Re: Drupal site hacked - new php files injected

In addition to updating core and and contributed modules, I'd look at 
how permissions are set up too.
Since i don't update from the admin panel, the only files that can be 
added or changed are in /sites/default/files. You could probably make 
this harder to figure out by changing the names a bit.

I run apache webserver under user 'apache2' and giving write permissions 
only in those directories. The other files are owned by a user and a 
team group account.

I wonder if you could do some more magic by not letting *.php files in 
/sites/default/files be run but downloaded only?
