The repository keeps the older Perl script under scripts/fierce.pl, where the banner identifies Fierce v0.9.9 beta dated March 24, 2007 and credits RSnake with threading and additions by IceShaman. The Python rewrite kept the core reconnaissance idea but modernized the packaging and runtime around Python tooling. The README presents pip installation, direct source checkout, Poetry development setup, pytest testing, flake8 linting, and coverage commands. ### Historique d'adoption fierce belongs to the pre-exploitation reconnaissance layer of security tooling. Its README explicitly frames it as a precursor to tools such as nmap, unicornscan, Nessus, and Nikto, because those scanners are more useful once likely IP space and hostnames are known. The supplied package metadata shows fierce packaged beyond Homebrew, including Debian, Ubuntu, and Nix. That distribution footprint fits a small CLI security utility that penetration testers and defenders can install quickly on Unix-like systems. ### Modes d'utilisation The README examples center on DNS lookups rather than exploitation. Typical use starts with a domain and a subdomain list, then optionally traverses nearby IPs, restricts nearby lookups to selected domains, attempts HTTP connections on discovered names, widens searches across a /24, checks zone-transfer exposure, redirects output to a file, or scans an internal address range against a chosen DNS server. The original description, preserved in the README, is careful about scope: fierce is meant to identify likely targets inside and outside a corporate network through DNS, not to indiscriminately scan the internet or exploit hosts. ### Pourquoi les passionnés de paquets s'y intéressent For package nerds, fierce is a recognizable example of a security tool whose cultural value is larger than its code size: it wraps a focused reconnaissance workflow into a single installable command and carries lineage from the older ha.ckers.org-era Perl security-tool ecosystem into Python 3 packaging. ### Chronologie - 2007: The preserved Perl script identifies Fierce v0.9.9 beta dated March 24, 2007. - Python 3 era: The maintained repository describes itself as a Python 3 conversion to simplify and modernize the codebase. - Packaging note: The README documents pip installation and standard Python development commands. ### Related projects - The project documentation positions fierce before tools such as nmap, unicornscan, Nessus, and Nikto in a reconnaissance workflow. Its operating domain also overlaps with DNS zone-transfer testing and subdomain discovery tools. ### Sources - - ## Notes de sécurité narrow executable package without higher-risk signals. - **Risque Geiger:** vert / faible - narrow executable package without higher-risk signals ## Détails de la base source - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** fierce - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Autres enregistrements de gestionnaires de paquets - Debian apt - fierce - 1.6.0-1: normalized package name match | Debian stable package indexes: fierce from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Domain DNS scanner | https://github.com/mschwager/fierce - Nix - fierce: normalized package name match | nixpkgs package indexes: pkgs/by-name/fi/fierce/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - fierce - 1.5.0-1: normalized package name match | Ubuntu 24.04 LTS package indexes: fierce from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Domain DNS scanner | https://github.com/mschwager/fierce ## Liens liés - [Source-control packages](https://pkg.so/fr/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/fr/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/fr/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Security and crypto packages](https://pkg.so/fr/security-crypto-tools/) - Matched security, identity, cryptography, password, signing, or certificate metadata. - [python@3.14](https://pkg.so/fr/brew/python-3-14/) - Runtime dependency declared by Homebrew. - [findomain](https://pkg.so/fr/brew/findomain/) - Shares pkgdb curated category or tags: cli, dns, reconnaissance, security. - [shuffledns](https://pkg.so/fr/brew/shuffledns/) - Shares pkgdb curated category or tags: cli, dns, reconnaissance, security. - [amass](https://pkg.so/fr/brew/amass/) - Shares pkgdb curated category or tags: cli, dns, reconnaissance, security. - [dnstwist](https://pkg.so/fr/brew/dnstwist/) - Shares pkgdb curated category or tags: cli, dns, security. - [dnsgen](https://pkg.so/fr/brew/dnsgen/) - Shares pkgdb curated category or tags: cli, dns, reconnaissance, security. - [dnsmap](https://pkg.so/fr/brew/dnsmap/) - Shares pkgdb curated category or tags: cli, dns, reconnaissance, security. - [subfinder](https://pkg.so/fr/brew/subfinder/) - Shares pkgdb curated category or tags: cli, reconnaissance, security. - [theharvester](https://pkg.so/fr/brew/theharvester/) - Shares pkgdb curated category or tags: cli, reconnaissance, security. - [recon-ng](https://pkg.so/fr/brew/recon-ng/) - Both packages touch the same language runtime or ecosystem.
