A Michigan casino recently reported a data breach that lasted for over seven months, representing the latest in a trend of merchant systems being affected by hackers.

Officials with the FireKeepers Casino in Battle Creak, Michigan announced last week that approximately 85,000 credit and debit card numbers were compromised in a breach that lasted from the beginning of this past September through the end of April.

According to the local NBC affiliate, casino staff were first notified of the issue on April 16 and worked to contain it, eliminating the threat within 10 days. 

The resulting investigation that cards used for food, beverage and retail purchases within the casino were affected in the seven month breach. FireKeepers' rewards club database as well as cards used for hotel reservations, cash advances and ATM transactions were not affected, as those use different payment processing systems. 

The investigation also discovered that an additional system that was also hacked during that period: the company's employee database. According to the local news source, the social security numbers, driver's license numbers and medical billing information of employees and their relatives were also compromised, though it is still unclear at this point whether the two incidents are connected or if the personal information was misused.

Since the breach, the casino has installed new payment processing equipment and increased security on all of their systems, adding new firewall protections and two-factor authorization.

FireKeepers is recommending customers continuously monitor their credit for any abnormalities and report suspicions charges to their bank.  Those affected are being offered free credit monitoring and identity protection services.
