The buzz around the new PCI DSS requirements for eCommerce is well-deserved - and for good reason.

The evolving threat landscape demands that businesses stay ahead, particularly in securing the checkout process (requirement 6.4.3) and monitoring all scripts loaded during that critical stage. This is a significant leap forward in combating the wave of cybercrime targeting eCommerce platforms.

According to our latest eCommerce ThreatScape Report, March 2024 marked a notable shift in malware tactics, moving from digital skimmers to digital loaders.

Digital skimmers and loaders are becoming a major issue in ecommerce.

Why does this matter?

In simple terms, the industry has largely caught up to detecting digital skimmers, prompting cybercriminals to adapt. To stay in business, they’ve developed a two-stage attack: deploying a seemingly harmless digital loader first, which then calls in a digital skimmer from another compromised domain. This innovation has caused a sharp increase in detected digital loaders—an area where our R&D and forensic teams excel in providing robust detection capabilities.

How does PCI DSS Requirement 6.4.3 help?

This requirement will drastically strengthen the defence for eCommerce sites.

But what else is crucial? File Change Monitoring...

Enter File Change Monitoring (Requirement 11.5.2) - a game-changing tool for understanding and responding to changes in your website’s filesystem.

Imagine this scenario:

  • Your customers report that their payment data may have been stolen from your website—a nightmare for customer trust.
  • Your developers investigate and find malware using a free ThreatView Community licence. They remove the malware and assure you the problem is resolved.

But is it truly resolved?

Without deeper insights, you’re left wondering:

  • What other changes did hackers make?
  • Are hidden malware files still lurking in the system?
  • Will they come back??

Unfortunately, many businesses find themselves in a costly game of cat and mouse, with hackers reinfecting sites within hours of cleanup. This is where a forensic-grade File Change Monitoring system becomes indispensable—and cost-effective.
