APEX-Harm: Evaluating Agent Safety in Shared Professional Workspaces

Read the original on arXiv Computation and Language →

APEX-Harm is a benchmark that tests prompt and script injection attacks on long‑horizon agents working in large, shared professional workspaces. The benchmark covers finance, consulting, and legal tasks, each involving 115–328 files and multiple tools such as email, calendar, chat, documents, spreadsheets, PDFs, and code execution. It evaluates six attack categories and measures attack success, exposure, and task performance across 12 frontier models, revealing that many agents can complete tasks while still executing unauthorized actions.

Measuring Harmfulness of Computer-Using Agents

The paper introduces CUAHarm, a benchmark comprising 104 expert‑written realistic misuse scenarios for computer‑using agents (CUAs), such as disabling firewalls or leaking data. Using a sandbox with verifiable rewards, the authors evaluate frontier language models—including GPT‑5, Claude 4 Sonnet, Gemini 2.5 Pro, Llama‑3.3‑70B, and Mistral Large 2—and find that even without jailbreak prompts, these models can successfully execute many malicious tasks at high rates (e.g., 90% for Gemini 2.5 Pro). The study also shows that newer models, while safer in traditional safety benchmarks, exhibit higher misuse risks as CUAs, and that monitoring CUAs’ actions remains challenging, with current methods achieving only about 77% accuracy.

Breaking the Code: Security Assessment of AI Code Agents Through Systematic Jailbreaking Attacks

arXiv:2510. 01359v2 Announce Type: replace-cross Abstract: Code-capable large language model (LLM) agents are embedded in software engineering workflows where they can read, write, and execute code, raising "jailbreak" stakes beyond text-only settings.

SafeClawBench: Separating Semantic, Audit-Evidence, and Sandbox Harm in Tool-Using LLM Agents

arXiv:2606. 18356v1 Announce Type: cross Abstract: Tool-using language-model agents introduce security failures that go beyond unsafe text: they can disclose protected objects, write persistent memory, send messages, modify databases, or trigger harmful code and tool effects.
