This is an untested theory, but I don’t see why it wouldn’t work. Anyone who wants to prove it either way is very welcome to comment on the matter below.
Ok. Say you have the following exerpt from an /etc/shadow file:
root:awac7eQv2CT0g:12685:0:10000:::: billybob:$7$b1XHzqR5$RJxOyHRAix2rVmtXyHkLikmnod.z94P6vSL1h8ZeUdY/urvOvkvJjg2hn/J0r90YAdAA8HedGIPR2D7.zIzJS0:14438:0:99999:7::: Both passwords in clear text are “uncrackable”. Here is where the trick comes into it. We use the weakness in LM hashes to crack the password (as long as it’s under 15 characters of course).
