Trump Hotels has issued a statement that said it "may" have been a victim. It acknowledged that malware was at work at many of its hotels for over a year. Trump Hotels continued: "For customers that used credit or debit cards to make purchases between May 19, 2014, and June 2, 2015, we believe that the malware may have affected payment card data including payment card account number, card expiration date and security code." Hilton, for its part, issued a statement that said little. "Hilton Worldwide is strongly committed to protecting our customers' credit card information," the company said. "We have many systems in place and work with some of the top experts in the field to address data security. Unfortunately the possibility of fraudulent credit card activity is all too common for every company in today's marketplace. We take any potential issue very seriously, and we are looking into this matter." Security blogger Brian Krebs, who broke the Hilton news, insisted Hilton likely has in fact been breached.
