Hello friends as i heard many people are asking how to hack wifi..So im here to you to help to hack wifi Just follow the steps..
Here’s how to crack a WPA or WPA2
password, step by step, with Reaver and how
to protect your network against Reaver
attacks.
**NOTE :Consider this post educational, or a
proof of concept intellectual exercise. The
more you know, the better you can protect
yourself**
What You’ll Need
1.REAVER
2.A Blank DVD
3.A computer with compatible Wi-Fi
Here are the specific requirements for this
guide:
The BackTrack 5 Live DVD.
BackTrack is a bootable Linux distribution
that’s filled to the brim with network testing
tools, and while it’s not strictly required to
use Reaver, it’s the easiestapproach for
most users. Download the Live DVDfrom
BackTrack’s download pageand burn it to
aDVD.
You can alternately download a virtual
machine image if you’re using VMware, but if
you don’t know what VMware is, just stick
with the Live DVD.
You should select BackTrack 5 R3 from the
Release drop-down, select Gnome, 32- or
64-bit depending on your CPU , ISO for
image, and then download the ISO.
A computer with Wi-Fi and a DVD drive.
BackTrack will work with the wireless card
on most laptops, so chances are your laptop
will work fine.
However, BackTrack doesn’t have a full
compatibility list, so no guarantees. You’ll
also need a DVD drive, since that’s how
you’ll boot into BackTrack
how WPS creates the security hole that
makes WPA cracking possible. This is a 4-
step process, and while it’s not terribly
difficult to crack a WPA password with
Reaver, it’s a brute-force attack, which
means your computer will be testing a
number of different combinations of cracks
on your router before it finds the right one.
Let’s Get Crackin’At this point you should
have BackTrack burned to a DVD, and you
should have your laptop
Steps:-
1: Boot into BackTrack
To boot into BackTrack, just put the DVD in
your drive and boot your machine from the
disc. During the boot process, BackTrack will
prompt you to to choose the boot mode.
Select “BackTrack Text – Default Boot Text
Mode” and press Enter. Eventually BackTrack
will boot to a command line prompt. When
you’ve reached the prompt, type startx
and press Enter. BackTrack will boot into its
graphicalinterface.
2: Install Reaver Update:
This step is no longer necessary, as Reaver
comes pre-installed on Backtrack 5 R3.
3.Reaver has been added to the bleeding
edge version of BackTrack, but it’s not yet
incorporated with the live DVD, so as of this
writing, you need to install Reaver before
proceeding. (Eventually, Reaver will simply
be incorporated with BackTrack by default.)
To install Reaver, you’ll first need to connect
to a Wi-Fi network that you have the
password to crack.
Click Applications > Internet > Wicd Network
Manager
Select your network and click Connect, enter
yourpassword if necessary, click OK, and
then click Connect a second time.
Now that you’re online, let’s install Reaver.
Click the Terminal button in the menu bar (or
click Applications> Accessories > Terminal).
At the prompt, type: apt-get update
And then, after the update completes: apt-
get install reaverIf
all went well, Reaver should now be
installed. It may seem a little lame that you
need to connect to a network to do this, but
it will remain installed until you reboot your
computer. At this point, go ahead and
disconnect from the network by opening Wicd
Network Manager again and clicking
Disconnect.
3. Gather Your Device Information, Prep Your
Crackin’In order to use Reaver, you need to
get your wireless card’s interface name, the
BSSID of the router you’re attempting to
crack (the BSSID is a unique series of letters
and numbers that identifies a router), and
you need to make sure your wireless card is
in monitor mode.
So let’s do all that.Find your wireless
card:Inside Terminal, type:
iwconfig
press Enter. You should see a wireless device
in the subsequent list. Most likely, it’ll be
named
wlan0,
but if you have more than one wireless card,
or a moreunusual networking setup, it may
be named something different.Put your
wireless card into monitor mode:
Assuming your wireless card’s interface
name is
wlan0, execute the following command to put
your wireless card into monitor mode:
airmon-ng start wlan0
This command will output the name of
monitor mode interface, which you’ll also
want to make note of.
Most likely, it’ll bemon0.
Make note of that.
Find the BSSID of the router you want to
crack:
Lastly, you need to get the unique identifier
of the router you’re attempting to crack so
that you can point Reaver in the right
direction.
To do this, execute the following command:
airodump-ng wlan0
(Note: If airodump-ng wlan0doesn’t work for
you, you may want to try the monitor
interface instead—e.g.,airodump-ng mon0.)
You’ll see a list of the wireless networks in
range
when you see the network you want, press
Ctrl+C to stop the list from refreshing, then
copy that network’s BSSID (it’s the series of
letters, numbers, and colons on the far left).
The network should have WPA or WPA2
listed under the ENC column.
Now, with the BSSID and monitor interface
name in hand, you’ve got everything you
need to start up Reaver.
4. Crack a Network’s WPA Password with
ReaverNow execute the following command
in the Terminal, replacing
bssidandmoninterfacewith the BSSID and
monitor interface and you copied down
above:reaver –
-i moninterface -b bssid -vv
For example, if your monitor interface
wasvmon0 like mine, and your BSSID was
9D:AE:8d:65:1F:B2(a BSSID I just made up),
your command would look like:reaver
-i mon0 -b 8D:AE:9D:65:1F:B2 -vv
Press Enter, sit back, and let Reaver work its
disturbing magic.
Reaver will now try a series of PINs on the
router in a brute force attack, one after
another.
Enjoy.
