These attacks exploit trust in third-party scripts, injecting malicious code that silently exfiltrates cardholder data without the merchant's knowledge. The core failure in most breaches is the absence of visibility: merchants often have no idea what scripts are running, where they originate, or when they change. This matters because even one compromised third-party dependency can expose every customer who visits a checkout page. Compliance is now a forcing function for supply chain script hygiene that should have been standard practice long ago.","**Immediate actions:**\n- Conduct a full inventory of all scripts loaded on checkout pages, including first- and third-party sources.\n- Implement a Content Security Policy (CSP) header to restrict which script sources are permitted to execute.\n- Review and revoke authorization for any unrecognized or unnecessary scripts currently active on payment pages.\n\n**Long-term improvements:**\n- Establish a formal script authorization and change-management process requiring approval before any new script is added to checkout flows.\n- Deploy a continuous script monitoring solution (e.g., Reflectiz, Source Defense) to detect behavioral changes or unauthorized script additions in real time.\n- Integrate third-party vendor risk assessments into your procurement process to evaluate the security posture of all script providers.\n\n**Detection & audit measures:**\n- Configure alerting for any runtime changes to scripts on payment pages, including new domains, new script hashes, or unexpected network calls.\n- Maintain tamper-evident audit logs of script inventory reviews to provide auditable evidence for PCI DSS assessors.\n- Schedule quarterly script reviews and reconcile against an approved baseline inventory.",[12,13,14,15,16,17,18,19,20],"PCI DSS v4.0.1 Requirement 6.4.3 (Script Inventory & Authorization)","PCI DSS v4.0.1 Requirement 11.6.1 (Tamper Detection Mechanism)","CIS Control 2: Inventory and Control of Software Assets","CIS Control 13: Network Monitoring and Defense","NIST SP 800-53 CM-7: Least Functionality","NIST SP 800-53 SI-7: Software, Firmware, and Information Integrity","NIST Cybersecurity Framework DE.CM-4: Malicious Code Detection","GDPR Article 32: Security of Processing (for EU merchant applicability)","OWASP Top 10 A08:2021 – Software and Data Integrity Failures","published","2026-06-18T12:20:34.467411+00:00","2026-06-18T12:20:34.375+00:00",{"id":7,"url":25,"title":26},"https:\u002F\u002Fthehackernews.com\u002F2026\u002F06\u002Fthe-scripts-on-your-checkout-page-are.html","The Scripts on Your Checkout Page Are Now a PCI DSS Problem",[28,34,40],{"id":29,"name":30,"slug":31,"description":32,"color":33},"1732a005-556e-411c-a9db-5edec3058571","Logging & Monitoring","logging-monitoring","Missing logs, no alerting, blind spots","#a855f7",{"id":35,"name":36,"slug":37,"description":38,"color":39},"c0dcc566-3654-4d70-8ede-262a198e732f","Regulatory Compliance","regulatory-compliance","GDPR, NIS2, DORA, sector-specific violations","#ec4899",{"id":41,"name":42,"slug":43,"description":44,"color":45},"f0c2a0af-58aa-4128-87c9-6acd30f2dc48","Supply Chain","supply-chain","Third-party risk, compromised dependencies","#8b5cf6"]
