Hilton Worldwide is urging customers to check their credit card statements after confirming the theft of cardholder payment details.
The hotel chain said it has taken action to “eradicate” unauthorised malware that targeted payment information in some point-of-sale systems.
As a precautionary measure, Hilton has advised customers to review and monitor their statements if they used a payment card at a Hilton Worldwide hotel over a seventeen-week period, from November 18 to December 5 last year and April 21 to July 27 this year.
Hilton said malware had managed to access names, card numbers, security codes and expiration dates, but no addresses or PIN numbers were obtained.
In a statement, the group said it “sincerely regrets” any inconvenience caused to guests and it has launched an investigation and further strengthened its systems.
The attack comes days after Starwood announced 54 of its properties across America had been hit by malware (see news, November 22) and Marriott warned its customers against phone calls offering free stays at its hotels (see news, November 22).
