    Angry Using rainbow tables to crack wpa

    I downloaded the rainbow tables available on the church of wifi website, extracted the files, and am now presented with a .rt file that i cannot get loaded into cowpatty or aircrack. I have googled for a solution also searched the forums to no avail. Any suggestions?

    Find other tables, the CoW ones are small, out of date and not very useful.

    You could always pay $10 to submit them to pureh@tes cracker as well - $10US is easily covered by even a basic pentest rate.
    Still not underestimating the power...

    There is no such thing as bad information - There is truth in the data, so you sift it all, even the crap stuff.

    Default The purpose of this:

    The purpose of this activity is to educate myself. Not to pay someone to do it for me! I suppose the church of wifi tables are useless to cowpatty and aircrack am i correct? Or is there another program I can use these tables for to crack wpa?

    Education would be for your own WPA point and wouldn't require anything but your own time to create a genpmk list one should think. Have a look for gotmilk and his videos on the topic, or even Xploitz videos - they show you how to create and use tables.

    .rt by the way makes me think of rcrack - which isn't for wifi.

    The Church of WiFi tables are specifically designed for use with coWPAtty.

    That question really only deserves one answer: RTFM!

    Ive tried reading the manual!

    but i get the following error:


    root@Checkmate:~# ./cowpatty -r psk-01.cap -d lm_alpha-numeric#1-7_0_2400x40000000_all.rt -s ssid
    cowpatty 4.2 - WPA-PSK dictionary attack. <jwright@hasborg.com>

    Collected all necessary data to mount crack against WPA/PSK passphrase.
    Starting dictionary attack. Please be patient.
    Invalid word length: -33
    Found a record that was too short, this shouldn't happen in practice!
    Unable to identify the PSK from the dictionary file. Try expanding your
    passphrase list, and double-check the SSID. Sorry it didn't work out.

    1 passphrases tested in 0.03 seconds: 29.48 passphrases/second

    Any suggestions?

    I told you before to create your own list. If you had done so you would have saved yourself the embarrassment of confirming for us all what I postulated earlier - that you are using the wrong tables for trying to crack WPA - those tables are meant to be used against LM hashes and won't work for WPA or the hashing algorithm therein.

    Edit: Oh, and they're not from the CoW either, they're from the rainbow table project.
