Richard Horne, the head of the UK’s National Cyber Security Centre (NCSC), warned that the threats to the UK are wildly underestimated by both individuals and organisations. He stated that a sharp rise in severe cyber incidents, including attacks on healthcare, transportation, and other critical sectors, has become more frequent, sophisticated, and intense, as highlighted by intelligence from GCHQ (Government Communication Headquarters). Horne described how hostile states like Russia and China, along with organised criminals, are exploiting weaknesses. He said, “Complacency is not an option,” calling for immediate action to close the widening gap between the growing threats and the measures to counter them by accelerating efforts to stay ahead of adversaries.
The nation’s new cyber security chief’s vision is focused on resilience and preparation. He emphasised the importance of making cyber security a part of everyday routines, both professionally and personally. The rapid evolution of risks requires collective action, with tools like the NCSC’s Cyber Essentials playing a key role in improving security. He stressed the need for everyone, businesses and individuals, to take proactive steps to enhance security, remain alert to new risks and adapt to defend from constantly evolving attackers using advanced technology, such as artificial intelligence and sophisticated malware

NCSC Annual Review 2024
The NCSC Annual Review 2024 reflects the concerns raised by Richard Horne. It highlights the growing threats to the UK and the urgent need to improve cyber defences. Some of the key points from the report are as follows:
- Increasing Cyber Incidents: The NCSC managed 430 significant cyber incidents this year, up from 371 last year. This includes 89 incidents deemed nationally significant and 12 of the highest severity, highlighting the increasing frequency and impact of attacks.
- Key Sectors Under Attack: Several key sectors, including healthcare and transportation, faced significant challenges from cyberattacks. These incidents disrupted essential services and required coordinated responses, such as deploying cyber defence teams, patching vulnerabilities, and restoring affected systems. While many issues were mitigated, the incidents revealed ongoing vulnerabilities that need further attention.
- Ransomware Dominance: Ransomware continues to be one of the most prevalent and damaging threats, causing financial losses and service disruptions across both public and private sectors. Examples include the British Library cyber-attack on 28 October 2024, which disrupted services and required extensive recovery efforts; and the Synnovis ransomware attack on 21 Jun 2024, which impacted healthcare operations across six NHS trusts which caused significant operational disruptions and exposed critical vulnerabilities.
- State-Sponsored Threats: Hostile states, including Russia and China, remain persistent adversaries. Examples from the NCSC Annual Review 2024 include cyber-attacks on the UK’s energy sector in March 2024, which sought to disrupt power supplies, and an attack on a major financial institution in September 2024 that targeted sensitive data. These incidents highlight the sophisticated techniques used to undermine critical infrastructure and the economy.
- Emerging Technologies: Attackers are increasingly using artificial intelligence (AI) to automate and enhance their attacks. The NCSC Annual Review 2024 highlights AI’s role in creating convincing phishing attempts, finding system vulnerabilities, and bypassing traditional defences. Additionally, the report flags quantum computing as a future risk, with potential to break encryption standards. These developments stress the need for adaptive security measures and AI-powered defences.
- NCSC Initiatives: The report highlights key programs like Cyber Essentials, which provides simple steps for organisations to protect against common threats like phishing and ransomware. The Cyber Advisor Scheme offers expert support to small and medium-sized businesses, while Active Cyber Defence tools reduce the impact of attacks across the public sector. Exercise in a Box helps organisations test and improve their response to cyber incidents. These initiatives aim to enhance resilience and equip businesses of all sizes with effective defences.
- Collaboration Is Key: The NCSC emphasises the importance of collaboration between the public and private sectors to build a unified defence against cyber threats. This includes leveraging the expertise of cyber security consultants who provide tailored advice and solutions to enhance organisational resilience. By working with experts and sharing knowledge across industries, the UK can strengthen its defences and better respond to emerging challenges.
How We Should Act
For individuals and businesses in the UK, the NCSC’s findings highlight the urgent need for action. Individuals can reduce risks by using strong passwords, enabling multi-factor authentication, staying alert to scams, keeping software updated, and backing up important data. For businesses, embedding cyber security in operations is crucial. This includes adopting frameworks like Cyber Essentials, training employees to recognise threats, and preparing response plans. The risk is real and the concern is genuine, so collaboration between individuals, organisations, and the NCSC is essential to building stronger defences and staying ahead of evolving cyber threats.
