insecure-source-code-management

insecure-source-code-management is a skill for Claude Code, Codex from ShulkwiSEC/bb-huge. It costs 47 tokens per session (1,441 once invoked), scanned A, a copy of insecure-source-code-management, MIT.

A security-testing guide for finding exposed source-control folders, backup files, and configuration files on websites. Source-control systems such as Git and Subversion keep project history and may contain code, internal URLs, or secrets.

In plain words
What is it for?
Use it during authorized web reconnaissance to check paths such as .git, .svn, .env, and common backup files, then document safely exposed information.
Why use it?
It helps identify files that were accidentally published and could reveal application code, credentials, or deployment details.

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 A, and why

insecure-source-code-management scanned grade A with 0 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 7d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SKILL: Insecure Source Code Management

AI LOAD INSTRUCTION: This skill covers detection and recovery of exposed version-control metadata, common backup artifacts, and related misconfigurations. Use only in authorized assessments. Treat recovered credentials and URLs as sensitive; do not exfiltrate real data beyond scope. For broad discovery workflow, cross-load recon-for-sec and recon-and-methodology when those skills exist in the workspace.

0. QUICK START

High-value paths to probe first (GET or HEAD, respect rate limits):

/.git/HEAD
/.git/config
/.svn/entries
/.svn/wc.db
/.hg/requires
/.bzr/README
/.DS_Store
/.env

Routing note: quickly probe these paths first; for full recon workflow, load methodology from recon-for-sec and recon-and-methodology before deeper testing.


1. GIT EXPOSURE

Detection

  • /.git/HEAD — valid repo often returns plain text like:
ref: refs/heads/main
  • /.git/config — may expose remote.origin.url, user identity, or embedded credentials.
  • /.git/index, /.git/objects/ — partial object store access enables reconstruction with the right tools.

403 vs 404

  • 404 — path likely absent or fully blocked at the edge.
  • 403 on /.git/ — directory may exist but listing is denied; still try direct file URLs:
/.git/HEAD
/.git/config
/.git/logs/HEAD
/.git/refs/heads/main

A 403 on the directory plus 200 on HEAD strongly indicates exposure.

Recovery tools (open source)

  • arthaud/git-dumper — dumps reachable .git tree when individual files are fetchable.
  • internetwache/GitTools — Dumper, Extractor, Finder modules for partial/corrupt dumps.
  • WangYihang/GitHacker — alternative recovery when standard dumpers miss edge cases.

Key files to prioritize

Path Why it matters
.git/config Remotes, credentials, hooks paths
.git/logs/HEAD Commit history, reflog-style leakage
.git/refs/heads/* Branch tips, commit SHAs
.git/packed-refs Packed branch/tag refs
.git/objects/** Object blobs for reconstruction

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.
