If you notice an unknown person accessing a file in your VDR, it is important to review your data room's access permissions immediately. Check who has access to the folder and consider restricting or updating permissions to ensure only authorized individuals can view sensitive documents. You may also want to audit recent activity logs for any other unusual access. For further assistance and to ensure your data room is secure, visit [Decile Hub Support](https://decilehub.com/base/8-hub_support) for guidance or to contact support directly.
