The Snowflake Drop Stage rule is designed to monitor and detect instances of DROP STAGE queries executed within a Snowflake account. This detection is particularly important due to its association with threat actor group UNC5537, which has been linked to potentially malicious activities. The rule operates by querying the Snowflake account usage table, specifically the query history, for DROP STAGE statements issued in the last two hours. This rule is necessary to prevent unauthorized data loss, as the DROP STAGE command can lead to data destruction, a tactic classified under impact techniques (T1485) in cybersecurity frameworks. Monitoring for such commands helps maintain security posture and ensure that critical data within Snowflake stages is not inadvertently or maliciously removed. The rule references additional documentation available on Snowflake's official websites to aid in further understanding and compliance.
