What it detects

This rule detects Snowflake sessions authenticating with client application strings tied to the UNC5537 data theft campaign such as the rapeflake FROSTBITE reconnaissance utility and the DBeaver_DBeaverUltimate client. UNC5537 abused stolen customer credentials to access Snowflake instances at scale for bulk data theft and extortion. Anomalous client applications on a control-plane login indicate credential abuse and unauthorized data access.
