AgentPoison: A Novel Red Teaming Approach and Backdoor Attack Targeting Generic and RAG-based LLM Agents by Poisoning their Long-Term Memory or RAG Knowledge Base

Practical Solutions and Value of AGENTPOISON: A Novel Red Teaming Approach

Overview

Recent advancements in large language models (LLMs) have enabled their use in various critical areas such as finance, healthcare, and self-driving cars. However, the trustworthiness of these LLM agents remains a concern due to potential vulnerabilities in their knowledge bases.

Security Against Attacks

Attacks on LLMs, such as jailbreaking and backdooring, are inefficient against agents using retrieval-augmented generation (RAG). This provides a strong defense against malicious content injection and ensures a high level of security.

AGENTPOISON Method

Researchers have introduced AGENTPOISON, a backdoor attack targeting generic LLM agents based on RAG. This method corrupts the agent’s knowledge base with harmful examples, causing the agent to produce adversarial outcomes when triggered.

Real-World Impact

Experiments on self-driving cars, knowledge-based question answering, and healthcare record management agents demonstrate AGENTPOISON’s high attack success rate and minimal impact on benign performance. It outperforms other methods and remains effective across different scenarios.

Practical Implementation

AGENTPOISON offers a practical and reliable red-teaming method to evaluate the safety and reliability of RAG-based LLM agents. It does not require model training and has a highly adaptable and stealthy trigger, making it suitable for real-world applications.
