Title: DRIFT: Dynamic Rule-Based Defense with Injection Isolation for Securing LLM Agents

Abstract:
arXiv:2506.12104v3 Announce Type: replace-cross Abstract: Large Language Models (LLMs) are increasingly central to agentic systems due to their strong reasoning and planning capabilities. By interacting with external environments through predefined tools, these agents can carry out complex user tasks. Nonetheless, this interaction also introduces the risk of prompt injection attacks, where malicious inputs from external sources can mislead the agent's behavior, potentially resulting in economic
