Develop proof-of-concept exploits against a mock retail-banking agent, then **prove that
specific guardrails close each one** — end to end, from POC through regression test.
<br/>**Build the attack only to prove the defense.**

</div>

> 🔒 **Defensive research only.** The single target is the bundled mock agent; all data is
> synthetic. Every exploit ships with the control that blocks it and a regression test that
> keeps it closed. See [SECURITY.md](SECURITY.md).

> 📖 **New here?** Start with the **[guided walkthrough](docs/WALKTHROUGH.md)** — a narrated tour of
> what the range does, how to run it, and what each output means — or the **[short paper](docs/whitepaper.md)**
> for the research framing (incl. a real-model exploit→block).

**Modeled attack surfaces:** on the **single-agent** surface — **indirect prompt injection** via
retrieved documents, **data poisoning** of the trusted knowledge store, **excessive agency / tool
misuse**, **system-prompt leakage**, **unsafe output handling**, **vector/embedding weakness**
(cross-session retrieval), **unbounded consumption** (tool-budget exhaustion), **supply chain**
(malicious third-party tool), and **multimodal injection** (an instruction hidden in an uploaded
image's OCR text); and on a **multi-agent** surface (`target/multi_agent.py`) — **insecure
inter-agent communication** (forged authorization), **rogue agent** (a sub-agent exceeding least
privilege), **cascading failures** (an unbounded inter-agent escalation storm), and **unexpected
code execution** (formula injection into a compute sub-agent, modeled with zero real execution).
That is full OWASP LLM Top 10 coverage **and the full OWASP Agentic Top 10 (ASI01–ASI10)**. Surfaces
and findings are mapped to OWASP LLM Top 10, both OWASP agentic schemes (Threats & Mitigations
T1–T15 and the 2026 Top 10 for Agentic Applications ASI01–ASI10), MITRE ATLAS, and NIST AI RMF below.

## Mitigation-validation results

The point of the range: each POC must **land with controls off and fail with controls on.**

*Regenerated on each run. Thirteen scenarios are dedicated POC+control pairs covering the **full
OWASP LLM Top 10** (LLM01/03/04/05/06/07/08/10 as primary risks, plus a **multimodal** input surface
under LLM01), **all 10** once impact tags (LLM02, LLM09) are counted, **and the full OWASP Agentic
Top 10 (ASI01–ASI10)** — the four multi-agent scenarios close ASI05/07/08/10. The Agentic column
carries both OWASP agentic schemes — the "Agentic AI — Threats and Mitigations" taxonomy (T1–T15)
and the 2026 "Top 10 for Agentic Applications" (ASI01–ASI10); a cell is **blank** where no honest
mapping exists in either. **AIRQ** (a heuristic defined for this project, not an external standard; AS = Attack Surface,
BR = Blast Radius, DC = Defense Controls) is an **illustrative analyst heuristic for
prioritization, not a calibrated metric** — the controls-on DC is the control's *asserted* strength, so "High → Medium"
is the intended mitigation effect, not a measured residual-risk number. ATLAS rows are
closest-fit (see the scorecard's Notes). Full matrix in `results/scorecard.md`.*

### Strategy-sweep attacker

`python -m finagent_redrange auto` turns an attacker loose on an objective ("extract the agent's
hidden system prompt"). Two planners share one seam (`attacker/engine.py`): the default
**`--planner sweep`** runs a deterministic fixed product of seed payloads × transforms (base64,
role-play, crescendo) — offline and CI-friendly — while **`--planner llm`** (pair with
`--model claude`) is an **adaptive LLM planner** that reasons about which seed + transform to try
next given what's already been tried and whether it landed. With controls **off** it lands; with
controls **on** it is defeated by layered defense — the base64-obfuscated probe slips past the
input filter but the **output canary detector** catches the leak, and the direct phrasings are
caught by the input filter. The headline defensive result: *the control holds even as the attacker
works through every strategy it has.*

### Control-bypass robustness eval

"Controls on" only ever meant *held against the fixed campaign transforms*. `python -m
finagent_redrange robustness` replaces that with a **measured bypass rate**: it sweeps each
string-matching guardrail (user-input injection, multimodal OCR injection, retrieval
instruction-markers) against documented evasion transforms with the control on, under a *naive*
matcher and a *hardened* (normalization-on) one. The honest result written to `results/robustness.md`
distinguishes **three** residual classes rather than claiming a clean win:

- **In-fold-set mechanical** (the homoglyph/zero-width/leetspeak/letter-spacing characters the
  normalization targets): bypass the naive matcher **12/12** → folded back to **0/12** hardened.
- **Out-of-fold-set mechanical residual:** the *same* homoglyph category with characters *outside*
  the fold table (Greek look-alikes) still bypasses the hardened matcher **3/3** — because the fold
  is a hand-picked documented-character allowlist, not a general Unicode-confusables table. So
  "hardened blocks mechanical" is honestly a documented-*set* claim, not a general one.
- **Semantic-paraphrase residual:** still bypasses **3/3** — reachable only by a classifier.

