The Trump hotel chain has disclosed that from May 19, 2014, and June 2, 2015 there has been malware on their payment system.

In a statement, it said: there “may have been unauthorized malware access to some of the computers that host our front desk terminals and payment card terminals in our restaurants, gift shops and other point-of-sale purchase locations.”

It is not known who the hackers were, but data stolen could include credit card account numbers, expiration dates, and security codes.

The hotels breached were in the cities of Chicago, Honolulu, Las Vegas, Toronto, and Miami, with two premises in New York City.

As a precautionary measure, the hotel chain is offering 12 months of free identity-theft protection. Customers are being cautioned to keep an eye on their credit and debit card transactions.

In many cases, the stolen data ends up being sold on illicit hacking forums, with buyers using it to purchase goods online or withdraw money from bank accounts.
