Researchers have developed a novel reference monitor designed to detect and prevent covert channels used by compromised Large Language Model (LLM) agents to leak data. The system employs a multi-stage text processing pipeline and media scrambling techniques for audio and images to eliminate hidden data transmission. It uses cryptographic attestations to distinguish legitimate media from data disguised as media, and measures residual capacity to ensure covert channels are destroyed or bounded. AI
