Memutuskan koneksi Wifi Orang Lain dengan Backtrack

Perhatikan langkah saya dalam memutuskan jaringan wifi orang lain menggunakan Backtrack

1. Buka terminal lalu ketikkan ifconfig untuk memeriksa interface anda
    wlan0 adalah nama default pada Backtrack.
    

2. Aktifkan mode monitor dengan perintah :

     airmon-ng start wlan0
 

3. Mode monitor aktif. Untuk scanning korban, masukkan perintah :

     airodump-ng mon0

    ctrl+C untuk menghentikan scanning. Tentukan target (Ex:70:f1:a1:b2:72:77)
    

4.Langkah memutuskan jaringan korban, masukkan perintah berikut

     aireplay-ng -0 jumlahpaket -a BSSID -c Macadresskorban mon0

    Jumlah paket : lamanya pemutusan jaringan tergantung banyaknya pket
    untuk BSSID

    Contoh : (aireplay-ng -0 500 -a 11:22:33:44:55:66 -c 70:f1:a1:b2:72:77 mon0)

How To Hack WPA/WPA2 Wi-Fi With Kali Linux & Aircrack-ng

          Kali Linux can be used for many things, but it probably is best known for its “ability” to hack WPA and WPA2. There are hundreds of tools for windows that claim they can hack into WPA; don’t get them! They’re just scams. There is only one real way to hack into a WPA network, and that is with a Linux-based OS, a wireless card capable of monitor mode, and aircrack-ng. Also note that, even with these tools, Wi-Fi cracking is not for beginners. Hacking it requires basic knowledge of how WPA authentication works, and moderate familiarity with Kali Linux and its tools. These are things that you’ll need:

• A successful install of Kali Linux (which you probably already have done). If not, follow my tutorial here: http://j.gs/3tUb
• A wireless adapter capable of injection/monitor mode, here is a list of the best: http://blackmoreops.com/recommended-usb-wireless-cards-kali-linux
• A wordlist to crack the handshake password once it has been captured
• Time and patients

If you have these then roll up your sleeves and let’s get to it.
          Important notice: Hacking into anyone’s Wi-Fi without permission is considered an illegal act or crime in most countries. We are performing this tutorial for the sake of penetration testing, and are hacking into our own test router to do so.

By reading and/or using the information below, you are agreeing to
our Disclaimer, which can be found here: http://lewiscomputerhowto.blogspot.com/disclaimor.html

---

Step One:

Start Kali Linux and login, preferably as root.

Step Two:
Plugin your injection-capable wireless adapter, (Unless your computer card supports it). If you’re using Kali in VMware, then you might have to connect the card via the icon in the device menu.
Step Three:
Disconnect from all wireless networks, open a Terminal, and type airmon-ng

This will list all of the wireless cards that support monitor (not injection) mode. If no cards are listed, try disconnecting and reconnecting the card and check that it supports monitor mode. You can check if the card supports monitor mode by typing ifconfig in another terminal, if the card is listed in ifconfig, but doesn’t show up in airmon-ng, then the card doesn’t support it.
You can see here that my card supports monitor mode and that it’s listed as wlan0.
Step Four:
Type airmon-ng start followed by the interface of your wireless card. mine is wlan0, so my command would be: airmon-ng start wlan0

The “(monitor mode enabled)” message means that the card has successfully been put into monitor mode. Note the name of the new monitor interface, mine is mon0.
Step Five:
Type airodump-ng followed by the name of the new monitor interface, which is probably mon0.

Step Six:
Airodump will now list all of the wireless networks in your area, and lots of useful information about them. Locate your network or the network that you have permission to penetration test. Once you’ve spotted your network on the ever-populating list, hit Ctrl + C on your keyboard to stop the process. Note the channel of your target network.

Step Seven:
Copy the BSSID of the target network

Now type this command:
airodump-ng –c [channel] –bssid [bssid] –w /root/Desktop/ [monitor interface]Replace [channel] with the channel of your target network. Paste the network BSSID where [bssid] is, and replace [monitor interface] with the name of your monitor-enabled interface, (mon0).

A complete command should look like this:
airodump-ng -c 10 --bssid 00:14:BF:E0:E8:D5 -w /root/Desktop/ mon0

Now press enter.
Step Eight:
Airodump with now monitor only the target network, allowing us to capture more specific information about it. What we’re really doing now is waiting for a device to connect or reconnect to the network, forcing the router to send out the four-way handshake that we need to capture in order to crack the password.
Also, four files should show up on your desktop, this is where the handshake will be saved when captured, so don’t delete them!
But we’re not really going to wait for a device to connect, no, that would take too long. We’re actually going to use another cool-tool that belongs to the aircrack suite called aireplay-ng, to speed up the process. Instead of waiting for a device to connect, we’re going to use this tool to force a device to reconnect by sending deauthentication (deauth) packets to the device, making it think that it has to reconnect with the router.
Of course, in order for this tool to work, there has to be someone else connected to the network first, so watch the airodump-ng and wait for a client to show up. It might take a long time, or it might only take a second before the first one shows. If none show up after a lengthy wait, then the network might be empty right now, or you’re to far away from the network.

You can see in this picture, that a client has appeared on our network, allowing us to start the next step.

