How to Ensure Open Source Packages Are Not Landmines

CISA and OpenSSF introduced the "Principles for Package Repository Security" to harden open source ecosystems by urging controls such as MFA for maintainers, third-party reporting mechanisms, warnings for outdated or insecure packages, and adoption of provenance tools like Sigstore. The guidance targets threats like namesquatting and malicious uploads across repositories (e.g., GitHub, PyPI, NPM, Maven) amid reports of rising intentionally malicious components and a recent twofold increase in malicious packages affecting development environments.
