It was January 15, 2024, and the preliminary findings from workpaper WP-GPC-INC-001-A were grim: an over-privileged Terraform service principal, operating within GlobalPay's hybrid cloud environment, had inadvertently provisioned an unencrypted AWS S3 bucket and an Azure Blob storage container. This misconfiguration, active for nearly 90 days, exposed sensitive cross-border financial telemetry, impacting an estimated 1.2 million transactions valued at over $2.3 billion. The breach, discovered by an external threat intelligence feed, triggered immediate notification requirements under SEC Cybersecurity Rules and DORA, with potential fines exceeding $15 million and remediation costs already topping $5 million. Our mandate: conduct a Phase I audit focused on the shared responsibility model and Zero Trust Architecture, specifically identifying where GlobalPay's Complementary User Entity Controls (CUECs) failed to prevent this catastrophic data exposure.
