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…

Prompt Inference Attack on Distributed Large Language Model Inference Frameworks

Xinjian Luo, Ting Yu, Xiaokui Xiao

The inference process of modern large language models (LLMs) demands prohibitive computational resources, rendering them infeasible for deployment on consumer-grade devices. To add…

Passive Inference Attacks on Split Learning via Adversarial Regularization

Xiaochen Zhu, Xinjian Luo, Yuncheng Wu +3

Split Learning (SL) has emerged as a practical and efficient alternative to traditional federated learning. While previous attempts to attack SL have often relied on overly strong…
