Cracking User Logins With Hydraįor the dictionary attack we are going to use Hydra. our next task is to issue a dictionary attack against SSH using these usernames and the rockyou.txt word list and see what we can find. Now we can enumerate the server for possible usernames on the remote system./enum_smtp_ rbarnes user exists egill user exists mfoley user exists gramsey user exists aruiz user exists bwise user exists cgoodman user exists ptucker user exists aclayton user exists like we found some valid combinations using only first and last names. SNIP - #!/usr/bin/env perl use strict use warnings use Net::SMTP open(my $fh, ') $s->quit - SNIP. We can write a small script to enumerate a list of users instead of doing it manually. In this example we will be using the VRFY command to enumerate users since we know its allowed on the server. There are 3 ways we can see if users exist on the system. Our list should look something like so: cat en.txt | sort | head -n 15 a.clayton a_clayton aclayton amanda amandar arden ardenc a.ruiz a_ruiz aruiz barnesr blake blakew b.wise b_wise Verifying mail users using VRFY command We need to create a list of potential users on the system from a list of names we got during OSINT.Įmployee Names from Company Website ray barnes eaton gill melodie foley gail ramsey amanda ruiz blake wise chanda goodman perry tucker arden claytonįrom here we need to try different combinations of first and last name.Įxamples: Ray Barnes = `rbarnes` Ray Barnes = `rayb` Ray Barnes = `r.barnes` Ray Barnes = `ray` Ray Barnes = `ray_barnes` etc. 220 ESMTP Sendmail 8.15.2/8.15.2/Debian-8 Fri, 19:31:58 -0700 HELO 250 Hello, pleased to meet you quit 221 2.0.0 closing connection Connection closed by foreign host.
