Top 10 zero-click attacks against AI agents
"Securing Agentic AI: From Per-Action Checks to Trajectory Assurance" argues that per-action approval prompts and human-in-the-loop checks fail against zero-click agent attacks, and advocates monitoring the full agent trajectory instead. Drawing on documented cases such as the EchoLeak (CVE-2025-32711) Microsoft 365 Copilot zero-click exfiltration, the Morris-II self-replicating GenAI worm, and A2A protocol risks, it proposes treating retrieval as untrusted, scoping agent identities, and logging at the agent runtime.
