Leaders at OpenAI, Anthropic, Google and Microsoft warned that organizations have only a “limited window”—potentially just months—to harden systems before AI-powered attacks scale. An open letter signed by security firms and banks urged companies to replace vulnerable legacy technology, tighten authentication, and invest in AI-enabled defense tools, citing CrowdStrike data showing an 89% rise in AI-driven attacks in 2025 from 2024. Signatories pressed for wider threat-intelligence sharing and measurable outcomes like faster containment times. They also called on governments to coordinate funding and policy responses, and on AI developers to provide responsible access to models and bolster their own security.
