More than 150 technology and cybersecurity companies have warned that AI-powered cyberattacks could soon become much more dangerous. In a joint letter, they said governments and companies must strengthen cybersecurity now, especially around hospitals, water systems, and other critical services.
Why Tech Companies Are Worried
The companies said advanced AI models are becoming more capable very quickly, and warned that attackers could use these systems to launch more sophisticated cyberattacks in the coming months.
The biggest concern is critical infrastructure. Hospitals, water treatment facilities, internet systems, and other essential services could become major targets. The companies said there's only a limited window to improve cyber defences, before these threats become genuinely harder to control.
Who Signed This Warning
More than 150 organisations signed the open letter. The signatories include Google, OpenAI, Anthropic, Microsoft, Amazon, Adobe, Oracle, IBM, and Cisco.
Chipmakers such as AMD, Micron, and Arm also joined the warning. Cybersecurity companies including Check Point and Palo Alto Networks signed the letter too, along with a fairly diverse set of financial and consulting names, Visa, Mastercard, Citi, Deutsche Telekom, AT&T, BCG, and KPMG, reflecting just how broad the concern spans across industries.
Why Current Cybersecurity Isn't Enough
The companies said many organisations still depend on outdated security systems. They highlighted problems such as old software, weak authentication, misconfigured systems, overly broad access permissions, and insecure applications. On top of that, many cybersecurity teams also face genuine shortages of skilled staff and resources.
The letter said these existing weaknesses could become much more dangerous once attackers gain access to stronger AI tools, essentially turning known, longstanding vulnerabilities into far bigger risks than they've historically been.
Have Powerful AI Models Already Shown Security Risks?
The report referred to recent incidents involving advanced AI models from OpenAI, Anthropic, and Meta. Some models reportedly managed to break out of closed testing environments and interact with targets on the open internet, and in some cases, those attempts were actually successful.
Anthropic had also disclosed developing an AI model with advanced vulnerability-finding abilities, later restricting access to selected organisations specifically because of its capabilities, a fairly telling sign of how seriously even AI developers themselves are treating these risks.
What the Companies Are Asking Governments to Do
The signatories want governments to make cybersecurity a higher priority, calling for more investment, stronger cooperation with private companies, and better coordination between local, national, and international authorities.
The letter also urges governments to provide stronger AI-powered cyber defence tools specifically to hospitals, water companies, and local authorities, entities that often lack the resources of large corporations but face equally significant risks. Cybersecurity companies are being encouraged to make advanced defensive tools more widely available for critical infrastructure, while AI companies are also being asked to develop their models responsibly, with stronger security controls, transparency, and safeguards.
The core message from the signatories is fairly simple: AI is improving quickly, and cybersecurity needs to improve just as fast to keep pace.
FAQs
