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/multi/gather/dns_reverse_lookup

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

  • RHOSTS: IP Range to perform reverse lookup against.
