The National Cyber Security Centre publishes an annual threat assessment. The 2024 edition was the most alarming in the organisation's history. Nation-state actors — primarily from Russia, China, North Korea, and Iran — mounted a record number of attacks on UK government systems, critical national infrastructure, and private sector targets.
Most of these attacks were detected and repelled. Some were not.
The Threat Landscape
The most significant escalation has been in attacks on operational technology — the industrial control systems that manage power grids, water treatment facilities, transport networks, and hospitals.
Unlike data breaches, which primarily cause financial and reputational damage, attacks on operational technology can have physical consequences. The disruption to hospital IT systems in 2024, attributed to a ransomware group with suspected state links, delayed thousands of appointments and may have contributed to patient harm.
The Structural Weakness
Britain's critical infrastructure is overwhelmingly operated by private companies — the utility sector, the telecommunications networks, the financial system. Securing it requires cooperation between government and industry that has historically been incomplete.
The regulatory framework for cybersecurity is fragmented. Different sectors face different requirements, with varying levels of rigour and enforcement.
What Needs to Happen
A coherent national cybersecurity strategy — backed by mandatory standards, real enforcement, and genuine information sharing between public and private sectors — is no longer optional.
