Mini Shai-Hulud is a supply-chain campaign by TeamPCP that compromised popular packages across PyPI, NPM, and PHP (including Lightning 2.6.2/2.6.3, intercom-client 7.0.4/7.0.5, and intercom-php 5.0.2) to deploy an information-stealing payload that harvests credentials, keys, tokens, cloud secrets, and session tokens, actively scans Kubernetes and HashiCorp Vault, and exfiltrates data to GitHub repositories and the domain zero.masscan.cloud; the campaign impacted hundreds to thousands of developer repositories and leverages dynamic C2 fallback and downstream propagation via dependencies.
