How to do a real-brute-force ?

How to do a full brute-force operation ? I think the password is 9 characters-long but I'm not sure so masking is a bit useless for me.

Code:

cudaHashcat64.exe -a 3 -m 400 -i --increment-min=3 --increment-max=12 hash.txt

^This does a full lower-case alphabet brute-force from 3 to 12 character lenght, right ?

No. You're not specifying a mask, so it's using the builtin mask as documented on the wiki:

To do a "full lower-case alphabet brute-force from 3 to 12 character" you'd add the mask "?l?l?l?l?l?l?l?l?l?l?l?l" to your current command. To do a "full brute-force operation" with all possible characters you'd use the "?a" builtin character class instead of "?l".
