Hotel firm Hyatt has suffered a security breach affecting computer systems used at the properties it manages.
The US-based firm announced that it had found malware on computers used to operate payment processing systems, but the problem has now been fixed.
Chuck Floyd, Hyatt's global president of operations, said: “As soon as we discovered the activity, we launched an investigation and engaged leading third-party cyber security experts.
“We have taken steps to strengthen the security of our systems, and customers can feel confident using payment cards at Hyatt hotels worldwide.
“Protecting customer information is of critical importance to Hyatt, and we take the security of your payment card data very seriously.”
Earlier this year, both Hilton and Starwood revealed that they had been affected by malware attacks on their systems.
Hyatt said the investigation was “ongoing” and advised customers to check their card statements for any unauthorised charges.
“Payment card rules generally provide that cardholders are not responsible for unauthorised charges that are timely reported,” added Hyatt.
