On Saturday, FireKeepers Casino Hotel in Battle Creek confirmed a recent unauthorized access into its computer systems.

85,000 credit and debit cards are at risk.

On April 16, 2015, FireKeepers learned of a possible security incident involving payment card information. FireKeepers brought in independent IT forensic experts to assist and has been cooperating with law enforcement.

The investigation is still ongoing, but it appears that approximately 85,000 credit and debit cards used between September 7, 2014, and April 25, 2015 for food, beverage and retail purchases may have been affected.

The information may include card number, cardholder name, verification code, and/or the card's expiration date. Patron information contained in the Red Hot Rewards Club database was not affected and remains secure. Cards used for hotel reservations, cash advances and ATM transactions, which are processed through separate systems, also were not affected. The security compromise has been contained and payment cards have been processed securely since April 26, 2015.

During the course of our investigation, on May 6, 2015, FireKeepers also determined that there may have been unauthorized access to a file storage server, which contained the personal information of certain customers, employees and their dependents. This data includes Social Security numbers and/or driver's license numbers. Health benefit selection and medical billing information of current and former employees and their dependents were also stored on this file server.

Neither FireKeepers nor its forensic investigators have found any evidence of unauthorized access or misuse of the personal information.  Potentially affected individuals will be receiving letters with information and resources and are encouraged to call (855) 861-4021 with any questions.

FireKeepers customers are encouraged to monitor their credit and debit card accounts, and contact their bank if they notice any suspicious activity.
