## What it does

The skill runs targeted pattern checks for provider key prefixes, including Stripe, AWS, GitHub, and Slack tokens. It searches tracked files with `git ls-files` to avoid `node_modules`. The audit inspects Git history. It also inspects Docker image layers and frontend bundles that expose environment variables.

The second half reviews how the project stores credentials. It audits patterns against a security hierarchy, contrasting unencrypted `.env` files with managers like Doppler or AWS Secrets Manager. When a leak appears, the agent guides triage. It helps verify live keys, check access permissions, and trace exposure timelines.

Rewriting history with `git filter-repo` before key rotation is useless. Forks and local clones still keep the secret. Always rotate the credential first. To operate, the skill requires Bash, Read, Grep, and Glob.

## Requirements
- Works with: AWS

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill secrets-audit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/secrets-audit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/secrets-audit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill secrets-audit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/secrets-audit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill secrets-audit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/secrets-audit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install briiirussell/cybersecurity-skills secrets-audit
```

2. **Manually: put the files in place**
- File: `.github/skills/secrets-audit/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill secrets-audit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/briiirussell/cybersecurity-skills --path skills/secrets-audit
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/secrets-audit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill secrets-audit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/briiirussell/cybersecurity-skills/tree/HEAD/skills/secrets-audit/SKILL.md

## When to use it
- scan source code and Git history for exposed API keys
- detect secrets embedded in Docker image layers and CI logs
- triage leaked credentials and plan zero-downtime rotation
- audit secrets-management setups against cloud vaults and workload identity

## Example prompts
- Scan this repo and commit history for exposed Stripe and AWS credentials
- Run a secrets audit using gitleaks and identify any leaked tokens
- Review our secrets-management setup and recommend a migration from .env files

# Secrets Audit — Credential Exposure and Secrets-Management Review

Two halves: (1) find secrets that have already leaked into source, history, or artifacts, and (2) audit the secrets-management posture that determines whether future leaks happen.

Most secret leaks aren't "we forgot to redact" — they're "we never had a system, so every developer made up their own approach." This skill covers both the cleanup and the prevention.

Cross-references: `dependency-audit` (CI-related secrets risk in build-time exposure), `iam-audit` (workload identity federation as the alternative to long-lived keys), `owasp-audit` A02 (in-source secret patterns).

## Part 1 — Find leaked secrets

### Provider key prefixes (high-confidence patterns)

The most useful first sweep is grep against known provider key prefixes. False positives are low and matches are almost always real.

```bash
# Stripe
grep -rE "(sk_live_|sk_test_|rk_live_|whsec_)[A-Za-z0-9]{20,}" . \
  --include="*.{js,ts,jsx,tsx,py,rb,go,java,php,sh,env,yml,yaml,json}"

# AWS access keys
grep -rE "(AKIA|ASIA)[A-Z0-9]{16}" .

# AWS secret keys (40 chars, base64-y) — high FP rate, use with caution
grep -rE "[A-Za-z0-9/+=]{40}" . --include="*.env*" --include="*.json"

# GitHub
grep -rE "gh[pousr]_[A-Za-z0-9]{36}" .

# Google Cloud API key + service-account JSON
grep -rE "AIza[A-Za-z0-9_-]{35}" .
grep -rln '"type": "service_account"' . --include="*.json"

# Slack
grep -rE "xox[baprs]-[A-Za-z0-9-]+" .

# OpenAI / Anthropic
grep -rE "sk-[A-Za-z0-9]{32,}" .
grep -rE "sk-ant-[A-Za-z0-9_-]{90,}" .

# Generic high-entropy strings in env files
grep -rE "^[A-Z_]+=[A-Za-z0-9/+=]{32,}$" . --include="*.env*"
```

For full repo coverage, use `git ls-files` to scope to tracked files and avoid `node_modules`:

```bash
git ls-files | xargs grep -lE 'sk_live_|ghp_|AKIA[A-Z0-9]{16}|sk-ant-|AIza[A-Za-z0-9_-]{35}' 2>/dev/null
```

### Tooling

| Tool | Use |
|---|---|
| `gitleaks detect` | Fast, low FP, run as pre-commit and in CI; supports custom rules |
| `trufflehog git file://.` | Verifies findings against the real API (high confidence) |
