Danish authorities have publicly blamed Russia for cyberattacks on a Danish water utility company in 2024 and 2025, which caused denial of service outages and temporarily left thousands of homes without water. The attacks are considered part of Russia's broader "hybrid war" campaign against the West, aiming to destabilize critical infrastructure. Denmark's cybersecurity authorities stated that Moscow was behind the attacks, which also targeted another water facility. The water utility, the Tuse Valley Waterworks located southwest of Copenhagen, suffered service disruptions lasting up to one hour, affecting water pressure for about 60,000 households. Danish officials expressed concerns about the country's readiness to handle such cyber threats. The attacks were described as "destructive and disruptive," and examined in the context of wider European hybrid-warfare and disinformation campaigns orchestrated by Russia. The Danish Defense Intelligence Service released the findings, and the Danish Security and Intelligence Service (DSIS) indicated that there have been at least 147 similar incidents across Europe, many attributed to Russian actors. Denmark summoned the Russian ambassador over the attacks. German officials connected the cyberattacks to broader Russian hybrid warfare targeting Europe, including a 2024 cyberattack on German air traffic control. Danish political groups have distanced themselves from pro-Russia narratives. Officials stressed the vulnerability and ongoing threat posed by Russian cyber operations against Western infrastructure.
