On Thursday, Sam Altman declared that the world had reached a “critically important moment for cyber defense with AI” and that there was “not much time to act”. The same day, OpenAI, Anthropic, Microsoft, Google, and Amazon joined more than 100 other organizations in an open letter saying that “in the coming months, AI-enabled cyber attacks will become far more widespread and sophisticated.” Signatories to the letter included major security vendors, banks, and infrastructure operators.

The letter argues that hospitals, water treatment plants, and internet infrastructure are exposed to cybersecurity risk, but that AI now gives defenders a window to fix weaknesses that accumulated over years. It also calls on the government to expedite trusted access programs, which grant selected companies early access to more capable models before general release. It also asks governments to fund cyber defense for under-resourced essential services. Doing so would require a change of course, as the Cybersecurity and Infrastructure Security Agency (CISA) cut a third of its staff last year after budget cuts.
