What you have there are the challenge/response hashes. You can crack
them with Cain & Abel but prepare for it to take a while. You can't use
Rainbowtables as the nonce is unique for every exchange.
There are tables for a constant nonce to crack the first half of a
LANMAN hash. Here are some resources that may help you understand what
can be done with hashes.

Hi Experts,
After testing a client network, i got a hash through Ettercap(ARP
Spoofing) , but when trying to cracking the hash with RainbowCrack it
seems not to be a NTLM format, and nothing happens.
Here i show the hash gathered:
SMB : 172.16.16.135:445 ->
USER: mjones
HASH:
mjones:"":"":1EA3083687301F2E00000000000000000000000000000000:2F8EDA1AD20B80974F86656996787855C5CF3417FD44BF03:BD9AE7964A5E989B

Do you know how to crack hashes gathered from Ettercap(ARP Spoofing)?