Step Nine:
leave airodump-ng running and open a second terminal. In this terminal, type this command:
aireplay-ng –0 2 –a [router bssid] –c [client bssid] mon0The –0 is a short cut for the deauth mode and the 2 is the number of deauth packets to send.
-a indicates the access point (router)’s bssid, replace [router bssid] with the BSSID of the target network, which in my case, is 00:14:BF:E0:E8:D5.
-c indicates the clients BSSID, noted in the previous picture. Replace the [client bssid] with the BSSID of the connected client, this will be listed under “STATION.”
And of course, mon0 merely means the monitor interface, change it if yours is different.
My complete command looks like this:
aireplay-ng –0 2 –a 00:14:BF:E0:E8:D5 –c 4C:EB:42:59:DE:31 mon0

Step Ten:
Upon hitting Enter, you’ll see aireplay-ng send the packets, and within moments, you should see this message appear on the airodump-ng screen!


This means that the handshake has been captured! You can close the aireplay-ng terminal and hit Ctrl + C on the airodump-ng terminal to stop monitoring the network, but don’t close it yet just incase you need some of the information later.
Step 11:
This concludes the external part of this tutorial. From now on, the process is entirely between your computer, and those four files on your Desktop. Actually, the .cap one, that is important. Open a new Terminal, and type in this command:
aircrack-ng -a2 -b [router bssid] -w [path to wordlist] /root/Desktop/*.cap
-a is the method aircrack will use to crack the handshake, 2=WPA method.
-b stands for bssid, replace [router bssid] with the BSSID of the target router, mine is 00:14:BF:E0:E8:D5.
-w stands for wordlist, replace [path to wordlist] with the path to a wordlist that you have downloaded. I have a wordlist called “wpa.txt” in the root folder.
/root/Desktop/*.cap is the path to the .cap file containing the password, the * means wild card in Linux, and since I’m assuming that there are no other .cap files on your Desktop, this should work fine the way it is.
My complete command looks like this:
aircrack-ng –a2 –b 00:14:BF:E0:E8:D5 –w /root/wpa.txt  /root/Desktop/*.cap

Now press Enter.
Step 12:
Aircrack-ng will now launch into the process of cracking the password. However, it will only crack it if the password happens to be in the wordlist that you’ve selected. Sometimes, it’s not. If this is the case, then you can congratulate the owner on being “Impenetrable,” of course, only after you’ve tried every wordlist on the internet!
Cracking the password might take a long time depending on the size of the wordlist. Mine went very quickly.
If the phrase is in the wordlist, then aircrack-ng will show it too you like this:


The passphrase to our test-network was notsecure, and you can see here that aircrack found it!
If you see a message similar to this, then your tests have penetrated the network. Tell the owner that he needs a stronger password!

Mematikan Koneksi Menggunakan MDK3 Di Backtrack

Pada umumnya pemutusan koneksi dari client to client biasanya dilakukan dengan menggunakan netcut, hal itu biasanya sering kita temukan pada pengguna windows. Jika pada pengguna linux, kita sering menemukan yang fungsinya tidak jauh berbeda dengan netcut tersebut. Seperti Tuxcut, arpspoof serta mdk3, tetapi dalam hal ini saya lebih tertarik menggunakan mdk3 dikarenakan bukan hanya membunuh koneksi client yang di sekitar hotspot, bahkan juga memutuskan koneksi yang berada dalam satu lingkungan Access Point pada sebuah hotspot, atau warnet. Tipe penyerangan dari mdk3 menggunakan titik fokus pada Media Access Control (MAC) Address. Bahaya bukan, baiklah kita akan membahas bagaimana caranya untuk menggunakan hal ini. Meski diketahui juga mdk3 juga telah tersedia didalam distro backtrack. Mari kita lanjut ke pembahasan dibawah ini, dengan cara-caranya langsung.

• Aktifkan monitoring interface anda dengan cara 

• lihat mac address anda dengan cara "ifconfig wlan0" (interface tergantung dari yang anda miliki) hal ini dilakukan agar koneksi anda tidak menjadi senjata makan tuan. Copy paste mac address kemudian masukkan mac tersebut dengan cara "echo FF:FF:FF:FF:FF:FF >> whitelist.txt (berarti mac address anda disimpan di file whitelist.txt)"

• Kemudian saatnya untuk mematikan seluruh koneksi yang berada dalam AP yang anda inginkan (semua AP yang terdeteksi akan turut DC alias Disconnect semua client-clientnya), caranya yaitu seperti gambar ini.

 

Jika anda merasa iba dengan koneksi teman anda sendiri, alias ingin dia terkoneksi juga seperti anda lakukan perintah berikut. Seperti tadi, berarti anda harus memasukkan juga mac address teman anda tetapi caranya sedikit berbeda untuk eksekusinya serta file dimana untuk menyimpan mac. Jika anda kurang mengerti, akan saya jelaskan. Untuk whitelist.txt itu adalah single mac address, jadi cuman mac address anda saja artinya cuman anda saja yang terkoneksi. Jika untuk gambar dibawah ini file blacklist.txt adalah untuk banyak dua atau lebih mac address, termasuk mac address anda. mac address yang anda masukkan di blacklist.txt tersebut yang akan terkoneksi. Mengertikan ?

Ingat kalimat saya diatas, mdk3 mematikan AP yang terdeteksi oleh komputer kita. Jika anda menginginkan satu AP saja yang anda isengi, maka lakukan perintah berikut ini

• mdk3 mon0 d -c channel_ap_target -w whitelist.txt 
• mdk3 mon0 d -c channel_ap_target -b blacklist
• mdk3 mon0 a -t FF:FF:FF:FF:FF:FF (Perintah ini untuk mem-flooding AP yang terenkripsi)
• mdk3 mon0 g -t FF:FF:FF:FF:FF:FF (Perintah ini untuk meng-deauth AP yang terenkripsi)
