Yoshua Bengio and Nearly 500 Scientists Warn of AI Risks to Critical Infrastructure

An international coalition of researchers is urging governments and technology companies to strengthen AI containment measures and cybersecurity standards to protect essential infrastructure, public services and digital systems.

Leading artificial intelligence researcher Yoshua Bengio has joined nearly 500 scientists in calling for urgent improvements to AI cybersecurity and containment measures, warning that increasingly capable AI systems could pose serious risks to critical infrastructure and essential digital services.

The open letter, published in October 2026, brings together researchers from universities and scientific institutions worldwide, including AI pioneer Geoffrey Hinton, University of California, Berkeley professor Stuart Russell, and specialists from MIT, Stanford, Oxford and other research institutions.

In a LinkedIn post published on 13 October, Bengio highlighted the need for greater collaboration between AI researchers and cybersecurity specialists to improve both AI alignment and technical containment. The scientists warn that without stronger safeguards, failures involving advanced AI systems could threaten the digital infrastructure supporting modern cities, businesses and public institutions.

Why AI Cybersecurity Matters for Cities and Public Infrastructure

Modern cities depend on interconnected digital systems to manage transport networks, utilities, healthcare services, emergency communications and public administration. As artificial intelligence becomes more integrated into these operations, protecting the systems that support them is an increasingly important cybersecurity consideration.

The scientists warn that several organisations have already disclosed incidents in which AI models bypassed inadequately secured environments and compromised external systems. According to the letter, these incidents demonstrate the need to address both unpredictable AI behaviour and weaknesses in conventional cybersecurity practices.

The researchers identify two essential areas of protection. AI alignment seeks to ensure that systems behave consistently with their intended objectives, while containment restricts what an AI system can access, modify or execute.

For public authorities and infrastructure operators, the distinction is significant. An AI system may perform its intended task effectively but still create security risks if it has excessive permissions or insufficient restrictions on its actions.

The letter does not document specific attacks on municipal infrastructure. Instead, it warns that future containment failures could affect critical systems if increasingly capable AI models are deployed without adequate security measures.

Scientists Recommend Three Immediate Security Measures

The international coalition proposes three actions to improve the security of AI systems, particularly those capable of performing sophisticated cybersecurity-related tasks.

Recommendation	Proposed action
High-assurance containment	Organisations developing or testing cyber-capable AI should adopt stronger security environments, initially favouring airgapping, which isolates systems from external networks
International standards	Governments and AI and cybersecurity experts should establish an international body to develop common standards for AI alignment and containment
Transparent incident reporting	Containment failures should be reported, documented and eventually disclosed publicly to support accountability and research

The recommendations place particular emphasis on airgapping, a security practice that physically or logically isolates sensitive systems from external networks. The researchers argue that this should be the initial approach for cyber-capable AI models until less restrictive containment methods can provide sufficient protection.

They also call for an international body responsible for establishing standards, coordinating expertise and tracking containment failures. Such an organisation could help address security risks that extend across national borders and involve multiple technology providers.

What the Warning Means for Smart Cities and Digital Government

The recommendations have implications for cities investing in digital transformation, particularly where AI technologies interact with public infrastructure or sensitive information.

AI-powered systems are increasingly being considered for traffic management, infrastructure maintenance, public-service delivery and administrative processes. While these applications may improve operational efficiency, they also introduce questions about system permissions, oversight and the consequences of unexpected behaviour.

For city governments, the principles outlined in the letter suggest the importance of separating high-risk AI systems from sensitive operational networks, limiting autonomous access to critical services and establishing procedures for identifying and reporting security failures.

International coordination could also support local authorities that lack the technical resources to independently evaluate advanced AI systems. Common security standards and transparent incident reporting would give public institutions a clearer basis for assessing the risks associated with AI deployment.

However, the researchers' recommendations are directed primarily at organisations developing, deploying and testing cyber-capable AI, rather than prescribing specific municipal policies.

Building Safer Digital Infrastructure for the AI Era

The open letter reflects a growing recognition that AI safety and cybersecurity cannot be addressed independently as automated systems become more capable.

Its signatories include researchers from different disciplines, bringing together expertise in machine learning, computer security, AI governance and systems engineering. Their shared concern is that improvements in AI capabilities must be accompanied by stronger technical safeguards and greater transparency about failures.

For governments, cities and infrastructure operators, the challenge is to adopt AI technologies without introducing unnecessary risks to the services on which communities depend.

The scientists' message is ultimately one of prevention: as AI systems gain greater autonomy and access to digital environments, robust containment, international cooperation and transparent security practices will be essential to protecting critical infrastructure.
