Using rainbow tables to generate windows logon password.

[Tim (PassMark)]

There is a tutorial for windows login password recovery available on the OSForensics website.

Did your password file contain any LM-HASH values or did it only contain the NT-HASH values?

[David (PassMark)]

I think you are doing it wrong.

I suspect you have the wrong set of rainbow tables and the file you are calling an output file is in fact a input file. The input file needs to contain a list of passwords hashes to search for.

Where did you get the rainbow tables from?

In the next day we'll post a tutorial giving a step by step process to recover the windows login passwords.

I have followed the these steps.

Load OS Forensics.
Installed the lm, and md5 rainbow tables.
I added the folders containing the tables, and hit Refresh. They are visable and selectable.
I selected the table by putting a check mark next to it.
I created output file password.txt to save results. (Chose option (Select File)
As soon as I hit Recover Passwords it automatically says finished.

It is though it has done nothing.
