Healthcare Ransomware Attack Disrupts Operations | Meaden & Moore

Written by John Balsamo, CPA | Feb 26, 2026 6:30:00 PM

A large academic healthcare provider in Mississippi recently experienced a ransomware attack that significantly disrupted operations across its network.

Following the incident, approximately three dozen outpatient clinics were closed and elective medical procedures were cancelled while the organization evaluated the extent of the intrusion and worked to restore affected systems. Officials reported that multiple internal platforms — including electronic medical record functionality — were impacted, requiring staff to temporarily rely on manual documentation processes.

Emergency and hospital care remained available; however, many patients with scheduled services experienced delays. Some individuals traveled long distances only to learn appointments could not proceed, and the organization began contacting patients requiring time-sensitive treatment to reschedule services.

At the time of reporting, investigators were still determining whether sensitive patient information had been accessed. The organization confirmed it was working with federal law enforcement while simultaneously attempting to restore network functionality.

The situation illustrates how ransomware attacks increasingly target organizations whose operations cannot easily pause. Healthcare systems, public infrastructure, manufacturers, and service providers face similar exposure because attackers recognize that operational disruption creates immediate pressure.

More Than a Data Breach

Cyber incidents are often described as “data breaches,” but this event demonstrates a different reality — ransomware attacks are operational shutdown events.

Even when emergency services remain functional, the inability to access systems can halt:

    • scheduling
    • billing and receivables
    • diagnostic and reporting systems
    • financial processing
    • time-sensitive services

Organizations may continue operating at a limited level, but core processes slow dramatically. In many cases, employees revert to manual workflows, creating backlog, delays, and additional costs long after systems are restored.

The Financial Impact Often Lasts Longer Than the Attack

The immediate concern in any cyber event is restoring systems and protecting data. However, the longer-term challenge is understanding the financial consequences.

A cyber incident can create multiple categories of loss, including:

    • lost revenue due to suspended operations
    • overtime labor and backlog processing costs
    • system restoration and remediation expenses
    • customer or patient attrition
    • contractual or regulatory exposure
    • reputational harm

For organizations with cyber insurance, documenting and supporting these losses is essential to recovery. Insurers and legal stakeholders require detailed, defensible financial analysis to evaluate claims.

Where Cyber Risk Forensic Accounting Comes In

After a cyberattack, technical response teams focus on containment and system restoration. At the same time, organizations, insurers, and counsel need to determine the economic impact of the event.

Why Preparation Matters

Ransomware incidents are occurring with increasing frequency and sophistication. Organizations often prepare technologically but not financially.
