RE: Password Audit tools

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.

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 ;)
