Software what you need and where to get them
Airmon-ng For setting card to monitor mode.
Airodump-ng For capturing data for aircrack-ng.
Aircrack-ng For cracking password.
Main steps for cracking WEP
Finding and identificated which network you want to crack (kismet)
Collect data for cracking (airodump-ng)
Use that collected data and run aircrack-ng against it (aircrack-ng)
Get your wireless nic to monitor mode
First we have to check wireless nic modes:
And if you see there example ath0 stop it:
Use airmon-ng to turn your wireless nic to monitor mode so it can receive packages:
Collecting data with airodump-ng
| airodump-ng | Name of that software what you run |
| -c | Channel (From what channel you want to capture data) |
| -w | Set the filename where airodump-ng saves captured data |
| -bssid | bssid of that network which data you want to capture |
| -i | Interface what you want to use for capturing data |
| –encrypt WEP | Capturing data only from networks which are protected with WEP |
If you are lazy and just want to capture everything on the air:
I normally use something between those:
When you have captured some data packages from that network which you wanna crack you can leave airodump-ng running and capturing data and open new terminal window/tab and start to run aircrack-ng.
Cracking WEP with aircrack-ng
Gives you list of those wireless networks which data you have captured to capture.cap file and then you can choose which network you want to crack.
