It has now became common to see more than 1 botnet trying to hack numerous Joomla sites at any given time.
The attackers appear to use a bot to 'brute force' guess the passwords for your admin user on the Joomla system.
To thwart this ongoing attack we have added global Joomla brute force protection.
When you access your Joomla admin area you will be presented a screen that looks like the following :
In this example in the username box you would enter
bc19ip
and in the password field
23
You will then gain access to the login box for wordpress.
If
this causes problems with your site, or you do not want this super
protection, you can add the following to the .htaccess file in your
Joomla administrator folder
Satisfy Any
This single line added to a .htaccess file in the 'administrator' folder will disable the protection for your Joomla.
