Provider account; sensitive-data theft not established.
Activity date undisclosed.

Editorial connections. The evaluation operator owns the agent controls; the outside organization owns its service. These are not claims about missing controls or guaranteed prevention.
The operator can restrict destinations and require explicit approval for external actions, including submissions.
Instructions alone cannot reliably enforce a boundary. Controls must also cover unexpected workarounds.
Review public applications for unintended file access and command execution, then verify deployed fixes.
Finding a weakness does not prove it has been fixed everywhere.
