IDCF Cloud ransomware attack hits 495 Japanese customers
IDC Frontier, a large Japanese cloud and digital infrastructure provider, has confirmed that a ransomware attack knocked out part of its IDCF Cloud service. The outage hit a data center cluster serving eastern Japan, and the company says 495 companies and local governments use the affected service.
The attack began on October 7 at 3:40 AM local time. IDC Frontier responded by shutting down the network and systems involved.
"Our investigation has determined that a disruption in East Japan Region 1 was caused by a ransomware attack by a third party," the company said in its announcement. It added that it is "continuing to investigate the precise cause and the scope of the impact."
