According to Krebs, the luxury hotel chain - which is owned by the famous millionaire who just announced his presidential candidacy - was the victim of a credit card breach. Sources became hip to the hack after noticing a trend of stolen user credentials all leading back to a Trump Hotel property.
Krebs writes that sources from several banks "traced a pattern of fraudulent debit and credit charges to accounts that had all been used at Trump hotels." The breach could date as far back as last February.
The locations affected include Chicago, Honolulu, Las Vegas, Los Angeles, Miami, and New York.
This isn't the first hotel breach in recent memory. In fact, according to Krebs, luxury hotels Mandarin Oriental and White Lodging both reported data breaches in the last few months.
Business Insider contacted Trump Hotels about these allegations. We'll update as soon as we hear back.
