TOKYO, Apr 08 (Pulse News Wire) – Sumitomo Metal Mining CO.,LTD. (5713.T) reported a cyber attack on Coral Bay Nickel Corporation (CBNC), its nickel refining subsidiary based in Palawan, Philippines.
On April 2, two CBNC servers were detected to be encrypted due to suspected ransomware infection, leading to immediate isolation measures. External experts are assisting with investigations and recovery efforts. The incident has affected network communications within CBNC and partially shared networks with Sumitomo Metal Mining Philippine Holdings Corporation and Taganito HPAL Nickel Corporation.
Operations at CBNC's production plant remain unaffected, and there is no impact on production activities at other group facilities. However, network disruptions have been implemented to secure operations. Regarding the potential impact on the group’s fiscal year 2026 March quarter earnings, the company believes the effects are currently minor but is still assessing the situation, including possible delays in financial reporting.
