Help to specify mask/charset/command

[artur3004]

happy easter folks,

I still don't really get the right parameters for my brute-force attack

What I have:
NTLMv2 hash (do i need only the 2nd hashpart or the whole hash like provided?)
Password is 12 to 14 char long (upper/lower/digit/special)
it contains up to 4 special chars

so that's propably

Code:

?a?a?a?a?a?a?a?a?a?a?a?a?a?a

as charset(?)

The following command

Code:

hashcat64.exe -m 1000 -a 3 -o hash.txt ?a?a?a?a?a?a?a?a?a?a?a?a?a?a

is obviously not correct (error token length exception; no hash loaded)

Can someone help me to specify the whole command from incremental 12 chars up to 14?
Thank you very much
