The 42-page Medtronic data breach lawsuit contends that the company recklessly disregarded consumers’ privacy rights by failing to have in place adequate cybersecurity measures to protect the personally identifiable information (PII) and protected health information (PHI) in its care. Per the suit, names, addresses, medical histories, billing information, health insurance details, demographic information and Social Security numbers were compromised in last month’s Medtronic cyberattack.

According to the complaint, the April 2026 data breach, credited to the cyberhacking group ShinyHunters, was the “direct and proximate result” of Medtronic’s failure to implement reasonable data security practices, including those recommended for businesses by the Federal Trade Commission.

The incident reportedly exposed over nine million records containing sensitive information, the suit says. The lawsuit claims that Medtronic has yet to determine which individuals were impacted, and stated in an April 24 press release that it was still investigating whether patient data was affected.

“Despite all the publicly available knowledge of the known and foreseeable consequences of disclosure of PII and PHI, Medtronic’s policies and practices with respect to maintaining the security of Class Members' PII and PHI were reckless, or, at the very least, negligent,” the filing states.

The lawsuit argues that the exposure of someone’s private information to cybercriminals can leave them susceptible to identity theft, medical and financial fraud for years to come.

Misuse of a consumer’s information can be incredibly difficult to detect and resolve, particularly when Social Security numbers are involved, and may enable cybercriminals to create fake insurance claims, file fraudulent tax returns, file for unemployment benefits or publish the information for sale on the dark web, the case stresses.

Despite Medtronic’s representations that it maintains robust data privacy and security safeguards for its patients and employees, these measures were inadequate, especially given that healthcare entities are high-risk targets of cyberattacks, the complaint argues.

“By obtaining, collecting, using, and deriving a benefit from Plaintiff’s and Class Members PII and PHI, Medtronic assumed legal and equitable duties and knew or should have known that it was responsible for protecting Plaintiff’s and Class Members PII and PHI from disclosure,” the complaint asserts.

The plaintiff, a California resident, says she provided sensitive information to Medtronic in connection with receiving a heart monitor device in early 2026. The plaintiff claims that since the breach, she has experienced an increase in spam calls and text messages and faces a “substantially increased risk” of fraud and identity theft.

The lawsuit notes that since the data breach, Medtronic has announced no specific changes to its data security practices and policies or addressed the vulnerabilities in its systems that were supposedly exploited by the cyberhackers.

The Medtronic data breach lawsuit looks to represent all individuals in the United States whose personally identifiable and/or protected health information was exposed during the data breach disclosed by Medtronic on or around April 24, 2026.
