Securing the open source supply chain across GitHub

Over the past year, there has been an increase in attacks on the open-source supply chain, particularly targeting secrets like API keys to publish malicious packages and propagate attacks across more projects. These attacks frequently begin by exploiting workflows on GitHub Actions. To combat this, GitHub recommends enabling CodeQL for security best practices, avoiding triggering workflows on pull_request_target, and pinning third-party Actions to full-length commit SHAs. In collaboration with OpenSSF, GitHub has implemented "trusted publishing" to remove secrets from build pipelines and improve package security across various repositories like npm, PyPI, and RubyGems. As part of ongoing efforts to enhance security, GitHub has accelerated the rollout of new capabilities in response to significant attacks such as Shai-Hulud, focusing on malware detection and community engagement to address potential backward incompatibilities. GitHub remains committed to strengthening open-source security and encourages community feedback as it advances its security roadmap for GitHub Actions and npm.
