As a last step we crack WEP key by using captured packets and aircrack-ng command.# airodump-ng -c 1 -bssid XX:XX:XX:XX:XX:XX -w Documents/logs/wep-crack mon0įill in your actual information before running the command, and leave it running. To get your capture, you’re going to run the same command as before, but you’ll specify your BSSID, channel, and the log location. That capture log will be needed by Aircrack to run a brute force attack on the network later. Next, you’re going to log the results of a scan to a file.Look for it, and note the BSSID and the channel that it’s on. You only need information about the network you wish to crack. You can see a table of data pertaining to wireless networks in your area. Dump the results of the monitor into a terminal, so you can see them.The result of the command will give you the name of the new virtual interface. How to crack a wireless WEP key using aircrack-ng.How to install aircrack-ng on major Linux distros.
The guide assumes that your have wireless network card installed and that it supports monitor mode. In the following sections, we’ll guide you through aircrack-ng installation on Linux, then show you the step by step instructions to crack a wireless WEP key. The key which fits to decrypt captured packets is the key used by wireless network to encrypt its entire wireless communication with its connected stations. To crack the WEP key, a hacker needs to capture sample packets not intended for his own network interface and run crack program to compare testing keys against WEP key bundled with captured packets in attempt of decryption. However, if one node sets its own network card into promiscuous mode it will also receive packets which are not addressed for its own MAC address.
The same principle also applies for wireless networks. Each host receives packets only intended for MAC address of its own interface. The basic principle is that communication between two nodes on the network is based on the MAC address.
WEP ( Wired Equivalent Privacy ) is quite easy to crack as it uses only one key to encrypt all traffic. This can be done by sniffing a wireless network, capturing encrypted packets and running appropriate encryption cracking program in an attempt to decrypt captured data. This article shortly describes simple steps on how to crack a wireless WEP key using aircrack-ng software.
