External Data Extraction Attacks against Retrieval-Augmented Large Language Models

Yu He, Yifei Chen, Yiming Li +5

In recent years, RAG has emerged as a key paradigm for enhancing large language models (LLMs). By integrating externally retrieved information, RAG alleviates issues like outdated…

Mitigating Many-shot Jailbreak Attacks with One Single Demonstration

Kejia Chen, Jiawen Zhang, Boheng Li +6

Many-shot jailbreaking (MSJ) causes safety-aligned language models to answer harmful queries by preceding them with many harmful question-answer demonstrations. We study why this a…
