OpenAI, Anthropic, Microsoft, AMD and over 100 other companies and organizations signed a joint letter urging businesses and governments to urgently strengthen cybersecurity defenses as AI-driven threats accelerate. The signatories called for stronger security tools, wider adoption of both low-cost and frontier AI models, and government funding to help under-resourced sectors like hospitals and water utilities defend themselves.

The letter reflects growing alarm that AI can now automate complex cyberattacks in minutes, outpacing traditional defenses built for slower, human-driven threats. By uniting rivals across cybersecurity, cloud, semiconductor and finance industries, the initiative signals that AI-enabled attacks are seen as an industry-wide emergency rather than a niche technical issue, and that critical infrastructure gaps could have national security consequences if left unaddressed.
