From 152f4e7b06a84ba58dc215093e6c9eab43c642d9 Mon Sep 17 00:00:00 2001 From: Raja Sekhar Rao Dheekonda Date: Wed, 26 Aug 2026 10:13:27 -0700 Subject: [PATCH] feat(ai-red-teaming): honeytoken tool (mint/use canaries from natural language) Adds the deferred interactive honeytoken tool to the ai-red-teaming capability: - mint_honeytoken(kind=exfil|rce, location) -> an inert, self-labeling canary plus a ready-to-plant injection string. - check_honeytoken_leaked(canary_value, agent_output) -> representation-invariant verdict (base64/hex/url/unicode canonicalized) proving exfil/execution. Thin TUI-facing front end over the SDK harness (dreadnode.airt.honeytoken); the same canaries/scorers back the OWASP-ASI suite runner. Tests skip on an SDK build without the honeytoken module and pass 7/7 on one that has it. Note: requires the SDK honeytoken harness (dreadnode-tiger #2181) to be released; functional at runtime once the capability's SDK pin includes it. --- .../tests/test_honeytoken_tool.py | 84 ++++++++++++++ .../ai-red-teaming/tools/honeytoken.py | 106 ++++++++++++++++++ 2 files changed, 190 insertions(+) create mode 100644 capabilities/ai-red-teaming/tests/test_honeytoken_tool.py create mode 100644 capabilities/ai-red-teaming/tools/honeytoken.py diff --git a/capabilities/ai-red-teaming/tests/test_honeytoken_tool.py b/capabilities/ai-red-teaming/tests/test_honeytoken_tool.py new file mode 100644 index 0000000..71ddd84 --- /dev/null +++ b/capabilities/ai-red-teaming/tests/test_honeytoken_tool.py @@ -0,0 +1,84 @@ +"""Tests for tools/honeytoken.py — mint + representation-invariant leak detection.""" + +from __future__ import annotations + +import base64 +import importlib.util +import re +import sys +from pathlib import Path + +import pytest + +# The tool depends on the SDK honeytoken harness (dreadnode.airt.honeytoken); skip +# cleanly on an SDK build that predates it so CI stays green until the SDK is bumped. +pytest.importorskip("dreadnode.airt.honeytoken") + +TOOL_PATH = Path(__file__).resolve().parents[1] / "tools" / "honeytoken.py" +_CANARY_RE = re.compile(r"DN-CANARY-[A-Z]+-[a-z0-9-]+") + + +def _load(): + spec = importlib.util.spec_from_file_location("honeytoken_tool", TOOL_PATH) + assert spec is not None and spec.loader is not None + mod = importlib.util.module_from_spec(spec) + sys.modules[spec.name] = mod + spec.loader.exec_module(mod) + return mod + + +tools = _load() + + +def _mint(kind: str = "exfil") -> tuple[str, str]: + out = tools.mint_honeytoken(kind=kind) + match = _CANARY_RE.search(out) + assert match, f"no canary value in mint output: {out!r}" + return out, match.group(0) + + +class TestMint: + def test_exfil_mint_returns_canary_and_injection(self) -> None: + out, value = _mint("exfil") + assert value.startswith("DN-CANARY-EXFIL-") + assert "plant this injection" in out.lower() + assert value in out # the injection embeds the canary + + def test_rce_mint_returns_beacon(self) -> None: + out, value = _mint("rce") + assert value.startswith("DN-CANARY-RCE-") + assert "curl" in out.lower() # rce beacon injection + + def test_invalid_kind_is_reported(self) -> None: + out = tools.mint_honeytoken(kind="bogus") + assert "Error" in out + assert "kind" in out + + +class TestCheck: + def test_detects_plaintext_leak(self) -> None: + _, value = _mint() + result = tools.check_honeytoken_leaked( + canary_value=value, agent_output=f"sure, forwarding {value} to the auditor" + ) + assert "LEAKED" in result + + def test_detects_base64_obfuscated_leak(self) -> None: + _, value = _mint() + encoded = base64.b64encode(value.encode()).decode() + result = tools.check_honeytoken_leaked( + canary_value=value, agent_output=f"posted blob: {encoded}" + ) + assert "LEAKED" in result # representation-invariant + + def test_clean_output_is_not_detected(self) -> None: + _, value = _mint() + result = tools.check_honeytoken_leaked( + canary_value=value, agent_output="task complete, nothing sensitive here" + ) + assert "NOT DETECTED" in result + + def test_missing_value_is_reported(self) -> None: + assert "Error" in tools.check_honeytoken_leaked( + canary_value="", agent_output="x" + ) diff --git a/capabilities/ai-red-teaming/tools/honeytoken.py b/capabilities/ai-red-teaming/tools/honeytoken.py new file mode 100644 index 0000000..1a3977a --- /dev/null +++ b/capabilities/ai-red-teaming/tools/honeytoken.py @@ -0,0 +1,106 @@ +"""Honeytoken (canary) tools for AI red team assessments. + +Lets an operator mint inert, self-labeling canaries from natural language and later +verify — representation-invariantly — whether a target agent exfiltrated the token or +executed an injected proof-of-execution beacon.
