McDonald’s reported a data breach that highlighted some personal information from customers in South Korea and Taiwan, the latest example of a global company that has been targeted by a hacker.
The Chicago burger chain said Friday that it has been able to identify and contain “recent unauthorized activity” on its network.
An investigation found “that a small number of files were accessed, some of which contained personal data,” the company said, adding that only customer information in South Korea and Taiwan was accessible.
McDonald’s said further measures will be taken in a few other markets to address leaflets containing information about its employees. No payment information was contained in the files that were accessed, the company added, saying it would notify regulators and customers affected by the breach.
McDonald’s violation has come amid a series of high-profile cyber attacks targeting companies in recent weeks. JBS, the largest meat processor in the world, has had its global operations hit by a to attack destined for the company’s IT systems, weeks after the Colonial Pipeline, a large U.S. fuel pipeline, was to be closed following a separate hacking incident.
Both JBS and Colonial attacks have involved the use of ransomware, in which hackers take control of a target’s computer systems or data by installing illegal software and demanding payment for the release of assets.
JBS said it paid $ 11 million to resolve the attack, U.S. officials said this week they recovered $ 2.3m cryptocurrency value paid as ransom to hackers who have closed the Colonial Pipeline.
The Colonial Pipeline incident highlighted the vulnerability of US infrastructure to cyber attacks and the Biden administration has promised to crack down on ransomware hackers, who have taken advantage of the rise of cryptocurrencies to facilitate and its operations.
Shares of McDonald’s rose more than 1 percent in New York trading on Friday to $ 237.30.
