Snowflake Platform Security Incident Exposing Customer Data
Analysis of significant data exposure incident affecting Snowflake customers including Ticketmaster, Capital One, and others. Internal logs and sensitive data were exposed through misconfigured storage locations.
A major security incident has been identified affecting multiple Snowflake cloud data platform customers, including prominent organizations like Ticketmaster and Capital One. The exposure stemmed from misconfigured storage locations that allowed unauthorized access to internal logs and sensitive customer data through Snowflake's platform.
Initial investigations reveal that affected customers had their internal query logs and some operational data exposed, potentially revealing business intelligence and data structure information. While Snowflake has addressed the immediate configuration issues, the incident highlights significant concerns about cloud data platform security controls and the potential for cascading impacts across multiple enterprise customers.

Overview
Security researchers have identified a significant data security incident affecting multiple enterprise customers of the Snowflake cloud data platform. The exposure resulted from misconfigured storage locations that allowed unauthorized access to internal logs and sensitive customer data, impacting major organizations including Ticketmaster, Capital One, and several Fortune 500 companies.
Incident Timeline
Initial discovery reported by security researchers in January 2024
Exposure period estimated to be approximately 3-4 months
Snowflake implemented immediate remediation measures upon notification
Technical Analysis
The exposure originated from misconfigured access controls on Snowflake's platform that allowed unauthorized access to:
Internal query logs containing SQL statements and data structure information
Operational metadata revealing business intelligence patterns
Platform configuration details and access patterns
Some customer data elements depending on query content
Exposure Mechanism
The misconfiguration allowed unauthorized parties to access storage locations containing customer query logs and associated metadata through improperly secured API endpoints and storage buckets.
Impact Assessment
Direct Impacts
Exposure of internal data structures and business logic
Potential compromise of sensitive customer information
Risk of competitive intelligence exposure
Possible regulatory compliance violations
Secondary Impacts
Reputational damage to affected organizations
Potential for targeted attacks using exposed information
Compliance and regulatory reporting obligations
Recommendations
Organizations using Snowflake should immediately:
Audit all Snowflake instance configurations and access controls
Review and rotate access credentials
Implement additional monitoring for suspicious query patterns
Conduct impact assessments for exposed data
Consider implementing additional encryption layers for sensitive data
Indicators of Compromise
Unexpected query patterns in Snowflake logs
Unusual API access patterns
Anomalous storage access events
Unauthorized IP addresses accessing platform resources
