National Security Council staff has stood up Cyber Unified Coordination Group (UCG), composed of the FBI, CISA, and ODNI with support from NSA, to coordinate the investigation and remediation of this significant cyber incident involving federal government networks. The UCG believes that, of the approximately 18,000 affected public and private sector customers of Solar Winds Orion product, a much smaller number have been compromised by follow-on activity on their systems. CISA issued a technical alert providing technical details and mitigation strategies to help network defenders take immediate action.”]
