Danish water infrastructure attacked by pro-Russian hacker group.

In late 2024, the pro-Russian group Z-Pentest attacked the Tureby Alkestrup Waterworks, manipulating water pressure and causing pipes to burst, temporarily leaving around 50 households without water for seven hours and about 450 homes without water for one hour. Denmark’s Defence Intelligence Service said the group had links to the Russian state and described them as instruments of Russia’s hybrid war against the West. The Danish government subsequently summoned Russia’s ambassador, while authorities stressed that although the attack caused limited physical damage, they demonstrated the ability to disrupt important parts of Danish society.
