Donald Trump's luxury hotel chain has confirmed that seven of its properties were the target of a data breach earlier this year that potentially exposed customer debit and credit card information.
In a legal notice posted on its website, the Trump Hotel Collection said the hack could affect people who used their cards between May 19, 2014, and June 2, 2015, at Trump SoHo New York, Trump National Doral in Miami, Trump International New York, Trump International Chicago, Trump International Waikiki, Trump International Hotel & Tower Las Vegas, and Trump International Toronto, NBC News reports.
According to Trump Hotels, hackers placed special software on the hotel chain's payment systems. That malware touched sensitive payment information, like credit card numbers, expiration dates and security codes on the back of cards.
It seems that, as customers or hotel employees typed in payment information, the malicious software quietly grabbed it in the background. But the company isn't quite sure if the hackers managed to pull out that data from the computer system, CNN Money reports.
"An independent forensic investigation has not conclusively determined that any particular customer's payment card information was taken," the company stated.
The hotel chain is offering one year of free identity fraud protection to affected customers.
