Transfer stations fuel a growing LLM proxy economy
๐ Security researchers report a surge in proxy "transfer stations" used to hide origin of requests to frontier AI models, enabling credential abuse and model distillation. Team Cymru identified tens of thousands of relay servers running open-source platforms like CRS and sub2api that authenticate users with pooled stolen API keys and subscriptions. Activity links include China and Hong Kong, with many relays hosted on U.S. VPS providers, and evidence suggests heavy upload traffic consistent with extraction attempts. Organizations are advised to treat AI credentials as sensitive secrets, use short-lived tokens, monitor usage, and have playbooks to revoke compromised keys.
