Summary

WIRED reports that alleged ties between South Korean telecom giant SK Telecom and China triggered a crisis for Anthropic, leading to the shutdown of its AI models Claude Mythos and Fable 5. US officials became concerned over SK Telecom's access to Mythos via Project Glasswing, prompting the White House to order Anthropic to cut access, which the company immediately did. SK Telecom denied any China connections, despite its broader SK Group having significant business interests in China and a past stake in China Unicom. This incident, combined with Amazon and other companies flagging security flaws in Fable 5 that could bypass safety restrictions, caused the White House to lose confidence in Anthropic, forcing both models completely offline for all global customers.

Key takeaway

For tech executives overseeing AI partnerships and model deployment, this incident underscores critical risks. Your organization must prioritize thorough due diligence on international partners to identify potential geopolitical entanglements. Simultaneously, implement robust, continuous security audits for all AI models. Failing to address these areas can result in immediate, government-mandated product shutdowns, severely impacting your market presence and customer trust.
