Hilton Worldwide said Tuesday it has identified and eliminated malware that targeted customer card information during a 17-week period.
The attack on some of the lodging company's point of sale systems targeted cardholder names as well as card numbers, security codes and expiration dates. Hilton advised customers who used a payment card at one of its hotels from April 21 to July 27 of this year, or between Nov. 18 and Dec. 5 of last year, to review their statements.
"Hilton Worldwide is strongly committed to protecting customers' payment card information, and we sincerely regret any inconvenience this may have caused customers," the company said in a statement.
Hilton added that it has "further strengthened its systems" since identifying the attack.
The company's shares were unchanged in after-hours trading.
