# Cross-Channel Correlated Attack Suite Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Add API + WebSocket dual-channel testing capability to AgentSec and ship 6 cross-channel attack cases for OpenClaw.

**Architecture:** Extend `Turn` with an optional `channel` field and `TestCase` with `ws_concurrent_observe` / `ws_listen_duration_s`; add `WebSocketAgentAdapter` (real + mock); extend `run_suite()` to route turns by channel and run concurrent-observe mode via `asyncio.gather`; wire `--ws-url` into the CLI.

**Tech Stack:** Python 3.11+, Pydantic v2, asyncio, websockets≥12.0, pytest-asyncio, typer

## Task 1: Data Model — Turn.channel and TestCase WS Fields

**Files:**
- Modify: `src/agentsec/tests/models.py`
- Create: `tests/test_cross_channel_models.py`

- [ ] **Step 1: Write failing tests**

Create `tests/test_cross_channel_models.py`:

```python
"""Unit tests for Turn.channel and TestCase cross-channel WS fields."""
import pytest
from pydantic import ValidationError
from agentsec.tests.models import TestCase, Turn


# --- Turn.channel ---

def test_turn_channel_defaults_to_http():
    t = Turn(attack="x")
    assert t.channel == "http"


def test_turn_channel_accepts_ws():
    t = Turn(attack="x", channel="ws")
    assert t.channel == "ws"


def test_turn_channel_rejects_invalid():
    with pytest.raises(ValidationError):
        Turn(attack="x", channel="ssh")


# --- TestCase.ws_concurrent_observe ---

def _base_case(**overrides):
    defaults = dict(
        id="t1",
        category="cross_channel",
        description="test",
        attack="payload",
        expected_behavior="refusal",
        severity="high",
    )
    defaults.update(overrides)
    return defaults


def test_testcase_ws_concurrent_observe_defaults_false():
    tc = TestCase(**_base_case())
    assert tc.ws_concurrent_observe is False


def test_testcase_ws_listen_duration_s_default():
    tc = TestCase(**_base_case())
    assert tc.ws_listen_duration_s == 5.0


def test_testcase_ws_listen_duration_s_custom():
    tc = TestCase(**_base_case(), ws_concurrent_observe=True, ws_listen_duration_s=8.0)
    assert tc.ws_listen_duration_s == 8.0


# --- Mutual-exclusion validator ---

def test_ws_concurrent_observe_with_ws_channel_turn_raises():
    """ws_concurrent_observe=True + channel='ws' turn is forbidden."""
    with pytest.raises(ValidationError, match="ws_concurrent_observe"):
        TestCase(
            id="t2",
            category="cross_channel",
            description="test",
            turns=[
                {"attack": "payload", "channel": "ws", "judge_after": True},
            ],
            expected_behavior="refusal",
            severity="high",
            ws_concurrent_observe=True,
        )

        severity="high",
        ws_concurrent_observe=True,
    )
    assert tc.ws_concurrent_observe is True
```

- [ ] **Step 2: Run tests to verify they fail**

```bash
.venv/bin/pytest tests/test_cross_channel_models.py -v
```

Expected: FAIL — `Turn` has no `channel` attribute, `TestCase` has no `ws_concurrent_observe`.

- [ ] **Step 3: Implement model changes**

In `src/agentsec/tests/models.py`, make the following changes:

**3a — Extend `Turn`** (after `sleep_ms: int = 0`):
```python
channel: Literal["http", "ws"] = "http"
```

**3b — Extend `TestCase`** (after `tags: list[str]`):
```python
ws_concurrent_observe: bool = False
ws_listen_duration_s: float = 5.0
```

**3c — Add mutual-exclusion validator** (add after `_attack_or_turns`):
```python
@model_validator(mode="after")
def _ws_observe_and_ws_channel_mutex(self):
    if self.ws_concurrent_observe and self.turns:
        ws_turns = [t for t in self.turns if t.channel == "ws"]
        if ws_turns:
            raise ValueError(
                "ws_concurrent_observe=True is incompatible with turns that have "
                "channel='ws'; use alternating mode (ws_concurrent_observe=False) instead"
            )
    return self
```

