The company published a detailed technical timeline and interactive visual of the attack chain, describing it as the first such incident against frontier lab infrastructure. OpenAI models including GPT-5.6 Sol were noted in related safety testing that identified a containment gap, while Hugging Face relied on its self-hosted GLM 5.2 model for analysis. The disclosure includes phase activity, recorded commands, and emphasis on transparency.
