pentest-exploit-chain

pentest-exploit-chain is a skill for Claude Code from fatihkan/badi. It costs 57 tokens per session (1,556 once invoked), scanned A, original, MIT.

An analysis guide for linking separate security findings into a multi-step attack path. It shows how individually limited weaknesses can combine to reach greater access or impact, using common attack-chain models.

In plain words
What is it for?
Use it to map reconnaissance through compromise and later actions, assess how findings can be chained, and compare the likely stealth and impact of different attack paths.
Why use it?
It helps teams judge real-world risk instead of treating every vulnerability as an isolated item with no connection to the others.

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-exploit-chain 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 yesterday.

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.

pentest-exploit-chain

Chaining individual low-to-medium severity findings into a full compromise chain. The highest value-add of engagement intelligence — human analysis only.

Triggers

  • "can these findings be chained"
  • "draw the kill chain"
  • "low + medium = critical"
  • "attack path simulation"
  • "stealth + impact score"

Lockheed Cyber Kill Chain (7 step)

1. Reconnaissance       — OSINT, port scan
2. Weaponization        — exploit + payload combine
3. Delivery             — phishing, drive-by, USB
4. Exploitation         — vulnerability trigger
5. Installation         — persistent foothold
6. Command & Control    — beacon
7. Actions on Objectives — data exfil, destruction, ransom

Chain Analysis Methodology

1. List all findings (low + medium + high)
2. For each finding: input requirement, output privilege/access
3. Match: output of finding A, input of finding B
4. Draw the path of steps (DAG)
5. Shortest path -> max impact
6. A stealth score (1-5) per step
7. Total stealth + impact -> chain rank

Stealth Scoring (1-5)

Score Type Detection Likelihood
1 Loud EDR/SIEM auto block/alert
2 Noisy Caught when a SOC analyst reviews it in 5 min
3 Moderate Default rule insufficient, hunt query needed
4 Quiet Only sophisticated hunt + threat intel
5 Stealth Undetectable (zero-day, signed bin)

Impact Scoring (1-5)

Score Type Impact
1 Recon Information gathering (no data disclosure)
2 Limited Single account compromise
3 Local Single system compromise
4 Lateral Multiple systems / DB access
5 Catastrophic DA, ransomware, mass exfil

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.
