RAG systems are vulnerable to hubness poisoning attacks that can lead to misleading data retrieval and compromised AI output, which can have severe security implications.
Transform HubScan into a plug-in or standalone security tool for AI-driven applications that utilize RAG systems, with integration options for common vector databases like FAISS and Weaviate.
Replaces manual oversight and traditional security protocols in AI systems which are ineffective in real-time detection of hubness attacks, offering automated, proactive threat detection.
The need to secure RAG systems in enterprises using AI for decision support creates a large market valued in the cybersecurity sector, where companies will pay to ensure data integrity and system reliability.
Commercial cybersecurity software for companies using RAG systems to prevent data poisoning attacks, ensuring reliable AI outputs.
HubScan uses robust statistical methods such as median/MAD-based z-scores to detect anomalous hubs in vector indices, which act as attractors in high-dimensional spaces, often used maliciously to insert misleading or harmful content.
Tested on adversarial datasets (Food-101, MS-COCO) and real-world data (MS MARCO) with strong performance metrics reaching 100% recall for targeted detection scenarios.
The system might encounter challenges with evolving adversarial tactics or new attack forms that bypass current detection methods. Continuous update and adaptation will be necessary.
