Large Language Model (LLM) agents have become increasingly prevalent across various real-world applications. They enhance decision-making by storing private user-agent interactions in the memory module for demonstrations, introducing new privacy risks for LLM agents. In this work, we systematically investigate the vulnerability of LLM agents to our proposed Memory EXTRaction Attack (MEXTRA) under a black-box setting. To extract private information from memory, we propose an effective attacking prompt design and an automated prompt generation method based on different levels of knowledge about the LLM agent. Experiments on two representative agents demonstrate the effectiveness of MEXTRA. Moreover, we explore key factors influencing memory leakage from both the agent designer's and the attacker's perspectives. Our findings highlight the urgent need for effective memory safeguards in LLM agent design and deployment.

  1. Isolated but Exposed: Persistence-Based Memory Extraction Attack on LLM Agents

    cs.CR 2026-07 conditional novelty 7.5 of 10

    Malicious tools can systematically extract isolated LLM-agent long-term memory via persistence, pure-anchor retrieval steering, and reactivation payloads, reaching 80% extraction with unlimited triggers and 47% with 20.

  2. Towards Aligning Personalized Conversational Recommendation Agents with Users' Privacy Preferences

    cs.HC 2025-08 conditional novelty 5.0 of 10

    Privacy management for conversational AI agents is reframed as a dynamic alignment problem in which agents learn a user's latent privacy-utility reward function from feedback.

  3. LLM Agents Should Employ Security Principles

    cs.CR 2025-05 conditional novelty 5.0 of 10

    A position paper proposing AgentSandbox, a framework that applies Saltzer-Schroeder security principles to LLM agents and reports large attack-success-rate reductions on AgentDojo.

  4. A Survey on Autonomy-Induced Security Risks in Large Model-Based Agents

    cs.AI 2025-06 conditional novelty 4.0 of 10

    The paper surveys security risks of LLM agents, organizes them into a five-level autonomy taxonomy, and proposes an untested CMDP-based architecture called R2A2.

  5. A Survey on Agent Workflow -- Status and Future

    cs.AI 2025-08 conditional novelty 3.0 of 10

    A review that classifies 24 agent workflow systems along functional and architectural axes and argues for standardization, optimization, and security work.
