Researchers have developed a new method called D-SCAN to detect poisoning attacks in retrieval-augmented generation (RAG) systems. These attacks involve injecting malicious documents into the RAG's context to manipulate its outputs. Traditional detection methods that rely on output uncertainty are often ineffective because poisoned generations can appear deceptively confident. D-SCAN, however, monitors the internal attention dynamics of the language model, identifying a phenomenon called "Attention Collapse" where attention becomes overly concentrated on poisoned documents. This framework is lightweight and has demonstrated effectiveness across various attack benchmarks, even detecting attacks that do not alter the final output. AI
