Snowflake Data Breach Exposes Records of Over 100 Million Individuals
What Happened — A former Snowflake employee, Connor Riley Moucka, pleaded guilty to computer fraud, wire fraud, aggravated identity theft and conspiracy for a 2024 intrusion campaign that compromised at least 165 Snowflake‑customer accounts and exposed personal data belonging to roughly 100 million people.
Why It Matters for Compliance & Audit Readiness
- The incident underscores the need for robust SOC 2 access‑control policies (e.g., least‑privilege, MFA, session monitoring) that can detect and prevent unauthorized use of privileged accounts.
- Continuous evidence collection around privileged‑access reviews and anomalous‑login alerts provides the audit‑ready trail SOC 2 auditors expect after a breach.
Who Is Affected — SaaS/cloud‑data‑warehouse providers, their downstream customers (financial services, health‑tech, retail, etc.), and any organization that stores sensitive PII in Snowflake.
Recommended Actions
- Map the intrusion to SOC 2 CC6.1 (Logical Access) and CC6.2 (User Access Management) controls; verify that MFA, password policies, and privileged‑access reviews are enforced.
- Pull and archive login‑activity logs for the affected period as audit evidence; implement continuous monitoring alerts for anomalous credential use.
- Conduct a third‑party risk review of Snowflake’s own SOC 2 attestations and any sub‑processor agreements.
