Merged summary

TL;DR - ToolHazard is a framework for automatically synthesizing adversarial, stateful tool environments to evaluate indirect prompt-injection risks in LLM agents. It enables broader security testing and generates alignment data that improves robustness without reducing benign-task utility.

  • Uses environment, attacker, and user simulators to create executable environments and long-horizon tasks.
  • Automatically discovers viable injection points and generates environment-specific attack payloads.
  • ToolHazard-Bench reveals substantial vulnerabilities, with attack effectiveness depending on injection timing and placement.
  • Generated alignment data improves security on ToolHazard-Bench and AgentDojo while preserving normal task performance.
