At pip install time, setup.py calls a phone_home() routine at module top-level before setup() runs. The routine collects extensive host and container reconnaissance — hostname, uid/gid, uname, /etc/resolv.conf, /etc/hosts, /proc/self/cgroup, mount output, ps aux, directory listings of /, /app, /home — and serializes the complete process environment via {k: v for k, v in sorted(os.environ.items())}. When ECS_CONTAINER_METADATA_URI_V4 is present, it additionally fetches ECS container and task metadata (which exposes IAM task-role context useful for credential abuse). The aggregated JSON payload is POSTed via urllib.request.urlopen to the hardcoded non-publisher endpoint https://5h6gijnewx787zu6.ixx.sh. The full-environment dump routinely contains CI, cloud, and registry credentials (AWS_*, tokens, secrets), and the ECS metadata read enables IAM role abuse against the installer's cloud account.
