Security Secrets

Review secret detection patterns and scanning workflows. Use for identifying high-signal secrets like AWS keys, GitHub tokens, and DB passwords. Use proactively during all security audits to scan code and history. Examples: - user: "Scan for secrets in this repo" → run high-signal rg patterns and gitleaks - user: "Check for AWS keys" → scan for AKIA patterns and server-side exposure - user: "Audit my .env files" → ensure secrets are gitignored and not committed - user: "Verify secret redaction" → check that reported secrets follow 4+4 format - user: "Scan build artifacts for keys" → search dist/ and build/ for secret patterns

CLI Scanning Commands

# Quick grep scan (fast, high signal)
rg -n "(AKIA[0-9A-Z]{16}|sk_(live|test)_|rk_(live|test)_|pk_(live|test)_|xox[baprs]-|xapp-|xwfp-|gh[pousr]_|github_pat_)" .
rg -n "BEGIN (RSA|EC|OPENSSH|DSA|PGP) PRIVATE KEY" .
rg -n "(?i)(api[_-]?key|secret|token|password)\s*[:=]\s*['\"][^'\"]{8,}" .

# Dedicated scanners (thorough)
gitleaks detect --source . --redact --no-git
semgrep scan --config p/secrets --error
trufflehog filesystem . --only-verified

Files to Prioritize

File Pattern	Risk Level	Why
`.env*`	CRITICAL	Often contains all secrets
`config.js/ts/json`	HIGH	App configuration
`secret`, `credential`	HIGH	Named suspiciously
`docker-compose*.yml`	HIGH	DB passwords, service creds
`.github/workflows/*.yml`	HIGH	CI/CD secrets
`test`, `spec`, `fixture`	MEDIUM	Test data with real creds
`.pem`, `.key`, `*.p12`	CRITICAL	Private keys

Redaction Format

When reporting secrets, MUST always redact:

Original: AKIAIOSFODNN7EXAMPLE
Redacted: AKIA****...****MPLE

Original: sk_test_XXXXYYYYZZZZ11112222
Redacted: sk_****...****2222

MUST show first 4 + last 4 characters only. MUST instruct immediate rotation.
