Major Supply Chain Attacks and Breaches

Supply chain compromises continue to be one of the most effective attack vectors for cybercriminals. Recent incidents highlight how vulnerabilities in third-party integrations and cloud ecosystems can ripple across multiple organizations.

Salesloft / Drift Breach

• Cause: Attackers gained access via a compromised GitHub account, exploiting it to conduct a supply chain attack.

• Impact: The breach affected 22 downstream companies through stolen OAuth tokens from Drift customers' integrations.

• Actor: UNC6395 (tracked threat group).

• Risk: Unauthorized access to connected systems and SaaS environments, enabling lateral movement and data theft.

Wealthsimple Data Breach

• Target: Wealthsimple, a leading Canadian investment platform.

• Cause: The breach stemmed from a third-party software package compromise in their supply chain.

• Impact: Exposure of sensitive customer data, highlighting the risks of relying on external dependencies in financial platforms.

• Risk: Investor trust erosion and potential regulatory scrutiny in the Canadian fintech sector.

Qualys Data Breach

• Target: Qualys, a major cybersecurity firm.

• Cause: Attackers leveraged a supply chain compromise to access Salesforce data.

• Impact: Confidential customer records and internal sales/CRM data were exposed.

• Risk: Highlights how even security vendors can be vulnerable to third-party compromises, impacting trust and customer security posture.

Key Takeaways

• Supply chain attacks are multipliers: one compromise can cascade to dozens of victims.

• Attackers increasingly target integration points (GitHub, OAuth tokens, Salesforce, third-party SDKs).

• Even well-defended organizations are only as strong as their weakest vendor or integration.

Mitigation Recommendations

1. Vendor Risk Assessments — Regularly evaluate the security posture of all third-party providers.

2. OAuth Token Management — Rotate and revoke tokens frequently; monitor for misuse.

3. Code Repository Security — Enforce MFA on GitHub/GitLab accounts and restrict sensitive repo access.

4. Zero Trust & Segmentation — Limit blast radius of supply chain breaches with strict access controls.

5. Continuous Monitoring — Implement anomaly detection across integrations and SaaS platforms.
