i've seen something différent betwenn plesk9 and virtualmin
i use joomla for website
on plesk 9 the files have the right rw-r--r-- (Write for owner) and the dir have rwxr-xr-x and the files was not update by a php page
on virtualmin i've to do r--r--r-- for the files and r-xr-xr-x for the dir
do you think a rw-r--r-- and rwxr-xr-x can be the raison of the hack ?
What is the good acces right to put on file and dir ? and to public_html ?
