Trump Hotel Collection, the hotel business belonging to US Presidential hopeful Donald Trump, has fallen victim to an attack on its credit card systems, the company has confirmed, blaming the attack on "cyber terrorists".

The hack first came to light when banking sources told security researcher Brian Krebs they had noticed "a pattern of fraud on customer credit cards that suggests hackers have breached credit card systems at some - if not all - of the Trump Hotel Collection properties".

Also known as Trump Hotels, the business owns several luxury hotels located primarily in the US, but also Canada, Brazil and the UK.

In a statement to IT Pro, Eric Trump, Donald Trump's son and one of the co-managers of Trump Hotels, said: "Like virtually every other company these days, we are routinely targeted by cyber terrorists whose only focus is to inflict harm on great American businesses. We are in the midst of a thorough investigation on this matter and are working with the US Secret Service and the FBI to help catch these criminals and prosecute [them] to the full extent of the law."

"We are committed to safeguarding all guests' personal information and will continue to do so vigilantly," he added.
