Is Your Company’s Website Compromising Customer Data? – Source: securityboulevard.com

If you are a security, compliance, and privacy professional, it’s time to focus on an often-ignored issue—client-side security. While many organizations dedicate significant resources to protecting their servers, there’s a critical question to consider: are you also safeguarding what’s happening on your users’ browsers?

Every time a user visits your website, their browser downloads and runs code. This can range from simple images to complex JavaScript applications. Unfortunately, this is where attackers often strike, exploiting the client-side to access sensitive information like login credentials, credit card data, and personal details. Think of it this way: you wouldn’t leave your home’s front door unlocked, right? Ignoring client-side vulnerabilities is like leaving your front door wide open for intruders.

What Risks Are Hiding on Your Website?

Several sophisticated threats leverage client-side weaknesses, putting both your company and customers at risk:

• E-skimming: Imagine a customer entering their credit card information on your checkout page, unaware that malicious code embedded on your site is stealing it in real-time. This is the essence of e-skimming.
• Formjacking: Similar to e-skimming, formjacking allows attackers to capture any information submitted via web forms, such as usernames, passwords, addresses, and phone numbers.
• JavaScript Injection: Attackers insert harmful JavaScript into your website, enabling them to hijack accounts, redirect users to malicious sites, or directly steal sensitive data.

A Real-World Wake-Up Call

Gusto, a payroll and HR software platform with over 200,000 customers, provides a telling example of the growing threat landscape. Frederick “Flee” Lee, Gusto’s Chief Security Officer, emphasizes how attackers are shifting their focus from traditional server-side approaches to targeting the client-side. The implications are clear: client-side attacks are not hypothetical; they are happening now.

Is Your Organization Vulnerable?

Here are key questions to evaluate your risk level:

1. Do you track all first- and third-party scripts running on your site? Unmonitored scripts could harbor unauthorized trackers or malicious code.
2. Are you proactively scanning for JavaScript vulnerabilities? Attackers innovate constantly; staying ahead of their tactics is essential.
3. Do you utilize automated tools to address vulnerabilities? Manual methods are both error-prone and time-consuming. Automation is crucial for efficiency and accuracy.

Client-Side Security Demands Priority

Convincing stakeholders to prioritize client-side security may require translating technical risks into business impact:

• Quantify the risk: Highlight how a single attack could lead to costly legal penalties, regulatory scrutiny, and lasting reputational damage.
• Share real-world examples: Use cases like Gusto’s proactive approach can demonstrate the importance of addressing client-side vulnerabilities.
• Make it personal: Illustrate how client-side breaches could undermine customer trust—a loss no organization can afford.
