What is Magecart?

Magecart is a notorious and insidious threat that targets e-commerce websites with the aim of stealing payment card information from unsuspecting customers. Named after the shopping cart software Magento, Magecart attacks involve the insertion of malicious JavaScript code into compromised websites’ payment processing pages.

How Does Magecart Work?

Magecart is a form of data skimming that attacks by using the client-side browser as the front door for consumer interactions. “Skimming” is a method used by attackers to capture sensitive information from online payment forms, such as email addresses, passwords and credit card numbers. For Magecart specifically, hackers implant malicious code into websites to steal credit card information as people enter credentials on the checkout page.

Data skimming attacks like Magecart typically follow a well-established pattern. They must achieve three things to be successful:

Gain access to your website:
There are typically two ways attackers gain access to your website and place skimming code. They can either break into your infrastructure or your server and place the skimmer there. More often though, they will attack one of your third-party vendors, especially if they are an easier target and infect a third-party tag that will run a malicious script on your site when it is called in the browser.

Skim sensitive information from a form:
There are many different ways that attackers can capture data, but the skimming code is always some sort of JavaScript that listens for personal information and collects it. A common scenario is one in which attackers monitor all the keypresses on a sensitive page or some that intercept input into specific parts of a webform like the credit card and CVV fields. Generally, attackers will hide malicious code inside other code that looks benign to avoid detection.

Send information back to their server:
This is the simplest part of the whole process. Once hackers gain access to your website and scrape the data they want—it’s game over. They can send the information from end users’ browsers to almost any location on the internet.

The Impact of Magecart Attacks

Magecart poses serious risks to both businesses and customers:

Financial Losses:
Stolen payment card data can lead to unauthorized transactions, causing financial losses for customers and damage to businesses.

Reputation Damage:
A Magecart attack can severely impact the reputation of an e-commerce website, eroding customer trust and loyalty.

Legal and Compliance Issues:
Businesses may face legal consequences and regulatory fines for failing to protect customer data adequately.

Extended Downtime:
Detecting and mitigating a Magecart attack can lead to extended website downtime and disruption of e-commerce operations.
