If you have the time and disk space, Rainbow Crack is another very fast cracker. It creates tables of possible hashes based on the parameters you set, such as "lower-case, numeric". It takes about 640 megs for letters and numbers. It takes about 200 GIGS for special and alt chars. When you crack, it is incredibly fast because the work is already done
Something to add to this - frequently when doing pen-tests, you'll find that weak passwords are only alphanumeric. Generating the rainbow tables and popping them onto a CD or large USB thumb drive (or usb hdd) works wonders. Then you can take them with and crack passwords on the spot in minutes. (RainbowCrack will also run from a USB drive.) -- Peace. ~G On Tue, 14 Dec 2004 09:30:35 -0800, John Forristel (SunGard-Chico) <John.Forristel () sungardbi-tech com> wrote:

Miller CISSP Cc: pen-test () securityfocus com Subject: Re: Password Audit tools Internet Scanner does a good job of enumerating accounts on a Windows Domain(using netbios and null sessions) but if you tried to brute force/dictionary every account that it found the scan would take a VERY long time to complete. If you are trying to pw crack through a service (ftp,telnet,http...), use hydra otherwise use LC or John the Ripper. BTW, Nessus also does a good job enumerating accounts, and its free ;) Dan On Mon, 13 Dec 2004 19:10:29 -0600, Jeffrey M.

Has anyone used LC5 and can anyone compare it to ISS? Also are there any OpenSource tools that can do these sorts of checks? Thanks J_
