The cyber risks brought about by frontier AI include more affordable and faster attacks, as well as a wider range of impacts. The Bank of England calls for more stringent testing of the AI model and promotes global security cooperation.

Andrew Bailey, Governor of the Bank of England, has warned that the cutting-edge AI brings not only faster attacks: this technology may also make attacks cheaper, expand their impact range, and put sophisticated capabilities into the hands of more people. He calls for more stringent testing before and after the deployment of the AI model, and for society to be given the right to intervene in deployment decisions.

Key Points

• Pelé stated that cutting-edge AI can lower the threshold for carrying out complex cyberattacks.
• The Bank of England mentioned an assessment of OpenAI GPT -5.5 in April 2026.
• His suggestions include ongoing model testing as well as international security cooperation.

Frontiers AI How to Increase Network Risks

Beali stated that cutting-edge AI can accelerate cyberattacks, increase the number of targets that can be reached, and reduce costs. A joint statement issued by the Bank of England, the Financial Conduct Authority, and the UK Treasury emphasized another change: the model can perform tasks that previously required skilled human operators.

This capability expands the group of potential attackers. Tasks that were previously limited to a small number of technically skilled individuals can now be increasingly accomplished by software.

Pele also serves as the chairman of the Financial Stability Board. In a letter to Finance Minister G20, he stated that frontier AI "could substantially change the speed, scale, and economics of network risks."

Evidence Behind the Warnings

As a basis for its concerns, the Bank of England mentioned an assessment of the network capabilities of OpenAI GPT -5.5 conducted in April 2026. The research results described in the warning indicate that as of May 15, 2026, the advanced models demonstrated network attack capabilities that surpassed those of skilled human professionals.

Therefore, concerns are not only related to the performance of the model itself but also to the ability to achieve such performance. Bailey's warning links stronger technical capabilities with the possibility of launching attacks faster and more cheaply.

Tests are required before and after deployment.

The countermeasures proposed by Pelé regarding the cutting-edge AI network risks include conducting rigorous testing both before and after deployment, rather than considering the deployment as the end of the assessment process. He also called on countries to cooperate on the AI security protocols.

His suggestions also include establishing a social right to intervene in these technological deployment issues. In a commentary article, he advocates for the establishment of a regulatory framework that can keep up with the development speed of AI, and states that these risks are real and increasingly important.

The Bank of England is also collaborating with AI Security Research Institute and the National Cybersecurity Center. Related work includes addressing an increasing number of vulnerabilities that require faster patching.

Financial stability concerns are not limited to individual institutions.

For financial institutions, the resilience priorities proposed by the Bank of England include detection, containment, and recovery, as well as being prepared for the increasing number of vulnerabilities related to the progress of AI.
