Windows WEP Crack

Hey guys. I was wondering if any of you knew or could send me a good WEP Crack for windows to test my wireless connection. If anyone new of any (since airsnort isnt really for windows yet) that would be a big help. Thanks.

Tell us how you are securing your connection.... what mechanisms are in place?

i'll have to agree with RoadClosed just asking for that kind of stuff sounds suspicios , like RoadClosed said what messurements areyou using and what services do you have enable or wish to have enable ,one of the comments in your post makes me think that youre running windows butyou didn't said what version. and also you forgot to mention how many other nodes are there if the are, and all that you can provide so that we could try to help with your question.

The original question was pretty clear. He didn't ask how to hack a wireless network and he didn't ask anyone how to secure it. He simply asked us if there was a version of Airsnort for windows. To answer the question: not that I know of. I have a link to forum discussion about your exact question. Apperently, there ways of accopmplishing the same task in windows but there aren't any good apps released for the masses. Your best bet for trying to crack the WEP for your own Wi-Fi network is to use linux and Airsnort and/or WEPCrack.

i hope you realize that cracking the wep on your or any other home network is impractical..you need tons of packets of encrypted info in order to crack the wep of any wireless network. this is easy to do on a hudge network with a few dozen machines creating traffic. if you have it enabled on just one to five pc's though unless you capture packets from the network for upwards of a week you will never get enough packets to crack your own wep.

Thats a good point, what is it 5,000,000 packets or something like that? Could take a very long time...

I remember reading that a utility called kismet was all that could be used to collect enough data to crack WEP. Kismet apparently only runs on Linux boxes and you'd have to sniff anywhere from 500 MB to a gig of data for Kismet to have something to work with.

Thanks guys. If you find out any new info just post.

Perfect timing! The pen-test mailing list @ Bugtraq has been recently buzzing with issues on WEP security and whatnot. Managed to pick up a few helpful posts:

Good luck

what about airsnort

They do have a (semi) working windows port too now..

In all my readings about cracking WEP the general consensus seems to be that it can be cracked after 30-50 million packets are captured. So mnchur is technically correct when he says that on a small home network it would take a while.

As an example, my network has 650 users. Trapping packets entering/leaving the network gets me around 750-1000 packets a second at peak times when I can figure there are probably 100 connections active at any given time. I would consider that "normal" activity insofar as there are few big file downloads or transfers taking place. So, rounding that off you are looking at 10 packets per second per machine. so sniffing 30 million packets from a single machine working 24 hours a day would take about 34.72222 days - more than a month. Looking at it more reasonably the liklihood of the machine working 24 hours per day is low. More likely to see around 4 hours per day on a busy home machine so you need to factor that in giving you a figure in the region of 6 months to gather the minimum amount of data to have a chance of cracking the WEP. I'm guessing that 30 million packets is for a weak key. If the key were stronger then you would need closer to the 50 million packets. In that case we are pushing a year of packet captures to crack the WEP. That should be enough to keep the average skiddie off your WAP.
