pentest-threat-model

pentest-threat-model is a skill for Claude Code from fatihkan/badi. It costs 63 tokens per session (1,714 once invoked), scanned A, original, MIT.

A structured method for thinking through how a system could be attacked. It covers STRIDE, DREAD, attack trees, data-flow diagrams, and the MITRE ATT&CK catalogue of attacker techniques.

In plain words
What is it for?
Use it to map data flows and trust boundaries, list possible threats, score their risk, and organise them against known attack techniques.
Why use it?
It helps teams find security risks during design reviews, before those risks become expensive defects or incidents.

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-threat-model 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 3d 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.

pentest-threat-model

System threat modeling — STRIDE, DREAD, attack tree, DFD. Used at engagement start or in a design review.

Triggers

  • "create a threat model"
  • "STRIDE analysis"
  • "DREAD scoring"
  • "draw an attack tree"
  • "data flow diagram"
  • "MITRE ATT&CK matrix"

STRIDE (Microsoft)

Letter Threat Counter Property
S Spoofing identity Authentication
T Tampering with data Integrity
R Repudiation Non-repudiation
I Information disclosure Confidentiality
D Denial of service Availability
E Elevation of privilege Authorization

Apply STRIDE to every DFD element (Process, Data Store, Data Flow, Trust Boundary).

DREAD Scoring

Dimension 1 (Low) 5 (High) 10 (Critical)
Damage Minimal Major Catastrophic
Reproducibility Hard Sometimes Trivial
Exploitability Hard Moderate Trivial (script)
Affected users Few Many Most
Discoverability Hidden Apparent Public docs

Total: 50 max. High = high risk.

DFD Structure

[External Entity] --> ((Process)) --> [Data Store]

                          |
                   ((Internal Service))

Components:

  • External Entity (square): user, 3rd party API
  • Process (circle): web server, microservice
  • Data Store (cylinder): database, cache
  • Data Flow (arrow): request/response
  • Trust Boundary (dashed line): VPC boundary, network zone

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.
