exploitation-phase

exploitation-phase is a skill for Claude Code, Codex from s0ld13rr/pentestcode. It costs 36 tokens per session (749 once invoked), scanned A, original, MIT.

An exploitation-phase checklist for testing confirmed security weaknesses and proving their real impact. It covers public exploits, credential attacks, and evidence such as command output, secrets, or accessed data.

In plain words
What is it for?
Use it to search for known exploits, test approved credentials, reproduce vulnerabilities, gain limited access, and record the evidence needed to mark an issue confirmed.
Why use it?
It separates a possible vulnerability from a demonstrated one, reducing the risk of reporting scanner alerts without proof.

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

exploitation-phase 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Exploitation — Prove Impact, Don't Break Things

Golden rule: the goal is a DEMONSTRATED impact for the report, not maximum damage. Prefer the least destructive proof (file read > RCE > data exfil).

Web → load the matching web-* skill

SQLi (web-sqli), SSTI (web-ssti), SSRF (web-ssrf), LFI (web-lfi-traversal), upload RCE (web-upload-rce), XXE (web-xxe), auth bypass/IDOR (web-auth-bypass-idor), deserialization (web-deserialization). Router + payload index: playbook-webapp.

  • sqlmap --batch --level 3 --risk 2 only after a manual injection point is confirmed.
  • Public PoC for a known CVE: fetch, READ IT, adapt to the exact version — never blind-run exploit binaries.

Network

  • Capture: tcpdump -i eth0 -w cap.pcap 'host X' / Wireshark — creds in cleartext protocols (FTP, HTTP basic, SNMP) are findings on their own.
  • MITM/relay: ARP spoofing only on flat L2 segments with authorization; NTLM relay requires SMB signing disabled (checked in enumeration).
  • Responder + ntlmrelayx are the standard authorized chain: LLMNR/NBT-NS poison → relay to SMB/ADCS/LDAP.
  • Impacket suite covers the rest: GetNPUsers.py (AS-REP), GetUserSPNs.py (kerberoast), secretsdump.py, psexec.py/wmiexec.py (lateral).

Credential attacks — lockout-aware ALWAYS

# Spray: ONE password across MANY users, never the reverse
nxc smb DC -u users.txt -p 'Summer2024!' --continue-on-success
hydra -L users.txt -p 'CommonPass1!' target https-post-form '/login:user=^PASS^:F=invalid'
  • Respect lockout policy (enumerate it via netexec ... --pass-pol first). A locked-out user base = failed test.
  • Cracking offline: hashcat -m 1000 (NTLM), -m 18200 (AS-REP), -m 13100 (TGS), -m 22000 (WPA). John as fallback. Rockyou + rules; custom wordlist from client context (org name, products, local slang).

Wireless

  • Monitor-mode capture → aircrack-ng -w rockyou cap.cap (WPA2 handshake) or PMKID (hcxdumptool).
  • Evil twin / deauth = disruptive; ONLY with written authorization, never on client production SSIDs during business hours.

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.

exploitation-phase is a skill published in the GitHub repository s0ld13rr/pentestcode (921 stars, last pushed 12d ago), licensed MIT. It adds 36 tokens to every session and 749 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
