> NCSC's State of the Cyber Nation report predicts AI will enable faster exploitation of known weaknesses, risking a ransomware attack on UK critical infrastructure by 2028.

## What to check

- Applies to: Not tied to a specific actor, malware or CVE, only to the sectors it covers, so it may be general reporting. Check the source before acting on it. Whether it concerns you is not assessed.

The UK's National Cyber Security Centre (NCSC), part of GCHQ, published its 'State of the Cyber Nation' report warning that AI adoption by hostile actors is 'highly likely' to increase the scale and efficiency of attacks including ransomware, social engineering, and vulnerability exploitation within the next two years. NCSC CEO Dr Richard Horne argues the risk stems not from AI inventing new attack methods, but from AI's ability to discover and exploit longstanding, under-invested security weaknesses at unprecedented speed and scale—attributing this exposure to decades of organisations pursuing 'tech on the cheap.'

The report calls on UK organisations to urgently invest in foundational security: addressing technology under-investment, removing unnecessary internet-facing connectivity, and treating Cyber Essentials as a baseline rather than an end goal. It coincides with UK government funding announcements including £60 million for a national 'Cyber Shield', £70 million for a new National Exposure and Real-Time Vulnerability (NERV) Centre, and an AI Cyber Security Centre of Excellence in Manchester.

No specific threat actor, malware, campaign, vulnerability, or indicator of compromise is identified in this report—it is a strategic/policy warning rather than incident-specific intelligence. Defenders should treat this as a call to prioritise basic cyber hygiene (patching, reducing internet exposure, resilience planning) ahead of anticipated AI-accelerated exploitation trends, particularly within critical national infrastructure sectors.
