What is the most locked down file permission I can give to all the index.php files in a typical WordPress install?
My site is constantly being attacked and my index.php files are frequently being rewritten. This seems to be the only files are that targeted.
I routinely change my FTP password but this does not solve the problem.
I forget what I have the file permission set to now but I do know it is what was issued by WordPress when it was installed in the default fashion.
