As the compliance deadline for PCI DSS 4.0.1 approaches on March 31, 2025, organizations must focus on implementing enhanced requirements to protect systems and networks from malicious software (malware). Among these updates is Requirement 5: Protect All Systems and Networks from Malicious Software, which emphasizes advanced measures to prevent, detect, and mitigate malware threats.

Here’s a breakdown of what businesses need to know and implement to meet these requirements:

Understanding Malware and Its Threats

Malware refers to any software designed to infiltrate, damage, or compromise systems without consent. Examples include:

• Viruses, worms, Trojans, ransomware, and keyloggers
• Spyware, rootkits, and malicious scripts

Malware often exploits vulnerabilities introduced via email phishing attacks, portable devices, or outdated system protections. Once inside, it can severely impact systems’ confidentiality, integrity, and availability.

Key Components of Requirement 5

1. Proactive Malware Prevention (Requirement 5.2)

Organizations must actively prevent or detect malware through tailored anti-malware solutions. Regular evaluations help determine whether specific systems are at risk. If systems are deemed low-risk, their evaluation schedule is based on a targeted risk analysis defined in Requirement 12.3.1.

• Purpose: Determine the optimum frequency of risk assessments, ensuring appropriate protection without disrupting operational efficiency.

2. Active and Monitored Anti-Malware Mechanisms (Requirement 5.3)

Anti-malware solutions should:

• Be consistently active, maintained, and monitored.
• Conduct periodic malware scans based on a targeted risk analysis.

• Purpose: Portable media is a common malware entry point. Scanning these devices upon connection reduces risks of introducing harmful code into environments.

3. Anti-Phishing Mechanisms (Requirement 5.4)

With phishing as a primary delivery method for malware, organizations must implement both technical and process-based controls to combat these threats. Recommended strategies include:

• To prevent domain spoofing, we use Domain-based Message Authentication (DMARC), Sender Policy Framework (SPF), and Domain Keys Identified Mail (DKIM).
• Server-side anti-malware solutions and email link scrubbers to block phishing emails before they reach employees.
• Employee training programs to teach personnel to recognize and report phishing attempts effectively.
• Purpose: Phishing often tricks employees into granting unauthorized access. Combining technical tools with employee awareness strengthens the organization’s defenses.

Good Practices for Implementation

While the above requirements are mandatory, several best practices can help organizations enhance their defenses further:

• Regular System Scans: Periodic scans help uncover vulnerabilities in dynamic environments.
• Inventory of Trusted Keys and Certificates: Maintain a registry of cryptographic assets used for malware prevention.
• Network and Data-Flow Diagrams: Use these tools to map potential malware entry points and implement appropriate controls.

Why This Matters

Cyber threats are becoming more sophisticated, and organizations that fail to protect their systems risk significant financial, reputational, and legal consequences. By adopting the updated PCI DSS v4.0.1 malware requirements, businesses can:

1. Minimize vulnerabilities across their networks.
2. Ensure a robust defense against evolving cyber threats.
3. Strengthen customer trust by safeguarding sensitive data.

Getting Ahead of Compliance

The path to compliance isn’t just about meeting deadlines; it’s about building resilient, secure systems that go beyond regulatory requirements. Organizations should begin assessing their current systems, reviewing anti-malware solutions, and implementing both technological and human-centric defenses.

The PCI Security Standards Council (PCI SSC) has introduced significant updates to the Self-Assessment Questionnaire A (SAQ-A), which take effect as of March 31, 2025. These changes impact merchant eligibility requirements and compliance obligations, sparking discussions within the PCI community about what this means for merchants, Service Providers (SPs), and Qualified Security Assessors (QSAs).

