What happened
Pro-Russian cyber actors manipulated operational controls at the small Tureby–Alkestrup drinking-water utility, changing network pressure and causing pipes to burst. Denmark's cyber-security authority reported that about 450 households briefly lost water because of low pressure and around 50 were without water for several hours after increased pressure ruptured a pipe. In December 2025, Denmark's Defence Intelligence Service attributed the destructive attack to Z-Pentest, assessed the group as linked to the Russian state, and described it as an instrument of Russia's hybrid campaign against Western countries supporting Ukraine. The marker is approximate.
