ECLIPSE: Self-Evolving Stealthy Attack on Long-Horizon Agents

chaumian · x · 2026-09-02

This paper presents ECLIPSE, a self-evolving and stealthy prompt-injection framework targeting long-horizon agentic systems. It combines direct user-prompt injection with indirect tool-side injection using Stealthy Attack Trajectory Synthesis and Tool-Chain Steering. The authors also introduce LASE-Bench, a benchmark with 120 tasks for evaluating long-horizon agent safety.
