The Trump Hotels chain has once again suffered a data breach involving credit card information.

A notice posted on its website earlier this week, explained that an unauthorized party had gained “access to guest information associated with certain hotel reservations.” The incident occurred on a reservation system provided by Sabre Hospitality Solutions (Sabre). The unauthorized party accessed:

Payment card information

Guest names

Email addresses

Phone numbers

Postal addresses

And other information.

The notice read:

“The Sabre SynXis Central Reservations system (CRS) facilitates the booking of hotel reservations made by consumers through hotels, online travel agencies, and similar booking services. Following an investigation, Sabre notified us on June 5, 2017 that an unauthorized party gained access to account credentials that permitted access to payment card data and certain reservation information for some of our hotel reservations processed through Sabre’s CRS.

The investigation found that the unauthorized party first obtained access to Trump Hotels-related payment card and other reservation information on August 10, 2016. The last access to this information was on March 9, 2017.”

Hard Rock Hotels and Loews Hotels were also affected.
