Waseda confirms acquisition of 3,342 authentication-related user records

Resumen

This publisher-stated total comprises 81 individually obtained entries and 3,261 staff-related sets. It counts records, not unique people, because users can have multiple email addresses. Additional acquisition remains under investigation. Admissions and Open College impacts were not confirmed. A PHP-related review revealed the incident but does not establish PHP as the entry cause.
