im hoping to work eventually as a penetration tester and im trying to pickup the wireless security side of pentesting

so im experimenting on my own home wireless, WPA2
ive an NVIDIA GTX 550 Ti card

I cracked my own win8 user LM hash in 10 minutes (8characters, upper/lower and number) - pwdump etc
but when trying my WPA2 of a handshake i got from my wireless
using the following syntax:
cudaHashcat-plus64.exe --hash-type 2500 --attack-mode 3 --outfile C:\Users\username\Desktop\capture.hccap.out C:\Users\uername\Desktop\capture.hccap ?u?u?u?u?u?u?u?u?u

now I know my password is 9 digits all uppercase


but it reckons at 12515 H/s it will take more than 10 years to try every combination

can anyone point me in the right direction to optimising this based on the command line I supplied?
there must be quicker ways of bruteforcing this?

many thanks for your help
It's a big keyspace and a slow algorithm so there would be not much optimization to do better without more knowledge. First you can try higher -u and -n settings to see what your card can support. Secondly, if for example your password is GARETHGTT and you know that it starts by GARET, you can use the mask GARET?u?u?u?u. This cut downs the keyspace a lot but you need some knowledge of the password. Otherwise, try dictionary attacks. Bruteforcing is really not the best attack type in your case.

Hey thanks for your reply.

my wpa2 key is something like TCVNNGSXN so how could a dictionary attack work against something like that?
I know I can generate a wordlist of every combination, think it requires about 2TB of disk space, I know with aircrack/crunch if I use something like this command line:
crunch 9 9 ABCDEFGHIJKLMNOPQRSTUVWXYZ | aircrack-ng -b 00:0C:F6:55:E6:6C -w - /root/WPA-01.cap
it generates the file and tests it on the fly without using hard disk space
isn't this just bruteforcing though?
if not how can I leverage this using GPU power instead?