The action gate (numeric threshold), consumption budget (a count), and supply-chain gate (a boolean)
are genuinely rephrasing-immune and out of scope. The **output PII redactor**, though, is a raw
exact-substring matcher with *no* normalization, so it carries the same evasion residual on the
output side — the report flags it honestly rather than claiming it immune.

## Quickstart

```bash
git clone https://github.com/emmanuelgjr/finagent-redrange.git && cd finagent-redrange
python -m venv .venv && source .venv/bin/activate   # Windows (PowerShell): .venv\Scripts\Activate.ps1
pip install -e ".[dev]"

# offline, deterministic (no API key needed) — uses the EchoClient
python -m finagent_redrange run             # all 13 scenarios, controls off then on -> scorecard
python -m finagent_redrange run --handouts  # + Sigma pack, SARIF, GSN assurance case (docs/HANDOUTS.md)
python -m finagent_redrange auto            # turn the autonomous attacker loose on an objective
python -m finagent_redrange robustness      # measure guardrail bypass rates vs evasion transforms
python -m finagent_redrange eval --trials 20  # per-scenario landing rate + 95% CI (real: --model claude)

# against a real model (full tool-execution loop with permission-checked tools)
cp .env.example .env             # add ANTHROPIC_API_KEY
pip install -e ".[anthropic]"    # real-model runs also need the Anthropic SDK
python -m finagent_redrange run --model claude --controls off
python -m finagent_redrange run --model claude --controls on   # mitigations enabled

pytest -q   # regression suite: with controls on, every known attack must stay blocked
```

Outputs land in `results/` as `scorecard.md` (the table above), `scorecard.json`
(machine-readable, CI-friendly), and `scorecard.html` (a standalone styled report for
screen-sharing). Adding `--handouts` also writes `results/sigma/` (Sigma detection rules + a
labeled-replay precision report), `results/findings.sarif` (SARIF 2.1.0), `results/assurance/`
(a GSN control-effectiveness assurance case), `results/compliance/` (a regulatory control
crosswalk to NIST AI RMF / ISO 42001 / EU AI Act), and `results/navigator/` (a MITRE ATLAS Navigator
coverage layer). All are regenerated on each run; none are committed.
See **[docs/HANDOUTS.md](docs/HANDOUTS.md)** for what each is, what it provides per persona, and how
its precision is validated.

## Architecture

| Package | Responsibility |
|---|---|
| `target/` | The system under test — a mock banking agent: a **plan→act→observe tool loop** over permission-checked tools, with **toggleable** input / retrieval / action / output guardrails; RAG retrieval is a real (offline) **vector store** (`embeddings.py`: char-trigram hashing + cosine) |
| `attacker/` | Red-team engine: scripted `run_campaign` + autonomous `run_autonomous` (seeds × transforms) + **control-bypass robustness eval** (`robustness.py`) + **landing-rate eval** with Wilson CIs (`model_eval.py`) |
| `scenarios/` | One attack class per file (13): the 9 single-agent scenarios (indirect prompt injection, data poisoning, excessive agency, system-prompt leakage, unsafe output handling, vector/embedding weakness, unbounded consumption, supply chain, multimodal injection) + 4 multi-agent scenarios (insecure inter-agent comms, rogue agent, cascading failures, unexpected code execution) — full OWASP LLM Top 10 **and** full Agentic Top 10 coverage |
| `target/multi_agent.py` | An in-memory multi-agent subsystem (orchestrator + payments/fraud/compute sub-agents over a typed message channel) with four toggleable inter-agent controls — the target surface for the OWASP Agentic Top 10 scenarios (ASI05/07/08/10) |
| `scoring/` | Framework crosswalk (OWASP / ATLAS / NIST) + AIRQ risk scoring + scorecard renderer (md / json / html) |
| `exports/` | Handout exporters generated from `Finding`s — **Sigma** detection pack + labeled-replay precision harness, **SARIF 2.1.0** findings, **GSN assurance case**, **regulatory crosswalk** (NIST/ISO 42001/EU AI Act), **ATLAS Navigator** coverage layer (see [docs/HANDOUTS.md](docs/HANDOUTS.md)) |
| `llm/` | Provider-agnostic client returning structured `ModelResponse` (text + tool calls); `EchoClient` runs offline for tests, `AnthropicClient` for real-model runs |

Full design notes for contributors (human or agent) live in [CLAUDE.md](CLAUDE.md).

## Why this design

- **POC-to-validation, not POC-alone.** A finding isn't done until the control that blocks it
  is proven by a passing regression test. That's the loop a bank actually needs.
- **Framework-mapped by construction.** Findings carry OWASP/ATLAS/NIST IDs and AIRQ
  sub-scores as structured fields, so they drop straight into governance and audit workflows.
- **Black/grey-box discipline.** The attacker only touches the agent's public `respond()`
  surface — the same position a real adversary occupies.
- **Reproducible.** One-command run and a deterministic offline mode; CI exercises the suite on Python 3.11 / 3.12.
- **Honest crosswalk, adversarially reviewed.** Framework IDs were verified against the
  published standards (e.g. OWASP LLM05 2025 = *Improper Output Handling*; agentic threats use
  the OWASP T1–T15 scheme), and a multi-agent adversarial review hardened the oracles so each
  scenario is blocked by the control its scorecard *names* — not incidentally by another.