---

Overview of the Changes

The latest update to SAQ-A involves adjustments to the compliance requirements for e-commerce businesses that outsource cardholder data processing. Specifically:

1. Removal of Explicit Requirements:
   • PCI DSS requirements 6.4.3 and 11.6.1—which mandate the inventory, justification, and control of scripts on payment pages, as well as the weekly monitoring of HTTP headers—are no longer explicitly required for SAQ-A merchants.
   • Requirement 12.3.1 for conducting a Targeted Risk Analysis to support Requirement 11.6.1 has also been removed.
2. New Eligibility Criteria:
   • Merchants must now confirm that their entire e-commerce site (not just the payment page) is secure and not vulnerable to attacks from malicious scripts, including first-party, third-party, and external scripts that could compromise e-commerce systems.
   • This requirement introduces a broad, high-standard obligation for ensuring protection against eSkimming and similar threats, even without the specific compliance steps outlined in 6.4.3 and 11.6.1.
3. Two SAQ-A Versions:
   • The PCI SSC has released two versions of SAQ-A:
     • The version published in October 2024, which will remain valid until March 31, 2025.
     • A new version, published in January 2025, which reflects these updates and becomes mandatory on March 31, 2025.

“If a merchant is planning to continue using SAQ A in the future, they will now need to ensure that the way they protect against script-originated attacks covers the whole site and not just the payment page. If they can’t do this, they won’t meet the new eligibility criteria, and so they’ll likely need to complete SAQ A-EP instead. This would be a huge uplift, going from 27 applicable requirements in future SAQ A, up to 151 requirements and sub-requirements in SAQ A-EP.” – Gareth Bowker (Jscramber)

---

What Has Changed and Why It Matters

While removing explicit requirements 6.4.3 and 11.6.1 may seem like a relaxation, the underlying security expectations remain stringent. Merchants eligible for SAQ-A must still implement robust eSkimming protections and script controls to meet the new eligibility criteria.

Key points include:

• Eligibility Is Limited: Only a small subset of merchants—those who fully outsource all cardholder data processing (e.g., e-commerce merchants relying entirely on third-party service providers)—qualify for SAQ-A. Most merchants across Levels 1, 2, 3, and most of Level 4 must still fully comply with 6.4.3 and 11.6.1.
• Circular Compliance Challenge: Although 6.4.3 and 11.6.1 are no longer explicitly required for SAQ-A, merchants need script inventory, monitoring, and controls to meet the new eligibility requirement of securing their site from vulnerabilities. This effectively necessitates adherence to the principles of these requirements, even in their absence.

---

What Hasn’t Changed

1. Compliance Deadlines Remain Unchanged:
   • The deadline for compliance with PCI DSS v4.0.1, including requirements 6.4.3 and 11.6.1, remains March 31, 2025. This applies to all merchants not eligible for SAQ-A.
2. No Changes for Service Providers:
   • SPs must continue to comply with 6.4.3 and 11.6.1, ensuring script inventory, monitoring, and the security of payment flows.
3. SAQ-A Merchants Still Need Robust Protections:
   • While the compliance process may appear simplified, the expectation of preventing vulnerabilities (e.g., skimming attacks) remains.

---

Implications for Stakeholders

For SAQ-A Merchants

• Eligibility Challenges:
  • To qualify for SAQ-A, merchants must confirm their site is not vulnerable to script-based attacks. Merchants cannot meet this eligibility requirement without proper script controls and monitoring.
  • Merchants unable to meet these criteria must switch to other Self-Assessment Questionnaires (SAQs) that require full compliance with 6.4.3 and 11.6.1, most likely SAQ A-EP.
• Security Remains Key:
  • The removal of explicit requirements does not eliminate the obligation to secure e-commerce systems. Robust eSkimming protections are essential to safeguard customer data and maintain compliance.

For Service Providers

• Support Your Merchants:
  • Educate small merchants about the importance of script controls and guide them toward solutions that meet compliance requirements.
  • Small merchant clients may misinterpret these updates as a relaxation of obligations, leaving them vulnerable to attacks. Use this opportunity to position yourself as a trusted partner by offering low-burden, cost-effective solutions.
• Expand Your Offerings:
  • Generate additional revenue by introducing value-added services that simplify compliance for merchants while enhancing their security posture.

