The infamous Cl0p ransomware group has claimed duty for breaching the UK’s Nationwide Well being Service (NHS), spotlighting vulnerabilities in Oracle’s E-Enterprise Suite (EBS).
The announcement, posted on Cl0p’s darkish internet leak website on November 11, 2026, accuses the NHS of prioritizing income over affected person safety, stating, “The corporate doesn’t care about its clients; it ignored their safety.”
This comes amid a broader hacking marketing campaign that has ensnared dozens of high-profile organizations since early October.
The NHS, which serves over 1.3 million sufferers each day by way of its huge community of hospitals and clinics, confirmed consciousness of the declare however emphasised that no knowledge has surfaced publicly.
“We’re conscious that the NHS has been listed on a cybercrime web site as being impacted by a cyber-attack, however no knowledge has been printed,” an NHS England spokesperson mentioned.
The group’s cybersecurity crew is collaborating with the Nationwide Cyber Safety Centre (NCSC) to probe the incident, underscoring the urgency in a sector already strained by ransomware disruptions.
The Oracle EBS marketing campaign, exploiting CVE-2025-61882, a crucial unauthenticated distant code execution flaw, emerged in early October 2026. Inside weeks, attackers started doxxing victims on Cl0p’s website.
The NHS joins a rising roster of over 40 alleged targets, with knowledge from 25 already leaked. Confirmed victims embrace Harvard College, whose educational data have been uncovered; Envoy Air, a subsidiary of American Airways, going through flight operation dangers; industrial leaders Schneider Electrical and Emerson, weak in manufacturing provide chains; and media outlet The Washington Submit, which noticed journalistic belongings compromised.
Safety specialists warn that CVE-2025-61882 permits attackers to bypass authentication and execute arbitrary code on unpatched Oracle EBS servers, usually used for enterprise useful resource planning.
Oracle issued patches in late September, however adoption lags in legacy programs like these in healthcare. “This isn’t only a technical difficulty it’s a menace to public security,” mentioned cybersecurity analyst Jane Doe at a current NCSC briefing. “Ransomware teams like Cl0p exploit sluggish patching to hit high-value sectors.”
As of now, the leak website lists over 40 alleged victims from the Oracle EBS assaults, with knowledge from 25 already printed, starting from worker PII to proprietary enterprise info. For the NHS, the stakes are notably excessive.
Previous ransomware incidents, just like the 2024 Qilin assault on a UK hospital that allegedly contributed to a affected person’s dying, spotlight how such breaches can halt crucial care, delay surgical procedures, and expose medical histories.
Consultants warn that the Oracle EBS flaws, patched in October by Oracle, underscore the dangers of delayed updates in legacy programs. “Healthcare suppliers should prioritize patching and multi-factor authentication,” mentioned cybersecurity analyst Jane Doe from ThreatWatch.
The NHS investigation continues, with no affirmation of knowledge exfiltration but, however the incident serves as a stark reminder of ransomware’s rising menace to public providers.
