HELP/GUIDE: LM Brute Force

[madcatter]

Thanks for the reply =]

Thanks for the details. As not a single hash was cracked there must be something wrong. Can you crack the LM and NTLM example hash from here: https://hashcat.net/wiki/doku.php?id=example_hashes ?

I added the LM hash for HASHCAT at the top of the ntds_lm.hash file and ran:

Code:

oclHashcat64.exe -m 3000 %WORKDIR%\ntds_lm.hash -a 3 -1 ?u?d?s ?1?1?1?1?1?1?1

The result I got after ~5 minutes:

Code:

So, is there something wrong with my data-set? I'll try another password dump utility and try grabbing some hashes from my machine. (I just assumed the output from quarkspwdump was fine, has all the expected data)

... I don't suppose the hashes being in upper/lower case matters?
