Executive Summary
In September 2023, Nissan Motor Co. Ltd. confirmed that the personal information of thousands of its customers was compromised due to a supply chain data breach at Red Hat, a leading software vendor. The breach stemmed from unauthorized access to customer data managed by Red Hat, which affected Nissan’s customer records, including names and contact information. While there is no current evidence of financial or highly sensitive information being lost, Nissan has notified the individuals impacted and is working with Red Hat to further assess and contain the breach’s full scope.
This incident highlights the ongoing risk posed by third-party vendors in the automotive and technology sectors, as organizations increasingly rely on external service providers for software and infrastructure. The Nissan-Red Hat breach underscores the rising threats targeting supply chains, emphasizing the urgent need for robust vendor security controls and visibility into partner ecosystems.
Why This Matters Now
Supply chain attacks are becoming more frequent and sophisticated, targeting trusted vendors to compromise downstream organizations. As companies strengthen their internal controls, adversaries are shifting focus to third parties, making vendor risk management and due diligence critical to safeguarding customer data and business operations.
Attack Path Analysis
Adversaries initially compromised Red Hat’s environment via a supply chain breach, likely exploiting trust or integration between software vendors. Upon gaining foothold, they escalated privileges within Red Hat’s cloud or SaaS footprint. Using their elevated access, the attackers moved laterally through interconnected cloud workloads and services. Establishing outbound command and control, they communicated with external infrastructure to coordinate and persist activity. Sensitive customer data was then exfiltrated from Red Hat’s systems. The impact manifested as exposure of thousands of Nissan customer records, putting individuals and the organization at risk.

Frequently Asked Questions
Cloud Native Security Fabric Mitigations and ControlsCNSF
Zero Trust segmentation, east-west traffic controls, centralized visibility, and egress policy enforcement would significantly have reduced the attacker’s ability to move laterally, exfiltrate data, and operate unobserved across multi-cloud supply chains.
Control: Cloud Native Security Fabric (CNSF)
Mitigation: Limits unauthorized access via inline enforcement and broad integration visibility.
Control: Zero Trust Segmentation
Mitigation: Restricts privilege expansion by enforcing workload and identity segmentation.
Control: East-West Traffic Security
Mitigation: Prevents unauthorized movement between cloud workloads and namespaces.
Control: Egress Security & Policy Enforcement
Mitigation: Detects and blocks unauthorized outbound communications.
Control: Multicloud Visibility & Control
Mitigation: Exposes and alerts on atypical data transfers leaving the cloud.
Protects sensitive data during any transfer, reducing exposure risk.

Recommended Actions
Key Takeaways & Next Steps
- • Adopt zero trust segmentation and east-west traffic security to prevent lateral movement by attackers post-intrusion.
- • Enforce granular egress controls with threat-aware filtering to detect and block malicious outbound communications and exfiltration attempts.
- • Implement centralized multicloud visibility to rapidly identify anomalous intra- and inter-cloud data flows.
- • Maintain strong real-time inline inspection at all cloud ingress, egress, and workload interaction points with CNSF and IPS technologies.
- • Mandate workload-to-workload and service-to-service encryption to ensure in-transit data confidentiality, mitigating the impact of any data theft.
