## Project history and usage

favirecon is a Go security reconnaissance CLI that uses favicon hashes to help identify technologies, WAFs, exposed panels, and known services during target recon.

### Project history

The GitHub repository was created in November 2022. The official README centers the tool on a favicon hash database and asks users to open issues when they find new or incorrect hash-to-service associations.

### Adoption history

The README documents installation through Homebrew, Snap, and go install. Homebrew currently tracks the upstream v1.0.3 release archive and also provides a HEAD build path.

### How it is used

favirecon accepts a single URL, a list of target domains, standard input, or CIDR input, and supports concurrency, timeout, rate limiting, proxy, output file, verbose, silent, and JSON output flags.

### Why package nerds care

favirecon is useful to security-focused package-manager users because it packages a bug-bounty reconnaissance technique as a small cross-platform Go CLI with simple shell integration.

### Timeline

- 2022: GitHub repository created.
- 2023: v0.0.1 published on GitHub Releases.
- 2026: v1.0.3 published and tracked by Homebrew.

### Related projects

- The README positions favirecon within infosec and bug-bounty reconnaissance workflows that use favicon.ico hash matching.
