Earlier this year, a new feature was introduced to PyPI that allows administrators to quarantine projects deemed potentially harmful. This mechanism aims to prevent users from easily installing such projects and mitigating the risks associated with malware on the platform, which is a continuing issue. In the context of PyPI, there are distinct categories: Projects, Releases, and Files, with each having specific characteristics and relationships. Malware reports often pertain to entire Projects, as they usually operate under similar malicious themes. Typically, if a Project
