SonicWall''s intrusion prevention sensors across UK healthcare clients logged **264,000 attack events between January and May 2026**, compared with just **27,000 for the whole of 2025** — a roughly tenfold rise in five months, and more events per sensor than any other vertical the vendor tracks. The findings, first reported by Infosecurity Magazine (https://www.infosecurity-magazine.com/news/uk-healthcare-tenfold-increase/), point to a sector caught between two pressures: legacy clinical systems that cannot be patched on a normal cycle, and new patient-facing web services that are being pushed live faster than they can be hardened. ## What the attackers are targeting SonicWall''s telemetry shows a mix of old flaws and fresh vulnerabilities under active exploitation across UK trusts and their suppliers: - **Log4Shell (41% of events).** The 2021 Java logging vulnerability is still the single most active attack vector against UK healthcare in 2026 — a direct signal that Java middleware embedded in NHS workflows has not been updated. - **React2Shell.** A critical remote code execution flaw in the React.js library, showing up in newly deployed patient portals that were built on top of vulnerable dependencies. - **F5 BIG-IP authentication bypass (33% of sensors).** Load balancers widely used across the health service being probed for auth bypass. SonicWall''s EMEA executive vice president Spencer Starkey framed it as a "double-edged crisis": > "Attackers are targeting our hospitals, and stress-testing them to breaking point. Zombie tech, ancient unpatched systems and legacy Java keep haunting the NHS because administrators can''t just take a critical care system offline to patch it. Meanwhile, the rush to digitise has opened the door to brand-new web vulnerabilities in patient portals. Threat actors have clocked the gap between old and new, and they''re scanning for it relentlessly." The surge coincides with a wider global rise in ICS and operational technology attacks from early 2026, with intensified targeting attributed in part to Iranian activity. ## Why this matters beyond the NHS Healthcare is a canary. The same pattern — critical services that can''t be taken offline, tightly coupled to Java-era middleware, wrapped in modern web front-ends — sits behind local government, utilities, legal services and financial back offices across the UK. The NCSC has already published a plan (https://www.infosecurity-magazine.com/news/ncsc-plan-boost-nhs-cyber/) to lift cyber resilience across the NHS, but plans do not patch middleware and they do not shrink an attack surface that is already exposed. For boards and CISOs the practical question is not whether Log4Shell will be patched this quarter. It is: **when a clinical system, patient portal or load balancer is compromised, what still works?** ## Firevault''s view Firevault sits inside the ecosystem the SonicWall data is describing. Our position is that critical records — patient data, evidential records, incident logs, backups and recovery keys — should not sit on the same estate as the internet-facing systems being scanned relentlessly. - **Offline Secure Storage (https://fire-vault.com/offline-secure-storage) (OSS).** Gold-copy records held off-network in air-gapped vaults, so that a compromised portal, middleware or load balancer cannot reach or encrypt the data that matters most. - **Control.** Retrieval only after identity verification, on scheduled access windows, with every session logged for regulatory and clinical audit trails. - **Resilience by design.** Recovery does not depend on the same infrastructure that is under attack. If the estate is degraded, the record of truth is still intact and reachable through a separate control path. None of this replaces patching, network segmentation or NCSC-aligned resilience work. It reduces the blast radius when those defences are outpaced — which, on SonicWall''s numbers, they clearly are. ## What to do this quarter 1. **Inventory Java middleware and shared libraries** used by clinical, patient-portal and supplier systems. Assume Log4Shell exposure until proven otherwise. 2. **Separate gold-copy records from production.** Move authoritative copies of patient, clinical and evidential data to offline, air-gapped storage with controlled retrieval. 3. **Test recovery without the production estate.** If the primary environment is compromised, can you reconstitute service from records that never touched the internet-facing network? 4. **Map controls to CAF outcomes** rather than chasing certifications alone. The CAF framework gives NHS and public-sector suppliers a clear objective-led target for resilience. The tenfold rise is not a forecast. It is a measurement. The gap between old systems and new web surfaces is where UK healthcare is being hit right now — and it is the same gap that OSS and Control are designed to close. _Source: UK Healthcare Sector Records Tenfold Increase in Cyber-Attacks — Infosecurity Magazine, 30 June 2026 (https://www.infosecurity-magazine.com/news/uk-healthcare-tenfold-increase/)._ About the author ### Mark Fermor Mark Fermor on LinkedIn (https://www.linkedin.com/in/mfermor) CTO, CMO & Founder Founder of Firevault, focused on offline secure storage and protecting individuals and businesses from fraud, fines, loss and damage.
