The Yak and Yeti restaurant at Animal Kingdom, which is operated by Landry's has released information about the compromisation of transactions between 8th May 2015 and 3rd December 2015. See below for Landry's press release;
"Findings from the investigation show that criminal attackers were able to install a program on payment card processing devices at certain of our restaurants, food and beverage outlets, spas, entertainment destinations, and managed properties. The program was designed to search for data from the magnetic stripe of payment cards that had been swiped (cardholder name, card number, expiration date and internal verification code) as the data was being routed through affected systems. Enhanced security measures, including end-to-end encryption, have been implemented to prevent a similar issue from occurring in the future, and we continue to support law enforcement’s investigation. We are also working closely with the payment card networks to identify potentially affected cards so that the card issuers can be made aware and initiate heightened monitoring of those accounts. For those customers we can identify as having used their card at an affected location during that location’s at-risk window and for whom we have a mailing address or e-mail address, we will be mailing them a letter or sending them an e-mail."
