What it detects

This rule detects execution of python3 against /tmp/managed.pyz which is the primary payload dropped by the trojanized durabletask PyPI releases from the TeamPCP campaign. Running a zipapp from /tmp under python3 in this exact form indicates the supply-chain implant is active and harvesting cloud and Kubernetes credentials.
