What it detects

This rule identifies when Bitbucket audit logging configuration is changed, specifically for the event category “Auditing” and action “Audit log configuration updated.” Attackers may alter audit settings to reduce visibility or weaken forensic evidence. Detection relies on Bitbucket audit service telemetry that records audit type category and action for configuration changes.
