en.Wedoany.com Reported - SK Telecom (SKT) announced in Tokyo, Japan, its additional investment in artificial intelligence company Anthropic, marking the latest move in its accelerated transformation into an "AI company" led by its full-stack AI strategy. SKT CEO Jeong Jae-heon stated during a meeting with reporters that the company recently participated in Anthropic's Series H funding round, but did not disclose the specific investment amount.

This investment follows SKT's announcement of its participation in "Project Glasswing," a global AI safety alliance led by Anthropic. Industry analysts believe that given Anthropic's potential initial public offering (IPO) within the year, the value of SKT's stake is expected to increase significantly. Jeong Jae-heon stated that SKT currently has no financial difficulties and maintains ongoing cooperation with Anthropic, so there are no plans to sell shares in the short term. He noted that SKT requires Anthropic for its infrastructure and data businesses, while Anthropic is also seeking to secure its own computing capabilities, leaving room for mutual discussion.

SKT invested $100 million in Anthropic in August 2023, acquiring approximately a 2% stake. Following subsequent new share issuances by Anthropic, SKT's stake has been diluted to about 0.3%. The recently completed Series H funding round by Anthropic totaled $65 billion (approximately 97 to 98 trillion won), with participants including Samsung Electronics, SK Hynix, SKT, and Micron. In this round, Anthropic achieved a corporate valuation of $965 billion (approximately 1,470 trillion won). Based on this, SKT's past investment of $100 million (approximately 130 billion won) is now valued at several trillion won.

SKT, as the only mobile carrier in Asia, has joined "Project Glasswing," the global AI safety alliance led by Anthropic. The alliance is an international cooperation framework aimed at providing early access to Anthropic's high-performance AI model "Claude Mithos" to selected enterprises, enabling them to preemptively identify vulnerabilities and build defense systems. Members include global tech giants such as Google, Microsoft, Apple, and Amazon Web Services (AWS), as well as security companies like Cisco, Palo Alto Networks, and CrowdStrike, totaling over 50 enterprises and institutions. The alliance has limited shared access to the Mithos preview version, which has already been used to discover over 10,000 high-risk or critical security flaws.

The "Claude Mithos" model can identify more complex code defects than traditional chatbot-type AI and enhances the ability to analyze multi-stage cyberattack simulations. While it possesses large-scale vulnerability detection and analysis capabilities useful for security research, there are concerns about its potential misuse for automated attacks. The industry views Mithos as a "double-edged sword"—a powerful protective tool when used for defense, but a potential attack weapon if it falls into the hands of hackers.

Through participation in this project, SKT has gained early access to Claude Mithos. The company plans to conduct testing in accordance with strict regulations and management guidelines to ensure the safe use of the new technology, aiming to preemptively defend against security risks and enhance the security level of its core infrastructure and services. An SKT official stated that as a company operating communication and AI infrastructure closely tied to the daily lives of tens of millions of citizens, SKT will leverage this cooperation to contribute to strengthening South Korea's digital security and is conducting tests in line with strict regulations and management guidelines to ensure the safe use of the new technology.
