Agent Security
Data Exfiltration
Also: exfil, data leakage
Moving data out of a protected environment to somewhere an attacker controls.
In more detail
For agents, exfiltration often rides on normal-looking behavior: a rendered image URL with a secret in the query string, a curl to an outside host, a commit pushed to the wrong remote, or a preview pane that fetches a link. Controls combine egress limits (which hosts the agent may reach), secret scanning on outputs and a record of every outbound action so a leak can be traced afterward.
