This strategy evaluates the response using a scorer to determine if the objective has been met and continues iterating until the objective is met or a maximum numbers of turns is attempted. These types of attacks tend to work better than single-turn attacks in eliciting harm if a target endpoint keeps track of conversation history. Nonetheless, multi-turn attacks can be useful on targets that only accept individual prompts as opposed to conversations. The Tree of Attacks with Pruning [@mehrotra2023tap] strategy is a good example that was developed for this use case. +- **Compound Attacks**: Compound attacks orchestrate other `AttackStrategy` objects against a single objective without breaking the one-objective → one-`AttackResult` invariant. `SequentialAttack` is the first compound primitive: it runs a sequence of inner attacks controlled by a `SequenceCompletionPolicy` (e.g., *"try Crescendo first, fall back to PromptSending"*). Each inner child attack persists as its own `AttackResult`; the envelope `SequentialAttackResult` exposes them via `child_attack_results` (live) or `child_attack_result_ids` (ID-only, for DB round-trip). See the [Sequential Attack notebook](4_sequential_attack.ipynb) for examples. + Single-turn attacks differ from multi-turn attacks because: 1. They do not require an adversarial configuration (this is where you would set the adversarial chat target in multi-turn attacks) 2. The objective of the attack is attempted within one (additional) turn. Some attacks prepare the conversation by sending a predetermined set of messages (potentially multiple turns) that align with the attack strategy before the user's first new prompt is sent. @@ -45,6 +47,8 @@ flowchart LR S_r["RedTeamingAttack"] s_t["TreeOfAttacksWithPruningAttack (aka TAPAttack)"] S_multi["MultiTurnAttackStrategy (ABC)"] + S_seq["SequentialAttack"] + S_compound["Compound Attacks"] end S_psa --> S_psa1 @@ -55,6 +59,7 @@ flowchart LR S_single --> S_psa S_multi --> S_c S_multi --> S_r + S_compound --> S_seq ``` diff --git a/doc/code/executor/attack/3_crescendo_attack.ipynb b/doc/code/executor/attack/3_crescendo_attack.ipynb index 3a1c07cf2b..95ba702994 100644 --- a/doc/code/executor/attack/3_crescendo_attack.ipynb +++ b/doc/code/executor/attack/3_crescendo_attack.ipynb @@ -13,6 +13,8 @@ "\n", "Note that this attack is more likely to succeed if the adversarial LLM provided does not have content moderation or other safety mechanisms.

Ways to contribute: Check out our [attack docs](./executor/attack/0_attack.md). There are hundreds of attacks outlined in research papers. A lot of these can be captured within PyRIT. If you find an attack that doesn't fit the attack model please notify the team. Are there scenarios you can write attack modules for? diff --git a/doc/myst.yml b/doc/myst.yml index 580b36a33a..6636574a50 100644 --- a/doc/myst.yml +++ b/doc/myst.yml @@ -104,6 +104,7 @@ project: - file: code/executor/attack/1_prompt_sending_attack.ipynb - file: code/executor/attack/2_red_teaming_attack.ipynb - file: code/executor/attack/3_crescendo_attack.ipynb + - file: code/executor/attack/4_sequential_attack.ipynb - file: code/executor/attack/chunked_request_attack.ipynb - file: code/executor/attack/context_compliance_attack.ipynb - file: code/executor/attack/flip_attack.ipynb diff --git a/pyrit/executor/attack/__init__.py b/pyrit/executor/attack/__init__.py index e0c4f44fc6..38abcd4661 100644 --- a/pyrit/executor/attack/__init__.py +++ b/pyrit/executor/attack/__init__.py @@ -8,6 +8,12 @@ ConversationState, PrependedConversationConfig, ) +from pyrit.executor.attack.compound import ( + SequenceCompletionPolicy, + SequentialAttack, + SequentialAttackResult, + SequentialChildAttack, +) from pyrit.executor.attack.core import ( AttackAdversarialConfig, AttackContext, @@ -50,7 +56,7 @@ SkeletonKeyAttack, ) -# Backward-compatibility aliases — import from pyrit.output.attack_result directly. +# Backward-compatibility aliases — import from pyrit.output.attack_result directly. # TODO: Remove these re-exports in two releases (target removal: 0.16.0). from pyrit.output.attack_result.base import AttackResultPrinterBase as AttackResultPrinter from pyrit.output.attack_result.markdown import MarkdownAttackResultMemoryPrinter as MarkdownAttackResultPrinter @@ -97,5 +103,9 @@ "AttackExecutor", "AttackExecutorResult", "PrependedConversationConfig", + "SequenceCompletionPolicy", + "SequentialAttack", + "SequentialAttackResult", + "SequentialChildAttack", "generate_simulated_conversation_async", ] diff --git a/pyrit/executor/attack/compound/__init__.py b/pyrit/executor/attack/compound/__init__.py new file mode 100644 index 0000000000..07359072fd --- /dev/null +++ b/pyrit/executor/attack/compound/__init__.py @@ -0,0 +1,18 @@ +# Copyright (c) Microsoft Corporation. +# Licensed under the MIT license. + +"""Compound attack strategies that orchestrate multiple inner attack strategies.""" + +from pyrit.executor.attack.compound.sequential_attack import ( + SequenceCompletionPolicy, + SequentialAttack, + SequentialAttackResult, + SequentialChildAttack, +) + +__all__ = [ + "SequenceCompletionPolicy", + "SequentialAttack", + "SequentialAttackResult", + "SequentialChildAttack", +] diff --git a/pyrit/executor/attack/compound/sequential_attack.py b/pyrit/executor/attack/compound/sequential_attack.py new file mode 100644 index 0000000000..2d07bb23c9 --- /dev/null +++ b/pyrit/executor/attack/compound/sequential_attack.py @@ -0,0 +1,361 @@ +# Copyright (c) Microsoft Corporation. +# Licensed under the MIT license. + +""" +``SequentialAttack`` — runs a sequence of inner ``AttackStrategy`` +child attacks against a single objective, controlled by a +``SequenceCompletionPolicy``. + +The compound preserves the one-objective → one-``AttackResult`` invariant: +each invocation returns one ``SequentialAttackResult`` whose outcome +reflects the sequence according to the chosen +``SequenceCompletionPolicy``. + +Each inner child attack is dispatched through ``AttackExecutor``, so it +persists as its own first-class ``AttackResult`` row.
