概述

12,211 addresses were registered by November 4, but the city says whether and how many actually leaked is still under investigation, so the count field is left blank. No other fields reportedly at risk. No intrusion into the reservation system itself. This stems from the Arara email-platform intrusion (recorded separately); the registration pool is a subset of the vendor scope and must not be added to it.
