pentest-opsec-evidence

pentest-opsec-evidence is a skill for Claude Code from fatihkan/badi. It costs 65 tokens per session (1,531 once invoked), scanned A, original, MIT.

A guide to reducing a security tester's visible footprint and preserving test evidence. OPSEC means operational security: controlling identifying details and activity patterns; chain of custody records who handled evidence and when.

In plain words
What is it for?
Use it to plan bastions and source connections, manage browser and tool fingerprints, retain engagement logs, and document evidence handling and storage.
Why use it?
It helps an authorised engagement avoid unnecessary attribution or disruption and keeps logs and captured material credible for later review.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

pentest-opsec-evidence scanned grade A with 1 finding 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 4d 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.

pentest-opsec-evidence

Operator OPSEC + engagement evidence handling. Minimizing the operator's footprint on the target during a pentest + storing evidence at legal grade.

Triggers

  • "assess OPSEC"
  • "hide source IP"
  • "burner infrastructure"
  • "fingerprint hygiene"
  • "evidence chain of custody"
  • "log retention policy"

Operator Identity Hygiene

Source IP Design

1. Burner cloud VM (AWS / DO / Linode)
   - Account: pentest-firm name, real name (do not hide the legal account)
   - VM: single engagement, shut down at the end
   - Region: pick a region the client can observe

2. Residential proxy (selective use)
   - Use without legal authorization is wrong (even Tor carries attribution potential)
   - For testing within a bug bounty / authorized engagement

3. Bastion + jump host
   - Operator <-> Bastion (own) <-> Cloud VM <-> target
   - Bastion log: timestamp + command + operator

Browser/HTTP Fingerprint Hygiene

# Burp / proxy config
- User-Agent: realistic, version-current
- Accept-Language: target locale
- JA3 fingerprint: common browser (Chrome 119 default)

# Tool customization
nmap --max-rate 100 --randomize-hosts
curl -A "Mozilla/5.0 (compatible)" --resolve ...

DNS / SNI Hygiene

# DNS over HTTPS (DoH)
# When making DNS queries toward the target, use 1.1.1.1 DoH instead of your own ISP DNS

# SNI: cloudfront / cloudflare cover behind
# (for authorized use only — within a legal framework)

Tooling Footprint

Tool Default Footprint Stealthy Alternative
nmap (default) -sC -sV LOUD -sT -sV --top-ports 100 --max-rate 100
sqlmap (default) Many requests, banner --random-agent --delay 2 --threads 1
BloodHound (default) Mass LDAP --throttle 30 --jitter 20
ffuf 1000 req/s -t 5 -p 1
nuclei All templates -tags sqli,xss only

Burner Infrastructure

Per engagement:
1. Set up a VM (cloud / your own VPS)
2. Separate SSH key pair (engagement-specific)
3. Tooling stack install (Kali Light / Parrot)
4. Engagement end: snapshot + destroy
5. Snapshot: encrypted (BitLocker / VeraCrypt) cold storage

Persistent:
- Bug bounty researcher: dedicated workstation (1)
- Pentest firm: per-customer VM template
- Red team operator: 3 tiers (recon/exploit/post-ex isolated)

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.
