概述

786,739 email addresses and 2,352 names (some delivery-service customers) leaked; the names may overlap with the email set and are not added. Addresses, phones and payment data are not held. Per the company, this stems from unauthorised access to the Arara email-delivery platform (recorded separately); this figure is a subset of the vendor scope and must not be added to it.
