Writing your own Metasploit module

As mentioned earlier, a white hat hacker should know how to write their own tools and scripts. So, let's see how to create a simple Metasploit module. In this demonstration, we'll use Ruby as a programming language, and we'll build a TCP scanner.

First, create a Ruby file:

require 'msf/core'
class Metasploit3 <Msf::Auxiliary
include Msf::Exploit::Remote::Tcp
include Msf::Auxiliary::Scanner
def intialize
super(
'Name' => 'TCP scanner',
'Version' => '$Revisiov: 1 $',
'Description' => 'This is a Demo for Packt Readers',
'License' => MSF_LICENSSE
)
register_options([
opt::RPORT(3000)
], self.class)
end
def run_host(ip)
connect()
greeting = "Hello Cybrary"
sock.puts(greeting)
data = sock.recv(1024)
print_status("Received: #{data} from #{ip}"...
