The April 2026 release of Anthropic’s Claude Mythos Preview marked a pivotal moment in cybersecurity. This frontier AI model autonomously identified thousands of previously unknown zero-day vulnerabilities across major operating systems, web browsers, and foundational software libraries. In response, Anthropic launched Project Glasswing, a restricted-access defensive program partnering with global tech and finance leaders. This paper synthesizes the technical, philosophical, and geopolitical implications of Mythos, with reference to the high-level emergency meeting convened by India’s Finance Minister Nirmala Sitharaman with banks on 23 April 2026.
It explores why nation-states and sophisticated hackers had not previously uncovered these flaws at scale, examines hypothetical misuse scenarios, and highlights a critical limitation: even Mythos cannot identify all zero-days, leaving residual risks in an accelerating AI-driven arms race.
