Kentucky racing firm Churchill Downs has announced that they had to deal with a hacking crisis shortly after paying $885 million to take over Big Fish Gaming.
The attack occurred in December 2014, as a hacker installed malware on their site, syphoning off player information as the bug was contained in the company's billing and customer payment sections. Big Fish learned of the attack on January but failed to inform players until earlier this month.
In a letter to customer Big Fish wrote: "We have reported the incident to and are cooperating with law enforcement. We have also informed the credit reporting agencies and payment card networks about this incident so that they may take appropriate action regarding your card account."
Affected player information includes: names, addresses, payment card numbers, expiration dates, card verification codes and potentially other information.
