**T**he UK's critical national infrastructure could face a ransomware attack involving AI-powered malware by 2028, according to a warning from the National Cyber Security Centre (NCSC).

In its latest *State of the Cyber Nation* report, published on 3 November 2026, the NCSC says it is highly likely that hostile actors will increase their use of artificial intelligence over the next two years. The technology could make their operations more efficient and increase the scale of activities such as ransomware attacks, social engineering and vulnerability exploitation.

The report, published by the NCSC, which is part of the UK's signals intelligence agency GCHQ, also warns that longstanding weaknesses in organisational cybersecurity could become easier for attackers to identify and exploit.

Its message to organisations is direct: years of underinvestment in technology and security have left weaknesses that AI could help adversaries exploit more quickly and at greater scale.

## 
AI Could Increase the Scale of Existing Cyber Threats

The NCSC's warning does not suggest that artificial intelligence has created entirely new methods of cyberattacks. Instead, it highlights how AI could make existing attack techniques more effective.

Hostile actors are expected to make greater use of AI in three areas:

- **Ransomware:** AI-powered malware is considered highly likely to be used in a ransomware attack against UK critical national infrastructure by 2028.
- **Social engineering:** AI adoption could increase the scale and efficiency of efforts to manipulate people into giving attackers access or information.
- **Vulnerability exploitation:** AI could help hostile actors identify and exploit existing weaknesses more efficiently.

This distinction is important. The report argues that the underlying problem is not only the development of new attack technologies. It is also the presence of security gaps that organisations have tolerated for years.

## 
Why Existing Security Weaknesses Matter

In his speech launching the report, NCSC Chief Executive Dr Richard Horne is expected to warn that AI will expose vulnerabilities, technology failures and underinvestment at unprecedented speed and scale.

He argues that organisations have reached a point where treating security as an optional investment is no longer sustainable.

The NCSC's concern is that attackers could use AI to find weaknesses that have remained unnoticed or unresolved. As a result, organisations with poor security foundations may face greater exposure even when the attack techniques themselves are not entirely new.

## NCSC Calls an End to "Tech on the Cheap"

A central theme of the report is the need for organisations to stop treating cybersecurity as an afterthought.

Dr Richard Horne is expected to describe the UK's approach to technology investment as an era of "tech on the cheap", where organisations have prioritised cost savings at the expense of security and resilience.

The NCSC is urging leaders to make different decisions before attackers take advantage of these weaknesses.

In his launch speech, Horne is expected to say:

**"In the coming months, we face a real prospect of an unprecedented rise in the number of cyber incidents. But we must be clear that is not because AI has invented new ways to attack us. But because vulnerabilities that have been tolerated for far too long can now be discovered and exploited at a once unimaginable scale."He will also call for organisations to make security and resilience fundamental requirements rather than considerations added after technology decisions have been made.The report describes this as a "moment of choice" for organisations across the country.

## 
Three Areas Where Organisations Need to Act

The NCSC identifies several decisions that organisations should address:
1. Invest adequately in technology**

Organisations need to address years of insufficient investment in their technology and security foundations. Security should be considered when making technology decisions, rather than treated as an additional expense.

**2. Reduce unnecessary internet exposure**

Technology and services should not be connected to the internet without a clear operational need. Reducing unnecessary exposure can help limit opportunities for attackers to identify and target vulnerable systems.

**3. Treat Cyber Essentials as a starting point**

The NCSC says Cyber Essentials should be the beginning of an organisation's cybersecurity efforts, not the final objective. Organisations should build additional resilience according to their size, complexity and risk.

The report's position is that a single baseline is not enough for every organisation. Security measures need to reflect the systems an organisation operates and the consequences of a successful attack.

## 
Government Announces New Investment in UK Cyber Defence

The warning comes as the UK government increases investment in cyber defence and resilience capabilities.

