how to Bruteforce wpa/wpa2 in GUI mode - datto - 02-23-2012 01:15 AM

Hi
Dont know much about cmd commands , so the Gui mode is great for me.
I have already cracked some handshakes with dict wordlist.
but some i have that i know are 8 digits (capital letters and numbers) have not been solved .
Is there anyone that can tell me some settings within Oclhashcat plus that may solve these handshakes
Thanks

oclhashcat-plus -a 3 linksys.hccap -1 ?u?d ?1?1?1?1?1?1?1?1

mind you bruteforcing wpa will take you a few months

Alot of routers have 8 digit passwords from the broadband supplier, so unless the password has been chaged to a dict word , its not going to be cracked unless your prepared to wait a couple of months. ???
do i put this in the mask box ?u?d ?1?1?1?1?1?1?1?1
as i only know how to use the gui version
i know it may take a couple of months , but i trying to understand how this gui fully works

36 ^ 8 = 2821109907456 combinations. if you gpu (like my hd6990) makes ~190 khash/s its 14847946 seconds -> 171 days. if you say chances are 50% percent you crack it before full keyspace was scanned, 85 days are left = ~3 months.

but, usually the key is not fully a-z 0-9, its just a-f 0-9. in this case cracking time reduces to 16 ^ 8 = 4294967296 combinations. so its done in ~6 days.

I just had a brain-fart... I wonder if it would be worth it to have the program "jump around" the entire keyspace at pre-defined or "random" intervals... What i mean is a new "feature" where the program could do the following until the whole keyspace has been scanned:

Using 1 to 1000 (for simplicity) we could say that the program would work for a random (or pre-defined) period of time on a chunk of the keyspace and then jump randomly to another...

For example:

works from 1 to 120 (for x hours) then jumps to 700
works from 700 to 815 (for x hours) then jumps to 455
works from 455 to 600 (for x hours) then jumps to 940
works from 940 to 1000 (for x hours) then jumps to............

etc etc.. until the whole keyspace is worked through. Now obviously chunks that have been completed will not be worked on again. I wonder if this kind of randomization would increase "luck" of passwords like "zxxzxxzx" which would be found at the very end of a cracking cycle. If we "jump around" on a hash that would take a total of "5 days" for instance, maybe we could get the thing in 20 hours????

omg sl3 techniques

It was silly of me to think that someone had not already pondered these thoughts, but sl3?? that was kind of a surprise to hear that. Do you mean that these are currently in-use, or that people have merely proposed them for sl3? I wouldn't know since I've literally never used -m 1900.

Anyways, does that sound like something at-all worthwhile for really brute "resistant" hash types (or any hashtypes for that matter)?

yeah, they do that. its called "random salt" even if this sounds wrong from a hash-crackers view. however, oclHashcat does not support. i do not believe in this technique.

I requested a feature some months ago that would help speed brute forcing 8 character WPA passwords. A type of Markov filter for maskprocessor would be very useful. However now that oclHashcat-plus has a brute force capability without the need for maskprocessor, the Markov filter request would be suitable for oclHashcat-plus alone.

You can see it here on the features page.

The idea is that it is very unlikely that a random 8 character password would have for example, more than 2 of the same characters concurrently.

Unlikely random passwords. = AAAAEDFT, AAAHBGTP, SDEWZZZZ, ASWZZZZZ ..etc

By allowing the user to select how many times a sequential character can appear would dramatically reduce brute force time. The user could select between 1 (unique characters only) to 8 (meaning that all 8 characters could be sequentially represented. AAAAAAAA.)

I would very much appreciate this feature in oclHashcat-plus as it would save me a lot of time and electricity !! ha ha ! However I have done quite well up to now to restrain my compulsion to “nag” for this to be implemented but I couldn’t hold back when I read this thread. Smile
