Sapporo transit system intrusion triggers false service alerts
Impact: False service alerts sent and transit information app and web services temporarily suspended
Unauthorized external access to the service information distribution system of Sapporo Ekibus Navi, Sapporo’s public transit information service, resulted in false alerts about subway 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 transit actually operated normally.
