Wep Network Key
Posted 08 February 2013 - 16:29
Just a quick question. I'm trying to work out whether it's possible to get into a WEP secured WiFi network purely by packet sniffing. I've found loads of tutorials showing how to do it with BackTrack a bit of packet injection, but I'm wondering if you can do it without making a noise?
I was once told that WEP is such a bad idea because at some point the key is transmitted over the network unencrypted, is this true? If so, why can't I find a way to just sniff and read the right packets?

You'll need around 50.000 to 100.000 IVs to quickly crack the WEP. Less can do it - just takes longer time to bruteforce.
[EDIT] Just read up on some theory. It's not in the authentication that the IVs are transmitted, but in general traffic. And the packets injections aren't to deauth the client fromt he AP; but rather to just create traffic to "lure out" more packets with weak IVs.
I think I confused some WPA cracking with WEP...
