A group of Nigerian hackers breached the UnitedHealthcare database to steal more than six terabytes of confidential health records and private information of 120 million Americans registered with the insurance company, according to court filings seen by Peoples Gazette.

In a series of coordinated cyber attacks against UnitedHealthcare, the hackers broke into the company’s computer systems in February 2024. They stole the names, addresses, emails, and social security numbers of registered clients who are now seeking redress in court.

Scores of Americans have filed a class action lawsuit against the company before the U.S. District Court for the District of Minnesota, saying their private health data was stolen following a 2024 database breach.

The hacking started on February 21, 2024, according to the lawsuit filed on January 15, 2025.
