Danish Government and Defense Firms Hit by Major Cyberattack
The Danish government and several defense companies were targeted by a large-scale cyberattack, presumably by pro-Russian hackers, forcing their websites to be temporarily taken offline.
The Gaze reports on it, referring to European Pravda, citing AFP.
On Thursday, a number of Danish government and defense industry websites were hit by a DDoS attack that overloaded servers and blocked user access. The Danish Civil Protection Agency said it was monitoring the situation together with military intelligence and was currently assessing the scale of the incident.
The pro-Russian hacker group NoName057 claimed responsibility for the attack, saying that its targets were the Danish Ministry of Transport and the government portal Borger.dk. Representatives of the defense company Terma, whose websites were also affected, noted that no serious security breaches or data loss had been recorded, and that the company was prepared for such cyberattacks and responded quickly to the incident.
Experts warn that attacks of this type are becoming more frequent amid escalating geopolitical tensions in the region and stress the importance of continuously strengthening cyber security for government and strategic facilities.
Earlier, on August 12, several Danish energy institutions — including Elnet selskabet N1, Energinet, and the state agency Energistyrelsen — were targeted by pro-Russian hackers from the group Server Killers. The attacks, primarily large-scale DDoS operations, temporarily took the websites offline but did not disrupt the institutions’ operations.
It is suggested that the attacks were retaliatory, linked to Denmark’s participation in Europol’s Operation Eastwood in July 2025, which led to the arrest of members of the pro-Russian hacker group NoName057.
Denmark is facing a heightened risk of sabotage against its armed forces amid ongoing hybrid threats from Russia, according to Thomas Ahrenkiel, head of the Danish Defence Intelligence Service (FE).
“This means that Russia is using military means, including in an aggressive way, to put pressure on us without crossing the line into armed conflict,” he said.
As a reminder, Denmark has previously experienced incidents involving drone intrusions, which led to the temporary closure of airports in Copenhagen and Oslo. Prime Minister Mette Frederiksen noted that Russia's involvement in these attacks cannot be ruled out, and Western security services emphasize the growing threat of hybrid operations, including cyberattacks, espionage, and sabotage.
The Gaze reported earlier that, according to NATO Secretary General Mark Rutte said, Russia is actively conducting espionage and cyberattacks against Alliance member states in an attempt to undermine their security and support for Ukraine.
