A university server that I work on quite a bit has been attacked. I am wondering if anyone can give me more information on this kind of attack. A number of PHP pages seem to be replaced with a page that has the following text on it:

Anti - France

We don't need AB(D) to make something.

Make Sure : Your system is secure

The nasty image on the page says:

Hacked by Buster

Here is the URL of a page that has been replaced by the page I've described above:

-- link removed by admin --

I provided the description above as I hope that the SysAdmin will get rid of the hacked page very soon, making this URL not quite as interesting.

Thank you.
