Japan - December 27, 2024 Japan’s flag carrier announced that it has restored its systems following a cyber incident that delayed some domestic and international flights on Thursday. Japan Airlines (JAL) stated that a “system malfunction” occurred due to a sudden surge in traffic on its network equipment used for data communication with external systems. Such attacks, known as distributed denial-of-service (DDoS) attacks, disrupt the normal operation of a website or server by overwhelming it with a flood of traffic from multiple sources. Upon identifying the issue, the carrier said it temporarily shut down the affected system and suspended ticket sales for same-day departures, along with some online services for passengers. According to local media reports, the attack also impacted the system for managing passenger baggage, as well as the company’s mobile app.
