The University Hospital Centre Zagreb (KBC Zagreb) is under cyberattack that started on Wednesday (June 26) night. All services are working, but the processing of patients is slower than usual, Milivoj Novak, Assistant Director at the hospital, has said.

The attacks have been claimed by the pro-Russian NoName057(16) hacker group and have resulted in a temporary unavailability of the institutions’ websites and online portals. The sites are back online now.

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 (HNB), the Economic Bank of Zagreb (PBZ), and the Zagreb Stock Exchange (ZSE).
