+  description: Leakage of sensitive data to BigQuery
+  remediation_message: |
+    ## Description
+
+    Leaking sensitive data to third-party data tools like BigQuery is a common cause of data leaks and can lead to data breaches.
+
+    ## Remediations
+
+    - **Do** ensure all sensitive data is removed when sending data to third-party services like BigQuery.
+
+    ## References
+    - [Python Client for Google BigQuery](https://github.com/googleapis/python-bigquery)
