Hotel chain operator Hilton Worldwide Holdings said on Tuesday US time it identified unauthorised malware in some payment systems that targeted payment card information.
A third-party investigation found that the malware targeted specific payment card information, that included cardholder names, payment card numbers, security codes and expiration dates, Hilton said.
The information targeted, however, did not include addresses or personal identification numbers (PINs), the company added.
Hilton said customers who used their cards during a 17-week period - from 18 November to 5 December 2014 or 21 April to 27 July 2015 - were advised to check their bank statements.
The owner of the Conrad and Double Tree hotel chains did not provide details on the number of cards affected.
The news comes less than a week after rival Starwood Hotels & Resorts said that 54 of its hotels in North America had been infected with a malware designed to collect payment card data.
Shares of the company were unchanged in extended trading on Tuesday US time. They closed at US$23.45 on the New York Stock Exchange.
