Anthropic says it cut Claude reasoning token theft by up to 99% in fight against industrial-scale distillation

Anthropic disclosed a major defensive win against coordinated model distillation attacks targeting Claude's reasoning tokens. The scale and attribution matter: this confirms a known threat vector is operationalized at industrial volume by named Chinese labs, and Anthropic's countermeasures—account bans and technical hardening—are measurable. Practitioners running Claude in enterprise environments need to understand the attack surface; the distillation risk affects cost and model-moat strategy.
