Executive Summary
A significant cyberattack targeted Japan Airlines (JAL) on December 26, 2024, resulting in the temporary suspension of ticket sales and delays for 24 domestic flights. The incident, occurring during a busy holiday season, involved a Distributed Denial of Service (DDoS) attack that overwhelmed the network systems connecting internal and external operations. Fortunately, no customer data was compromised, and flight safety remained unaffected. The attack highlights vulnerabilities in Japan's cybersecurity infrastructure, raising concerns as the nation strengthens its defense capabilities and international collaborations. Immediate implications include operational disruptions and customer inconvenience, while long-term effects may involve increased cybersecurity investments and policy adjustments. Industry-wide, the incident underscores the need for robust cyber defenses in the aviation sector.
Incident Overview
On December 26, 2024, Japan Airlines (JAL) experienced a cyberattack that disrupted its network systems. The attack began on Thursday morning and was resolved within hours on the same day. The primary impact was the delay of 24 domestic flights and the temporary suspension of ticket sales for both domestic and international flights.

Related Events
In June 2023, Japan's space agency reported a series of cyberattacks, although sensitive information related to rockets, satellites, and defense was not affected. Additionally, a cyberattack last year paralyzed operations at a container terminal in Nagoya for three days, highlighting ongoing cybersecurity challenges in Japan.
Recommendations
Critical: Implement multi-factor authentication across all remote access systems to enhance security against unauthorized access.
High: Conduct regular network stress testing to identify and mitigate vulnerabilities to DDoS attacks.
Medium: Increase cybersecurity awareness and training for staff to recognize and respond to potential threats.
Low: Review and update incident response plans to ensure timely and effective management of future cyber incidents.