For QSAs

• Educate and Clarify:
  • Merchants may mistakenly believe that the removal of 6.4.3 and 11.6.1 means fewer security obligations. QSAs must emphasize that the expectation to secure e-commerce environments remains even though explicit requirements have been removed.
• Provide Actionable Solutions:
  • Recommend proven tools, such as Human Security, Source Defense’s platform or Jscrambler, to help merchants implement the necessary eSkimming controls and achieve compliance seamlessly.
• Address FAQ-1331 Concerns:
  • Clarify that Level 1 merchants cannot misuse the updated SAQ-A to bypass compliance with 6.4.3 and 11.6.1. The circular compliance logic ensures that eSkimming protections are required even for SAQ-A eligibility.

---

Summary of Key Takeaways

Opportunities for Collaboration: Service Providers and QSAs can be vital in guiding merchants through these changes and implementing effective solutions.

Changes to SAQ-A: The removal of explicit requirements 6.4.3 and 11.6.1 applies only to a small subset of merchants who meet strict SAQ-A eligibility criteria.

Security Expectations Remain: SAQ-A merchants must implement robust protections against script-based vulnerabilities.

Deadline Remains Firm: All merchants must comply with PCI DSS v4.0.1 by March 31, 2025.

What Is Digital Skimming?

Digital skimming, also known as e-skimming, formjacking, or data skimming, is a type of cyberattack where criminals steal sensitive information entered into web forms. This often includes payment data from online checkout pages or personally identifiable information (PII) entered into other online forms.

These attacks typically exploit vulnerabilities in a website’s infrastructure, allowing malicious actors to inject JavaScript-based skimmers into payment pages, also called Magecart attacks. What makes these attacks so dangerous is their stealth: the payment process appears unaffected, leaving both the customer and the merchant unaware of the compromise.

The Scale of the Problem

Digital skimming is a major and growing problem with devastating consequences for both businesses and consumers. Recent high-profile breaches underscore just how widespread and damaging these attacks can be:

• In July 2024, AT&T admitted that criminals had accessed nearly all call and text data of its 110 million customers over a six-month period.
• A cyberattack on UK pathology lab Synnovis in June 2024 resulted in data theft from 300 million patient interactions, disrupting healthcare services for weeks.
• A breach at Ticketmaster exposed the personal data of 560 million customers, which attackers threatened to publish on the dark web.

These examples highlight the severity of digital skimming and its far-reaching consequences.

The Business Impact of Digital Skimming

The cost of a digital skimming attack goes far beyond the immediate data theft. Businesses face direct financial losses, incident response costs, regulatory fines, and breach notification expenses. For example:

• Kaiser Permanente, a U.S. health insurance provider, revealed that tracking technologies on its website had exposed the private health data of 13.4 million patients.
• Similarly, the U.S. Postal Service faced backlash after tracking pixels on its site potentially compromised the data of 62 million users.

Beyond financial losses, the indirect costs to a business are even more significant. A data breach can damage a brand’s reputation, erode customer trust, and result in long-term loss of business. For instance, Australian prescriptions provider MediSecure declared insolvency just weeks after disclosing a ransomware attack that exposed the data of 13 million people.

How Digital Skimming Works

Digital skimming attacks typically follow a four-step process:

1. Initial Breach: Attackers access a website’s source code or infrastructure directly or through a third-party provider. This is often achieved through software vulnerabilities, malware, or stolen credentials.
2. Code Injection: Malicious JavaScript code is injected into payment pages. Attackers tailor their methods depending on whether payment forms are embedded directly on the page or through an iFrame.
3. Data Exfiltration: When customers input payment or personal data, the malicious code covertly collects and encrypts the information before sending it to the attacker’s server.
4. Monetization: Stolen data is used for fraudulent purchases or sold on the dark web, which can be used for creating fake identities, issuing fake cards, or other criminal activities.

Who Is at Risk?

The short answer: every business.

Cybercriminals don’t discriminate based on the size or nature of a business. Whether you’re a global retailer, a small nonprofit, or a government agency, you’re a target. Criminals seek out cardholder data and PII because of its high resale value and utility in fraud.

