Présentation

Arara first said on October 29 that Workman data was not included, then reported on November 2 that it was. Only email addresses ("up to about 1.45 million") were involved; count left blank. 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.
