status: test
description: This rule flags Bitbucket audit events where a full data export is triggered. Full exports can be used by attackers to rapidly exfiltrate large volumes of repository and pipeline data, so distinguishing export activity from normal operations is important. It relies on Bitbucket audit log fields that record the export action under the data pipeline category.
