and malware loaders becoming the most prevalent attacks targeting online retailers. These sophisticated criminals are after your customer data, and they're getting smarter about how they gain access to your website's admin controls.

The good news? You don't have to become another victim. By implementing these essential security measures, you can significantly reduce your risk and protect both your business and your customers.

The Current Threat Landscape

Digital skimmers and loaders represent the most common malware we encounter across the eCommerce world. To deploy this malware on target sites, cybercriminals must first gain control of website admin panels. These attackers are technologically savvy, persistent, and specifically targeting customer payment data during checkout processes.

The key to defence is understanding that criminals typically target "low hanging fruit" - poorly secured sites that are quick and easy to compromise. By implementing basic security controls, you can move your website out of this vulnerable category.

Critical Security Actions Every eCommerce Site Must Take

1. Secure Your Admin Access

• Hide Your Admin Panel - Moving your admin login from its default location to a discrete URL is one of the most effective first steps. Additionally, restrict access to this URL to a limited number of trusted IP addresses. This simple change makes automated brute force attacks significantly more difficult to execute.

  
  

• Enable Multi-Factor Authentication - Implement 2FA using tools like Google Authenticator or Authy for all admin accounts. This additional layer of security is simple to implement, cost-effective, and highly effective against both brute force attacks and credential compromises.

  
  

• Carefully review all user accounts - Review each and every user profile both on the operating system and in the Wordpress/Magento or other framework administration settings. Disable or remove user profiles that are unknown to you or profiles that are not absolutely necessary.

  
  

• Create Individual User Accounts - Eliminate shared logins entirely. Each user must have their own credentials, allowing you to track access and changes made by specific individuals. This accountability becomes crucial if an account gets compromised, enabling you to quickly identify and roll back malicious changes.

  
  

• Remove Inactive Accounts - Conduct a thorough audit of all user accounts and immediately delete any that are no longer needed. Inactive accounts represent unnecessary security risks that criminals can exploit.

  
  

• Enable access logging - Ensure you have a record of when each individual user logs into the system. This should include both operating system logon events and users logging into the website admin panel. Ideally this should include the network address being used to access your hosts, so you can perform geo-location on the addresses as well as identify anomalies in the sources being used to access your environment.

  
  

• Update ALL user passwords - It is important to update absolutely all user profile passwords in one batch or operation. Staggering these changes provides any potential threat actors that may have access to your environment an opportunity to survive this password update, and in this situation you're back at square one.

2. Keep Your Software Updated

• Apply Security Patches Immediately - When software vendors release security patches, the vulnerabilities they address become publicly documented. This creates a "paint-by-numbers" guide for exploitation, making unpatched systems easy targets. Delayed patching essentially puts a target on your website.

  
  

• Review all 3rd Party Plugins - Several 3rd party platform Plugins are known as being either malicious or presenting significant vulnerability to the site. Careful and regular review of all plugins, their suitability and need is strongly advised.

  
  

• Update Third-Party Plugins - Insecure third-party plugins are becoming the foundation of a growing trend in supply chain attacks. Keep all plugins updated to minimise risk from your technology partners and maintain the security of your entire ecosystem.

  
  

• Monitor for Vulnerabilities - Establish a regular schedule for checking missing critical security patches. Proactive monitoring allows you to address vulnerabilities before they can be exploited.

  
  

3. Implement Proactive Monitoring

• Malware Detection - Regular malware scanning helps identify infections before they cause significant damage to your business. Look for solutions that specialise in eCommerce threats and stay ahead of emerging attack vectors.

  
  

• Real-time Checkout Monitoring - Monitor third-party scripts running on your checkout pages in real-time. This practice not only helps detect digital skimmers but also fulfills PCI DSS requirement 6.4.3, which mandates monitoring for unauthorised scripts in payment processing areas.

  
  

• File Integrity Monitoring (FIM) - Track all changes to your website's file system. If changes occur that weren't made by you or your development team, you may have an intruder. Quick detection enables rapid response and damage limitation.

  
  

• Implement Change Control - Particularly if using an external or "off-shore" development team, ensure that the team is working to strict change windows. This would entail the team providing explicit details regarding what is being worked on / updated etc, as well as the timing of the change window (between X and Y on date ABC). This will make monitoring and managing your File Integrity Monitoring (FIM) events significantly easier as the changes will be structured.

  • You will know that all changes between X and Y times on date ABC relate to your developers changes or at least your developers to interacting with the system in this window.

  • You will know (from the change control details provided) what was worked on, so again you can manage the FIM events.

  • Depending on how the development team operate you may even be able to compare what the change control documentation states will be worked on with what was actually changed.

  
  

• Set Up Security Notifications - Configure alerts to notify you immediately of any critical security changes or potential threats. Early warning systems can mean the difference between a minor incident and a major breach.

  
  

• Manual Transaction Testing - performing a manual transaction to validate the correct operating on a regular frequency (such as monthly) is an excellent way to ensure the health of an eCommerce site.

  
  

4. Deploy a Web Application Firewall (WAF)

• Choose the Right Solution - Consider solutions like Cloudflare Business Plan or Fastly Starter Security. These platforms offer comprehensive protection against common internet attacks while providing additional benefits.

  
  

• Virtual Patching Capabilities - Advanced WAFs can provide "virtual patches" that secure your website while you develop and deploy permanent fixes. This capability is particularly valuable when immediate patching isn't feasible due to complexity or resource constraints.

  
  

• Additional Benefits - Many WAF solutions include CDN capabilities, performance optimisation, and DDoS protection, making them cost-effective investments that improve both security and site performance.

  
  

Why These Steps Matter

The statistics are sobering: thousands of eCommerce sites are currently compromised with various types of malware. A significant percentage of these sites have exposed admin panels in default locations, making them easy targets for automated attacks.

Digital skimmers and Loaders specifically target checkout processes, stealing payment data as customers complete their purchases. The financial and reputational damage from such attacks can be devastating, including:

• Direct financial losses from fraudulent transactions

• Regulatory fines and compliance violations

• Loss of customer trust and loyalty

• Damage to search engine rankings and online reputation

• Potential legal liability for data breaches

Taking Action

These security measures are neither difficult nor expensive to implement, yet they can make the difference between business success and costly security incidents. The investment in basic security controls is minimal compared to the potential cost of a successful attack.

Start with the most critical steps: secure your admin access, enable multi-factor authentication, and ensure your software is current. From there, implement comprehensive monitoring and consider deploying a web application firewall for additional protection.

Moving Forward

Criminal tactics will continue to evolve, but the fundamentals of good security remain constant. By implementing these essential security steps, you're not just protecting your current operations - you're building a foundation for sustainable, secure growth.

Remember that security is an ongoing process, not a one-time setup. Regular reviews, updates, and monitoring are essential to maintaining effective protection against evolving threats.

Your business and customers depend on you taking these steps seriously. Don't wait until after an attack to implement these crucial protections.
