Mass GitHub Compromise: How Stolen Developer Credentials Enable Supply Chain Attacks

This campaign reveals a critical threat convergence: infostealers harvesting developer credentials now directly fuel supply chain attacks through GitHub, affecting thousands of repositories at scale. The attackers' exploitation of CI/CD workflows to extract AWS keys, GCP tokens, and SSH credentials transforms personal endpoint vulnerabilities into enterprise-wide infrastructure compromise. Organizations face an urgent security imperative as endpoint threats on developer machines now pose direct supply chain risks to entire cloud environments.
