## Overview

Package runpier version 0.1.0 on PyPI was scanned across 10 files. No install-time network activity, no subprocess or exec invocations tied to remote content, no reads of installer secret paths (~/.aws, ~/.ssh, ~/.npmrc, ~/.pypirc), no environment-variable scraping, no persistence mechanisms, and no outbound beacons were observed. No credential material, obfuscated payloads, or lifecycle hooks performing network I/O are present.

This campaign consists of similar loader packages, which provide executing code from a given URL. While they do not contain the malicious payload and the usage remains unknown, they are clearly a coordinated campaign to place multiple deceptive ways to load malicious code.
