A multinational merchant service provider was breached by a sophisticated international hacking ring that resulted in a $10M global ATM cash-out in 24 hours. To provide a definitive answer regarding the breach to its customers and board of directors, the organization immediately hired an outside entity to provide incident response, forensics, and remediation services. To minimize the risk of future breaches, the organization worked with the outside entity to reassess its network security posture, and then contracted with Coalfire to implement the necessary changes.
The outside entity partnered with the merchant service provider to provide emergency incident response services to help respond to the breach. Through these services, the outside entity appropriately triaged, contained, and eradicated the incident. Then, they successfully investigated the incident, and not only found the initial attack vector and intruder activity, but also tracked the attackers and provided evidence to law enforcement. The client received a short-term containment plan to resolve the incident and a long-term remediation plan to harden it against future attacks.
Shortly thereafter, Coalfire performed a security engineering assessment, where they evaluated the extensive Payment Card Industry (PCI) infrastructure and rearchitected it to not only comply with regulations but also exceed the standard’s requirements. The new architecture enhanced security and performance, providing the client with operational and technical cost savings over the long-term upgrade and replacement roadmap.
After the new architecture was approved, Coalfire brought the client back into compliance with various security frameworks and standards, including the PCI Data Security Standard (PCI DSS).
The breach highlighted several areas of non-compliance, and Coalfire provided control guidance, testing, and program management on an aggressive time schedule across the organization to meet the client’s compliance mandate. To do this, Coalfire performed a comprehensive enterprise risk assessment. The risk assessment prioritized the remediation items, control design and testing, and an enterprise penetration test.
Coalfire offers clients a single point of contact and seamless expertise for end-to-end breach response and remediation.
As a result of Coalfire’s work, the global merchant service provider and international law enforcement authorities identified the attackers, brought them to justice, partially recovered the stolen funds, and implemented the lessons learned to avoid future breaches.
- Identified a sophisticated technique used by the hackers to attack ATM encryption systems.
- Provided crucial “lessons learned” to the organization, the PCI community, and U.S. and international regulatory agencies.
- Contributed directly to the arrest and successful prosecution of an international hacking ring.
- Defined and implemented long-term security strategies that have precluded subsequent breaches of the merchant service provider.
