function Invoke-PsExec
{
<#
.SYNOPSIS
Invoke-SMBExec performs SMBExec style command execution with NTLMv2 pass the hash authentication. Invoke-SMBExec
supports SMB1 and SMB2 with and without SMB signing.
.PARAMETER Target
Hostname or IP address of target.
.PARAMETER Username
Username to use for authentication.
.PARAMETER Domain
Domain to use for authentication. This parameter is not needed with local accounts or when using @domain after the
username.
.PARAMETER Hash
NTLM password hash for authentication. This module will accept either LM:NTLM or NTLM format.
.PARAMETER Command
Command to execute on the target. If a command is not specified, the function will check to see if the username
and hash provides local administrator access on the target.
.PARAMETER CommandCOMSPEC
Default = Enabled: Prepend %COMSPEC% /C to Command.
.PARAMETER Service
Default = 20 Character Random: Name of the service to create and delete on the target.
.PARAMETER SMB1
(Switch) Force SMB1. The default behavior is to perform SMB version negotiation and use SMB2 if supported by the
target.
.PARAMETER Sleep
Default = 150 Milliseconds: Sets the function's Start-Sleep values in milliseconds. You can try tweaking this
setting if you are experiencing strange results.
.EXAMPLE
Invoke-SMBExec -Target 192.168.100.20 -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Command "command or launcher to execute" -verbose
.EXAMPLE
Invoke-SMBExec -Target 192.168.100.20 -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Command "net user SMBExec Winter2017 /add"
.EXAMPLE
Invoke-SMBExec -Target 192.168.100.20 -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0

<#
.SYNOPSIS
This cmdlet returns the MD4 hash of the data that is input.
WARNING: MD4 is not secure, so it should NEVER be used to
protect sensitive data. This cmdlet is for research purposes only!
.DESCRIPTION
This cmdlet returns the MD4 hash of the data that is input.
WARNING: MD4 is not secure, so it should NEVER be used to
protect sensitive data. This cmdlet is for research purposes only!
This cmdlet uses Microsoft's implementation of MD4, exported
from bcrypt.dll. The implementation is fully compliant with
RFC 1320. This cmdlet takes a byte array as input, not a string.
So if you wanted to hash a string (such as a password,) you
need to convert it to a byte array first.
.EXAMPLE
Get-MD4Hash -DataToHash $([Text.Encoding]::Unicode.GetBytes("YourPassword1!"))
.PARAMETER DataToHash
A byte array that represents the data that you want to hash.
.INPUTS
A byte array containing the data you wish to hash.
.OUTPUTS
A 128-bit hexadecimal string - the MD4 hash of your data.
