It is a modified DLL component of a legitimate software.\r\nAttackers use this threat to gain initial access to a device. When the related software is opened, this modified DLL\r\nis loaded and connects to command-and-control servers to listen for commands and get additional payloads.\r\nMicrosoft Defender Antivirus detects this threat. It raises an alert when it detects the threat on your device, but it\r\ndoesn't automatically remediate it in order to not affect legitimate services. If this threat is detected on your\r\nenvironment, we recommend that you immediately investigate and manually remediate it.\r\nNOTE: Microsoft continues to work with partners and customers to expand our knowledge of the threat actor\r\nbehind the nation-state cyberattacks that compromised the supply chain of SolarWinds and impacted multiple\r\nother organizations. Microsoft previously used ‘Solorigate’ as the primary designation for the actor, but moving\r\nforward, we want to place appropriate focus on the actors behind the sophisticated attacks, rather than one of the\r\nexamples of malware used by the actors. Microsoft Threat Intelligence Center (MSTIC) has named the actor\r\nbehind the attack against SolarWinds, the SUNBURST backdoor, TEARDROP malware, and related components\r\nas NOBELIUM. As we release new content and analysis, we will use NOBELIUM to refer to the actor and the\r\nattack campaigns.\r\nRead our latest reports: \r\nImportant steps for customers to protect themselves from recent nation-state cyberattacks\r\nCustomer Guidance on Recent Nation-State Cyber Attacks – Microsoft Security Response Center\r\nEnsuring customers are protected from Solorigate\r\nSource: https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Trojan:MSIL/Solorigate.B!dha\r\nhttps://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Trojan:MSIL/Solorigate.B!dha\r\nPage 1 of 1",
