A Hilton statement said customers who used their cards during a 17-week period - from November 18 to December 5, 2014 or April 21 to July 27, 2015 - were advised to check their bank statements.
The news follows a similar incident at Starwood Hotels & Resorts Worldwide Inc that said 54 of its hotels in North America had been infected with malware designed to collect payment card data.
Hilton Worldwide Holdings shares were unchanged in extended trading on Tuesday, closing at US$23.45 on the New York Stock Exchange.
