How do I go about performing a brute / mask attack on a vbulletin hash with one thread that and it tries every password that is from 5 characters to 10 characters long and uses numbers, letters and symbols ?

Hmm, what about reading help and wiki ?

I did but I don't know If im doing the right thing or not.
is this right?

Yes, you do.

first, you're not going to brute force past length 8 on CPU. you probably won't even get past length 7.
second, you don't need to specify --pw-max
third, -c with -a 3 does nothing
forth, you can replace "-1 ?l?u?d?s ?1" with "?a"

so while your command line works, a more appropriate command line would be:

Code:

Thanks, does this make it more likely to get the password?

Not at all. If the password is length 8 or more, you won't get it but if it's less than 8, you should crack it if it does not contain regional characters.
