In this episode, Ian Ahl (Permiso CTO) and Andi Ahmeti (Permiso Threat Researcher) walk through new research on how Microsoft Copilot email summaries can be manipulated by attacker-controlled content inside a message. They show how hidden instructions can influence summary output, inject fake security warnings, and make AI-generated summaries feel more trustworthy than the original email. It’s a sharp look at how productivity features can become attack surfaces, and what defenders should be watching next.
