McDonald’s has become the latest company to be hit by a data breach after unauthorized activity on its network exposed the personal data of some customers in South Korea and Taiwan.
The fast-food giant said Friday that it quickly identified and contained the incident and that a thorough investigation was done.
“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,” the burger chain said.
McDonald’s said its investigation determined that only South Korea and Taiwan had customer personal data accessed, and that they would be taking steps to notify regulators and also the customers who may be impacted. No customer payment information was exposed.
McDonald’s said it will look at the investigation’s findings, coupled with input from security resources, to identify ways to further enhance its existing security measures.

And Colonial Pipeline, which transports about half of the fuel consumed on the East Coast, last month paid a ransom of 75 bitcoin — then valued at roughly $4.4 million — in hopes of getting its system back online. On Monday the Justice Department announced that it hadpayment.

National security adviser Jake Sullivan on Wednesday told reporters aboard Air Force One that President Biden would “100%” bring up cyberattacks in his upcoming meeting Russian President Vladimir Putin.
