Sapporo transport system intrusion triggers false service alerts

First reported · Last reported · 15 related reports

Unauthorised external access to the service information distribution system of Sapporo Ekibus Navi, Sapporo’s public transport information service, resulted in false alerts about underground service suspensions and delays on all lines being sent through the app and the official LINE account. The city temporarily suspended the app and web services to verify their security. The system held no personal information, so no personal information was leaked, and public transport actually operated normally.
