On Thursday, Japan Airlines (JAL) disclosed that a cyber attack targeted its internal and external network systems, disrupting passenger baggage management and other operations.
The airline confirmed that the system was restored shortly after 1 p.m., roughly six hours after the initial disruption. JAL stated that there was no evidence that customer data had been compromised.
The cyber attack impacted the system for communicating flight plans to Japan’s Ministry of Land, Infrastructure, Transport and Tourism. Check-in procedures and baggage management systems were also temporarily suspended. The system failure additionally caused intermittent access issues to JAL’s Apple application.
As a result, 71 domestic and international flights experienced delays exceeding 30 minutes. Four domestic flights were canceled outright, and JAL also announced the cancellation of one domestic flight scheduled for Friday.
Local law enforcement agencies are investigating the possibility of a Distributed denial-of-service (DDoS) attack on the airline.
In a public statement, JAL apologized sincerely for the inconvenience caused to passengers and all affected parties.
