Linux: wepcrack quick howto
This article presents the steps to follow in order to use wepcrack (wifi / wep crack).
Needed software
Before starting, you need the following:
- Linux’s wireless tools (iwconfig, etc.)
- airodump
- aircrack
First Step
We first need to configure the wireless card to listen for all packets it can receive:
|
1 2 3 4 |
iwconfig wlan0 mode Monitor wconfig wlan0 channel wpriv wlan0 monitor_type 1 fconfig wlan0 up |
Second step
We now need to dump packet and store them to a file. Be ware that a lot of packets are needed in order to make wep key crack possible.
|
1 |
airodump wlan0 wlan.pcap |
Finaly…
We can now use aircrack on the previously generated file (see aircrack usage). For example, to search a 128 bits wep key use a 2 cores cpu:
|
1 |
aircrack -p 2 -n 128 packetsFile.cap |
