Basic Usage

There are two ways to execute this post module.

From the msf prompt

The second is by using the "use" command at the msf prompt. You will have to figure out which session ID to set manually. To list all session IDs, you can use the "sessions" command.

msf > use post/windows/manage/powershell/load_script
msf post(load_script) > show options
    ... show and set options ...
msf post(load_script) > set SESSION session-id
msf post(load_script) > exploit

If you wish to run the post against all sessions from framework, here is how:

1 - Create the following resource script:


framework.sessions.each_pair do |sid, session|
  run_single("use post/windows/manage/powershell/load_script")
  run_single("set SESSION #{sid}")
  run_single("run")
end

2 - At the msf prompt, execute the above resource script:

msf > resource path-to-resource-script
