Tokyo, Japan – Japan Airlines (JAL) announced on Thursday that its network systems have been restored following a cyberattack earlier in the day that disrupted baggage services and delayed several flights.

The airline stated that ticket sales for both domestic and international flights have resumed after a temporary halt. JAL also confirmed that no personal information was leaked and that no computer viruses caused any damage.

The system disruption occurred at 7:24 AM local time, causing issues with baggage check-in and delays to a dozen flights at various Japanese airports.

At 8:56 AM local time, JAL blocked the data transmission device that was causing the system failure.

JAL reported to the police that they may have been the victim of a distributed denial-of-service (DDoS) attack, where networks are overwhelmed by massive amounts of data from multiple sources over a short period.

The company assured the public that it was working to counteract the cyberattack and determine its origin.
