Hasbro Discloses Cyberattack Disrupting Operations and Shipments
Toy and entertainment giant Hasbro revealed in a Securities and Exchange Commission (SEC) filing on Wednesday that a cyberattack has disrupted its ability to process orders and ship products. The company’s IT team detected unauthorized access on March 28, prompting immediate containment efforts, including taking some systems offline.
Hasbro has activated business continuity plans to maintain key operations while addressing the incident, though delays are expected to persist for several weeks. The company is also reviewing potentially impacted files to determine whether regulatory notifications are required. No hacking group has claimed responsibility as of Monday, and an investigation remains ongoing.
The attack adds Hasbro to a growing list of companies including Nucor, Masimo, and Clorox that have reported operational disruptions following cyber incidents in recent months. With $4.7 billion in 2025 revenue, Hasbro ranks among the largest toy and intellectual property manufacturers globally. The sector has seen prior ransomware attacks, with companies like Jakks Pacific and Bandai Namco targeted in previous years.

Ransomware Attack Disrupts Jaguar Land Rover Operations as Cyber Threats Surge Across Industries
Jaguar Land Rover (JLR), the UK-based automaker owned by India’s Tata Motors, confirmed a ransomware attack that severely disrupted its retail and production operations. In a statement released Tuesday, the company revealed it had taken immediate action to contain the incident by proactively shutting down systems. While JLR reported no evidence of customer data theft, it is working to restore global applications in a controlled manner.
The attack is part of a broader wave of cyber incidents targeting critical industries. U.S. steelmaker Nucor also recently experienced a cybersecurity breach, forcing a shutdown of some production lines. The insurance sector has been particularly hard hit, with Aflac, Philadelphia Insurance Companies, and Erie Insurance all falling victim to attacks this summer.
Grocery supply chains have not been spared United Natural Foods Inc. (UNFI), a distributor for Whole Foods and other retailers, disclosed a cyber incident in July that temporarily disrupted operations. Meanwhile, the FBI issued a warning last month about the cybercriminal group "Scattered Spider," which has been targeting airlines. Hawaiian Airlines confirmed a June cybersecurity event affecting its IT systems, while Air France and KLM reported a data breach in their customer service platform.
The surge in attacks underscores the growing sophistication of threat actors and the widespread impact of ransomware on global operations.
