Promiscuous mode ... Hack wifi (WPA/WPA2-PSK). « Variable. Просмотров 1984 All the action takes place in the operating system Backtrack 5 , and they are similar for other operating family Linux, after installing the necessary packages: sudo apt-get install aircrack-ng If not help then: wget tar-zxvf aircrack-ng-1.1.tar.gz cd aircrack-ng-1.1 make make install To start the GUI (desktop) Backtrack write: startx Stages of cracking: We translate the interface to the «monitor mode»Find the network protected with WPA2 Pre Shared Key andGrab all the packagesDeavtorizuem client to capture the initial packet exchange.Break open the key using a dictionary.
To get started find out the name of our wifi card and translate it into the mode of «monitor mode»: ifconfig wlan In our case, the name of the adapter in the system — wlan0 translate in the monitor mode airmon-ng start wlan0 Done, and now we can use the card as mon0 Now scanning for available wireless networks that use WPA2 / PSK: airodump-ng mon0 aireplay-ng -0 1-a 00:25:86:25:9 b: 2c-c 00:1 F: 33:06:5 C: CC mon0. Easily Crack WPA Or WPA2 PSK Under 10 Hours. WPA or even WPA2 can be easily cracked under 10 hours provided that WPS is enabled on the router.
The software we'll use is reaver. The hardware I'm using is Intel(R) PRO/Wireless 3945ABG/BG on Ubuntu 11.04 and driver is iwl3945. First install the necessary libraries to compile the software. Run the following command in terminal to do so. sudo apt-get install libsqlite3-dev libpcap0.8-dev build-essential Now open terminal and go inside /tmp folder. . After this reaver will be installed on your system. Sudo apt-get install aircrack-ng Now comes the attacking part. First of all we have to enable monitor mode on our wireless interface. You can also use ifconfig command to bring the interface in monitor mode. Now let's check if the AP has WPS support. Cracking_wpa. Version: 1.20 March 07, 2010 By: darkAudax Introduction This tutorial walks you through cracking WPA/WPA2 networks which use pre-shared keys.
I recommend you do some background reading to better understand what WPA/WPA2 is. The Wiki links page has a WPA/WPA2 section. The best document describing WPA is Wi-Fi Security - WEP, WPA and WPA2. WPA/WPA2 supports many types of authentication beyond pre-shared keys. aircrack-ng can ONLY crack pre-shared keys. There is another important difference between cracking WPA/WPA2 and WEP. The only time you can crack the pre-shared key is if it is a dictionary word or relatively short in length. The impact of having to use a brute force approach is substantial. IMPORTANT This means that the passphrase must be contained in the dictionary you are using to break WPA/WPA2. There is no difference between cracking WPA or WPA2 networks. It is recommended that you experiment with your home wireless access point to get familiar with these ideas and techniques. Casser une clé wep/wpa avec la suite Aircrack-ng. Introduction Ce tutoriel met en avant un cas simple de crack de clé WEP/WPA-PSK.
Le but est de vous familiariser avec les faiblesses du réseau WIFI. Il nécessite une carte 802.11b/g avec les drivers préalablement patchés pour l'injection. Lexique AP (Access Point) : Un point d'accès est un récepteur réseau (ici sans fil), permettant de relier un client sans fil, à un réseau. Présentation des outils nécessaires Airmon-ng Mettre en mode monitoring votre carte réseau sans fil. Airodump-ng On pourra rechercher des réseaux sans fil grâce à airodump-ng, il permet également de capturer les flux de ces réseaux, indispensables pour trouver la clé. Aireplay-ng Ce programme servira à générer des paquets qui augmenteront le trafic de l'AP(Access Point).
Airolib-ng Gestionnaire d'essid et de table de hash, ceci optimise de manière considérable le bruteforce lui faisant gagner un temps précieux. packetforge-ng Aircrack-ng Aircrack-ng, implémente l'attaque FMS (et d'autres plus poussé comme KoreK). Aircrack-ng. Tutorial. Videos.
