Issue
- We found the user ddm_form_default_user_screen_name in our Liferay Portal.
- Could it be a security attack?
Resolution
- The user with name ddm_form_default_user_screen_name is an internal user automatically created by Liferay.
- When there is a page that contains a form with the Upload element set to Allow Guest Users to Send Files, the portal automatically creates the user ddm_form_default_user_screen_name with status Inactive.
- There is no reason to be concerned, this is an expected behavior.