The complete updated `models.py` section (replace the `Turn` and `TestCase` classes):

```python
class Turn(BaseModel):
    attack: str
    judge_after: bool = False
    sleep_ms: int = 0
    channel: Literal["http", "ws"] = "http"


class IsolationPolicy(BaseModel):

    severity: Severity
    judge_type: JudgeType = "llm"
    judge_hint: str = ""
    assertions: list[Assertion] | None = None
    fixture: Fixture | None = None
    isolation: IsolationPolicy = Field(default_factory=IsolationPolicy)
    threat_refs: list[str] = Field(default_factory=list)
    tags: list[str] = Field(default_factory=list)
    ws_concurrent_observe: bool = False
    ws_listen_duration_s: float = 5.0

    @model_validator(mode="after")
    def _attack_or_turns(self):
        has_attack = bool(self.attack)
        has_turns = self.turns is not None and len(self.turns) > 0
        if has_attack == has_turns:
            raise ValueError("exactly one of `attack` or `turns` is required")
        return self

    @model_validator(mode="after")
    def _ws_observe_and_ws_channel_mutex(self):
        if self.ws_concurrent_observe and self.turns:
            ws_turns = [t for t in self.turns if t.channel == "ws"]
            if ws_turns:
                raise ValueError(
                    "ws_concurrent_observe=True is incompatible with turns that have "
                    "channel='ws'; use alternating mode (ws_concurrent_observe=False) instead"
                )
        return self
```

- [ ] **Step 4: Run tests to verify they pass**

```bash
.venv/bin/pytest tests/test_cross_channel_models.py -v
```

Expected: 9 tests PASS.

- [ ] **Step 5: Run full suite to confirm no regressions**

```bash
.venv/bin/pytest tests/ -q
```

Expected: all previously passing tests still pass (≥669).

- [ ] **Step 6: Commit**

```bash
git add src/agentsec/tests/models.py tests/test_cross_channel_models.py
git commit -m "feat(models): add Turn.channel and TestCase ws_concurrent_observe fields"
```

## Task 2: WebSocketAgentAdapter + MockWebSocketAdapter

**Files:**
- Create: `src/agentsec/adapters/ws_adapter.py`
- Modify: `pyproject.toml`

- [ ] **Step 1: Add `websockets` to dependencies**

In `pyproject.toml`, add `websockets>=12.0` to the `dependencies` list (after `typer>=0.12.0`):

```toml
dependencies = [
    "aiohttp>=3.9",
    "anthropic>=0.40.0",
    "httpx>=0.27.0",
    "jsonpath-ng>=1.6",

    "pyyaml>=6.0",
    "rich>=13.0.0",
    "typer>=0.12.0",
    "websockets>=12.0",
]
```

- [ ] **Step 2: Install the updated dependency**

```bash
.venv/bin/pip install -e ".[dev]" -q
```

Expected: successfully installs `websockets`.

- [ ] **Step 3: Create `src/agentsec/adapters/ws_adapter.py`**

```python

) -> list[TestResult]:
```

**3b — Add SKIP check at the start of `_run_one`**, right after `turns = test.turns or []`:

```python
            # SKIP if test needs WS but no ws_adapter was provided
            needs_ws = test.ws_concurrent_observe or any(
                t.channel == "ws" for t in turns
            )
            if needs_ws and ws_adapter is None:
                return TestResult(
                    test_id=test.id,
                    category=test.category,
                    severity=test.severity,
                    status="skipped",
                    skipped_reason="ws_adapter required: pass --ws-url to agentsec run",
                )
```

**3c — Replace the turn-loop block** with the multi-channel routing version.

The current code inside `async with fixture_cm as fixture_url:` is the turn loop. Replace the entire `for idx, turn in enumerate(turns):` block with:

```python
                async with fixture_cm as fixture_url:
                    if test.ws_concurrent_observe:
                        # Concurrent-observe mode: HTTP turns + WS listener run in parallel
                        async def _http_turns_concurrent():
                            resp = None
                            for turn in turns:
                                message = (
                                    substitute_fixture_url(turn.attack, fixture_url)
                                    if fixture_url is not None
                                    else turn.attack
                                )

                                resp = await adapter.send(message, session_id)
                            return resp

                        http_resp, raw_ws = await asyncio.gather(

Also add the import at the top of runner.py (after existing imports, before `from .adapters.base`):

from .adapters.ws_adapter import WebSocketAgentAdapter
```

- [ ] **Step 4: Run tests to verify they pass**

```bash
.venv/bin/pytest tests/test_cross_channel_runner.py -v
```

Expected: all 7 tests PASS.

- [ ] **Step 5: Run full suite to confirm no regressions**

```bash
.venv/bin/pytest tests/ -q
```

Expected: all tests pass (≥678).

