Denmark's Defense Intelligence Service revealed Thursday that Russia conducted cyberattacks on Danish infrastructure in 2024 and 2025, including a destructive attack on a water utility that caused pipes to burst near Køge, leaving homes without water. Russian hackers also targeted Danish websites with denial-of-service attacks ahead of November's regional elections.

Authorities linked the attacks to pro-Russian groups Z-Pentest and NoName057(16), calling them part of Russia's "hybrid war" against Western nations supporting Ukraine. Minister Torsten Schack Pedersen warned the incidents expose Denmark's vulnerability to such threats. The attacks join 147 documented incidents across Europe that officials attribute to Russia's broader sabotage campaign since invading Ukraine.
