# OpenAI, Anthropic, Google, and 100+ companies warn of AI cyberattacks

> More than a hundred technology companies, including rivals that rarely agree on anything, have signed a joint open letter warning that AI-enabled cyberattacks are about to get a lot more common and a lot harder to stop. The signatories span the frontier labs like OpenAI, Anthropic and Google alongside security heavyweights such as CrowdStrike, Microsoft and Okta, and their shared message is blunt: the same models that write code and automate workflows can also probe networks, craft convincing phishing, and chain together attacks faster than human defenders can respond. Critical infrastructure, they argue, is the softest and scariest target. The letter calls for tighter public-private collaboration, shared security standards, and coordinated countermeasures rather than every company fending for itself. There is an obvious tension worth naming: several of the same firms sounding the alarm are also busy selling AI defensive products, so the warning doubles as a market pitch. That does not make the risk fake. It does mean readers should watch what these companies build next, not just what they sign, and ask whether voluntary standards can keep pace with tools that are already in wide release.
