Hi to all
i am trying to use hashcat in brute force mode to LM and nt hashes with no results
i need a maximum length of characters ->15 with all combinations letters,digits and special characters.
in the begining of all commands i am taking :
Minimum password length supported by kernel: 0
Maximum password length supported by kernel: 7
i tried
Code:
hashcat -m 3000 -a 3 -1 ?l?d?s?u -2 ?l?d?s?u ?1?1?1?1?1?1?1?1?1?1?1?1?1?1 hashes.txt
zsh: no matches found: ?l?d?s?u
Code:
hashcat -m 3000 -a 3 hashes.txt nsa.hcmask
and taking
Quote:Skipping mask '?l?l?l?l?l?l?l?l?l' because it is larger than the maximum password length.
i am running 64bit linux with gtx 970, fx8350 and 24gb ram

Learn how your shell works.
As for your main question; that's impossible. LM hashes can only support up to seven characters.
so hashcat cannot find"translate" a windowsxp login password with 14 characters length?
windows uses two LM hashes to store such long passwords.
with bash and splitted hash
Code:
hashcat -m 3000 -a 3 -1 ?l?d?s?u -2 ?l?d?s?u ?1?1?1?1?1?1?1 hash1.txt

well, you have to start hashcat correctly. Your arguments are out of order.
ok..so could you tell me how hashcat can search in LM hash all the possibles (upper letters down letters digits and special characters) with brute force?
the syntax as mentioned withn the --help output is:
Code:
hashcat -m 3000 -a 3 hash.txt ?a?a?a?a?a?a?a
i.e. the hash (or hash file) must be specified before the mask
thank you very much and if i want to make this for nt windows 7 then i have to execute
Code:
hashcat -m 1000 -a 3 hashes.txt ?a?a?a?a?a?a?a?a?a?a?a?a?a?a
?
but i am taking

Unless you are some kind of divine being there is no use in such an attack. It will surpass the estimated end of our universe.
