizes and filters these results to provide a clean, unique list of discovered assets for further vulnerability research.
