Overview

Possible fields: emails, names and affiliations. No count (count blank). The operator's investigation had not yet listed the foundation among confirmed victims, but the notice still treats exposure as possible while the probe continues. This stems from the Rakus Light Cloud Blastmail intrusion (recorded separately); the figure is a subset of the vendor scope and must not be added to it.
