Class Action Lawsuits Filed Following Ransomware Attack Impacting 1 Million Patients

A regional healthcare provider suffered a major ransomware attack in January 2025 that compromised the sensitive data of nearly one million patients, Bleeping Computer Reports.

The attack, detected on January 27, forced the organization to shut down parts of its IT systems and divert incoming ambulances to other emergency departments.  

A forensic investigation revealed that unauthorized access actually began on January 25, with attackers copying files from a file-sharing server. Stolen information varied by individual and included names, addresses, dates of birth, Social Security numbers, driver’s license numbers, health insurance details, and clinical care information.

Following the attack, the provider notified law enforcement, engaged cybersecurity experts, and began mailing letters to affected individuals. The breach was formally reported to the U.S. Department of Health and Human Services, which listed the number of impacted patients at 934,326.  

Although classified as a ransomware incident, no group has publicly claimed responsibility, raising speculation that a ransom payment may have been made.  

To assist those impacted, the provider is offering free credit monitoring, credit reports, and credit scores for twelve months. Affected individuals are urged to remain vigilant, monitor their credit reports, and take protective actions against potential identity theft and fraud stemming from the data breach.

The breach has led to multiple class action lawsuits against the healthcare provider. Plaintiffs allege that the provider failed to implement adequate cybersecurity measures and did not promptly inform affected individuals about the breach. The lawsuits seek damages exceeding $5 million, as well as injunctive relief to compel the provider to enhance its data security practices.

Takeaway: Let’s be real — the cost of responding to a ransomware attack is just the opening act. It’s the easy part. The real pain comes afterward: the brand damage, the sky-high cyber insurance renewals, the regulators breathing down your neck, and the lawyers lining up for class actions because sensitive or regulated data got out.

Most ransomware crews aren’t just locking up files anymore — they’re stealing the data first, setting you up for double extortion and double the fallout. If you’re sitting on PII, health records, financial info — anything regulated — you’re not just worried about downtime anymore. You’re staring down lawsuits, fines, and years of headaches.

And when the dust settles, every inch of your security program gets picked apart. Missed a patch? Forgot a config? That’s now Exhibit A in court. What used to be a “we’ll fix it later” becomes a “pay millions now” problem.

Everyone in security knows that if an attacker really wants in, they’ll find a way. That’s not being defeatist — it’s reality. But regulators and lawyers don’t care about reality — they care about accountability.

Today, getting hit with ransomware isn’t the end of the crisis — it’s the start of a long, brutal, and expensive second chapter. Better know what you’re sitting on.
