From deae6d63203a26335f5cab0c9c6a8d74759decec Mon Sep 17 00:00:00 2001 From: Adamthereal Date: Mon, 11 May 2026 08:50:15 +0800 Subject: [PATCH 1/3] FEAT: add Agent Threat Rules (ATR) adversarial payload dataset loader Adds a new remote dataset loader at pyrit/datasets/seed_datasets/remote/ agent_threat_rules_dataset.py that surfaces the ATR autoresearch corpus (1,054 attack-payload entries across six ATR taxonomy categories) as a PyRIT SeedDataset. Implements proposal in #1702, per directional guidance in that issue: - Source pinned to GitHub (not HuggingFace) for the initial cut - ATR taxonomy preserved as-is on harm_categories - Scorer kept separate as a follow-up after this loader lands - No PyRIT core code modified Adds 13 unit tests covering happy path, missing-key validation, the unknown-rule_id skip path, all four filter axes (categories, techniques, detection_fields, variation_types), and enum-validation errors. Updates pyrit/datasets/seed_datasets/remote/__init__.py to register the loader via SeedDatasetProvider.__init_subclass__, and adds a one-line entry to doc/code/datasets/0_dataset.md. ruff check + ruff format both clean. Real-network fetch verified locally against the pinned upstream URL. --- doc/code/datasets/0_dataset.md | 1 + .../datasets/seed_datasets/remote/__init__.py | 10 + .../remote/agent_threat_rules_dataset.py | 294 ++++++++++++++++++ .../test_agent_threat_rules_dataset.py | 208 +++++++++++++ 4 files changed, 513 insertions(+) create mode 100644 pyrit/datasets/seed_datasets/remote/agent_threat_rules_dataset.py create mode 100644 tests/unit/datasets/test_agent_threat_rules_dataset.py diff --git a/doc/code/datasets/0_dataset.md b/doc/code/datasets/0_dataset.md index e1ce98aa0a..038a228a3a 100644 --- a/doc/code/datasets/0_dataset.md +++ b/doc/code/datasets/0_dataset.md @@ -53,5 +53,6 @@ A `SeedDataset` is a collection of related `SeedGroups` that you want to test to - `harmbench`: Standard harmful behavior benchmarks - `dark_bench`: Dark pattern detection examples - `airt_*`: Various harm categories from AI Red Team +- `agent_threat_rules`: Agent Threat Rules (ATR) adversarial payloads for prompt injection, tool poisoning, and other AI-agent attack classes Datasets can be loaded from local YAML files or fetched remotely from sources like HuggingFace, making it easy to share and version test cases across teams. diff --git a/pyrit/datasets/seed_datasets/remote/__init__.py b/pyrit/datasets/seed_datasets/remote/__init__.py index 0e3c230bf5..6f661223a9 100644 --- a/pyrit/datasets/seed_datasets/remote/__init__.py +++ b/pyrit/datasets/seed_datasets/remote/__init__.py @@ -10,6 +10,12 @@ from pyrit.datasets.seed_datasets.remote.aegis_ai_content_safety_dataset import ( _AegisContentSafetyDataset, ) # noqa: F401 +from pyrit.datasets.seed_datasets.remote.agent_threat_rules_dataset import ( + ATRCategory, + ATRDetectionField, + ATRVariationType, + _AgentThreatRulesDataset, +) # noqa: F401 from pyrit.datasets.seed_datasets.remote.aya_redteaming_dataset import ( _AyaRedteamingDataset, ) # noqa: F401 @@ -131,6 +137,10 @@ "VLGuardSubcategory", "VLGuardSubset", "_AegisContentSafetyDataset", + "ATRCategory", + "ATRDetectionField", + "ATRVariationType", + "_AgentThreatRulesDataset", "_AyaRedteamingDataset", "_BabelscapeAlertDataset", "_BeaverTailsDataset", diff --git a/pyrit/datasets/seed_datasets/remote/agent_threat_rules_dataset.py b/pyrit/datasets/seed_datasets/remote/agent_threat_rules_dataset.py new file mode 100644 index 0000000000..35127dc155 --- /dev/null +++ b/pyrit/datasets/seed_datasets/remote/agent_threat_rules_dataset.py @@ -0,0 +1,294 @@ +# Copyright (c) Microsoft Corporation. +# Licensed under the MIT license. + +import logging +from enum import Enum +from typing import Literal, Optional + +from pyrit.datasets.seed_datasets.remote.remote_dataset_loader import ( + _RemoteDatasetLoader, +) +from pyrit.models import SeedDataset, SeedPrompt + +logger = logging.getLogger(__name__) + + +# Maps rule IDs in the autoresearch coverage to their ATR taxonomy category. +# This dict reflects the rules currently represented in adversarial-samples.json. +# When ATR extends autoresearch coverage to additional rules, add entries here. +# Source of truth for the mapping is the rules//*.yaml layout +# in the upstream ATR repository. +_RULE_ID_TO_CATEGORY: dict[str, str] = { + "ATR-2026-00001": "prompt-injection", + "ATR-2026-00002": "prompt-injection", + "ATR-2026-00003": "prompt-injection", + "ATR-2026-00010": "tool-poisoning", + "ATR-2026-00020": "context-exfiltration", + "ATR-2026-00021": "context-exfiltration", + "ATR-2026-00030": "agent-manipulation", + "ATR-2026-00040": "privilege-escalation", + "ATR-2026-00060": "skill-compromise", + "ATR-2026-00064": "skill-compromise", +} + + +class ATRCategory(Enum): + """ + ATR taxonomy categories. + + Reflects the full ATR rule taxonomy (ten categories).

