Linux Docs - WLAN hacking Author: Sven Knispel Updated: 03-10-2005Feedback welcome: linux@cri.ch Free service provided by: www.cri.ch Hacking other people's WLAN is illegal and unethical. This article is not about penetrating foreing WLANs but about learning someting about security. The techniques described here apply the encryption with WEP, not WPA. I have successfully installed the tools on Fedora Core 3 (FC3) and Fedora Core 4 (FC4). It is amazing how many believe that hiding their SSID or rejecting foreign MAC addresses is secure enough. Installing and using kismet, aireplay, airodump and aircrack Collecting encrypted packets Cracking the WEP key from collected data Common techniques and attacks on WLANs For those who don't want to configure their Linux to do this there is pre-configured Live CDs worth looking at: The Auditor distro from Remote Exploit 1. There are many source about this matter. 2. Note these steps are not required if you use a Live CD. 2.1 Kismet 2.2. 3. 3.1. 3.1.1. 3.1.2. 3.2. 3.3. 4. 4.1.

Configurer son interface Configurer son interface Cette page rassemble des informations sur la configuration de carte réseau. Les divers modes Une carte réseau dispose de plusieurs modes (monitoring, ad-hoc, ...) selon son cas d'utilisation dans un réseau. Ici nous vous proposons une liste de commandes pour mettre votre carte dans ces modes. Mode Master/AP On est en mode "Access Point", autrement dit, il représente le passage vers le réseau éthernet, on peut l'appeler maitre ou père du réseau. Mode Managed Ici, on représente qu'un client du réseau sans fil, on peut l'appeler esclave ou fils du réseau. Mode Monitoring / Promiscuous Le mode monitoring (ou "surveillance") est une notion appartenant aux réseaux sans fil, où nous ne sommes pas associé/connecté aux réseaux écoutés. Mode Ad-hoc Le mode client à client, vous pouvez constituer ainsi un réseau sans AP... Mode Repeater Vous êtes un relayeur de signal, pour étendre la portée de l'AP. Configuration avec iwconfig et ifconfig bt ~ # ifconfig rausb0 up Usage : Avec le WPA

[valgasu] Nmap Online Essential Wireless Hacking Tools By Daniel V. Hoffman, CISSP, CWNA, CEH Anyone interested in gaining a deeper knowledge of wireless security and exploiting vulnerabilities will need a good set of base tools with which to work. Fortunately, there are an abundance of free tools available on the Internet. This list is not meant to be comprehensive in nature but rather to provide some general guidance on recommended tools to build your toolkit. Please put these essential wireless hacking tools to safe, legal and ethical use. Finding Wireless Networks Locating a wireless network is the first step in trying to exploit it. Network Stumbler a.k.a NetStumbler – This Windows based tool easily finds wireless signals being broadcast within range – A must have. (NetStumbler Screenshot) Kismet – One of the key functional elements missing from NetStumbler is the ability to display Wireless Networks that are not broadcasting their SSID.
