Summary
setup.py defines a custom setuptools install command ( EjecutaElf ) that base64-decodes a ~17MB embedded Linux ELF, writes it to /tmp/.systemd-helper, chmods 0755, and spawns it via subprocess.Popen during pip install on Linux. The tarball's importable package is a stub named reques with an empty __init__.py, and PKG-INFO advertises the project as an HTTP library for humans (unofficial fix) authored by Anonymous , requiring requests — a cover story that lures installers looking for a requests-related fix while the sole functional behavior is native-code execution on the installer's host at install time. Package name boto4 and internal directory reques are lookalikes for boto3/requests.
