Climbing the Hill: Prompt Injection Red-Teaming Against Frontier Models with Curriculum Reinforcement Learning

Chenlong Yin, Xiaolong Jin, Wei Zou +2

Prompt injection is a leading security risk for LLMs and LLM-based applications such as agents. State-of-the-art red-teaming methods for prompt injection leverage reinforcement lea…

CleanBase: Detecting Malicious Documents in RAG Knowledge Databases

Weifei Jin, Xilong Wang, Wei Zou +2

Retrieval-augmented generation (RAG) is vulnerable to prompt injection attacks, in which an adversary inserts malicious documents containing carefully crafted injected prompts into…

Poison Once, Exploit Forever: Environment-Injected Memory Poisoning Attacks on Web Agents

Wei Zou, Mingwen Dong, Miguel Romero Calvo +7

Memory makes LLM-based web agents personalized, powerful, yet exploitable. By storing past interactions to personalize future tasks, agents inadvertently create a persistent attack…

AgentWatcher: A Rule-based Prompt Injection Monitor

Yanting Wang, Wei Zou, Runpeng Geng +1

Large language models (LLMs) and their applications, such as agents, are highly vulnerable to prompt injection attacks. State-of-the-art prompt injection detection methods have the…

PIShield: Detecting Prompt Injection Attacks via Intrinsic LLM Features

Wei Zou, Yupei Liu, Yanting Wang +3

LLM-integrated applications are vulnerable to prompt injection attacks, where an attacker contaminates the input to inject malicious instructions, causing the LLM to follow the att…

TracLLM: A Generic Framework for Attributing Long Context LLMs

Yanting Wang, Wei Zou, Runpeng Geng +1

Long context large language models (LLMs) are deployed in many real-world applications such as RAG, agent, and broad LLM-integrated applications. Given an instruction and a long co…

FCert: Certifiably Robust Few-Shot Classification in the Era of Foundation Models

Yanting Wang, Wei Zou, Jinyuan Jia

Few-shot classification with foundation models (e.g., CLIP, DINOv2, PaLM-2) enables users to build an accurate classifier with a few labeled training samples (called support sample…

MMCert: Provable Defense against Adversarial Attacks to Multi-modal Models

Yanting Wang, Hongye Fu, Wei Zou +1

Different from a unimodal model whose input is from a single modality, the input (called multi-modal input) of a multi-modal model is from multiple modalities such as image, 3D poi…
