The University Hospital Centre Zagreb is under cyberattack that started on Wednesday night, the Croatian Radiotelevision has reported.

Because of the attack, the hospital has shut down its information system and will be switching parts of it online once they are sure it's safe to do so.

It is currently unknown whether the cyberattack against the hospital involved the deployment of ransomware, and whether it's connected to yesterday's DDoS attacks on the websites of several Croatian government and financial institutions: the Ministry of Finance, the Tax Administration, the Croatian National Bank, the Economic Bank of Zagreb, and the Zagreb Stock Exchange.

Given the current geopolitic situation, it's also possible that the cyberattack against the hospital is part of the recent Russian sabotage operations targeting European and NATO countries.

Vlatko Košturjak, CTO at Croatian infosec outfit Diverto, says that they have observed a slight increase in DDoS attacks on Croatian infrastructure since their decline in 2021.

"Despite being an older and well-known attack technique, DDoS remains a simple and cost-effective method for attackers to disrupt organizational operations. This uptick highlights the ongoing effectiveness of DDoS attacks, as defending against them requires a systematic approach and close coordination between internet service providers and organizations," he added.
