🚨 Nihon Kotsu, Japan's largest taxi and chauffeur operator, has shut down parts of its IT infrastructure after detecting unauthorized external access and a malware infection early Saturday. The outage has affected the taxi dispatch system, web booking, reservation management, phone dispatch services, and some internal systems, leaving key services offline while the company investigates.
