McDonald’s, the world’s largest burger chain, said on Friday that a knowledge breach in South Korea and Taiwan has exposed some customer and employee information, making it the newest global company to be targeted by cybercriminals.
The attackers accessed e-mails, phone numbers, and delivery addresses, but the breach didn’t include customer payment information, the corporate said.
The details of the breach within the two regions were the results of an investigation by external consultants following an unauthorized activity on the company’s network.
“While we were ready to close off access quickly after identification, our investigation has determined that a little number of files were accessed, a number of which contained personal data,” McDonald’s said in s statement.
The burger chain said it’ll take steps to notify regulators and customers listed within the files.
Recent breaches by cybercriminals on hospitals and global companies including meat processor JBS and Colonial Pipeline oil have disrupted operations for hours, resulting in worries of supply shortages.
A few companies have had to pay a ransom to realize control of their operations and restart production. McDonald’s said its day-to-day operations weren’t affected which a ransom wasn’t involved.
The company said it might use the findings from the investigation to spot ways to enhance its security measures.
