About cyber-audit

cyber-audit is a read-only skill for auditing a system against a security advisory. It selects relevant checks, records concrete results in a dated Markdown report, and gives a verdict without making changes outside the audit directory.

Key features

  1. 01Advisory scope identification
  2. 02Relevant checks run in parallel
  3. 03Concrete results recorded in a table
  4. 04Dated Markdown report generation
  5. 05Verdicts with mitigation details

Use cases

  1. 01Checking exposure to a security advisory
  2. 02Auditing installed packages and binaries
  3. 03Recording findings for an audit trail

Install

Copy the command and run it in a terminal.

Hard rules

  • Read-only. No installs, removes, upgrades, restarts, network calls, or file modifications outside ~/Documents/security-audits/.
  • No sudo. Never.
  • One report per invocation. Always end by writing the .md file (even if the verdict is "Not affected" — the audit trail matters).
  • If a check requires a state-changing command, skip it and note "not checked (would require state change)" in the table. Do not run it.

Workflow

  1. Identify scope. Extract from the advisory: package/binary name, affected versions, platform (macOS / Linux / Windows), attack vector (supply chain / RCE / local / network).
  2. Run checks in parallel (Bash tool, multiple calls in one message). Pick relevant checks for the advisory type — don't run all of them.
  3. Build the table as you go. Each row = one check + concrete result (version number, path, "None", "N/A").
  4. Write the report to ~/Documents/security-audits/YYYY-MM-DD-<short-kebab-slug>.md. Use today's date from the environment header.
  5. Tell the user the verdict in one line + path to the report.

# --- Node / npm ecosystem (supply-chain advisories) ---
which npm pnpm yarn; npm root -g; pnpm root -g 2>/dev/null
ls /opt/homebrew/lib/node_modules                                  # global npm
find ~ -maxdepth 8 -type d -name "<pkg>" 2>/dev/null \
  | grep -v -E "(Library/Caches|\.Trash)"                          # installed copies
find ~/Documents ~/Desktop ~/Downloads -maxdepth 8 -type f \
  \( -name "package.json" -o -name "package-lock.json" \
     -o -name "pnpm-lock.yaml" -o -name "yarn.lock" \) 2>/dev/null \
  | xargs grep -l "<pkg>" 2>/dev/null                              # direct + transitive

# --- Python ecosystem ---
which python3 pip pipx uv
pip list 2>/dev/null | grep -i "<pkg>"
find ~/Documents -maxdepth 6 -name "requirements*.txt" -o -name "pyproject.toml" \
  -o -name "poetry.lock" -o -name "uv.lock" 2>/dev/null | xargs grep -l "<pkg>" 2>/dev/null

# --- Homebrew / system binaries ---
brew list --versions <formula> 2>/dev/null
which <binary>; <binary> --version 2>/dev/null

# --- Running processes / listeners (for RCE / network CVEs) ---
pgrep -lf "<binary>"
lsof -iTCP -sTCP:LISTEN -P -n 2>/dev/null | grep "<port>"

# --- LaunchAgents / LaunchDaemons (persistence / autostart) ---
ls ~/Library/LaunchAgents /Library/LaunchAgents /Library/LaunchDaemons 2>/dev/null \
  | grep -i "<vendor>"

# --- Env vars that change exposure (e.g. OLLAMA_HOST, listening addr) ---
launchctl getenv <VAR>; grep -r "<VAR>" ~/.zshrc ~/.zprofile ~/.config 2>/dev/null

# --- VS Code / browser extensions (for IDE-targeted advisories) ---
ls ~/.vscode/extensions 2>/dev/null | grep -i "<ext>"

If the advisory mentions an ecosystem not above (Rust cargo, Go modules, Ruby gems, Docker images, etc.), apply the same pattern: global install path + manifest grep + running processes.

Report template

File: ~/Documents/security-audits/YYYY-MM-DD-<short-kebab-slug>.md

# <Subject> — Audit

**Date:** YYYY-MM-DD
**Host:** the user's MacBook Pro

## <CVEs | Advisory> in scope

- **<ID or source> "<Name>"** — <one-line description>. <Affected versions or scope>.

## Audit results

| Check | Result |
|---|---|
| <Check 1> | <Result> |
| <Check 2> | <Result> |

## Verdict

**<Not affected. | Affected. | Partially affected.>**

- <Rationale bullet 1>
- <Rationale bullet 2>

## Action taken

None — diagnostic only, no files modified, no <packages installed/removed | services started/stopped | firewall rules changed>.

## Follow-ups

- <Actionable item, or "None" if truly nothing>

Match the tone of the existing reports in ~/Documents/security-audits/ — terse, factual, bulleted, no hedging.

Verdict wording

  • Not affected. — package/binary absent, or installed but patched, or not running and not exposed.
  • Affected. — vulnerable version present and reachable by the attack vector.
  • Partially affected. — present but mitigated (e.g. binary installed but service not running, or listener bound to loopback only). Spell out the mitigation in the bullets.

When to break the read-only rule

Never on your own. If the verdict is "Affected", list the remediation command in Follow-ups and stop. The user runs it.

Reference

Existing reports in ~/Documents/security-audits/ show the expected style:

  • a long-form baseline audit report (different format, do not mimic)
  • dated YYYY-MM-DD-*.md advisory reports (this is the format to match)
