[Escalating Cyber Threats to Medical Institutions] In February 2026, a ransomware attack occurred at a university hospital in Japan via a maintenance VPN for medical equipment, resulting in the leakage of patient information for approximately 130,000 individuals. This incident, which also led to system failures and demands for a large ransom, highlights the urgent need for robust authentication infrastructure and continuous monitoring systems for medical information systems, including enhanced management of IDs and authentication information, as cyberattacks targeting medical institutions have become increasingly serious in recent years. Furthermore, the "Guidelines for Security Management of Medical Information Systems, Version 6.0" requires the introduction of two-factor authentication and the establishment of mechanisms for continuously verifying account security. However, implementing and operating these measures individually poses challenges in terms of operational burden and cost. This plan is designed to enable the implementation of the authentication enhancements and account monitoring required by such medical institutions with a simple configuration. This will support the strengthening of cybersecurity measures in medical institutions without compromising the convenience of daily operations.

[About the "GMO Trust Login Medical Institution Authentication Enhancement Plan"] This plan consists of the "SSO Pro Plan" and the "Password Leak Detection Option." The "SSO Pro Plan" provides advanced authentication functions necessary for medical institutions, such as desktop SSO with Windows integrated authentication, multi-factor authentication including one-time passwords and IP restrictions, and passwordless authentication compatible with biometrics (push/FIDO). In addition to the above, the "Password Leak Detection Option" automatically detects leaks of passwords used. With these two functions, medical staff can securely access multiple systems with a single ID and password input, balancing convenience and security.
