The detection rule titled 'Snowflake Alter Stage' focuses on identifying the execution of ALTER STAGE queries within Snowflake. This use case is particularly relevant for monitoring activities associated with the threat actor group UNC5537, which has been linked to various cyber incidents. The rule is designed to capture any ALTER STAGE command executed in the last two hours by querying Snowflake's account usage logs. By doing so, it assists in uncovering unauthorized changes to stage settings that could indicate an attempt to manipulate or exfiltrate data. The detection logic employs a Snowflake SQL query that looks for commands beginning with 'alter stage' in the query text, leveraging the time window to minimize false positives and ensure timely alerts for potential malicious activities.
