Powershell Empire  and Starkiller  is another incredibly popular C2 originally created by Harmjoy, Sixdub, and Enigma0x3 from Veris Group. Currently, the project has been discontinued and has been picked up by the BC Security team (Cx01N, Hubbl3, and _Vinnybod). Empire features agents written in various languages compatible with multiple platforms, making it an incredibly versatile C2.
