Japan's Keio confirms ransomware attack disrupted business systems

Keio Corporation, a major private railway operator in Japan, disclosed that a ransomware attack over the weekend of September 27-28 disrupted some of its business systems. The incident affected the company's network infrastructure and operational capabilities.

Why it matters: Transportation operators and their customers face service disruptions and data exposure risks; practitioners should assess whether critical infrastructure dependencies are backed by ransomware response and recovery plans.
