Breach #206

City payment systems down. Hospital clinics closed. Ransomware keeps targeting what people need most.

In February 2026, BridgePay — a payments platform whose customers include numerous city governments — was hit by ransomware that disrupted payment processing services. City governments using BridgePay for utility payments, licence fees, and other municipal transactions reported outages. BridgePay stated that no credit card numbers were exposed, and the company fully restored its infrastructure by 28 February — but the disruption affected citizens' ability to make essential payments to their local authorities throughout the month.

In the same month, the University of Mississippi Medical Center (UMMC) was forced to close clinics after a ransomware attack disabled IT systems including electronic health records (EHR). Clinicians reverted to manual downtime procedures for patient care — paper records, verbal handoffs, and manual medication tracking. UMMC reopened clinics on 2 March. The incident was the latest in the relentless pattern of healthcare ransomware documented from Hollywood Presbyterian (2016) through WannaCry (2017), Düsseldorf (2020), the Irish HSE (2021), and Synnovis/NHS London (2024). Healthcare remains the most consistently targeted sector in this series.

Payments and patient care. The services people cannot do without.

Government Payment Systems
BridgePay's disruption affected citizens' ability to pay their local government — utilities, licences, taxes. For UK <a href="/blog/sector-under-the-microscope-local-government">local councils</a> using payment platforms, the BridgePay case demonstrates vendor dependency risk in citizen-facing services. <a href="https://www.socinabox.co.uk/sectors/local-councils">SOC in a Box for Local Government</a> monitors payment infrastructure.
Clinics Closed — Again
UMMC's clinic closures echoed every healthcare ransomware incident in this series. The pattern is now indisputable: healthcare ransomware closes clinics, delays treatment, and endangers patients. <a href="https://www.socinabox.co.uk/sectors/gp-surgeries">SOC in a Box for Healthcare</a> provides the 24/7 monitoring that detects ransomware before encryption completes.
Manual Downtime Procedures
UMMC's clinicians reverted to paper-based processes — demonstrating that tested downtime procedures are essential for maintaining patient care during cyber incidents. <a href="https://www.cyber-defence.io/services/incident-response">UK Cyber Defence</a> provides incident response planning including clinical downtime procedure development and testing.
Healthcare: Most Targeted Sector — Year Eighteen
Healthcare ransomware has appeared in this series in 2016, 2017, 2020, 2021, 2022, 2024, and now 2026 — making it the most consistently targeted sector across eighteen years. <a href="/cyber-essentials">Cyber Essentials</a> provides the baseline that every healthcare organisation must implement.
Lessons

Ransomware targets essential services. Defend them accordingly.

BridgePay and UMMC reinforced that ransomware consistently targets the services people depend on most — government operations and healthcare. Cyber Essentials provides the baseline. Penetration testing validates defences. SOC in a Box monitors essential services 24/7. And UK Cyber Defence provides the incident response and downtime planning that keeps essential services operational during attacks.

Breach #150. In May-June 2021, ransomware struck two critical infrastructure sectors simultaneously. On 14 May, Conti ransomware devastated Ireland's Health Service Executive (HSE), forcing hospitals to cancel thousands of appointments, revert to paper records, and delay cancer treatments — with full recovery taking over four months and costing an estimated €100 million. On 30 May, REvil ransomware hit JBS — the world's largest meat processing company — forcing closure of plants in the US, Canada, and Australia, and triggering fears of food supply disruption. JBS paid $11 million in ransom. Two critical sectors. Two weeks apart. The ransomware epidemic against essential services had reached crisis proportions.

Breach #142. In October 2020, the London Borough of Hackney was hit by a serious cyber attack — later confirmed as Pysa ransomware — that devastated the council's IT systems and disrupted services to approximately 280,000 residents for months. Housing benefit payments were delayed, planning applications could not be processed, land registry searches stalled, and council tax records were inaccessible. The full recovery took over two years. The ICO subsequently fined Hackney Council £120,000. The attack was the most severe ransomware incident to hit a UK local authority.

Anatomy of a Breach: Düsseldorf University Hospital — The First Ransomware-Linked Death

Breach #141. In September 2020, Düsseldorf University Hospital in Germany was hit by ransomware that encrypted 30 servers and forced the hospital to deregister from emergency care. A woman requiring emergency treatment was diverted to a hospital 30 kilometres away and died during the delay. German police investigated the case as negligent homicide — the first known instance of a death directly linked to a ransomware attack. The ransomware exploited a known Citrix VPN vulnerability (CVE-2019-19781) that had been patched nine months earlier. The case that proved ransomware against healthcare can kill.
