The staff member had entered the account credentials on a fake site linked from a phishing email posing as the platform operator; the account had no two-factor authentication and a weak password. Names, addresses, phone numbers, birth dates, emails, order counts and totals, and point histories of 136,464 people leaked. Card data and login passwords were not included. Its October 13 third report confirmed 136,464 affected people, including 109,311 whose address information was included.
