Subject: New Microsoft SQL Server Plugins!
Date: Thu, 3 Jan 2002 15:36:15 -0600
From: H D Moore <[EMAIL PROTECTED]>
To: [EMAIL PROTECTED]
I rewrote my SQL Server blank "sa" account plugin and added another one to
brute force user accounts, comments are welcome!
-HD
##
#
# MSSQL Brute Forcer
#
# This script checks a SQL Server instance for common
# username and password combinations. If you know of a
# common/default account that is not listed, please
# submit it to:
#
# [EMAIL PROTECTED]
# or
# [EMAIL PROTECTED]
#
# System accounts with blank passwords are checked for in
# a seperate plugin (mssql_blank_password.nasl). This plugin
# is geared towards accounts created by rushed admins or
# certain software installations.
