My Joomla 2.5.4 site was cracked last night. Moreover, the Joomla forum is currently down, and I can\'t even run Joomla\'s diagnostic utility. (fpa-en.php)
I have fo
Couple of steps that will help you identify the point of access. Also depends on if you have access to some server side tools.
Fixing the hack 1. Change all your passwords - 2. Install project honey pot. 3. Admin tools install is good but you need the pro version to really gain access to the security tools. 4. Migrate to a host that specializes in Joomla platforms, in most cases they already have the accounts configured for common security issues in Joomla.
Getting hacked really sucks... Good luck!
Relocate your administrator page by editing the config.php files .. and edit your FTP permission settings. If your administration login url was the standard location. (www.site.com/administrator ) change this location and block access using your hosting control panel to only certain ip address (and even restrict access by hours of availability. How many administrator user accounts do you have. There really should be only one person with super user access . It is really not productive or safe to have other users that do minor edits of the website with administrator privileges; and they could accidentally cause issues. These are basic steps and there is a lot more you can do. Send an email if you need help/step by step instructions. Hope all goes well.
After you recover from this, make sure you place a password on the /administrator directory with .htaccess, assuming this is a Linux based server.
Firstly, reset the passwords of all the administrators, including yours, then change them and ensure they include letters and numbers. Then change the password for the host control panel using the password generator if they provide one. If not, use a password generator online. Once this is done change the password for your database username and don't forget to also update the configuration.php with your new password.
Secondly, download and install Admin Tools which will add more security to your site for the future. Admin Tools also comes with an Emergency Offline button which is useful.
Then download and install Saxum IP Logger which will trace all the registered users, giving you their IP address, country and so on and you can also block IP addresses using the plugin that comes with it.
Next, go to the host control panel and look at the logs to see which IP addresses have entered your website and while files they have accessed. The IP address that coresponds to the files edited, you can then block using the plugin I mentioned before. Joomla 2.5 is very hard to hack so it is rather likely you have an extension that is badly developed and allows SQL injection. Therefore you should always choose popular extensions to install on your website when they are database related.
Hope this helps you in the future. Regards
EDIT : You can also password protect your folders in the FTP for additional security.
