Aircrack - Fast Wep Cracking Tool, got it built, need to start testing Options

[speculatrix]

wep as everyone knows should only be used where either you're just stopping casual drive-by intrusion, or where you don't care TOO much about someone breaking in.

aircrack is a latest generation tool set for capturing, analysing and breaking wep keys.

I've made it build on zaurus, am going to be trying to test it, and I was wondering if anyone else would be interested in giving it a go; I am wondering if my Zonet/Mercury card will be 100% suitable.

so after 6 hours and 15 minutes of wellenreiter running it captured 25,217 packets to a 2.2mb file. I was expecting the file to be much larger. I'm wondering if I did something wrong or didn't have some of the wellenreiter settings set up correctly.

either way, I had aircrack running for over an hour, and for some reason my 1000 went to sleep by itself. I've changed some settings in the light and power app to hopefully prevent it from going to sleep (unless I make it), and left the wifi on (in case the active network will keep it alive too). I'll see if it cracks the wep in the morning.

P.S. I'm impressed that I haven't had any memory issues so far with it

Recommendations:

Aircrack-ptw: Using aircrack-ng, 64 bit wep needs around 400,000 IV's and 128 bit needs a cool million. That being said, you should try to use aircrack-ptw (can google it for info) which needs as less as 20,000-40,000 IVS to crack wep. Ive used it many times and is a great program. If using airodump to capture dont use the --ivs as aircrack-ptw need full capture file.

Injection: Most of the time, you will need to inject packets into the network to generate alot of IVS fast. You will need a wlan cf card capable of injection (AFAIK all prism2/prisim3 cf cards support it). U also need drivers supporting injection such as Hostap. Aireplay-ng is the tool i use to inject and replay packets. Attacks available for client-connected networks as well as client-less ones. I collect 40,000 Ivs in less than 10 minutes on my LifeBook P1510 (1 kg tablet) running backtrack.

I am buying a c1000 (still deciding on supplier) in a few days; if i manage to crack a wep network, i will post a little step-by-step how-to. Hope this helps.

Aircrack-ng 0.9.x has the PTW attack. I just broke my WEP key with under 30000 IVs using 0.9 on my Z.
