TL;DR

SK Telecom was identified as the South Korean carrier involved in Anthropic’s Mythos model export restrictions. The White House ordered the revocation of its access over alleged ties to China, prompting ongoing negotiations to restore access.

SK Telecom has been officially identified as the South Korean telecommunications company whose access to Anthropic’s Mythos model was revoked by the White House in June 2024, amid security concerns related to alleged ties to China.

According to reports, SK Telecom was among approximately 150 organizations added to Anthropic’s Project Glasswing in early June, a program through which the AI company distributes Mythos for vulnerability detection. Shortly after this expansion, the White House requested that Anthropic revoke SK Telecom’s access, which the company complied with immediately. The decision was driven by national security concerns linked to SK Group’s broader interests in China, despite SK Telecom’s minimal direct footprint in the country.

SK Telecom’s involvement in China includes a joint venture with China Unicom called UNISK, established in 2004, and a residual investment of roughly $17 million. The company’s parent, SK Group, has extensive interests in Chinese semiconductors and energy sectors. Notably, SK hynix, a major memory chip supplier under SK Group, also received Mythos access, along with Samsung, both of which are key hardware providers for AI systems.

The US government’s move followed a separate dispute involving Amazon, Anthropic’s largest investor, which flagged a security vulnerability in the AI model Fable 5. Amazon CEO Andy Jassy reportedly raised concerns directly with officials, leading to the export controls that barred all foreign nationals from accessing Mythos and Fable 5, including SK Telecom. Anthropic responded by disabling the models globally, citing security risks and the potential halting of industry-wide AI deployment.

Implications of US Security Measures on South Korean Tech

This development highlights the increasing scrutiny of international tech companies involved in AI and the potential impact of US security policies on South Korean firms like SK Telecom. The incident underscores broader concerns about foreign influence and security risks in the rapidly evolving AI landscape, which could influence global supply chains and international cooperation in AI development.

For SK Telecom, the incident may affect its reputation and future collaborations, especially as it seeks to expand its AI capabilities and partnerships in South Korea and abroad. The situation also raises questions about the transparency of US export controls and their implications for international technology trade.

Background on SK Telecom’s Chinese Ties and AI Involvement

SK Telecom, South Korea’s largest wireless carrier, has a history of engagement in China, including a joint venture with China Unicom called UNISK and investments in Chinese telecom infrastructure. Despite a relatively small direct revenue from China in 2024, the company’s broader interests through SK Group include significant stakes in Chinese semiconductors and energy sectors. These connections have drawn attention amid US security concerns about foreign influence in AI technology.

Anthropic’s Mythos models, including Mythos 5, are advanced AI systems used for vulnerability detection and cybersecurity applications. The models have gained industry attention for their capabilities, but recent security incidents and political concerns have led to export restrictions, affecting their deployment and access globally.

The incident involving SK Telecom follows similar restrictions placed on other major AI hardware suppliers like Samsung and SK hynix, reflecting a broader geopolitical context influencing AI development and international cooperation.

“The revocation of SK Telecom’s access appears linked to broader security concerns rather than direct involvement in malicious activities.”
