Pretty much what the title says, cracking WEP in ~10 minutes, using a live version of Whoppix. Quite neat, will try it out this weekend, see how long it takes me...

Edit: Whoops, wrong forum - had both open at the same time, must have clicked the wrong one - Sorry, can a mod move it to Wifi security please?

Very nice. Though I do have one question. If you are using the live distro ie running from mem where is that 160 meg file going to be stored and still provide enough memory to to process the wep crack. They didn't say if they mounted a local partion (need to be fat to write to it or thumb drive).

The method they used was ust to increase the unique iv by replaying a packet to the network. Very effective. The video was really nice too.

This method defienetely works, i've tried it before on a friends network and its great. But there has to be sometype of activity going on, atleast a little bit, you wont be able to crack a network with no activity. Air replaying is the shit, and the newest beta works with one wireless card = ). As far as storing the file, my files have been something from like 80 - 100 mb. So even a 128 mb usb drive would probably suffice.

topic moved.

I heard it is possible to force the ap to generate traffic by sending some malformed packets. dunno much about wireless though, and I'm sure it would make a 'noisy' attack. anyone knows how that works?

edit: I'll start by watching the vid myself

you can supposedly use void11's tool and have clients disconnect/reconnect which will iuncrease data... ive had a lot of problems with this tho, and have got about 20,000 unique IV's and found no luck cracking with 64/128bit keys... although ive only tried one WEP point, the other ones around here are WPA...
i'll need tro play around with it a bit more when i get some time,

Do you know if exist an void11 tool for windows ? Because my wifi card isn't compatible on a linux kernel Even with a commercial driver(the driver is not stable) :@

you tried ndiswrapper? might do the trick...

In order to use Kismet you will have to get a wireless card that either contains Prism2/2.5 chipset - Or one of the old Hermes I chipsets. They are hard to get now-a-days, but sometimes you can find 'em on eBay!

NdisWrapper is not supported in Kismet as far as I know

Just trying to help dispell that common myth...

Pro21, check if your card works with kismet via the Whoppic Live CD or the Auditor Live CD. If Auditor works, then you've got orinoco, and a like to the patch is on that post.

The bad thing of wep cracking is, that u need a wlan adapter which handles monitor mode. Just a few adapters can work in monitor made
