State of Ransomware in the UK: 2026 Report

The UK Ransomware Landscape in Numbers

The NCSC's Annual Review 2024 reported managing 317 significant cyber incidents, up from 258 the previous year. Of these, 150 involved ransomware or data extortion. The UK Government's Cyber Security Breaches Survey 2024 found that 50% of businesses and 32% of charities reported cyber breaches or attacks in the previous 12 months. Sophos's State of Ransomware 2024 report found that 59% of UK organisations experienced a ransomware attack, with 44% having their data encrypted. The average ransom payment for UK organisations reached $2.1 million, while the average total recovery cost including downtime hit $3.58 million.

Most Targeted UK Sectors

Healthcare, education, and local government remain the most targeted sectors in the UK. The NHS has been hit repeatedly — the Synnovis pathology lab attack in June 2024 disrupted services at King's College Hospital, Guy's and St Thomas', and over 200 GP practices across South East London, forcing cancellation of more than 800 operations. Education faces persistent targeting because of limited budgets and high-value data: 14 UK universities disclosed ransomware incidents in 2024 alone. Local councils including Hackney, Redcar & Cleveland, and Gloucester have all suffered extended outages from ransomware in recent years.

• Healthcare: NHS Synnovis attack disrupted 200+ GP practices
• Education: 14 UK universities hit in 2024
• Local government: Hackney recovery took 2+ years
• Legal sector: 77% of law firms report attempted breaches (SRA)
• Financial services: FCA reported 31% increase in cyber incidents

The Evolution of Ransomware Groups

LockBit was the most prolific ransomware group globally until the NCA's Operation Cronos disrupted their infrastructure in February 2024. Despite this, LockBit attempts to rebuild, and other groups have filled the void. ALPHV/BlackCat executed a notable exit scam in March 2024, pocketing a $22 million ransom from Change Healthcare. Cl0p shifted entirely to data theft without encryption, as seen in the MOVEit campaign. New groups including RansomHub, Hunters International, and Akira have rapidly scaled operations. The NCSC assesses that ransomware will remain the most significant cyber threat to UK organisations through 2027.

NCSC Guidance and What to Do Now

The NCSC recommends a defence-in-depth approach: keep systems patched, enforce MFA, maintain offline backups, and implement network segmentation. But their 2024 guidance also explicitly added "monitoring outbound data flows" as a recommended control — recognition that data exfiltration is now the primary damage vector. At Kyanite Blue, we layer Coro for endpoint detection, Hadrian for attack surface monitoring, and BlackFog for anti data exfiltration. This combination addresses the full ransomware lifecycle: reconnaissance, initial access, lateral movement, and exfiltration.

• Patch critical vulnerabilities within 14 days (NCSC recommendation)
• Enforce phishing-resistant MFA across all accounts
• Maintain offline, tested backups with documented recovery procedures
• Deploy ADX to block data exfiltration — the real damage vector
• Report ransomware incidents to Action Fraud and the NCSC

Should You Pay the Ransom?

The NCSC, NCA, and UK Government advise against paying ransoms. Payment funds criminal operations, does not guarantee data recovery, and marks you as a willing target for future attacks. The Ransomware Task Force found that 80% of organisations that paid were attacked again. However, the UK has not yet criminalised ransom payments as some have proposed. The best strategy is prevention: if data never leaves your network, the extortion leverage disappears entirely.