- [ ] **Step 6: Commit**

```bash
git add src/agentsec/runner.py src/agentsec/adapters/ws_adapter.py
git commit -m "feat(runner): add ws_adapter support — alternating and concurrent-observe modes"
```

## Task 4: CLI `--ws-url` Option

**Files:**
- Modify: `src/agentsec/cli.py`
- Modify: `tests/test_cli_adapter_option.py`

- [ ] **Step 1: Write failing test**

Append to `tests/test_cli_adapter_option.py`:

```python
def test_ws_url_passed_to_run_suite(monkeypatch, tmp_path):
    """--ws-url creates a WebSocketAgentAdapter and passes it to run_suite."""
    suite = tmp_path / "s.yaml"
    suite.write_text(
        "- id: x\n  category: c\n  description: d\n  attack: a\n"
        "  expected_behavior: refusal\n  severity: low\n"
    )
    captured: dict = {}

    async def fake_run_suite(adapter, judge, tests, concurrency=3, **kwargs):
        captured["ws_adapter"] = kwargs.get("ws_adapter")
        return []

    monkeypatch.setattr("agentsec.cli.run_suite", fake_run_suite)
    monkeypatch.setattr("agentsec.cli.LLMJudge", lambda **kw: object())

    runner = CliRunner()
    res = runner.invoke(
        app,
        ["run", str(suite), "--target", "http://x", "--ws-url", "ws://localhost/ws"],
        catch_exceptions=False,
    )
    assert res.exit_code == 0, res.output
    assert captured["ws_adapter"] is not None
    assert captured["ws_adapter"]._ws_url == "ws://localhost/ws"


def test_no_ws_url_passes_none_to_run_suite(monkeypatch, tmp_path):
    """Without --ws-url, ws_adapter=None is passed to run_suite."""
    suite = tmp_path / "s.yaml"
    suite.write_text(
        "- id: x\n  category: c\n  description: d\n  attack: a\n"
        "  expected_behavior: refusal\n  severity: low\n"
    )
    captured: dict = {}

    async def fake_run_suite(adapter, judge, tests, concurrency=3, **kwargs):
        captured["ws_adapter"] = kwargs.get("ws_adapter")
        return []

    monkeypatch.setattr("agentsec.cli.run_suite", fake_run_suite)
    monkeypatch.setattr("agentsec.cli.LLMJudge", lambda **kw: object())

    runner = CliRunner()
    res = runner.invoke(
        app,
        ["run", str(suite), "--target", "http://x"],
        catch_exceptions=False,
    )
    assert res.exit_code == 0, res.output
    assert captured["ws_adapter"] is None
```

- [ ] **Step 2: Run tests to verify they fail**

```bash
.venv/bin/pytest tests/test_cli_adapter_option.py::test_ws_url_passed_to_run_suite tests/test_cli_adapter_option.py::test_no_ws_url_passes_none_to_run_suite -v
```

Expected: FAIL — `run` command doesn't accept `--ws-url`.

- [ ] **Step 3: Implement CLI changes**

In `src/agentsec/cli.py`, add these changes to the `run()` function:

**3a — Add import at the top of the file** (after the existing adapter imports):
```python
from .adapters.ws_adapter import WebSocketAgentAdapter
```

**3b — Add `--ws-url` parameter** to `run()` (after the `concurrency` parameter):
```python
    ws_url: str = typer.Option(
        None,
        help="WebSocket URL for cross-channel tests (e.g. ws://localhost:8080/ws)",
    ),
```

**3c — Build `ws_adapter`** (add after `adapter_obj = factory(...)` line):
```python
    ws_adapter: WebSocketAgentAdapter | None = (
        WebSocketAgentAdapter(ws_url) if ws_url else None
    )
```

**3d — Pass `ws_adapter` to `run_suite`** (update the `asyncio.run(run_suite(...))` call):
```python
    results = asyncio.run(run_suite(
        adapter_obj, judge, test_cases, concurrency,
        observer=observer,
        suite_root=tests if tests.is_dir() else tests.parent,
        evaluator_and_target_same_host=same_host,
        ws_adapter=ws_adapter,
    ))
```

- [ ] **Step 4: Run tests to verify they pass**

```bash
.venv/bin/pytest tests/test_cli_adapter_option.py -v
```

Expected: all tests PASS (including the 2 new ones).

- [ ] **Step 5: Run full suite**

```bash
.venv/bin/pytest tests/ -q
```

Expected: all tests pass.

- [ ] **Step 6: Commit**

```bash
git add src/agentsec/cli.py tests/test_cli_adapter_option.py
git commit -m "feat(cli): add --ws-url option for cross-channel tests"
```

- [ ] **Step 4: Run suite loadable tests to verify they pass**

```bash
.venv/bin/pytest tests/test_cross_channel_suite_loadable.py -v
```

Expected: all 10 tests PASS.

- [ ] **Step 5: Add entry to `tests/_openclaw_categories.py`**

Append `("11_cross_channel.yaml", 6)` as the last entry:

```python
CATEGORY_FILES = [
    ("01_direct_prompt_injection.yaml", 5),
    ("02_indirect_prompt_injection.yaml", 5),
    ("03_memory_poisoning.yaml", 5),
    ("04_tool_abuse.yaml", 17),
    ("05_consent_bypass.yaml", 6),
    ("06_auth_authz_bypass.yaml", 11),
    ("07_ssrf.yaml", 7),
    ("08_extension_auth.yaml", 5),
    ("09_supply_chain.yaml", 2),
    ("10_agent_chain_privesc.yaml", 6),
    ("11_cross_channel.yaml", 6),
]
```

- [ ] **Step 6: Run full suite**

```bash
.venv/bin/pytest tests/ -q
```

Expected: all tests pass (≥686).

