Your Checkout Page Is the Target
- 01
Magecart attacks are invisible
Credit card skimming happens in the browser where traditional security tools can't see it. By the time you discover a breach, thousands of cards may be compromised.
- 02
3rd party scripts are your biggest risk
Marketing tags, analytics, chatbots, and payment widgets all execute in the browser. A compromise in any one of these can lead to a massive data breach.
- 03
PCI DSS v4.0.1 requirements are strict
Requirements 6.4.3 and 11.6.1 mandate script integrity monitoring and authorization of all scripts on payment pages. CSPs and manual audits aren't enough. Learn more about PCI DSS compliance.

Common Client-Side Attacks on eCommerce Sites
Magecart & E-Skimming
Code injected into checkout pages intercept credit card data, CVV numbers, and customer information
Expired Domains
Attackers purchase expired domains of scripts on your site to change code from an approved source.
Software Supply Chain
A breach in one of your trusted providers (analytics, chatbots, marketing tool) can compromise your entire checkout flow.
Dynamic JavaScript
Advanced Magecart variants target specific sessions (high-value orders, certain geographies) to evade detection.
Form Jacking
Malicious scripts copy form data including payment details and send it to attacker-controlled servers
Session Hijacking
Attackers steal session tokens to impersonate customers and make fraudulent purchases
Why Attackers Target Retail & eCommerce:
Payment pages handle credit card data
High-value customer data (addresses, phone numbers, and purchase history)
Checkout flows have multiple third-party dependencies
Seasonal traffic spikes mask malicious activity
Modern web apps load more code in the browser, widening the attack surface.
