McDonald’s, one of the world’s largest food franchises, has been added to the list of high-profile companies that have experienced a data breach in the last month. Hackers stole data from its databases in the United States, South Korea, and Taiwan. Investigations revealed that corporate data had been compromised in these locations. To further investigate, the company employed private experts to analyze illegal activity on the security and intelligence system triggered by a particular incident. Fortunately, the McDonald’s data breach was terminated a week after it was discovered.
