Global hotel chain Hilton has revealed that it has been hacked and guests' credit card information has been stolen.

Hilton has not revealed the extent of the breach but it has confirmed that hackers have targeted payment card information at some of its point-of-sale hotel systems.

It has warned anyone who used credit cards at Hilton Worldwide hotels between November 18 and December 5 last year or April 21 and July 27 this year to watch for irregular activity in their accounts.

In a global press release, the hotel chain said it has worked with third-party forensics experts, law enforcement and payment card companies to conduct a thorough investigation.

NZME has asked New Zealand officials where guests staying in hotels here were affected.

The company's investigation has found the payment card information may have included cardholder names, payment card numbers, security codes and expiration dates, but no addresses or personal identification numbers (PINs).

"You have my personal assurance that we take this matter very seriously, and we immediately launched an investigation and further strengthened our systems," said Hilton global brands executive vice president Jim Holthouser.

"However, as a precautionary measure, some of you may wish to review payment card statements during certain time periods."

Hilton said the unauthorised malware targeted payment card information at Hilton Worldwide hotels.

The Hilton portfolio includes Hilton Hotels & Resorts, Waldorf Astoria Hotels & Resorts, Conrad Hotels & Resorts, Canopy by Hilton, Curio - A Collection by Hilton, DoubleTree by Hilton, Embassy Suites by Hilton, Hilton Garden Inn, Hampton by Hilton, Homewood Suites by Hilton, Home2 Suites by Hilton and Hilton Grand Vacations.
