RE: [users@httpd] Hacked the website replace the index.hm page

Heya,

PHP as a CGI also requires users (read, typically, morons) to add a
shebang line to their scripts. What we do is put in an open_basedir for
all vhosts at a bare minimum. Another favourite is the mod_suexec module
additions for mod_php (I forget the exact name).

Another countermeasure is mod_security which can block phpBB exploit
attempts (and other common ones).
