OpenAI and over 100 companies warn that AI-powered cyberattacks on critical infrastructure are imminent.
They urge businesses, governments, and AI firms to act now.
A recent US warning confirms attackers already use AI.
What happened
OpenAI published an open letter on global cyber defense, co-signed by more than 100 companies including Microsoft, Google, AWS, Anthropic, Cisco, CrowdStrike, Deutsche Telekom, SAP, and Mastercard.
Why it matters
The letter warns that AI-enabled cyber attacks will become far more widespread and sophisticated, with hospitals, water utilities, and other critical infrastructure at highest risk. It urges deploying AI tools while defenders still have an edge.
What to watch
A joint NSA, CISA, and FBI warning from mid-August reveals attackers are already using AI to write exploit scripts targeting industrial control systems like Siemens S7 across US energy, water, chemicals, and manufacturing sectors.

The open letter marks a coordinated push by major tech and cybersecurity firms to highlight the growing threat of AI-powered cyberattacks. The signatories argue that while AI gives defenders new ways to fix long-standing weaknesses, attackers are also gaining capabilities. The mid-August warning from US agencies provides concrete evidence that AI is already being used maliciously, targeting industrial control systems. This context suggests the letter is a call to action, urging stakeholders to invest in defenses before the threat escalates further.
