Hack a wifi network easily . Real and working .
Guys Here is a quick tutorial of cracking any wireless network. I tried to make it user friendly. If you think it's a lil complex to understand, goto the link mentioned at the bottom for Pictorial Tut.
Requirement:
A PC installed with Linux Backtrack 5 RC2
Working Wireless LAN Card Installed (Important Part)
Huge Updated Dictionary File with password (Google It)
Goto any wifi hotspot, and crack it..
Let's start
Step 1:
Run this command to check available Wlan adapters.
airmon-ng
It should give you output something. Means it'll show us wlan networks.
Now we know that we have only one wireless interface wlan0.
Step 2:
Now lets try to start the airmon service on the interface that we have just found in Step 1. Run the give command
Ignore the errors mentioned above in my case it did not create any trouble for me but you might want to kill the conflicting services if results are different then mine. By second step we have started the service/monitor on WLAN0 now we should have additional monitoring interface on the system. You can check if a new interface mon0 is added on your system or not by using command ifconfig else try the step 3
Step 3:
You should see another monitoring interface mon0 on your system by using command ifconfig or you can the same command we did on Step 1
Here we can see the new monitoring interface mon0
Step 4:
A good hacker is always suppose to leave no trace back of his break-in.If you run the command ifconfig and notice you will find that the monitoring interface mon0 and Wireless interface Wlan0 are sharing the same MAC address. In actual mon0 is sharing the same mac address as Wlan0. check the pic below
Now we have to put a fake mac address on the monitoring interface to leave no trace.Lets make the mon0 interface down by running the command
ifconfig mon0 down
Next lets change the MAC address of mon0 interface by running the below command
The output actually shows the old and new Fake mac address.Now since we have changed the MAC address on MON0 lets bring the interface back up again using the below command
Now just to be sure lets run the same command ‘ifconfig’ that we have already used earlier above in Step 4
Here we can see we have sucessfully changed the MAC address for our monitoring interface mon0
Step 5:
Lets start du*ping the available wireless information. run the below command
Note: Replace "*" with "m" in the code wherever you see, this is altered to make the post safe, otherwise it'll be a spam.
Here my Victim router ESSID is AndroidHotSpot. The information that I need from here is
BSSID MAC details: D0:C1: B1:5B:AC:33
CHANNEL: 6
Step 6:
By now we have identified our victim its time to further narrow down this network. We need to know how many workstation/terminal connected to this wireless. Run this command with your network information that you obtained in Step 5:
Here I can see that one client having mac address highlighed in green is connected to this hotspot. To find the password either you need to be patient to wait another client connect to this hotspot but time is money lets force this client to reconnect and make the handshake auth with the server so that we can take the packets
Note: Keep this ssh session close and open another terminal for Step 7. Do not close the existing session
Step 7:
Lets force the already connected session to make a auth handshake again
Run the given below command in the new terminal session
Final Step:
Now finally we have all the dumbed saved in the working directory we just need to crack the packet capture using dictionary file. Run the below command
** crackwpa-01.cap is the filename of the capture packet
** list if the my dictionary file name
That's all... Finally you'll have key of the Network..

Code:
ifconfig mon0 up
Code:
ifconfigHere we can see we have sucessfully changed the MAC address for our monitoring interface mon0
Step 5:
