Wired has identified SK Telecom as the South Korean telecom company whose access to Anthropic's Claude Mythos model the White House ordered revoked over alleged ties to China, days before the Trump administration imposed the export controls that pulled Anthropic's most advanced AI models offline.
SK Telecom, South Korea's largest wireless carrier, was among roughly 150 organizations added to Anthropic's Project Glasswing in early June, the program through which Anthropic distributes Mythos for vulnerability detection. The White House asked Anthropic to revoke the carrier's access shortly after that expansion, and the company complied immediately. No export controls were threatened at that point, according to Wired.
SK Telecom’s footprint in China is minimal, generating roughly $1.9 million in Chinese revenue in 2024 and employing seven people in the country, according to its annual report. The national-security concern attaches instead to its parent, SK Group, whose affiliates hold extensive interests in Chinese semiconductors, energy, and other sectors.
