What happened

A coordinated supply-chain campaign dubbed "Mini Shai-Hulud" has compromised numerous npm and PyPI packages in May 2026 by abusing compromised maintainer accounts and CI/CD workflows. Notable impacts include 300+ malicious versions published across AntV npm packages, 84 compromised @tanstack/* artifacts (via a GitHub Actions "Pwn Request", cache poisoning, and OIDC token extraction from runner memory), multiple malicious node-ipc releases, a Bun-based credential-stealer in the lightning PyPI package, and a suspected compromise of the Microsoft-associated durabletask PyPI package.
