Hackers have spent three weeks trying to break into the ICT environment of Gelre hospitals. They failed to loot privacy-sensitive data or other information. As a precaution, the healthcare institutions have increased the security measures.
Gelre Hospitals (Dutch: Gelre Ziekenhuizen) is a group of hospitals comprising hospitals in Apeldoorn and Zutphen, and an outpatient clinic in Lochem.
The way the incident is described, it does not sound like a major incident.
