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

You're close but highly doubtful you'll be able to do a 14 characters as that will eat a tonne of memory. You can try though!


Note: -o is your OUTPUT file, not your hash file. Also check the hash examples to see how the hash should look for V2 which is -m 5600 actually, not 1000.

is it because it needs so much memory?
i have 32gb ram and the rx 480 has 8 gb (whyever it only can only allocate half of it)
what specs(ram) would i need to perform this brute force?

No, it's because there are so many possibilities you will never see the attack complete in your lifetime no matter what hardware you have.
