South Coast Winery Resort & Spa and Carter Estate Winery Resort reported a data breach involving unauthorized access to the Sabre Hospitality Solutions SynXis Central Reservations system. An unauthorized party gained access to account credentials, exposing unencrypted payment card information (cardholder name, number, expiration, and potentially security code) and guest PII (name, email, phone, address) for a subset of reservations. The breach occurred between August 10, 2016, and March 9, 2017. Sabre engaged a cybersecurity firm and notified law enforcement and payment card brands.
