McDonald’s (MCD) said its systems were hacked in South Korea and Taiwan, with cybercriminals garnering information about the fast-food goliath’s customers, employees and business.
The company discovered “a small number of files were accessed, some of which contained personal data,” the company said in a statement, Bloomberg reports.
McDonald’s said no customer-payment information was part of the purloined material.
The hackers got business-contact information for U.S. employees and franchisees in addition to information about restaurants, such as seating capacity and the size of play areas, McDonald’s said, according to The Wall Street Journal.
McDonald’s stock recently traded at $236.82, up 1%. It has climbed 14% over the past six months amid optimism about economic recovery.
