MSCACHEv1 Line-Length Exception when username exceeds 12 Characters

[grubbychicken]

Hi philsmd, Thanks for your reply.

I'm using Linux (Ubuntu 11.10 64bit with 4 GPU's).

I'm cracking MSCAHCEv1 not NTLM, but I assume you mean the same problem might be present when cracking MSCACHE?

The command I am using is:

oclHashcat-plus64.bin --hash-type=1100 --attack-mode=3 --outfile=mscache.cracked --outfile-format=3 --increment --increment-min=1 --increment-max=8 -1 ?d?l?u??'!#@*' mscache.txt ?1?1?1?1?1?1?1?1?1

An example of the file I am using is:

*9******235A89063********4D09E*F:lowercase.username.one <<< the real username is 16 chars
*2******3149862BA********EC36B*5:username <<< the real username is 12 chars
*E******C9A5C8BEC********A266D*F:lowercase.username.two <<< the real username is 18 chars

All Tabs, spaces and extra carriage returns have been removed (as i know they have previously caused problems).

This is the error I receive:

WARNING: Hashfile 'mscache.txt' in line 1 (*9******235A89063********4D09E*F:lowercase.username.one): Line-length exception
WARNING: Hashfile 'mscache.txt' in line 3 (*E******C9A5C8BEC********A266D*F:lowercase.username.two): Line-length exception
oclHashcat-plus v0.14 by atom starting...

Hashcat then continues to crack the MSCACHE hash that is 12 characters long, but ignores the hashes with longer usernames.
