Hilton Worldwide has confirmed reports that the POS systems in some of its hotels’ restaurants were infected with malware that enabled hackers to steal credit card and other pieces of customer information.
The hotel operator and franchisor did not say how many restaurants or hotels were affected, but noted in a statement that the breaches lasted for three weeks last year and three months in 2015.
The lodging giant stressed that it has taken steps to strengthen the security of its information processing systems and has worked with authorities in investigating the malware placement.
The website KrebsOnSecurity reported five weeks ago that Hilton was suspected of having been hacked, but Hilton said at the time that it was investigating reports of a breach.
Hilton is a diversified, global lodging powerhouse. In addition to its namesake brand, the company’s chains include DoubleTree, Hampton Inns, Embassy Suites, Homewood Suites and Hilton Garden Inn.
