In September 2026, reports emerged that Mankato Clinic, a multispecialty healthcare provider in Minnesota, may have suffered a data breach. The hacker group Chaos claimed on September 10, 2026, to have stolen 610 gigabytes of data. Mankato Clinic has not publicly confirmed or detailed the incident.
The specific types of data exposed have not been publicly disclosed, and there is no confirmed count of affected individuals. It remains unclear whether highly sensitive data such as SSNs, medical records, or financial information were compromised. Only Minnesota is explicitly tied to the clinic's operations.
No official breach notification letters, company statements, or State Attorney General filings confirming the incident have been located in the public record. Details about the breach, including affected individuals and data types, may emerge later as investigations or notifications progress.
