Abstract: Largescale sports events have become important targets for cyber attacks due to their large scale, wide coverage, strong influence, and high level of informatization. Cyber attacks on sports events exhibit characteristics such as precise attack targets, industrialization of attack teams, and massive attack scale.Based on the characteristics of largescale sports event informatization business, this article takes information systems, venues, user groups, and supply chains as attack surfaces, analyzes the motivations, targets, types, capabilities, and other characteristics of cyber attacks, and combines sports events and cyber attack motivations, targets, and methods to construct threat scenarios. Targeted prematch, duringgame, and postgame support strategies are proposed to effectively prevent and prevent cyber attacks. Which is of great significance to all parties involved in the event.
