REC Silicon – Cyber Security Incident

19 December 2022: REC Silicon ASA ("REC" or the "Company") has learned of a cyber security incident. The Company’s virtual server environment suffered a ransomware attack that caused business systems to stop functioning for a brief period of time. The Company engaged an incident response company that specializes in the recovery of data, restoration of systems, remediation, and investigation.

All systems of the Company have been successfully restored with only minor data loss. The Company’s production, safety, quality, sales, and revenue were not affected by the incident. Although all REC systems have been recovered, regretfully, the threat actor did exfiltrate a limited amount of data that does not appear to include any significant intellectual property of the Company. REC has implemented increased security and is taking additional steps to ensure the protection of its information and server environment from any future incidents.
