Major Healthcare Data Breach Exposes 458K Patient Records

Swiss Medical, a major Argentine healthcare provider, suffered a significant data breach resulting in approximately 458,000 patient records being stolen and offered for sale on dark web marketplaces. The incident exposes highly sensitive healthcare information, creating substantial privacy risks for patients and potential regulatory violations.
