**Executive summary:** The TeamPCP campaign trojanized Microsoft DurableTask Python client packages (durabletask versions 1.4.1–1.4.3) on PyPI, delivering a rope.pyz payload that steals AWS/Azure/GCP/Kubernetes/Vault credentials, scrapes local password managers and shell history, and propagates via AWS Systems Manager and Kubernetes; PyPI quarantined the malicious versions and the report provides C2 domains, filesystem artifacts, and recommended detection and remediation steps.
