detecting-exposed-secrets-files

Probe a target for accidentally-served secret-bearing files in the web root — .git/, .env, .DS_Store, backup files, database dumps, key files, CI configs, IDE configs. Use when: post-deploy verification on a new release, or SOC2 auditor asked "what's reachable in the web root that shouldn't be," or a bug-bounty report hints at a leaked file. Threshold: any of the canonical 40+ paths returns 200 OR returns a body matching the expected fingerprint of the file type (e.g., .git/HEAD returns content starting with ref: or a 40-char hex SHA). Trigger with: "check exposed files", "git directory exposure", "env file leak", "backup file scan".

# Detecting Exposed Secrets Files

## Overview

The single highest-value pentest probe per HTTP request. A `.git/config`
disclosure leaks repo URL + credentials embedded in remote URLs. A `.env`
disclosure leaks every API key the app has. A `backup.sql` disclosure
leaks the entire database. These are not "weak crypto" findings that need
a chained exploit. They are direct, immediate compromise.

The probe set is the canonical 40+ paths web servers commonly expose by
accident: VCS directories (`.git/`, `.svn/`, `.hg/`), dotenv files,
OS metadata (`.DS_Store`), database dumps, archive files, IDE configs,
CI configs, and key files. Each is fingerprinted to distinguish a true
