said hackers stole some data from its systems in markets including the U.S., South Korea and Taiwan, in another example of cybercriminals infiltrating high-profile global companies.
The burger chain said Friday that it recently hired external consultants to investigate unauthorized activity on an internal security system, prompted by a specific incident in which the unauthorized access cut off a week after it was identified, McDonald’s said. The investigators discovered that company data had been breached in markets including the U.S., South Korea and Taiwan, the company said.
McDonald’s said attackers stole customer emails, phone numbers and addresses for delivery customers in South Korea and Taiwan. In Taiwan, hackers also stole employee information including names and contact information, McDonald’s said. The company said the number of files exposed was small without disclosing the number of people affected. The breach didn’t include customer payment information, McDonald’s said.
