Summary

A malicious PyTorch Lightning update (v2.6.3) on PyPI spread briefly, stealing credentials and raising major concerns about AI supply chain security. A malicious update of the PyTorch Lightning library exposed developers to credential theft and remote compromise. Attackers uploaded version 2.6.3 to the Python Package Index (PyPI), where it spread among developers before maintainers removed […]
