概述
About 150,000 entries contained one or more identifying fields; about 120,000 email entries are a subset. Roughly 1.68 million contained only non-identifying fields. These approximate record counts are not people totals and are not added. No card information was included. The credential-theft route is unknown; subsequent PHP reviews or form changes do not establish the entry cause.
