Hotel properties owned by Donald Trump’s Trump Organization are the latest consumer-facing businesses to become the subject of a cybercrime, with the company acknowledging that a data breach has occurred at locations run by the Trump Hotel Collection.

KrebsOnSecurity.com first reported, and subsequently confirmed, news of the data breach at Trump hotel locations in multiple cities, including New York, Chicago, Las Vegas, Los Angeles, Honolulu, and Miami.

In a statement to the site, Eric Trump, an executive VP with the company, explained that, “Like virtually every other company these days, we have been alerted to potential suspicious credit card activity and are in the midst of a thorough investigation to determine whether it involves any of our properties.”

The statement does not indicate how long the breach had gone on for or how long the Trump organization had known about it. According to Krebs’ sources, it looks like the theft extends at least as far back as Feb. 2015, though there is still no mention of the number of compromised accounts or how many fraudulent transactions were made before banks caught on.

Bank sources told the site that financial institutions had been investigating a rash of fraudulent credit card purchases and found that the accounts in question had all previously been used at a Trump location.
