title: What would regenerate a WordPress index.php file
body: <p>So I have a client's site that has been hacked in the index.php file. The hack contains variables like this:</p>
  
  <pre><code>$O0O_O00O__=urldecode("%6E1%7A%62%2F%6D%615%5C%76%740%6928%2D%70%78%75%71%79%2A6%6C%72%6B%64%679%5F%65%68%63%73%77%6F4%2B%6637%6A");
  </code></pre>
  
  <p>I've done some ssh stuff and found some shell exploits that I removed. But, when I delete the code from the index.php and save it back to the server, and I refresh the ftp to see the file size, within a second, the file is right back to the hack being in there.</p>
  
  <p>What am I missing? What would re/create the index.php file like this?</p>
