The Hyatt Hotels group has warned that it has found malicious software on the computer system that processes guest credit card payments, with customer details potentially at risk.
according to The Guardian newspaper today.
The group warned customers to check their bank statements and said it would offer updates on its website.
Spokesperson Stephanie Sheppard has stated: "The investigation is ongoing, and we'll have more information once it is complete."
The group joins other hotel groups Starwood Hotels & Resorts and Hilton Worldwide in being hit by hackers and malware in recent weeks, after both the Marriott International-owned Starwood, and Hilton, found malware of its point-of-sale systems in late November.
