title: Magento site down 403 forbidden/ hacked
body: <p>You don't have permission to access /index.php on this server.</p>
  
  <p>Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.</p>
  
  <p>The file permissions for index.php has been changed to 0000 and if I change it to 0755 or even delete the file, index.php gets recreated by itself.</p>
  
  <p>Error log does not show anything. </p>
  
  <p><a href="http://sitecheck.sucuri.net/scanner/" rel="nofollow">http://sitecheck.sucuri.net/scanner/</a> is unable to run malware scans on the website as the website returns 403 Forbidden.</p>