The most common type of data stolen in 2024 was customer PII (48%), but employee PII, such as tax IDs and home addresses, is even more lucrative for criminals. If your business collects or processes data, it’s essential to assume it has value to attackers and take appropriate precautions.

The Rise of Magecart Attacks

A specific type of digital skimming attack, Magecart, has become synonymous with skimming payment pages. Named after the Magento e-commerce platform and shopping carts, Magecart attacks involve injecting malicious JavaScript to steal card data inputted during transactions.

Magecart attacks can take two forms:

1. First-Party Attacks: Criminals directly compromise the victim’s website by injecting a skimming code into the payment page. For example, the 2023 breach of DNA testing company 23andMe exposed nearly 7 million user records.
2. Third-Party Attacks: Malicious code is injected through a third-party provider, also known as a supply chain attack. This is particularly concerning as modern websites rely on multiple third-party scripts to function, each of which can serve as an entry point for attackers.

How to Protect Against Digital Skimming

To safeguard your business from digital skimming, start by implementing these key measures:

1. Prevent Unauthorized Access: Use strong passwords, enforce unique logins, and ensure firewalls, encryption, and anti-virus tools are in place.
2. Regular Security Assessments: Conduct routine monitoring, third-party due diligence, and security audits to identify vulnerabilities.
3. Secure Code Practices: Follow secure coding standards and maintain compliance with security frameworks like PCI DSS.

New PCI DSS v4.0 Requirements

Recognizing the growing threat of digital skimming, the PCI Security Standards Council introduced two new requirements in PCI DSS v4.0, effective April 2025:

1. Requirement 6.4.3: Manage all JavaScript present on payment pages to minimize attack surfaces.
2. Requirement 11.6.1: Detect and alert on any tampering or unauthorized changes to payment pages.

Conclusion

Digital skimming is a rapidly growing threat, but businesses can protect themselves and their customers with the right tools and precautions. By staying informed, implementing strong security practices, and leveraging technologies, you can build a robust defense against this modern-day scourge.

The post Digital Skimming: The Growing Threat to Businesses in the Digital Era appeared first on .

With several new PCI DSS v4.0.1 requirements set to take effect on April 1, 2025, two requirements—4.2.1.1 and 12.3.3—have generated significant attention and questions. Let’s begin by reviewing the text of these requirements:

• 4.2.1.1:
  “An inventory of the entity’s trusted keys and certificates used to protect PAN during transmission is maintained.”
• 12.3.3:
  “Cryptographic cipher suites and protocols in use are documented and reviewed at least once every 12 months, including at least the following:
  • An up-to-date inventory of all cryptographic cipher suites and protocols in use, including the purpose and where used.
  • Active monitoring of industry trends regarding the continued viability of all cryptographic cipher suites and protocols in use.
  • Documentation of a plan to respond to anticipated changes in cryptographic vulnerabilities.”

The Relationship Between 4.2.1.1 and 12.3.3

Requirement 12.3.3 is a broad, comprehensive requirement encompassing all cryptographic use cases, including those covered under 4.2.1.1. While 4.2.1.1 focuses specifically on the inventory of trusted keys and certificates protecting PAN during transmission, 12.3.3 requires organizations to document and assess all cryptographic cipher suites and protocols used across their environments. This includes cryptographic implementations protecting cardholder data (CHD) and sensitive authentication data (SAD) in databases, files, or other locations.

The overarching goal of both requirements is to ensure organizations are cryptographically agile—capable of assessing and responding to cryptographic vulnerabilities or changes in standards without disruption. By proactively developing inventories and response plans, organizations can avoid being caught off guard when an algorithm or mode is deemed insecure or deprecated.

