Re: Cracking Ettercap Generated hashes

[Kurt Grutzmacher <grutz () jingojango net>]

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.
