google workspace users typically share drive resources with a shareable link where parameters are edited to indicate when it is viewable or editable by the intended recipient. it is uncommon for a user in an organization to manually copy a drive object from an external drive to their corporate drive. this may happen where users find a useful spreadsheet in a public drive, for example, and replicate it to their drive. it is uncommon for the copied object to execute a container-bound script either unless the user was intentionally aware, suggesting the object uses container-bound scripts to accomplish a legitimate task.
