New AI attack poisons medical RAG systems with subtle misinformation

Researchers have developed a new knowledge poisoning framework called M extsuperscript{3}Att for medical multimodal retrieval-augmented generation (RAG) systems. This framework allows adversaries to inject misinformation into text data, using paired visual data as a trigger to manipulate retrieval without needing prior knowledge of user queries. The method aims to degrade diagnostic accuracy by introducing subtle errors that evade model self-correction, demonstrating clinical plausibility despite being incorrect. AI
