New ChainWatch framework detects multi-step attacks on AI agents

A new framework called ChainWatch has been developed to detect multi-step attacks targeting AI agent systems that use the Model Context Protocol (MCP). ChainWatch employs a six-stage kill chain model and a Hidden Markov Model (HMM) to analyze sequences of tool calls, identifying malicious progressions that bypass traditional per-call security measures. The framework is designed to counter direct sequential attacks, indirect prompt injection chains, and hybrid multi-stage attacks by extracting behavioral signals from tool interactions. AI

IMPACT Enhances security for AI agent systems by providing a novel method to detect complex, multi-step attacks.
