I have about 30 wordpress blogs on a server, all being redirected to some russian site. I figured it was the .htaccess file and found the malicious code. I corrected all .htaccess files, for them to be hacked again later on. I realised that the permissions to my wp-config.php files were all set to 666 (publicly editable), so I corrected these. I've just woke up this morning to find all .htaccess files corrupt again. Anyone have any ideas?
