McDonald's Corporation

McDonald's is a fast-food restaurant chain that primarily offers hamburgers, cheeseburgers, chicken products, french fries, soft drinks, breakfast items, and desserts. It operates through a mix of company-owned and franchised locations, serving customers in many countries worldwide. The menu is adapted to local tastes while maintaining core offerings.

The company is recognized for its standardized operating procedures, strong brand identity, and extensive supply chain network that supports consistent product quality across markets. Its business model emphasizes franchising, enabling rapid expansion and local entrepreneurship while maintaining corporate oversight. McDonald's also invests in technology for ordering, payment, and customer engagement, such as mobile apps and self-service kiosks.

In June 2021, McDonald's disclosed a data breach in which attackers accessed internal systems. The breach compromised U.S. business information such as restaurant square footage. It also exposed personal data of customers in South Korea and Taiwan, including delivery customer emails, phone numbers, and addresses. Employee names and contact details were stolen in Taiwan. Upon discovery, the company promptly terminated the unauthorized access. McDonald's engaged external consultants to investigate the incident. The organization advised staff and franchisees to remain vigilant against phishing attempts. It also addressed affected employee data files in additional markets.
