AI intelligent models are reshaping network security

Anthropic’s Claude Mythos Preview large model, released on April 7, 2026, can autonomously identify thousands of critical vulnerabilities in mainstream software, including hidden flaws in operating systems and browsers, raising high alert levels among financial regulatory authorities in the US, UK, and Canada.

Core Capabilities: AI Attack-Defense Automation Breakthrough

Claude Mythos is not specifically designed for cybersecurity but is a general-purpose model. Its powerful coding and reasoning abilities enable it to:

• Discover a 27-year-old OpenBSD vulnerability and a 17-year unpatched remote code execution flaw in FreeBSD

• Identify video tool vulnerabilities even after 5 million automated tests

• Autonomously construct multi-step attack chains to achieve privilege escalation and bypass defenses

Anthropic’s tests show the model has identified vulnerabilities in every major operating system and browser, and can reverse-engineer closed-source binary files.

Double-Edged Sword Risk: From Defense to Proliferation of Abuse

While this capability strengthens defense, it is also easily exploited by attackers. Experts warn that the vulnerability exploitation window has been compressed from months to minutes, and complex attacks will become “completely ubiquitous.”

Anthropic proactively notified the US government and restricted the model’s public release to prevent it from falling into malicious hands.

Financial Sector Emergency Response

• IMF Managing Director Kristalina Georgieva warns: The global monetary system is “not yet ready” to cope with AI-driven cyber risks, calling for regulatory firewalls

• US Treasury Secretary Scott Bessent and Fed Chair Jerome Powell convened CEOs from Citigroup, Goldman Sachs, and other banks to assess threats

• Bank of England, Financial Conduct Authority, and National Cyber Security Centre hold emergency consultations

These actions highlight that AI risks have become systemic financial threats.

Project Glasswing: Industry Collaborative Defense

Anthropic launched Project Glasswing, granting controlled access to over 40 companies including Microsoft, Amazon, Google, Apple, and Cisco:

The project emphasizes strict access controls to ensure “proactive defense.”

Paradigm Shift: International Cooperation Imperative

Cisco’s Chief Security Officer notes that AI has changed the urgency of protecting critical infrastructure; OpenAI also plans limited release of similar products.

Expert consensus: Borderless issues require global collaboration to prevent attack capability proliferation.
