function global:Invoke-ExecBySMB
{
<#
.SYNOPSIS
Invoke-SMBExec performs SMBExec style command execution with NTLMv2 pass the hash authentication. Invoke-SMBExec
supports SMB1 and SMB2.1 with and without SMB signing.
Author: Kevin Robertson (@kevin_robertson)
License: BSD 3-Clause
.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 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.
.PARAMETER Session
Inveigh-Relay authenticated session.
.PARAMETER Version
Default = Auto: (Auto,1,2.1) Force SMB version. The default behavior is to perform SMB version negotiation and use SMB2.1 if supported by the
target.
.EXAMPLE
Execute a command.
Invoke-SMBExec -Target 192.168.100.20 -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Command "command or launcher to execute" -verbose
.EXAMPLE
Check command execution privilege.
Invoke-SMBExec -Target 192.168.100.20 -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0
.EXAMPLE
Execute a command using an authenticated Inveigh-Relay session.
Invoke-SMBExec -Session 1 -Command "command or launcher to execute"
.EXAMPLE
Check if SMB signing is required.
Invoke-SMBExec -Target 192.168.100.20
