Anthropic AI Flags Quick Vulnerabilities in Classified U.S. Systems

A U.S. official says Anthropic’s Mythos model identified vulnerabilities in highly classified government networks during a testing initiative with intelligence agencies (Project Glasswing). The vulnerabilities appeared within hours, though exploitation was not demonstrated in that period. The tests followed a federal directive to vet AI risks; Anthropic paused related models amid security-policy tensions with the administration. The NSA declined to comment, and cybersecurity leaders caution against broad restrictions while acknowledging the potential defense benefits of such tools.
