Last stage of SmoothOperator payloads analyzed by Sentinel One (https://twitter.com/vxunderground/status/1641261800594210817). bf939c9c261d27ee7bb92325cc588624fca75429 is a PE loader that reads 20d554a80d759c50d6537dd7097fed84dd258b3e into memory, jumps to a shellcode that maps that dll file to memory and resolves its imports and then jumps to its single export, DllGetClassObject. This file is that mapped dll, with section sizes and addresses adjusted so it can be ran in a debugger.
