This might help....ive posted this before..

Here is a link (its cached from google) that a trainer from Foundstone
showed me (his website) of the 51 most common passwords that worked 80% of
the time to penetrate a network

http://66.102.7.104/search?q=cache:N60gEe8eS8UJ:hig.beesecure.org/r005_passw
ord_guessing_works.html+51+common+passwords+beesecure&hl=en&client=firefox-a

if the link doesn't work here is the article itself:

There are many "Default Password Lists" on the internet that are fairly
comprehensive. Many of them are too big. Over the past few years, I've
compiled a personal list of passwords that I've run across. When doing
internal assessments against NT environments, one of these 51 passwords get
me in 80% of the time. I'm interested in adding to this list. Please send
me any common passwords (for Domain Admin's) you may have run into.

Begin list:

123456
1234567
12345678
123asdf
Admin

administrator
asdf123
backup
backupexec
changeme

compaq

dell
dmz
domino
exchadm

secret
sql
sqlexec
temp

temp123
test

test123
tivoli
veritas

KKKKKKK

End List.

When I brutre force, I use username:username first, then this list. Do
*not* forget to include a blank line in the above password list. Many
accounts have blank passwords. That's it.

Subject: passw0rd trial limit

hi

i am trying to pen test a web site

site has a login page and all the usernames are known the passw0rd length
is fixed and 6 characters long

i think with a brute force attack it wold be easy to login as any user,

but the problem is when a user enters wrong paaw0rd more than five times
he/she can only login for aboout 2 hours later

how this obstacle can be overcomed do you have any idea?

by the way remote server accepts another user login wehther you have
exceeded trial limit or not so i think it is not related with the ip
filtering