Alongside the report, the government is taking action through the Cyber Security and Resilience Bill and the forthcoming National Cyber Action Plan. These initiatives are intended to strengthen the UK's defences, deter hostile state activity and help keep essential services running.

The Chancellor also announced additional investment in capabilities intended to help the UK use AI for cyber defence.

The announced measures include:

- **£60 million for the first phase of a national Cyber Shield.**
- **£70 million for a National Exposure and Real-Time Vulnerability (NERV) Centre**, intended to identify vulnerabilities across critical infrastructure and the wider economy.
- **An AI Cyber Security Centre of Excellence in Manchester**, run by the NCSC, to develop AI security expertise within government.

These investments form part of the wider effort to strengthen national cyber resilience. The announcement does not provide further operational details about the Cyber Shield or the NERV Centre in the supplied material.

## Critical Infrastructure and Essential Services Face Wider Risks

The NCSC's warning extends beyond individual organisations. It highlights the potential consequences for the UK's economy and society if cyber weaknesses remain unaddressed.

Critical national infrastructure supports essential services and economic activity. A successful ransomware incident involving these systems could therefore have consequences beyond the organisation directly affected.

Dr Horne is expected to warn that leaders who fail to invest in resilience may eventually have to explain the consequences to investors, employees, customers and suppliers, including situations where food is unavailable on shelves, electricity is disrupted or businesses fail.

The report does not describe a specific future victim or attack scenario. Its warning is about the likelihood of AI being used in ransomware activity against critical national infrastructure by 2028 and the need to prepare before such an incident occurs.

## 
The Role of Existing Cybersecurity Standards

The NCSC is urging organisations to make use of existing tools, standards and frameworks that are already available and have demonstrated value in protecting against conventional and AI-powered attacks.

Cyber Essentials is highlighted as a starting point. However, organisations are expected to go further based on their individual risk profiles.

This places responsibility on organisational leaders as well as technical security teams. Investment decisions, internet exposure, technology management and resilience planning all influence how prepared an organisation is to withstand cyber threats.

## AI Presents Both a Cybersecurity Risk and an Opportunity

Although the report warns about hostile actors using AI, it also recognises the technology's potential to improve the UK's cyber defences.

The NCSC sees AI as an important opportunity to strengthen collective resilience. However, organisations need to address foundational weaknesses if they are to benefit from the technology without leaving themselves exposed.

This creates a dual challenge: defenders need to use AI to improve cybersecurity while preparing for adversaries to use the same technology to increase the efficiency and scale of their operations.

The government-backed Cyber Shield, NERV Centre and AI Cyber Security Centre of Excellence are part of the wider effort to develop national capabilities. The report also calls on organisations to use existing security standards and frameworks rather than waiting for new technologies to solve longstanding problems.

## 
What the Warning Means for UK Organisations

The NCSC's 2026 report places responsibility on organisations to act before AI-enabled threats become more widespread.

Its message is not that every organisation will experience an AI-powered attack by 2028. Rather, it assesses that AI-powered malware is highly likely to be used in a ransomware attack against the UK's critical national infrastructure within that timeframe.

For businesses and operators of essential services, the practical challenge is to identify weaknesses that already exist, reduce unnecessary exposure and make security a core part of technology investment.

The report also highlights that cybersecurity cannot be treated as a one-time compliance exercise. Cyber Essentials provides a baseline, but resilience needs to develop according to an organisation's size, complexity and risk.

## 
A Critical Choice for the UK's Cyber Resilience

The NCSC's warning highlights a growing challenge for the UK's cybersecurity landscape. AI could make existing attack techniques more efficient, but the impact will also depend on how well organisations have secured their systems.

The report calls for a shift away from short-term technology savings and towards sustained investment in security and resilience.

With the NCSC assessing that AI-powered malware is highly likely to feature in a ransomware attack against UK critical national infrastructure by 2028, the message to organisational leaders is clear: longstanding weaknesses need attention now, before adversaries exploit them at greater scale.
