Re: [PEN-TEST] Cracking a Stolen SAM

["Dunker, Noah" <NDunker () FISHNETSECURITY COM>]

This was discussed here, or another securityfocus list
a while ago.  showcode.asp actually eliminates some non-
printable chars needed for it to have the correct
structure.  You'll (as far as I've seen) never be able
to crack it because it's a "damaged" sam file.  I don't
think anyone's been able to fix it, so I'd say the file
is pretty much trashed irreperably, unless you can find
a different way to access the same file.

Subject: Cracking a Stolen SAM


Friends:

I'm currently performing a penetration test, and I was able to access the
SAM file located in the WINNT/repair directory.  Specifically, I exploited
the showcode.asp vulnerability to "see" the sam._ file in the \WINNT\repair
directory.  I screen-scraped the relevant contents to a Notepad file, and
saved it.

Here's where I began to guess.  First, I ran the file (I named it sam._)
through l0phtcrack and through the cracker on CyberCop, but it didn't take.
I then ran the file through the Windows "expand" command, and ran the
resulting file through the tools.  Still nothing.

Here's where I'm stuck.  I'm assuming that there are some funky control
characters in the screen-scrape file that I don't know about.  I tried some
traffic analysis work on the file, but I quickly got a headache.

Can anyone please help?  Thanks.

Florindo
