How PCI DSS 4.0 Exposes API Security Flaws — and What to Do About It
The countdown for PCI DSS 4.0 has already begun. With the new security standard for payment environments coming into effect, companies that process, store, or transmit card data face a new urgency: protect exposed APIs from fraud, automated abuse, and bot attacks.
The infographic by Cequence, distributed by Nova8, reveals alarming data about the vulnerabilities exploited by digital criminals in APIs and shows what security leaders must do to ensure real compliance and effective protection.
APIs: The Weakest Link in PCI DSS 4.0 Compliance
With more than 800 APIs on average per organization, most companies lack sufficient visibility to identify vulnerabilities before they are exploited.
Among the main risks highlighted in the document are:
- Credential Stuffing Attacks
- Account Takeovers (ATOs), with over 300 million attempts blocked
- Abuse of loyalty programs and price scraping by bots
- Credit check fraud and shopping cart abuse
These attacks exploit unprotected API endpoints, which go unnoticed by traditional solutions like WAFs or MFA.
What PCI DSS 4.0 Requires — and How APIs Impact This
The new PCI DSS 4.0 standard requires more granular controls, such as:
- Mandatory encryption of the PAN (account number)
- Inventory and documentation of all internal, external, and third-party APIs
- Continuous monitoring and testing of APIs in production and pre-production
- Use of automated tools for threat detection and response
- Change control in components and code updates in APIs
These requirements go beyond the traditional “compliance checklist” and demand modern and automated API Security platforms, like the Cequence solution.
