概述

Possible fields: newsletter opt-in names, emails and internal IDs. No passwords, cards or purchase history in that system. Count under review (count blank). No intrusion into DNP group systems. This stems from the Ymir Link Cuenote FC intrusion (recorded separately); the figure is a subset of the vendor scope and must not be added to it.
