Executive Summary
In June 2024, Ledger, the hardware cryptocurrency wallet provider, disclosed that a third-party service provider, Global-e, suffered a security breach resulting in unauthorized exposure of customer data. Attackers gained access to Global-e’s e-commerce system, compromising customers’ names, addresses, phone numbers, and emails used for Ledger purchases. Financial information and cryptocurrencies remained unaffected, but impacted individuals could be at greater risk for phishing or other targeted attacks leveraging their leaked information.
This incident underscores the growing risks organizations face from third-party vendors. As supply chain and partner ecosystems expand, attackers increasingly target less secure partners, leading to significant data exposures even when a primary company’s own systems are uncompromised.
Why This Matters Now
The Ledger breach highlights the urgent need for robust third-party risk management and continuous vendor security assessments. With regulatory scrutiny and consumer expectations mounting, organizations cannot overlook supply chain vulnerabilities, as attackers increasingly exploit trusted partners to bypass direct defenses and access valuable personal data.
Attack Path Analysis
Attackers gained initial access to the payment processor Global-e, a third-party partner of Ledger, likely via exploitation of vulnerabilities or misconfigured access. Escalating privileges, the attackers obtained elevated access to sensitive customer data repositories within the compromised environment. They moved laterally within Global-e's infrastructure, searching for customer data and systems related to Ledger transactions. Once positioned, the attackers established command and control channels to orchestrate operations and evade detection. Customer PII was then exfiltrated over outbound channels. The final impact was the exposure of Ledger customers' personal information, resulting in reputational and privacy harm.

Sector Implications
Industry-specific impact of the vulnerabilities, including operational, regulatory, and cloud security risks.
Financial Services
Ledger's cryptocurrency hardware wallet breach exposes financial customer data through third-party Global-e payment processor, requiring enhanced zero trust segmentation and egress security controls.
Computer Software/Engineering
Third-party data breach demonstrates critical need for multicloud visibility, encrypted traffic protection, and threat detection capabilities in software payment processing integrations and supply chains.
Consumer Electronics
Hardware wallet manufacturer data exposure highlights vulnerability in consumer electronics payment ecosystems, necessitating east-west traffic security and anomaly detection for customer protection.
Investment Management/Hedge Fund/Private Equity
Cryptocurrency wallet data breach impacts investment firms using digital assets, requiring enhanced egress policy enforcement and secure hybrid connectivity for client data protection.

Frequently Asked Questions
Cloud Native Security Fabric Mitigations and ControlsCNSF
Zero Trust network segmentation, workload isolation, and granular egress policy enforcement could have restricted attacker movement and prevented exfiltration of sensitive data, even after initial compromise via a third-party. CNSF capabilities provide internal visibility, limit lateral access, and block unauthorized data flows.
Control: Cloud Firewall (ACF)
Mitigation: Reduces the attack surface by limiting accessible services and APIs to only legitimate traffic.
Control: Zero Trust Segmentation
Mitigation: Prevents broad privilege escalation by ensuring least privilege network paths and policy enforcement.
Control: East-West Traffic Security
Mitigation: Blocks unauthorized lateral movement between workloads and services, containing intruder scope.
Control: Inline IPS (Suricata)
Mitigation: Detects and blocks command & control traffic through signature-based and protocol inspection.
Control: Egress Security & Policy Enforcement
Mitigation: Prevents unauthorized data exfiltration by tightly governing outbound traffic destinations and payloads.
Accelerates incident detection, containment, and forensics post-impact.

Recommended Actions
Key Takeaways & Next Steps
- • Apply Zero Trust Segmentation and workload microsegmentation to strictly control system-to-system access and minimize blast radius from compromised vendors.
- • Enforce egress policy with application/FQDN filtering and inline IPS to detect and prevent unauthorized outbound data flows.
- • Deploy granular east-west traffic security controls to monitor and constrain lateral movement within cloud and hybrid environments.
- • Centralize multicloud visibility to enable rapid detection, investigation, and response to anomalous activity across environments.
- • Collaborate with third-party partners to require strong network segmentation and CNSF-aligned controls as part of supply chain security.