Recommendations for Implementing Requirements 4.2.1.1 and 12.3.3

1. Address Both Requirements Simultaneously
   Since 4.2.1.1 is a subset of 12.3.3, organizations should aim to fulfill both requirements concurrently. This approach streamlines documentation efforts and ensures all cryptographic assets are accounted for in a single process.
2. Inventory All Cryptographic Assets, Not Just PCI Scope
   Organizations often limit compliance efforts to systems within PCI scope. However, cryptographic agility is a security principle that extends beyond PCI compliance. Weak or outdated cryptography in non-PCI environments can still pose a risk to the organization, including its PCI environment. To maintain a strong security posture, a comprehensive inventory should include all cryptographic implementations, regardless of scope.
3. Focus on Cryptographic Inventories
   Developing a thorough inventory is critical for both requirements. For 4.2.1.1, this means cataloging all TLS certificates, including those used internally and externally. Many organizations overlook internally used secure communication protocols, such as:
   • TLS: Often associated with external communications, TLS is also widely used internally, such as with self-signed certificates for browser-based management tools or consoles. These certificates must be included in the inventory.
   • Secure Shell (SSH): Another commonly overlooked protocol, SSH usage must also be inventoried.

Cryptographic inventories should document:

• The algorithm and bit strength in use.
• The mode(s) of implementation.
• The specific locations and purposes for each cryptographic application.

A common pitfall is inadequate documentation for virtual private networks (VPNs). While organizations may know the VPN’s purpose and connections, they often lack details about the cryptographic algorithms and bit strengths used. This lack of information is typically due to outdated implementations or third-party-managed configurations. Regardless, all VPN cryptography must be documented, even for third-party-managed systems.

4. Understand Cryptography and Its Variations
   Not all cryptographic methods are equally secure. While detailed mathematical understanding isn’t necessary, security professionals should recognize that cryptographic strength varies widely. For instance:
   • The Advanced Encryption Standard (AES) is currently the strongest encryption standard endorsed by NIST. 128-bit, 192-bit, and 256-bit encryption are considered secure. Organizations should prioritize AES for encryption implementations.
   • Cryptography extends beyond encryption, including hashing functions, digital signatures, key derivation, and message authentication codes (MAC). While not all of these are covered under PCI DSS, they remain critical to a robust security strategy.

Organizations should reference NIST’s Special Publication 800-134Ar3 for guidance on transitioning to secure cryptographic algorithms and key lengths. This document outlines cryptographic best practices and deprecates insecure algorithms.

5. Prepare for Quantum Computing
   The advent of quantum computing underscores the urgency of cryptographic agility. Quantum computing has the potential to render many current cryptographic algorithms insecure. This is particularly concerning for organizations still relying on outdated algorithms like the Triple Data Encryption Algorithm (TDEA) or Secure Hash Algorithm 1 (SHA-1), which are already considered insecure.

   Organizations must proactively transition to quantum-resistant cryptography in line with NIST recommendations. Transition plans should account for end-of-life (EOL) deadlines and the complexities of replacing cryptographic implementations, such as third-party dependencies or rekeying large datasets.

Cryptographic Architecture and Active Monitoring

• Cryptographic Architecture
  A cryptographic architecture defines the organization’s approach to cryptography, including:
  • When and where cryptography is implemented.
  • The acceptable algorithms, modes, and methods (e.g., TLS, VPN, whole disk encryption, field/column encryption, etc.).
  • Guidelines for consistent implementation.

While a diagram may be helpful, a detailed written discussion of these elements is often more effective in defining cryptographic architecture.

• Active Monitoring of Cryptographic Trends
  To comply with the monitoring requirements of 12.3.3, organizations should maintain meeting minutes documenting discussions and decisions related to cryptographic trends and vulnerabilities. This includes:
  • Reviewing industry updates.
  • Assessing the impact of new vulnerabilities.
  • Planning transitions to secure algorithms.

Organizations must document clear transition plans for algorithms nearing EOL to prevent security gaps. Many commonly used algorithms are set to expire by 2030, so organizations should begin preparations immediately to ensure timely transitions.

In summary, PCI DSS v4.0.1 requirements 4.2.1.1 and 12.3.3 emphasize the need for organizations to maintain comprehensive cryptographic inventories, actively monitor industry trends, and ensure cryptographic agility. Organizations can mitigate risk and maintain compliance in an evolving threat landscape by adopting a proactive and comprehensive approach to cryptographic management.
