Ransomware Takes Down IDCF Cloud Region in Japan — 495 Organizations Offline, Data May Be Unrecoverable

IDC Frontier, the SoftBank-owned data center and cloud operator, disclosed on October 7, 2026 that unauthorized third-party access began at roughly 3:40 a.m. Japan time in part of its IDCF Cloud service.