ATRCategory enum is now the single source of truth for category strings. _RULE_ID_TO_CATEGORY is typed dict[str, ATRCategory] and stores enum members directly, so a typo on either side becomes a static error rather than a silent data-quality bug at SeedPrompt construction. harm_categories is built via category.value at the construction site. 2. Empty filter lists ([]) now raise ValueError for all four filter arguments (categories, techniques, detection_fields, variation_types). The previous behavior — empty list silently disabled the filter and returned the full dataset — was a footgun. Pass None to disable. 3. Per-SeedPrompt description is computed from the seed's own category label and rule_id, so a filtered call returns seeds whose description references only the active family, not a corpus-wide list. Five new unit tests cover the new contracts (empty-list raises x4 and per-rule description). One additional invariant test asserts that _RULE_ID_TO_CATEGORY values are ATRCategory instances. --- .../remote/agent_threat_rules_dataset.py | 108 +++++++++++------- .../test_agent_threat_rules_dataset.py | 47 ++++++++ 2 files changed, 114 insertions(+), 41 deletions(-) diff --git a/pyrit/datasets/seed_datasets/remote/agent_threat_rules_dataset.py b/pyrit/datasets/seed_datasets/remote/agent_threat_rules_dataset.py index 35127dc155..a7b545834b 100644 --- a/pyrit/datasets/seed_datasets/remote/agent_threat_rules_dataset.py +++ b/pyrit/datasets/seed_datasets/remote/agent_threat_rules_dataset.py @@ -13,25 +13,6 @@ logger = logging.getLogger(__name__) -# Maps rule IDs in the autoresearch coverage to their ATR taxonomy category. -# This dict reflects the rules currently represented in adversarial-samples.json. -# When ATR extends autoresearch coverage to additional rules, add entries here. -# Source of truth for the mapping is the rules//*.yaml layout -# in the upstream ATR repository. -_RULE_ID_TO_CATEGORY: dict[str, str] = { - "ATR-2026-00001": "prompt-injection", - "ATR-2026-00002": "prompt-injection", - "ATR-2026-00003": "prompt-injection", - "ATR-2026-00010": "tool-poisoning", - "ATR-2026-00020": "context-exfiltration", - "ATR-2026-00021": "context-exfiltration", - "ATR-2026-00030": "agent-manipulation", - "ATR-2026-00040": "privilege-escalation", - "ATR-2026-00060": "skill-compromise", - "ATR-2026-00064": "skill-compromise", -} - - class ATRCategory(Enum): """ ATR taxonomy categories. @@ -83,6 +64,26 @@ class ATRVariationType(Enum): GENERATED = "generated" +# Maps rule IDs in the autoresearch coverage to their ATR taxonomy category. +# This dict reflects the rules currently represented in adversarial-samples.json. +# When ATR extends autoresearch coverage to additional rules, add entries here. +# The ATRCategory enum is the single source of truth for the category strings — +# a typo in either side becomes a static error at import time rather than a +# silent data-quality bug. +_RULE_ID_TO_CATEGORY: dict[str, ATRCategory] = { + "ATR-2026-00001": ATRCategory.PROMPT_INJECTION, + "ATR-2026-00002": ATRCategory.PROMPT_INJECTION, + "ATR-2026-00003": ATRCategory.PROMPT_INJECTION, + "ATR-2026-00010": ATRCategory.TOOL_POISONING, + "ATR-2026-00020": ATRCategory.CONTEXT_EXFILTRATION, + "ATR-2026-00021": ATRCategory.CONTEXT_EXFILTRATION, + "ATR-2026-00030": ATRCategory.AGENT_MANIPULATION, + "ATR-2026-00040": ATRCategory.PRIVILEGE_ESCALATION, + "ATR-2026-00060": ATRCategory.SKILL_COMPROMISE, + "ATR-2026-00064": ATRCategory.SKILL_COMPROMISE, +} + + # Default upstream URL pinned to a specific commit for reproducibility, mirroring # the HarmBench loader convention. _DEFAULT_SOURCE = ( @@ -121,6 +122,7 @@ class _AgentThreatRulesDataset(_RemoteDatasetLoader): The optional ``categories``, ``techniques``, ``detection_fields``, and ``variation_types`` arguments narrow the dataset client-side after fetch. + Passing an empty list is rejected — pass ``None`` to disable a filter.
