This tutorial shows how to crack
a WEP key using Airoway in
Wifislax 3.1. For this process it
is necessary to have an
IPW3945 as chipset of the NIC
(Network Interface Card).
Follow these steps :
1.Download Wifislax
from the official page .
2.Burn the downloaded
.iso into a CD in order
to boot it.
3.Reboot the computer
(if necessary) and
boot it .
Press Enter when
necessary .
Elect the option no
pcmcia and press
Enter .
4.Introduce root as
user and toor as
password in order to
login.
5.Introduce now startx
to start the operative
system in graphics
mode .
Go to Start> Wifislax>
Asistencia Chipset>
Asistencia intel pro
wireless> Cargar
ipw3945 inyección -
ipwray-ng; to start
injection mode . The
system must detect
now 2 more network
card interfaces: wifi0
and rtap0.
6.Write in the Shell that
have just appeard
airodump-ng wifi0 .
Take a look of which
WEP encrypted
network (ENC
category) has more
Beacons and pay
special attention on
what channel it is (CH
category) and what's
it's name (ESSID
category) . That will
posibly be the network
with more signal
received.
7.Press Ctrl+C and
introduce airoway .sh.
Move with the cursor
to the channel of the
wanted network and
press Enter when the
wanted network
appear .
8.Elect the network
with the number it
has associated .
Press number 2 . There
will appear some
information refered to
an association. If you
succeed there will
appear this:
Association
successful :-) .
Press number 3 . There
will appear some
information refered to
a reply.
9.Now wait till the
attack 3 (the step
told just before)
comence to catch
ARP's and #Data
category reaches
30000 .
10.Press number 8 when
you have collected
the required Data .
There will appear some
red letters and
numbers. If you
succeed it must appear
a KEY FOUND down in
the window.
11.Write in a piece of
paper both keys (HEX
and ASCII
respectively) .
Tips :
1.Pay special attention to the
encryption type of the
network, it must be WEP
not WPA.
2.To know if your computer
possesses the chipset
IPW3945 you can execute
the command ipconfig /all
in Windows' MS-DOS. You
have to look for Intel PRO/
Wireless 3945ABG
Network Connection. In
other operating systems like
Linux-based ones, you can
download programs like
hardinfo to obtain a
complete list of the
hardware of your computer,
where it would be included
the chipset of your NIC.
This chipset is very common
on laptops.
3.It is better to crack a
network with good signal
because if not, it could be
imposible to do it.
4.When you introduce the
keys on Windows you
should introduce ASCII key
(the second one). You can
introduce the HEX key (the
first one) but without the :.
If you obtain only one key
take note of it and
introduce it in Windows
without the :, if any.
5.The liveCD of Wifislax
sometimes crashes or
doesn't recognize the
injection interfaces. The
solution to this is rebooting
the operating system.
6.Wifislax could be
incompatible with some
computers or need
configuring to work on
graphics mode.
7.If attack 2 (when you press
number 2) don't succeed,
you have to try again later
or crack another network.
8.Sometimes the #Data
needed is superior to 30000
packets. Sometimes
1000000 packets are
necessesary to crack the
key.
9.Sometimes the catch of Data
starts in an hour or maybe
never. You could try later,
rebooting the computer or
changing the location of
your computer.
