It is quite easy to protect your phpFusion installation against any hacking attempt.
For this you use a free script called Crawltrack which you can find at crawltrack.fr. It comes with a detailed instruction on how to set it up for use with many GNU scripts including phpFusion.
After installing the menu will tell you exactly how to insert only a few lines line of code at the right place for protecting your phpFusion installation. All code injections and mysql injections will be blocked, regular updates are supplied and can be downloaded. It will also give you very detailed information on bots and crawlers and is a perfect SEO tool.
I use the cript on all phpFusion and phpBB installations and so far have not been surprised by any attack. I really advise anybody to have a good look at this scipt and use it as a shield against code injections and mysql injections.
You will never be surprised again.
