Osaka Metropolitan University shut down much of its IT environment and canceled classes after a suspected ransomware attack disrupted email, internal networks, and administrative systems. The university said about 500 servers stopped operating, with impacts across academic administration, payroll, HR, finance, library services, and websites. Japanese media reported that data tied to at least 130,000 current and former students, staff, and related individuals may have been exposed, though OMU said it has not yet confirmed data theft.
Why it matters: This is a major disruption at one of Japan’s largest universities, affecting teaching and core business systems while raising possible data-exposure risks for students and staff. People connected to the university should watch for official breach notices and phishing, while peer institutions should review ransomware resilience, segmentation, and backup recovery plans.
