Customers who stayed at a Hilton Worldwide hotel may have had their credit card information violated by malware that infected the company's computer systems.
The malware infected the point-of-sale computers in some hotels between November 18 to December 5, 2014 or April 21 to July 27, 2015.
Hilton says that the taken information may have included cardholder names, payment card numbers, security codes and expiration dates, but no addresses or personal identification numbers.
The company advises customers to contact their banks directly if they notice a violation on their accounts, and Hilton is offering complimentary one-year credit monitoring to customers.

Message to Our Valued Customers,
On behalf of Hilton Worldwide, we sincerely regret any inconvenience related to our recent announcement that we identified and eradicated unauthorized malware that targeted payment card information in some point-of-sale systems at our hotels. You have my personal assurance that we take this matter very seriously, and we immediately launched an investigation and further strengthened our systems. However, as a precautionary measure, some of you may wish to review payment card statements during certain time periods.
You may want to review and monitor your payment card statements if you used a payment card at a Hilton Worldwide hotel over a seventeen-week period, from November 18 to December 5, 2014 or April 21 to July 27, 2015. If you notice any irregular activity on your cards, please contact your financial institution directly for additional support.
We have worked with third-party forensics experts, law enforcement and payment card companies to conduct a thorough investigation. As a result of this investigation, we have determined that 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).
Please refer to these Frequently Asked Questions for additional information, and click here (beginning noon CST, Nov. 25, 2015) for complimentary one-year credit monitoring that we are offering. We deeply appreciate your understanding as we work to protect your payment card information.
Executive Vice President, Global Brands
