You can try Curl. It is great tool and it has an option for submitting data
using HTTP POST method. As said before, the problem is you're trying to use
HTTP authentication, instead of submitting the data to the form. I think
that SquirrelMail is using POST method for submitting user data to the
server, so this could be the solution for your problems.

Another important issue in brute-forcing Web logins is the usage of cookies.
Some applications (like Webmin) require you to send the cookie value (which
has been sent in the previous reply from the Web server) as part of your
login request. In this case you must store the cookie value in separate
file, and than use it in your login request (you can do it also with curl,
switches -c, -b).

Best Regards,

Subject: password cracking a web form, tried hydra and brutus


we are conducting a PT for a website. In order to password crack the
login/password form authentication (which happens to be squirrelmail,
written in php, looks similar to the login page of yahoo or msn)  I was
looking for some tools.

I came across Hydra and Brutus. When I tried Brutus on an inhouse dummy
site, after configuring the parameters the target would automatically
become <target>redirect.php. I googled but couldnot find a 
solution to it.

Then I tried hydra at with following command:
# hydra  -l smg -p we2su  http /webmail/src/login.php

it resulted as:
[80][www] host:   login: smg   password: we2su

which is a wrong result since I had given the wrong password.

I get the same result for valid or invalid passwords.

Am I doing anything wrong?

Is there any other tool which does what I'm looking for?

Pls. help me with this :)
