Fast food giant McDonald’s Corp. was attacked by hackers that stole data from systems in at least three of its markets, the WSJ reported.

  • McDonald’s said the hackers were able to gain access to business contact information of employees and franchisees in the United States, on top of data on logistics such as seating capacity and square footage of play areas.
  • Hackers also stole emails, phone numbers, and addresses of delivery customers in South Korea and Taiwan. Employee information such as identities and contact details were also accessed in Taiwan.
  • McDonald’s said the number of exposed files was small and did not include customer payout information. It is coordinating with regulators in the affected markets, and warned others of possible attempts.

The company said business was not disrupted, and has not received any demand for ransom nor made any payment in exchange for the files. MCD is up 1.13%.
