Visitors who stayed at 14 Trump properties between the dates of August 10, 2016 and March 9, 2017, may have fallen victim to the hack.
Trump Hotels admitted that hackers stole credit card and other sensitive information about guests who stayed at 14 Trump properties via a breach of Sabre Hospitality Solutions, the third-party reservation booking system used by Trump Hotels.
Hackers have received "access to payment card information used for bookings in certain hotels, including the card holder's name, card number and perhaps the security code on the card", the company said.
"We recommend that affected guests review the information in this letter for some steps they can take to protect themselves against potential misuse of their information". The Trump Hotels' notice echoed Sabre's notice of data breach about the unauthorized access of Sabre Hospitality Solutions SynXis Central Reservation System.
The latest breach comes months after the Trump organization was forced to pay $50,000 to NY state after it failed to notify customers immediately after data breaches in 2015 led to the theft of at least 70,000 credit card numbers and 300 Social Security numbers.
The breach is part of a cyber attack on Sabre's systems disclosed in May.
According to a new report from The Washington Post, Trump Hotels has been hacked again.
'Then you look at Trump's hotels, and they're obviously a highly symbolic target'.
Still, that is better than when Trump Hotels learned of a May 2014 breach in June 2015, but did not notify guests until four months later.
There's a very interesting discussion going on in the United States right now about whether President Donald Trump and his family have been in touch with Russian government agents presumably tied to Russian hackers. The breach took place last month and the hotel was notified on June 5. More details on the breach can be found here.
Earlier this year, the InterContinental Hotel Group said guests' credit card data had been compromised at more than 1,200 of its properties, including Holiday Inn and Crowne Plaza hotels, over a three month period. "Well, because they're a good target", Peter W. Singer, a senior fellow at the New America Foundation, told the Washington Post.
While this incident may fall primarily on the company behind the reservations systems, Trump Hotel guests are not new to data breaches.
In May, Trump signed an executive order on cybersecurity created to hold the heads of federal agencies accountable for cybersecurity risks and breaches in their networks.
