If you go on their support forum you will see tons of posts about this, and absolutely no answer. It seems the developer is gone.
Now, there is no way I can keep up with new hacks so I tried and installed RSfirewall. Since then, zero successful attack! And I love that it runs a full security diag on the website and tells you what to change/fix. Great support also from the devs when I updated the website to Joomla 2.5. Five stars, although I wish the functionality was built-in joomla. I learned the hard way that a default joomla install it NOT secure and that there are alot of stuff to do to iron it.
