SolarWinds.Orion.Core.BusinessLayer.dll is a SolarWinds digitally-signed component of the Orion software framework that contains a backdoor that communicates via HTTP to third party servers. We are tracking the trojanized version of this SolarWinds Orion plug-in as SUNBURST.
This is further proof that digitally signed software alone is insufficient to determine trustworthiness and that a comprehensive software supply chain risk assessment, that includes a malware scan, is needed to identify software supply chain risk. Energy Central hosted a Powersession on 8/12/2020 describing best practices for software supply chain risk assessments, based on the NIST Cybersecurity Framework, V1.1.
