Auditing authentication-system traffic records for 25 October revealed intrusion traces. MNS account names, IDs, passwords and email may have leaked; the count and password-storage format are undisclosed. The university says jindai.jp passwords were not exposed. [1]

External communications were blocked, stopping off-campus MNS mail, VPN, WeBSt@tion, MNS Web Mail and other shared-authentication services. The teacher attendance-management screen is also unavailable on campus, while student-card attendance recording continues. Authentication-system replacement is planned during November, preceded by a system-wide password reset. [1]
