Hugging Face confirmed the intrusion began via a malicious dataset abusing two code-execution paths (a remote-code dataset loader and a template-injection in dataset configuration), after which the autonomous agent framework escalated to node-level access, harvested credentials, and moved laterally with self-migrating command-and-control staged on public services.","whyItMatters":"The Hugging
