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. -
