What I basically want to do is, perform a test on my Wi-Fi and brute force it instead of a dictionary attack. I googled, and all of them showed me examples of dictionary attack and no bruteforcing.

My password is somewhat like this- aXb2@abc.

I know this can take a lot of time, but since it's my home I can let my computer do the work. Also, is there a better option than bruteforcing this type of passwords? I am using Kali Linux 2. Thanks.

  • You could try to exploit WPS with reaver. That would take much less time than bruteforcing, which could literally take thousands of years. – INV3NT3D Sep 19 '16 at 18:56

Use pyrit instead, it takes a few moments to get used to. It can distribute cracking over the network and utilize GPUs. Never had any luck with ocl-hashcat, but my GPU is worthless anyway. If you have a good one, it's worth looking into. On a weak i5 I get 1300 c/s with aircrack-ng and 1850 c/s with pyrit. It is still far too low of course, you need at least 50-100k c/s to get anywhere. If you prefer, there are numerous good online wpa-crackers. The one I used (years ago, no link) cost 5USD. Wordlists abound, google: 'intitle:"index of" wordlists rockyou pr0n twitter'. Read about common human pw schemes, like CCCCCCNNN, where C denotes alphabetic and N denotes numeric. Hashcat uses this masking pattern for bruteforce baboonery.

I wanted to write RTFM first, but then I found the answer by accident ;-) You can specify

-w - 
as parameter to aircrack-ng and then it will read the passwords from stdin. There are lots of tools that help you generating passwords based on rules. Then you just pipe them into aircrack-ng, for instance:

crunch 4 5 0123456789 2> /dev/null | aircrack-ng [..options..] -w - 

for brute forcing all passwords which consist of digits and are 4 or 5 characters long.
