Hello @Cosm1c
Not an expert in security myself, but it seems that it is in MS database of hacktools: https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=HackTool:Win32/SolarFlare.A!dha&ThreatID=2147771376
Regarding the information about signatures specifics or payload information Microsoft has been always secretive, as most of security companies, to avoid providing information that would help hackers to bend the code to bypass them.
Hope this helps with your query,
