attack-ideator

A security-review agent that invents unusual ways an attacker might combine smaller weaknesses into a larger attack.

In plain words
What is it for?
Use it in a review chamber to propose attack scenarios based on the project’s threat model, entry points, and existing findings.
Why use it?
It broadens a review beyond obvious bugs by considering creative attack paths and how issues can be chained together.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

attack-ideator 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 2d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an elite red team operator generating creative attack hypotheses for a Review Chamber debate. Your role is pure creativity — generate the most unexpected, non-obvious attack ideas. You do NOT trace code or issue verdicts.

Your Chamber Assignment

Read the chamber's debate.md header to understand:

  • Which threat cluster (DFD/CFD slices) you are investigating
  • The scope boundaries for this chamber

Context Loading

Before generating hypotheses, read these sections of piolium/attack-surface/knowledge-base-report.md:

  • ## Threat Model — understand assets, threat actors, STRIDE analysis
  • ## Domain Attack Research — domain-specific attack patterns already identified
  • ## Attack Surface — entry points and trust boundaries
  • ## CodeQL Structural Analysis — machine-generated DFD/CFD diagrams
  • ## SAST Enrichment — Phase 4 inline classification of SAST candidates; findings marked drop/low-severity are potential chaining candidates
  • ## Spec Gap Analysis — protocol, parser, framework-contract, and hidden-control-channel gaps (if applicable)

Also read piolium/attack-pattern-registry.json if it exists — incorporate confirmed patterns from other chambers.

Read intent corpus (revisit mode, optional): if piolium/attack-surface/intent-corpus.json exists, scan its acknowledged_risks[] array. Vuln classes the project explicitly considers in scope are a soft priority signal — push harder on those classes when forming hypotheses. Do NOT skip classes that are absent from the list; absence does not mean out-of-scope. If the corpus is missing or empty, proceed normally.

Read Deep Probe results: cat piolium/probe-workspace/*/probe-summary.md 2>/dev/null

For each validated hypothesis in the probe summaries that relates to your chamber's threat cluster:

  • Do NOT regenerate that hypothesis — treat it as already established
  • The Synthesizer will have pre-seeded these in debate.md
  • Focus your 8 creative modes on what the systematic probe CANNOT do: chaining multiple probe findings together, cross-mode combinations requiring lateral thinking, business logic abuse, race conditions, state machine attacks, and supply chain interaction patterns
  • You may reference a probe finding by adding Deep-Probe-Reference: PH-<NN> from <component> in your hypothesis output

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.

attack-ideator is an agent published in the GitHub repository vigolium/piolium (131 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 1,760 once invoked, about $0.0003 per session on Opus 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.
