In short, they got hacked. During this time, guest information related to a subset of hotel reservations (unencrypted payment card information, reservation information) booked through Sabre's SynXis central reservations system was accessible by an unauthorized party.
Locations affected by the breach include the Trump properties in Central Park; Chicago; Doonbeg; Doral; Las Vegas; Panama; Soho; Toronto; Turnberry; Vancouver; Waikiki; Washington, D.C.; Rio De Janeiro; and the Albemarle Estate in Charlottesville, Virginia.
The organisation noted that Social Security numbers, passports and driver's licence numbers were not accessed in the breach. "This incident occurred on the systems of Sabre Hospitality Solutions (Sabre), a service provider used by Trump Hotels". According to the company's announcement, the cyber attack has hit the Saber Hospitality Solutions system, which is used by Trump Hotels, Nova TV reported. Four Seasons Hotels and Resorts, Hard Rock Hotels and Casinos, Loews Hotels and Carlson Wagonlit Travel were also affected by the breach. The stolen records included guests' full names and credit-card numbers, expiration dates and security codes, as well as email addresses, phone numbers and home addresses.
"We are working with Sabre to address this issue", Trump Hotels wrote in a press release. "Sabre indicated that they also notified law enforcement and the payment card brands about this incident".
"The privacy and protection of our guests' information is a matter we take very seriously", the notice said. "We apologize for any inconvenience caused by this incident".
The hack is the third time a months-long security snafu has affected guests of the chain of luxury hotels. Cheaper hotels might prove a less attractive target, but really, wherever there's a large group of people's names and credit-card information, opportunistic criminals won't be too far behind. More details on the breach can be found here.
The attack "did not affect Trump Hotels' systems", the statement reads. Given yet another disclosure of a hotel using Sabre software being hacked, this may actually be the tip of the iceberg in terms of a widespread hacking campaign that may involve many other hotel chains as well.
Trump International Hotels Management paid the state of NY over $50,000 in penalties previous year after failing to immediately notify guests that their personal information had been breached.
