The npm package @tanstack/eslint-plugin-start versions 0.0.4 and 0.0.7 have been compromised by the TeamPCP threat actor as part of the "Mini Shai-Hulud is back" worm. This malicious package steals credentials from the infected system and attempts to propagate itself to other accessible packages, maintaining persistence on the compromised computer. Systems with this package installed should be considered fully compromised, and all secrets and keys must be rotated from a different, clean system. Removing the package alone does not guarantee removal of all malicious components.
