Luxury hotel chain Loews Hotels is warning some customers that a data breach may have resulted in financial information being stolen.
Hackers obtained access to credit card, security code and password information through a third-party company, Sabre, which provides booking services through travel agencies, websites and other mediums, the hotel chain said. In some cases, email, phone number and street addresses were also taken.
Highly-sensitive information like Social Security numbers and passport information was not affected.

The unauthorized access was ongoing for seven months between August 2016 and March 2017. Sabre told Lowes about the breach in June.
In a statement, Sabre said less than 15 percent of the average daily bookings were viewed by the hackers.
Customers who may have had their information taken are advised to monitor their credit card statements and credit report for fraudulent activity and reach out to the credit card company if any suspicious activity is noticed.