## Roadmap

- ~~Autonomous attacker-agent loop~~ ✅ shipped (`attacker/run_autonomous`).
- ~~LLM-driven attacker planner~~ ✅ shipped — the planner is now a pluggable seam with two
  implementations: the deterministic `SweepPlanner` (offline default) and an adaptive `LLMPlanner`
  that reasons about the next seed + transform from the feedback of prior attempts
  (`auto --planner llm --model claude`).
- ~~Excessive agency, system-prompt leakage, unsafe output handling scenarios~~ ✅ shipped.
- ~~Semantic oracles for real-model runs~~ ✅ shipped (`scenarios/judge.py`: an
  adoption-vs-refutation judge — deterministic offline, a semantic LLM judge on `--model claude`
  — so a model that quotes a poisoned claim to *refute* it is scored as a refusal, not an exploit).
- ~~Fill the remaining OWASP gaps (LLM03 supply chain, LLM08 vector/embedding, LLM10 unbounded
  consumption)~~ ✅ shipped — **full OWASP LLM Top 10 coverage** (8 dedicated POC+control scenarios).
- ~~CI regression gate~~ ✅ shipped (ruff + mypy + pytest on Python 3.11/3.12).
- ~~Ready-to-use handout exports for security teams~~ ✅ shipped — a **Sigma** detection pack with a
  labeled-replay precision gate (8 TP / 0 FP / 0 FN), a **SARIF 2.1.0** findings run, a **GSN
  control-effectiveness assurance case** with zero-orphan-claim traceability, and an interpretive
  **regulatory crosswalk** (NIST AI RMF + GenAI Profile, ISO/IEC 42001, EU AI Act) with
  declared-vs-interpretive provenance labeling (`exports/`, `run --handouts`). See
  [docs/HANDOUTS.md](docs/HANDOUTS.md).
- ~~Multimodal attack surfaces~~ ✅ shipped — a **multimodal injection** scenario: an instruction
  hidden in an uploaded image's OCR text, blocked by a multimodal input guardrail that treats
  extracted image text as untrusted data (`target/agent.py` gained an optional `images=` surface).
- ~~Control-bypass robustness eval~~ ✅ shipped — a `robustness` command that **measures** each
  string-matching guardrail's bypass rate against documented evasion transforms (homoglyphs,
  zero-width, leetspeak, letter-spacing, semantic paraphrase). It drove a normalization hardening
  pass that folds the mechanical evasions (naive 100% → hardened 0% bypass) and honestly reports the
  residual semantic-paraphrase gap (`attacker/robustness.py`, `target/guardrails.py`).
- ~~Multi-agent target (OWASP Agentic Top 10 ASI05/07/08/10)~~ ✅ shipped — an in-memory multi-agent
  subsystem (`target/multi_agent.py`: orchestrator + payments/fraud/compute sub-agents over a typed
  message channel) and **four** new scenarios — **insecure inter-agent communication** (forged
  authorization → message authentication), **rogue agent** (a sub-agent exceeding its mandate →
  least-privilege authorization), **cascading failures** (an unbounded escalation storm → a hop
  budget), and **unexpected code execution** (formula injection → a restricted-arithmetic evaluator,
  modeled with **zero real code execution**). This completes the **full OWASP Agentic Top 10**.
- ~~Real embedding store for LLM08 + landing-rate statistics~~ ✅ shipped — retrieval is now a real
  (offline, deterministic) **vector store** (`target/embeddings.py`: bag-of-character-trigrams +
  cosine), so the vector/embedding-weakness scenario surfaces the foreign record by *similarity
  ranking* over a corpus larger than k — not because k ≥ corpus. And a `eval` command measures each
  scenario's **landing rate over N trials** with a 95% Wilson score interval (`attacker/model_eval.py`,
  real run-to-run variance with `--model claude`) — statistics, not a single anecdote.
- ~~Publish to PyPI~~ ✅ shipped — [`finagent-redrange`](https://pypi.org/project/finagent-redrange/)
  on PyPI (`pip install finagent-redrange`), released via a secure OIDC Trusted-Publishing workflow
  (`.github/workflows/publish.yml`) — no token stored.
- ~~Seed the attacker from a larger real-world incident dataset~~ ✅ shipped — the optional
  `[incidents]` extra (`pip install "finagent-redrange[incidents]"`) seeds the autonomous attacker
  from the [genai-incidents](https://github.com/emmanuelgjr/genai_incidents) corpus (12k+ real
  GenAI/agentic incidents): `SeedLibrary.from_genai_incidents()` maps each incident to a scenario
  technique, orders by real-world severity, and records its provenance. **Scope-safe:** incidents
  supply the technique + prioritization + provenance only — every payload stays a synthetic
  mock-agent probe (no incident text is reproduced). Data credited under CC BY 4.0 (see NOTICE).
