Overcoming the Retrieval Barrier: Indirect Prompt Injection in the Wild for LLM Systems

Hongyan Chang, Ergute Bao, Xinjian Luo +1

Large language models (LLMs) increasingly rely on retrieving information from external corpora. This creates a new attack surface: indirect prompt injection (IPI), where hidden ins…
