Over 100 companies warn that AI-powered cyberattacks will surge in the coming months.

Breaking News from Beating AI: Over 100 companies, including OpenAI, Anthropic, Google, Microsoft, and AWS, have jointly issued an open letter urging immediate strengthening of cyber defenses. Companies such as Cloudflare, CrowdStrike, Cisco, Visa, and Oracle are also on the list. These companies warn that over the coming months, AI will make cyberattacks more frequent and harder to defend against, with critical systems like hospitals, water treatment plants, and internet infrastructure facing particularly high risks. Previously, attackers had to spend time manually discovering vulnerabilities and developing attack tools; now, much of this work can be automated by AI, lowering the barrier to launching attacks. The open letter also offers several specific recommendations: businesses should urgently patch critical vulnerabilities, cybersecurity firms should share threat intelligence more widely, and governments should provide increased funding and technical support to essential services like healthcare and water utilities. AI companies such as OpenAI and Anthropic should make their models, tools, and training resources available to defenders, enabling security teams to use AI to detect and remediate vulnerabilities.
