On August 27, 2026, OpenAI published an open letter alongside 128 companies and organizations, including Anthropic, AWS, Google, Microsoft, and Oracle, calling for the strengthening of cyber defense through AI. The letter warned that AI-powered cyberattacks are expected to become significantly more widespread and sophisticated within the coming months, posing a risk to critical social infrastructure such as hospitals, water purification facilities, and the internet backbone.
The letter outlines three principles: acknowledging that current security measures are insufficient, delivering AI tools for cyber defense to a broader range of defenders, and advancing collective responses. It requests specific actions from four key stakeholders: organizations, security firms and technology partners, governments, and frontier AI companies.
Sam Altman, of OpenAI, also posted on X on the same day, stating, "There is little time left to act." He expressed welcome for collaboration not only with OpenAI but also with competitors and partners, urging that only urgent and thorough collective action would be effective.
