C. Behavioral Summary
The AveMariaRat comes with a common technique that hide the exe malware using a fake Word icon, once launched the exe start some cmd that creates two distinct dll files.
nsExec.dll and System.dll saved in the temp folder C:\Users\<user>\AppData\Local\Temp\nsb436C.tmp (the last folder is a pseudo random name that change every time the malware is lauched). The an C:\Program Files (x86)\internet explorer\ieinstal.exe process is launched and probably injected with a shellcode using the Heaven’s Gate technique, this processc starts a connection with the C&C su1d.]nerdpol[.ovh with IP 4.236.162.205 on port 2222. Last the persistence, with the copy of the original malware in the local folder C:\Users\<user>\AppData\Local\Temp\Fadllers and the Demiparadise.exe name. More details are in the Static and Dynamic Analysis.
