Mandatory information about my setup:

Have I read the related troubleshooter articles above before posting (which pages?)? Yes
Have I searched the tickets before posting? Yes
Have I read the documentation before posting (which pages?)? Yes
Joomla! version: 2.5.11
PHP version: 5.3+
MySQL version: 5.5+
Host: Siteground
Admin Tools version: 2.5.4

Description of my issue: This is not a bug in Admin Tools or a problem with the extension. Recently I have observed thousands of security exceptions. Someone robot is trying to enter random usernames and passwords in the admin area. I use a secret parameter in the admin URL. However that seems to be bypassed by the hacker by using the following URL:
site.com/administrator/index.php?option=com_login

This URL and the wrong sets of usernames/passwords are logged in the Admin Tools exceptions area.
Please let me know how I can stop the hacker from accessing the admin area via the above URL.

No, what happens is quite different and has to do with the way the security exceptions reporting and Joomla! application routing works. The blocking works by hooking into Joomla!'s application events. The secret URL parameter hooks into the onAfterInitialise event whereas the failed login hooks into the onAfterDispatch event which is triggered later on. In this specific case the last protection to be triggered is the one that gets logged. Even if the attacker did guess the correct username/password he would still receive a redirection to the site's front-end and not be able to log in.
