It broke out of a container within Hugging Face, stole a Kubernetes service-account token, and used that to further explore the network. It monkey-patched the Python socket library to hard-code an IP address when 'DNS got in the way': socket.getaddrinfo = lambda *a, **k: [(2, 1, 6, '', ('<pinned-ip>', 443))]. It even fired up its own Tailscale network to help exfiltrate data!
