McDonald's hit by data breach impacting some customer information in Asia

The burger chain said there was no interruption to operations.

McDonald's said Friday there was no interruption to its operations after it incurred a data breach that comes amid a concerning string of cyberattacks aimed at high-profile targets. The company said that it worked with "experienced third parties" to conduct a "thorough investigation" after identifying unauthorized activity on its network. "While we were able to close off access quickly after identification, our investigation has determined that a small number of files were accessed, some of which contained personal data," McDonald's Corporation said in a statement to ABC News. Their investigation found customer personal data in Korea and Taiwan had been accessed by the hackers, but said no files contained customer payment information. The company said that it will be "taking steps to notify regulators and customers listed in these files."
