McDonald's, the largest fast-food chain globally, has disclosed a data breach after hackers breached its systems and stole information belonging to customers and employees from the US, South Korea, and Taiwan.

As the world's global foodservice retailer, McDonald's serves almost hundreds of millions of customers every day in more than 39,000 locations in over 100 countries, including roughly 14,000 restaurants in the US alone.

McDonald's also told US employees that the attackers could only steal business contact info belonging to US employees and franchises that wasn't personal or sensitive, as first reported by WSJ. The threat actors also stole personal information from customers in South Korea and Taiwan,.

The number of customer documents exposed in the incident was small, and the breach did not impact customers' payment info in any way.

"Based on our investigation, only Korea and Taiwan had customer personal data accessed, and they will be taking steps to notify regulators and customers listed in these files."

"No customer payment information was contained in these files. In the coming days, a few additional markets will take steps to address files that contained employee personal data."
