Poland probes MyDr healthcare software breach potentially affecting 19 million people

Polish healthcare software vendor MyDr was the target of an external criminal cyberattack that may have exposed historical records for nearly 19 million people and data from more than 12,000 medical facilities; Polish authorities are investigating, MyDr has removed the intrusion and implemented additional security measures, and the e-Health Center is rotating certificates as a precaution. Officials report no evidence so far that stolen data was published or that national e-health systems were compromised, and the incident has not been attributed to a specific threat actor.
