Hack wireless Network using AIRCRACK-NG

Find out the name of your wireless adapter.


1. First there are basically the following things that you need to know
2. lo - loopback. Not important currently.
3. eth - ethernet
4. wlan - This is what we want. Note the suffix associated.
Now, to see all the adapters, type ifconfig on a terminal. See the result. Note down the wlan(0/1/2) adapter
*Enable Monitor mode

5. Now, we use a tool called airmon-ng to create a virtual interface called mon.
6. Just type airmon-ng start wlan0 Your monitoring interface will be created - mon0 in case of Kali 1.x, wlan0mon in all other cases.
*Start capturing packets

7. Now, we'll use airodump-ng to capture the packets in the air. This tool gathers data from the wireless packets in the air. You'll see the name of the wifi you want to hack. For kali 2.0 or rolling, replace mon0 with wlan0mon airodump-ng mon0
*Store the captured packets in a file

8. This can be achieved by giving some more parameters with the airodump command. For Kali 2.0 or rolling, replace mon0 with wlan0mon. *airodump-ng mon0 --write name_of_file
Now the captured packets will be stored in name_of_file.cap You will have to wait till you have enough data (10000 minimum)

9. Crack the wifi Now, you can use aircrack-ng to crack the password. 
10. (in a new terminal) aircrack-ng name_of_file-01.cap The program will ask which wifi to crack, if there are multiple available.
11. Choose the wifi. It'll do its job. If the password is weak enough, then you'll get it in front of you.
12. If not, the program will tell you to get more packets. The program will retry again when there are 15000 packets, and so on.
13. You'll get the key, probably in this format- xx:xx:xx:xx:xx Remove the colons xxxxxxxxxx is the password of the wireless network
