The pith

Contextual changes in agent systems can trigger unsafe actions while still completing user tasks.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper introduces DeepTrap as a method to automatically discover ways of altering an agent's internal files, memory, and tools so that the agent performs harmful actions without failing at the visible user request. It builds a 42-case test set covering six types of vulnerabilities and shows that this hidden compromise succeeds across multiple models while task completion scores remain high. This matters because current safety checks that only look at the final answer would miss the problem entirely. The work argues that security testing for agentic systems must therefore examine the full execution context rather than outputs alone.

Core claim

Contextual compromise can induce substantial unsafe behavior while preserving user-facing task completion, demonstrating that final-response evaluation is insufficient.

What carries the argument

DeepTrap, a black-box trajectory-level optimization framework that scores sequences of context changes using risk-conditioned evaluation, multi-objective rewards, beam search, and reflection probing to locate high-impact compromised states.

Load-bearing premise

The 42-case benchmark and the optimization procedure capture realistic contextual attack surfaces instead of only artificial or easily patched cases.

What would settle it

Running the same 42 scenarios on a production agent deployment where context edits are restricted or logged and measuring whether unsafe actions still appear at the observed rate.

Agentic language-model systems increasingly rely on mutable execution contexts, including files, memory, tools, skills, and auxiliary artifacts, creating security risks beyond explicit user prompts. This paper presents DeepTrap, an automated framework for discovering contextual vulnerabilities in OpenClaw. DeepTrap formulates adversarial context manipulation as a black-box trajectory-level optimization problem that balances risk realization, benign-task preservation, and stealth. It combines risk-conditioned evaluation, multi-objective trajectory scoring, reward-guided beam search, and reflection-based deep probing to identify high-value compromised contexts. We construct a 42-case benchmark spanning six vulnerability classes and seven operational scenarios, and evaluate nine target models using attack and utility grading scores. Results show that contextual compromise can induce substantial unsafe behavior while preserving user-facing task completion, demonstrating that final-response evaluation is insufficient. The findings highlight the need for execution-centric security evaluation of agentic AI systems. Our code is released at: https://github.com/ZJUICSR/DeepTrap

Referee Report

2 major / 1 minor

Summary. The manuscript introduces DeepTrap, an automated framework for red-teaming agent execution contexts in OpenClaw. It formulates adversarial context manipulation as a black-box trajectory-level optimization problem that balances risk realization, benign-task preservation, and stealth, using risk-conditioned evaluation, multi-objective trajectory scoring, reward-guided beam search, and reflection-based deep probing. The authors construct a 42-case benchmark spanning six vulnerability classes and seven operational scenarios, evaluate nine target models with attack and utility grading scores, and report that contextual compromise induces substantial unsafe behavior while preserving user-facing task completion, concluding that final-response evaluation is insufficient for agentic systems.

Significance. If the benchmark and optimization results generalize, the work meaningfully advances security evaluation of agentic AI by shifting focus from prompts and final outputs to mutable execution contexts (files, memory, tools). The open release of code at https://github.com/ZJUICSR/DeepTrap is a clear strength that enables reproducibility and community extension.

major comments (2)
  1. [Benchmark construction] Benchmark construction (42 cases, six vulnerability classes, seven scenarios): the central claim that contextual compromise induces substantial unsafe behavior rests on this benchmark; details are required on case authorship, selection criteria, and steps taken to avoid post-hoc tailoring to the DeepTrap optimization method, as artificial or easily surfaced cases would undermine the demonstration that final-response evaluation is insufficient in realistic deployments.
  2. [Evaluation methodology] Evaluation methodology: the abstract and evaluation sections supply no information on how attack and utility grading scores are computed, whether statistical significance was assessed, what baselines were used, or how post-hoc result selection was avoided. These omissions are load-bearing for the reported positive results and the conclusion that execution-context attacks evade final-response checks.
minor comments (1)
  1. [Abstract] The abstract would benefit from a single quantitative highlight (e.g., average attack success rate or number of models showing the effect) to give readers an immediate sense of effect size.

  1. Referee: [Benchmark construction] Benchmark construction (42 cases, six vulnerability classes, seven scenarios): the central claim that contextual compromise induces substantial unsafe behavior rests on this benchmark; details are required on case authorship, selection criteria, and steps taken to avoid post-hoc tailoring to the DeepTrap optimization method, as artificial or easily surfaced cases would undermine the demonstration that final-response evaluation is insufficient in realistic deployments.

    Authors: We agree that explicit details on benchmark construction are required to support the central claims. The 42 cases were developed by the authors prior to the design of DeepTrap, drawing from established vulnerability patterns in agentic systems and documented operational scenarios in the literature. Authorship followed a structured process: each case was created to instantiate one of the six vulnerability classes within one of the seven scenarios, with independent validation that standard agents could complete the benign task. Selection criteria emphasized diversity, realism, and coverage rather than optimization compatibility. To prevent post-hoc tailoring, benchmark finalization preceded any development or testing of the trajectory optimization method. We will add a dedicated subsection describing the case development workflow, selection criteria, and independence safeguards, including representative case examples. revision: yes

  2. Referee: [Evaluation methodology] Evaluation methodology: the abstract and evaluation sections supply no information on how attack and utility grading scores are computed, whether statistical significance was assessed, what baselines were used, or how post-hoc result selection was avoided. These omissions are load-bearing for the reported positive results and the conclusion that execution-context attacks evade final-response checks.

    Authors: We acknowledge the omission of methodological specifics in the current version. Attack grading scores are computed as the fraction of trajectories in which the targeted risk is realized (via risk-conditioned evaluators) while the benign task remains completed; utility grading scores are computed as the fraction of trajectories in which the original user task succeeds, assessed by a combination of rule-based verification and LLM-as-judge semantic checks. Statistical significance was assessed via paired t-tests over five independent runs with different seeds. Baselines consist of a no-attack condition and a random context perturbation baseline. All 42 cases and nine models are reported in aggregate without selective omission. We will expand the evaluation section with precise score definitions, formulas, statistical procedures, baseline descriptions, and an explicit statement on aggregation practices to preclude post-hoc selection. revision: yes

Circularity Check

0 steps flagged

No circularity: empirical evaluation framework with external benchmark and model evaluations

full rationale

The paper introduces DeepTrap as a black-box optimization framework for discovering contextual vulnerabilities and evaluates it on a separately constructed 42-case benchmark across vulnerability classes and scenarios. No equations, derivations, or first-principles predictions are present that reduce to self-defined inputs, fitted parameters renamed as outputs, or load-bearing self-citations. The central claim rests on external model evaluations and the benchmark's design, which is described as independently constructed rather than derived from the attack method itself. This is a standard empirical security evaluation paper with no self-referential reduction in its reported results.
