Disrupting Supply Chain Attacks on npm and GitHub Actions

GitHub describes a recurring pattern of supply-chain attacks against npm and CI/CD systems over the past year. Attackers combine weaknesses in package repositories and automation workflows to distribute malware across hundreds of open-source projects, while stealing credentials for further propagation or later exploitation. The post outlines security changes already implemented across npm and GitHub Actions, framed as targeted disruption of high-impact links in the attack chain rather than reliance on a single defensive capability.
