Russian hacktivists DDoS’ed several hospital websites across the US and the Netherlands were down.

University of Michigan Hospital and Stanford Health Care Center were among the targeted facilities in the current campaign, which hit a handful of hospitals in the US

These wave of attacks was reportedly launched in response to President Biden’s decision to send dozens of Abrams tanks to help the war effort in Ukraine.


A hospital in the northern Dutch city of Groningen has also come under fire from suspected Russian hacktivists.

University Medical Center Groningen (UMCG) has seen its website flooded with traffic, although no medical services are thought to be affected.

At this time, it’s not clear if any other Dutch hospitals have been impacted, although the country’s healthcare computer emergency response team, Z-CERT, attributed the UMCG attack to Killnet.

The Netherlands has not agreed to send tanks to Ukraine as it currently does not own any outright, though it leases the equipment from Germany.


Killnet has been a supporter of Russia’s war in Ukraine, using DDoS attacks as its primary weapon to disrupt operations in allied countries. Last week, it hit several Lithuanian government websites, while in October last year, it struck the websites of over a dozen US airports.
