McDonald’s Corp, the world’s largest hamburger chain, said on Friday that a data breach in South Korea and Taiwan exposed some customer and employee information, making it the latest global company to target of cybercriminals.
The details of the breach in both regions are the result of an investigation by outside consultants following unauthorized activity on the company’s network.
“Although we were able to quickly close access after identification, our investigation determined that a small number of files were accessed, some of which contained personal data,” McDonald’s said in a statement.
The company said it will take steps to notify regulators and customers listed in the files that did not contain customer payment information.
Recent breaches by cybercriminals at hospitals and companies worldwide, including meat processor JBS and Colonial Pipeline Oil, have disrupted operations for hours, leading to concerns of supply shortages.
Some companies had to pay a ransom to gain control of their operations and restart production.
McDonald’s said it would use the investigation’s findings to identify ways to improve its security measures.
