Subject: Password Cracking a DMG...
Hello Everyone,
Here's the current situation. I've a 20GB AES-256 encrypted DMG, created
with OS X. I believe I've a partial password. I'm attempting to use John,
but ran into some bugs in the process.
When running dmg2john on the DMG the binary segfaults "Segmentation fault:
11". This behavior was exhibited not only on my original DMG, but any newly
created DMGs of 11GB or greater with no data written. So, it appears to me
with no knowledge of the codebase, this is some kind of filesize issue.
>From what I gather the conversations on Twitter, @gat3way @DhiruKholia
@solardiz maybe have isolated the problem. I'm waiting a patch to be issued
so I can try again.
There we some reports of an all zero hash issue on the DMGs, but that might
have something to do with an on-the-fly patch attempted by @jmgosney. Don't
know if that's helpful or not.
Regards,
Jeremiah-
