The Croatian public university hospital KBC Zagreb suffered a cyberattack from the LockBit ransomware group, forcing the institution to restore its IT systems with the help of more than 100 experts.
On Thursday, the LockBit group attacked the KBC Zagreb hospital, disabling its networks and forcing patients to be redirected to other hospitals in the city. Patient safety was not at risk, the hospital said, but the radiology system, which is particularly dependent on information support, suffered the most damage. LockBit said it stole a large number of files, including medical records, research papers, transaction data, legal documents and more. The hospital notified the relevant authorities and the police launched an investigation.
Operating on a ransomware-as-a-service (RaaS) model, LockBit has been involved in more than 1,400 attacks since its inception in late 2019. The group regularly attacks critical infrastructure around the world. In 2020, LockBit carried out a major attack on SolarWinds and was also involved in numerous attacks on government institutions, banks and other important facilities.
The attack on KBC Zagreb highlights the need for increased security and monitoring of IT systems of medical institutions. LockBit continues to threaten the global infrastructure, and the fight against such cyber attacks is becoming more and more urgent.
