A Las Vegas company that owns casinos in Colorado and three other states says its system for processing credit and debit card information has been hacked.
Affinity Gaming issued a statement Monday saying it has no evidence that credit card information was stolen. Company officials say they've taken steps to secure the system, and the independent cybersecurity firm Mandiant was looking into the breach.
The announcement comes a few months after Affinity reported a different cyberattack. The company said in December that its card processing system was infected with malware that compromised card data from customers.
Affinity owns 11 casinos, including three in Black Hawk -- Golden Mardi Gras Casino, Golden Gates Casino and Golden Gulch Casino.
