HubScan: Detecting Hubness Poisoning in Retrieval-Augmented Generation Systems
Researchers introduce HubScan, an open-source security scanner that detects 'hubness poisoning' attacks in Retrieval-Augmented Generation (RAG) systems. The tool achieves 90% recall at detecting adversarial content that exploits vector similarity search vulnerabilities, addressing a critical security flaw in AI systems that rely on external knowledge retrieval.
