THE LETHAL TRIFECTA IN PRODUCTION: HOW ENTERPRISE COPILOTS QUIETLY BECAME EXFILTRATION TOOLS

Summary from the TLDR IT newsletter

Enterprise AI copilots face systemic data-exfiltration risks due to a "lethal trifecta," where a model accesses private data, processes untrusted content, and retains an outbound communication path. Documented vulnerabilities like EchoLeak in Microsoft 365 Copilot and ForcedLeak in Salesforce Agentforce demonstrate that attackers can exploit these flows via zero-click emails or public lead forms. Defenses must be structural, combining least-privilege scoping, deliberate rule-of-two limitations, and explicit outbound access controls rather than relying on classifiers or allowlists.
