Japan Airlines (JAL) has announced that its systems have returned to normal following a cyberattack that had previously disrupted its flight operations, causing delays across both domestic and international flights. The incident, which unfolded on December 25, 2024, was a stark reminder of the vulnerabilities airlines face in an increasingly digital landscape.

The cyberattack commenced early on Thursday morning, affecting JAL's network equipment responsible for communicating with external systems. This led to significant operational hiccups, particularly with the airline's baggage handling and check-in processes. The attack was identified around 7:24 AM local time, prompting JAL to temporarily shut down a problematic router to contain the spread of the malfunction. This action, while necessary, contributed to the suspension of ticket sales for flights departing that day. By the evening of December 25, JAL reported that the cause of the disruption had been identified and the system was restored. The airline confirmed that no personal customer data was compromised during the cyberattack, alleviating concerns over data privacy. The attack was described by JAL as a "large data attack," potentially a Distributed Denial of Service (DDoS) aimed at overwhelming the airline's network with excessive data traffic.
This cyber incident led to the delay of over 24 domestic flights, with some delays exceeding 30 minutes. Although the impact was relatively contained, considering the scale of JAL's operations, the timing could not have been worse, coinciding with Japan's peak of the New Year holiday travel season. The airline managed to resume ticket sales and operations for same-day flights by the end of the day, but the initial disruption left many passengers scrambling to adjust their travel plans. The quick response by JAL's IT and cybersecurity teams, alongside cooperation with external experts, was crucial in mitigating the attack's impact. The airline has since been investigating the breach to enhance its cybersecurity measures, aiming to prevent future incidents. JAL emphasized its commitment to safety, stating that while the cyberattack did not compromise flight safety, it was a significant inconvenience to passengers.
The Transport Ministry, led by Chief Cabinet Secretary Yoshimasa Hayashi, directed JAL to expedite the system's restoration and ensure that affected passengers were properly accommodated. This event highlights the broader issue of cyber threats to critical infrastructure like aviation. JAL is just the latest in a series of Japanese companies targeted by cybercriminals, following attacks on companies like JAXA (Japan Aerospace Exploration Agency) and various ports, which had previously been hit by ransomware and other forms of cyberattacks. Japan Airlines has issued an apology for the inconvenience caused and is offering compensation in the form of mileage points or other gestures to affected passengers. The airline reassured travelers that it is working to strengthen its cyber defenses to maintain the integrity and reliability of its services. This incident serves as a reminder of the continuous need for vigilance in cybersecurity, particularly for industries where operational continuity is paramount.
