Invoke-SMBExec +supports SMB1 and SMB2 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 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. + +.PARAMETER Session +Inveigh-Relay authenticated session. + +.PARAMETER SigningCheck +(Switch) Checks to see if SMB signing is required on a target. + +.EXAMPLE +Execute a command. +Invoke-SMBExec -Target 192.168.100.20 -Domain TESTDOMAIN -Username TEST -Hash F6F38B793DB6A94BA04A52F1D3EE92F0 -Command "command or
