This program reveals the details of the massive 2.9TB data breach at Nihon Kotsu, Japan's largest taxi company, and the underlying security management challenges.

Featuring Takayuki Sugiura of the Japan Hacker Association as a guest, the program delves into the truth behind the incident based on a file list exceeding 390,000 lines leaked onto the dark web and OSINT investigations.

The program examines the lax operational system, including the management of driver's licenses, SQL backups, customer destination data, and even dashcam passwords in text files.

Furthermore, it considers lessons learned from the VPN vulnerabilities that emerged as entry points, the risk of user account leaks, and the importance of crisis management and information disclosure required of companies.

*While Nihon Kotsu's operations are still running as normal at the time of recording, some services, such as the "Labor Taxi," have temporarily suspended new registrations.
