McDonald’s says breach exposed customer data in South Korea and Taiwan

McDonald’s has reported a data breach that exposed personal information of customers in South Korea and Taiwan, the latest example of a global business targeted by a hack.

The Chicago-based burger chain said Friday it was able to quickly identify and contain “recent unauthorized activity” on its network.

An investigation found “that a small number of files were viewed, some of which contained personal data,” the company said, adding that only customer information in South Korea and Taiwan was viewed.

McDonald’s said additional steps would be taken in a few other markets to process files containing information about its employees. No payment information was contained in the files viewed, the company added, saying it would notify regulators and customers affected by the breach.

The McDonald’s breach comes amid a spate of high-profile cyber attacks targeting businesses in recent weeks. JBS, the world’s largest meat processor, saw its global operations hit by an attack on the company’s computer systems, weeks after the Colonial Pipeline, a major U.S. fuel pipeline, had to be shut down at the following another hacking incident.

The JBS and Colonial attacks both involved the use of ransomware, in which hackers take control of a target’s computer systems or data by installing rogue software and demanding payment for the release of assets.

JBS said it paid $ 11 million to resolve the attack, while U.S. officials this week said it recovered $ 2.3 million in cryptocurrency paid in ransom to hackers who shut down the colonial pipeline.

The Colonial Pipeline incident exposed the vulnerability of the US infrastructure to cyberattacks and the Biden administration pledged to crack down on ransomware hackers, who have used the rise of cryptocurrencies to facilitate their operations. .

McDonald’s shares rose more than 1% in New York on Friday to $ 237.30.
