False alerts and suspended services
At about 06:35 and 12:10 on 9 November, external unauthorized access to Eki Bus Navi’s distribution system resulted in false transit information. At about 12:40, the city stopped Eki Bus Navi and part of the transportation website, including status updates on its homepage, to prevent confusion and verify safety. [1]
Personal-data exposure is not confirmed. Services will reopen after safety checks; urgent updates use station displays and official city social accounts meanwhile. The notice concerns information services, not a confirmed compromise of trains or operational control systems. [1]
