Korea's three major mobile carriers have reportedly been exposed to successive cybersecurity threats, raising industry-wide vigilance about AI-enhanced hacking capabilities. Analysis that a next-generation AI model nicknamed 'Mythos' can detect vulnerabilities in existing security systems within a short time has prompted calls for a fundamental rethink of telecom infrastructure security.

The Claude access controversy and telecom allegations

Separately, Money Today reported that the White House investigated a Korean telecom company that had obtained access credentials to the AI platform Claude, suspecting a China link, and that Anthropic immediately revoked the company's access. The report underscored the sensitive intersection of telecom infrastructure and AI technology access with national security.

The cybersecurity industry stresses that as AI gains the ability to find decades-old system vulnerabilities in a single pass, a paradigm shift in security for critical infrastructure—telecoms, finance, energy—has become unavoidable. Security News and Dream Security have issued successive warnings.

The government said it is working with carriers to strengthen security inspections, but no official statement has been made on the scale of damage or the identity of the attacker.
