Multiforcer 1.3 Bug

I discovered a bug with the multiforcer and how it counts the total number of hashes. As you can see it has cracked more than the total number. I was attempting to crack LM hashes.

Yeah. I've noticed that.

I'm pretty sure I have an idea as to why, and will be fixing it in future versions. There's a bug with adding cracked passwords that will count some multiple times if they're found multiple times (there's some slight threading overlap to ensure coverage).

Fix for this is committed in the MFN code, and I may get around to backporting it to the current version with a few other tweaks.

Instead of adding each time a password is found, it just queries the hashfile class for cracked/uncracked count. With some duplicate chunks, I think LM shows this worse than other hash types.

Awesome. I was trolling the SVN commit messages yesterday, looks like lots of good stuff.

:) Yep.

Just got my OpenCL BFI_INT patching working...
