Japan Airlines: DDoS attack delays 71 flights

On 26 December 2024 Japan Airlines said a network device connecting its internal and external networks failed from 7:24 a.m., disrupting systems that talk to outside systems. The failure was caused by a large volume of incoming data; no customer data leaked and there was no malware damage. It paused ticket sales for same-day flights, and automated bag drops, its app and other services were affected. 60 domestic and 11 international flights were delayed by 30 minutes or more (up to 4 hours 2 minutes), and 4 flights were cancelled. It cut off the device and recovered shortly after 1 p.m. the same day.
