Pro-Russia hacking group Killnet has been targeting hospitals in Europe and the USA in retaliation for western support for Ukraine. The Netherlands National Cybersecurity Centre (NCSC) reported that the attacks impacted several hospitals in the country, but their impact was minimal. The Dutch cyber watchdog also said all the threats had been successfully mitigated. 

The US Department of Health and Human Services (HHS) also reported that Killnet had targeted US hospitals and is actively threatening the health and public health sector. The HHS noted that these attacks do not cause significant harm but can create service disruptions that may last several hours or days.

Hospitals in other European countries, including the UK, Germany, and Poland, have also been targeted.
