pentest-secrets-exposure

pentest-secrets-exposure is a skill for Claude Code, Codex from jd-opensource/JoySafeter. It costs 32 tokens per session (679 once invoked), scanned B, original, Apache-2.0.

A search for exposed secrets and sensitive information in source code, Git history, configuration files, software artifacts, and error messages. Secrets include API keys, passwords, signing keys, and database credentials.

In plain words
What is it for?
Use it to scan repositories and commit history, probe authorized websites for exposed configuration files, detect secrets in artifacts, and test error handling for information leaks.
Why use it?
It helps find credentials that were accidentally committed, left in public files, included in backups, or revealed through overly detailed errors.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

pentest-secrets-exposure scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Harvests environment variablesmediumData exfiltration

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

6. **Client-Side Bundle Analysis**: Extract API keys from JS bundles, source maps exposing server code, hardcoded tokens in mobile packages.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Pentest Secrets Exposure

Purpose

Spans multiple unchecked WSTG categories — CONF-03/04 (sensitive files, backups), INFO-05 (info leakage), ERRH-01/02 (error handling, stack traces). Shannon's pre-recon focuses on architecture, not systematic secrets discovery.

Prerequisites

Authorization Requirements

  • Written authorization with source code access scope (if white-box)
  • Git repository access for history mining (if applicable)
  • Target URL list for exposed file probing

Environment Setup

  • TruffleHog for git history secret scanning
  • GitLeaks for pattern-based secret detection
  • Semgrep with secrets ruleset
  • nuclei with exposure templates

Core Workflow

  1. Source Code Secrets: Scan for hardcoded API keys, DB credentials, JWT signing keys, encryption keys using pattern + entropy detection.
  2. Git History Mining: Search all commits for secrets added then removed. Check force-pushed branches. Analyze .gitignore for sensitive patterns.
  3. Exposed Config Files: Probe for .env, .git/config, .DS_Store, wp-config.php, application.yml, docker-compose.yml with credentials (WSTG-CONF-03/04).
  4. Error Handling Disclosure: Trigger stack traces, debug pages, verbose errors revealing internal paths, DB schemas, framework versions (WSTG-ERRH-01/02).
  5. Backup & Unreferenced Files: .bak, .old, .swp, ~files, editor temp files, DB dumps, log files with sensitive data.
  6. Client-Side Bundle Analysis: Extract API keys from JS bundles, source maps exposing server code, hardcoded tokens in mobile packages.
  7. Secret Validation: Test each discovered credential for active access, document scope, assess blast radius.

WSTG-CONF-03 Test File Extensions Handling for Sensitive Info
WSTG-CONF-04 Review Old Backup and Unreferenced Files
WSTG-INFO-05 Review Webpage Content for Information Leakage

WSTG-ERRH-02 Test Stack Traces

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pentest-secrets-exposure is a skill published in the GitHub repository jd-opensource/JoySafeter (307 stars, last pushed 4d ago), licensed Apache-2.0. It adds 32 tokens to every session and 679 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (harvests environment variables, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
