Ransomware Hits IDCF Cloud, Disrupts Japanese Govt Services

IDCF Cloud, a major Japanese cloud service provider, suffered a ransomware attack on October 7, causing an outage in its East Japan Region 1 data center. The attack impacted 495 companies and local governments using its infrastructure-as-a-service platform. The company isolated and shut down affected systems to prevent further spread and is investigating the breach’s cause and scope. The threat actor claims to have encrypted 225 databases and accessed numerous hypervisors and VM disks. Meanwhile, Japanese marine products company Nissui Corporation reported a system outage due to suspected unauthorized access to a third-party data center. The connection between the two incidents is unclear. Recent data shows a rise in cybersecurity incidents in Japan, with attackers exploiting known vulnerabilities and using AI tools to probe for weaknesses.