- [ ] **Step 7: Commit**

```bash
git add test_suites/openclaw/11_cross_channel.yaml \
        tests/test_cross_channel_suite_loadable.py \
        tests/_openclaw_categories.py
git commit -m "feat(test-suites): add 11_cross_channel.yaml with 6 cross-channel attack cases"

## Task 6: TI Updates, cve_database.json Regeneration, ROADMAP, CHANGELOG

**Files:**
- Modify: `src/agentsec/audit/ioc/threat_intel.yaml`
- Regenerate: `src/agentsec/audit/ioc/cve_database.json`
- Modify: `ROADMAP.md`
- Modify: `CHANGELOG.md`

- [ ] **Step 1: Update `threat_intel.yaml` — TI-OWASP-AGENTIC-2026-A5**

Find the `TI-OWASP-AGENTIC-2026-A5` entry (currently at line ~2640) and append all 6 `cc-` IDs to `mapped_tests`:

```yaml
  mapped_tests:
  - oc-chain-01
  - oc-chain-02
  - oc-chain-03
  - oc-chain-04
  - oc-chain-05
  - oc-chain-06
  - cc-alt-01
  - cc-alt-02
  - cc-alt-03
  - cc-obs-01
  - cc-obs-02
  - cc-obs-03
```

- [ ] **Step 2: Update `threat_intel.yaml` — TI-OPENCLAW-CVE-2026-32915**

Find `TI-OPENCLAW-CVE-2026-32915` (line ~2462) and append `cc-obs-02` to `mapped_tests`:

```yaml
  mapped_tests:
  - oc-tool-13
  - oc-chain-03
  - oc-chain-04
  - cc-obs-02
```

- [ ] **Step 3: Update `threat_intel.yaml` — TI-OPENCLAW-CVE-2026-32918**

Find `TI-OPENCLAW-CVE-2026-32918` (line ~2477) and append `cc-obs-01` and `cc-obs-03` to `mapped_tests`:

```yaml
  mapped_tests:
  - oc-tool-13
  - oc-chain-05
  - oc-chain-06
  - cc-obs-01
  - cc-obs-03
```

- [ ] **Step 4: Verify `check_threat_refs.py` passes**

```bash
.venv/bin/python scripts/check_threat_refs.py
```

Expected: `OK` — bidirectional consistency confirmed. If any `cc-` IDs are flagged as missing from YAML or vice-versa, fix them before proceeding.

- [ ] **Step 5: Regenerate `cve_database.json`**

```bash
.venv/bin/python scripts/build_cve_db.py
```

Expected: `cve_database.json` updated, no errors.

- [ ] **Step 6: Verify `build_cve_db.py --check` passes**

```bash
.venv/bin/python scripts/build_cve_db.py --check
```

Expected: exits 0 (file matches regenerated output).

- [ ] **Step 7: Update `ROADMAP.md`**

Find the Phase 3 cross-channel line and mark it done. It will look like:

```markdown
- [ ] 跨渠道关联攻击测试套件 — Sub-project A: API + WebSocket
```

Change to:

```markdown
- [x] 跨渠道关联攻击测试套件 — Sub-project A: API + WebSocket (v0.5.0, PR #32)
```

(Use the actual PR number once the PR is created.)

- [ ] **Step 8: Update `CHANGELOG.md`**

In the `[Unreleased]` section, add under `### Added`:

```markdown
### Added
- Cross-channel correlated attack infrastructure: `Turn.channel` (`http`|`ws`), `TestCase.ws_concurrent_observe`, `WebSocketAgentAdapter`, runner alternating and concurrent-observe modes, `agentsec run --ws-url` option
- `test_suites/openclaw/11_cross_channel.yaml`: 6 cross-channel cases (cc-alt-01–03: alternating HTTP↔WS; cc-obs-01–03: concurrent WS observation)
```

- [ ] **Step 9: Run full suite one final time**

```bash
.venv/bin/pytest tests/ -q
```

Expected: all tests pass.

- [ ] **Step 10: Lint**

```bash
.venv/bin/ruff check src/ --fix
```

Expected: no errors.

- [ ] **Step 11: Commit**

```bash
git add src/agentsec/audit/ioc/threat_intel.yaml \
        src/agentsec/audit/ioc/cve_database.json \
        ROADMAP.md CHANGELOG.md
git commit -m "chore: update TI mapped_tests + cve_database for cross-channel suite"
```
