Hacking – How to hack WEP Password with BackTrack ?

Hacking WEP Password is not a new topic anymore since aircrack was first released in 2006. This software suite consists of many tools for detecting, analyzing, monitoring network, sniffing packing and hacking WEP / WPA (Dictionary attack) password. It only supports protocol 802.11x Wireless and network adapter with allows raw monitoring mode (a example list of this type of adapter you can find at following link http://www.aircrack-ng.org/doku.php?id=compatibility_drivers#list_of_compatible_adapters).

Monitor mode is one of 6 modes which a 802.11 wireless card can operate in: Ad-hoc, Master (acting as access point) , Mesh, Monitor, Repeater. Unlike promiscuous mode, which is also used for packet sniffing and can be used on both wired and wireless networks, monitor mode allows packets to be captured without having to associate with an access point or ad-hoc network first and only applies to wireless networks. Therefore be careful when choosing network adapter, you must choose the correct one which stands on the support list otherwise you can not sniff packet from victim network. When I mean “correct”, I mean that it must be exactly same as stated in list. In my demo, I’ll use the USB Wireless Network Adapter “Netgear Wg111v2” which costs about 6 Euro on Ebay. You can find the version of this series on the side of USB stick like the image below.
