Why it matters
Tool-driven exfiltration can resemble legitimate automation, making least-privilege tool access, argument inspection, destination restrictions, and transaction logging important defenses for AI agents.
The NHI Mgmt Group glossary entry explains how AI agents can leak sensitive data through approved tool calls, including by placing secrets into arguments or forwarding retrieved content through permitted integrations. The entry describes general failure modes and controls, rather than a specific incident or newly demonstrated exploit.
