Shai-Hulud is a supply chain worm, first reported in September 2025, that spreads through code repositories, including GitHub and NPM packages. It exploits CI/CD pipeline dependencies to propagate to victims and poisons the supply chain by publishing malicious packages. Once inside a victim environment, Shai-Hulud steals credentials and access tokens from compromised repository accounts and exfiltrates them to attacker-controlled servers via encoded GitHub Actions workflows.[1][2][3][4][5][6][7]
