Affinity Gaming recently announced that hackers breached the system used to process credit and debit cards for its casinos, and may have accessed the personal information of customers who visited any of a variety of Affinity gaming locations between March 14, 2013 and October 16, 2013.

The system used to process credit and debit cards at Affinity's Prism Center Gas Station in Primm, Nev., was also breached, beginning on an unknown date and ending on November 29, 2013.

SC Magazine reports that between 280,000 and 300,000 people were affected.

The company was contacted by law enforcement on October 24, 2013, regarding fraudulent charges that appeared to be linked to a data breach in Affinity's system.

Third-party forensic experts then determined that malware planted on Affinity's system resulted in the theft of credit card and debit card information for people who visited any of the following Affinity locations: Silver Sevens Hotel & Casino in Las Vegas, Nev.; Rail City Casino in Sparks, Nev.; Primm Valley Resort & Casino in Primm, Nev.; Buffalo Bill's Resort & Casino in Primm, Nev.; Whiskey Pete's Hotel & Casino in Primm, Nev.; Lakeside Hotel-Casino in Osceola, Iowa; St. Jo Frontier Casino in St. Joseph, Mo.; Mark Twain Casino in LaGrange, Mo.; Golden Gates Casino in Black Hawk, Colo; Golden Gulch Casino in Black Hawk, Colo; and Mardi Gras Casino in Black Hawk, Colo.

"Affinity is cooperating in the ongoing law enforcement investigation of the incident," the company said in a statement. "Affinity has also taken a number of measures to strengthen the security of our network and it has worked with legal and security vulnerability experts to help identify and implement additional appropriate safeguards."

While no identity theft protection services are being offered to those affected, the company is advising all those affected to place fraud alerts on their credit files.

Customers with questions are advised to contact (877) 238-2179.
