Snowflake, Inc.
The Snowflake, Inc., Data Security Breach litigation was centralized before Judge Brian Morris in the District of Montana in October 2024, consolidating claims arising from a 2024 incident in which attackers used stolen credentials to access customer data stored by numerous companies in Snowflake's cloud data-warehousing platform, particularly in environments that had not enabled additional authentication protections available on the platform. With 72 pending actions, this docket reflects the now-familiar cloud-platform-breach structure, where a shared technology platform's customers — themselves companies storing their own customers' data — become the vector through which many otherwise-unrelated individuals are affected.
A distinctive feature of this docket relative to some other vendor-breach litigation is the potential for a shared-responsibility dispute: because Snowflake made additional authentication protections available that some downstream customer companies had not enabled, resolution risk may turn partly on how responsibility is allocated between the platform provider and its downstream corporate customers, a question that can vary claim by claim depending on which specific downstream company's environment and security configuration is at issue.
Cloud-platform breaches of this kind are likely to remain a recurring pattern as more companies rely on shared cloud infrastructure to store customer data, and the shared-responsibility question raised here — platform-level security versus customer-configured security — is a structural issue likely to recur across future cloud-platform breach litigation as well. Criterica Intelligence's platform tracks this shared-responsibility dynamic across cloud-platform breach MDLs specifically, since it introduces an allocation-of-fault dimension not present in a single-defendant breach. A companion capital brief on this docket is available through Criterica Capital.
Attackers used stolen credentials to access customer data stored by numerous companies in Snowflake's cloud data-warehousing platform, particularly where additional authentication protections available on the platform had not been enabled.
Because Snowflake offered additional security protections that some downstream customer companies chose not to enable, raising questions about how liability should be allocated between the platform provider and its customers.
Likely, yes — as more companies rely on shared cloud infrastructure to store customer data, the platform-versus-customer-configuration question raised here is a structural issue expected to recur in future cloud-platform breach litigation.
It monitors the shared-responsibility allocation question specifically across cloud-platform breach MDLs, since it introduces a fault-allocation dimension not present in a typical single-defendant breach docket.
