In September 2014, Viator said a payment provider alerted it to unauthorized card charges. The company was investigating a breach that potentially affected about 1.4 million customers: roughly 880,000 may have had payment-card details exposed and another 560,000 account information. Viator hired forensic experts, notified law enforcement and offered U.S. customers identity-protection services. The cause remained unknown.
