maintainerPython Packaging Authority

setuptools is the foundational Python package build system, present in virtually every Python environment as a transitive dependency. It is used by pip to build packages from source and by projects that define `setup.py` or `pyproject.toml`. As a near-universal dependency, a compromise propagates to every package install step.

attack surface

Why this package is monitored

Build system packages run during every `pip install` invocation, including the install of all other packages in the environment. A compromised version can execute code at the point when environment variables, SSH agents, and cloud credentials are all active.

Attestd monitors setuptools using the following detection sources:

registry

Manually curated advisories in the Attestd registry, verified by a human analyst. Confidence 1.0.

osv

OSV.dev malicious-package advisories with IDs prefixed MAL-. Confidence 0.95.

pypi_yank

Versions yanked on PyPI with a security-related yanked_reason annotation. Confidence 0.80.
