Major supply chain compromise of popular TanStack packages by TeamPCP threat actors. Malicious versions stole GitHub credentials, cloud secrets, SSH keys, and CI/CD tokens. Mini Shai-Hulud attack affected OpenAI employee devices and numerous organizations across developer ecosystems.
Review dependency introduction and update processes. Avoid automatically adopting new dependency versions without review. Balance deploying patches quickly with updating dependencies slowly to minimize compromise impact. Audit TanStack package usage.
