function Invoke-ReflectivePEInjection
{
<#
.SYNOPSIS
The script is mostly copied from the PowerSploit Invoke-ReflectivePEnjection module written by Joe Bialek.
The script injects simple msgbox dll into given processs.
.DESCRIPTION
Reflectively loads a MsgBox dll in to a remote process.
.PARAMETER ComputerName
Optional, an array of computernames to run the script on.
.PARAMETER FuncReturnType
Optional, the return type of the function being called in the DLL. Default: Void
Options: String, WString, Void. See notes for more information.
IMPORTANT: For DLLs being loaded remotely, only Void is supported.
.PARAMETER ExeArgs
Optional, arguments to pass to the executable being reflectively loaded.
.PARAMETER ProcName
Optional, the name of the remote process to inject the DLL in to. If not injecting in to remote process, ignore this.
.PARAMETER ProcId
Optional, the process ID of the remote process to inject the DLL in to. If not injecting in to remote process, ignore this.
.PARAMETER ForceASLR
Optional, will force the use of ASLR on the PE being loaded even if the PE indicates it doesn't support ASLR. Some PE's will work with ASLR even
if the compiler flags don't indicate they support it. Other PE's will simply crash. Make sure to test this prior to using. Has no effect when
loading in to a remote process.
.PARAMETER DoNotZeroMZ
Optional, will not wipe the MZ from the first two bytes of the PE. This is to be used primarily for testing purposes and to enable loading the same PE with Invoke-ReflectivePEInjection more than once.
.EXAMPLE
Refectively the msgbox dll in to the lsass process on a remote computer.
