概述

The bank's own headcount is still under review (count blank). Names, gender, birth dates, addresses, phones, emails, driver-licence numbers, employer and contract data; ID-document images not included. This stems from the intrusion into SMBC Consumer Finance's guarantee system (recorded separately); the figure is a subset of that scope and must not be added to it.
