TOKYO, Dec. 26 (Xinhua) — Japan Airlines (JAL) said Thursday that its network system has been restored after a cyberattack earlier in the day disrupted luggage services and delayed some flights.
JAL said tickets sales for both domestic and international flights have now been resumed after a temporary halt, adding that no personal information was leaked and no damage was caused by computer viruses.
The network disruption occurred at 7:24 a.m. local time, causing problems with baggage check-ins and delays for a dozen flights at several Japanese airports, the airline said.
At 8:56 a.m. local time, JAL blocked the data transmission device that was causing the system failure, it added.
JAL told police that it may have been the victim of a distributed denial-of-service, or DDoS attack, in which networks are overwhelmed by massive amounts of data from multiple sources over a short period, according to investigative sources.
The company said it was working to counteract the cyberattack and determine its source. ■
