Russia Steps Up Sabotage Attacks on Danish Defense Firms, Intelligence Says

What is Russia accused of doing to Danish companies that supply military equipment to Ukraine?

Russia is accused of targeting Danish companies that supply military equipment to Ukraine. The alleged operations are part of a broader hybrid warfare campaign. They matter because Denmark is helping sustain Ukraine’s military effort, while Moscow is seeking ways to weaken Western support. PET analyst Josefine Christensen said Russia moved from planning to carrying out more operations in early summer.

The alleged targets include weapons producers and other firms connected to military supplies. Christensen said Moscow is now trying to hit targets with a direct effect on the front line. Russia’s Defense Ministry also published an April list naming European drone and drone-component manufacturers as potential military targets. Russia denies involvement, and its embassy in Copenhagen called Denmark’s claims unfounded.

PET says the campaign may use inexperienced proxies recruited online. These recruits can begin by photographing or observing targets, then attempt sabotage. Christensen said Russia may keep sending new people until one succeeds. The reported shift suggests Danish companies could face continued security risks as they support Ukraine.

What is hybrid warfare, and how does sabotage fit into it?

Hybrid warfare is a campaign that mixes different kinds of pressure instead of relying only on open combat. It can include sabotage, cyber activity, disinformation, coercion, espionage, or disruption of infrastructure. The goal is often to create fear, raise costs, weaken public confidence, or change an opponent’s decisions. In this article, Danish officials describe alleged Russian sabotage as part of such a campaign.

Sabotage is the physical part of that pressure. It can target factories, transport systems, airports, or other facilities. Christensen said Russia is focusing on weapons production because it directly supports Ukraine’s front line. The article also describes reconnaissance and photographing targets as early steps before a sabotage attempt. These activities can be carried out secretly and through proxies.

The Danish defense intelligence service expects Russia to intensify hybrid attacks against Western countries. Russia denies conducting sabotage or hybrid warfare. The reported use of untrained recruits makes attribution and prevention harder, while repeated attempts could still damage important facilities or disrupt support for Ukraine.

How extensive have Russia-linked disruptions in Denmark been, including the drone incidents that affected six airports in September 2025?

The reported disruptions reached six Danish airports in September 2025, including Copenhagen, the Nordic region’s busiest airport. The drones disrupted air traffic ahead of Denmark hosting an EU summit. Prime Minister Mette Frederiksen called the incident a hybrid attack against Denmark. This shows that disruption can affect civilian transport and national events, not only military sites.

However, the article does not say Russia was responsible for those drone incidents. It presents them as background while separately reporting PET’s accusations about Russian sabotage against Danish military suppliers. That distinction matters. The six-airport episode demonstrates the scale of one disruption, but it is not proof of a Russia-linked operation.

Denmark’s defense intelligence service said Russia was likely to intensify hybrid attacks against Western countries in the coming months. Germany also accused Moscow of an attempted drone attack at Leipzig/Halle Airport in August. Together, these cases have increased concern about further disruption, though responsibility must be established for each incident.

Why would damaging weapons production have a direct effect on the front line in Ukraine?

Weapons production is closely connected to battlefield capacity. Factories make or assemble the equipment that military forces need to fight. If production slows, stops, or becomes less reliable, supplies may arrive later or in smaller quantities. That can affect operations at the front line, where equipment is used directly. Christensen said Russia is deliberately seeking this kind of impact.

The article identifies Danish companies supplying military equipment to Ukraine as alleged targets. It also mentions Russia’s April list of European drone and drone-component manufacturers described as potential military targets. Drones and their components are especially relevant because they are part of the equipment used in the war. Sabotage would therefore target the supply chain rather than only battlefield positions.

Russia reportedly changed strategy after deciding that broader disruption had not deterred NATO from supporting Ukraine. The new focus is more selective and practical: strike producers or suppliers whose work supports Ukrainian forces. If the accusations are accurate, protecting these companies becomes important for maintaining Western military assistance.

Who are the proxies Russia is reportedly recruiting, and how are they being found through Telegram and other social media?

PET says Russia increasingly relies on untrained proxies rather than only trained operatives. The reported recruits include homeless people and people addicted to drugs. Christensen also said the pool could include anyone looking for quick money. This approach gives Russia access to people who may accept risky assignments for relatively small payments, while keeping the alleged organizers more distant from the target.

Recruitment reportedly begins on Telegram or other social media platforms. Recruits may first be asked to perform low-level tasks, such as watching a location or photographing a potential target. If they succeed, the work can escalate to sabotage. Christensen said an unsuccessful recruit may be replaced by another person until the operation works.

The article does not describe a single named recruiter or a specific recruitment post. It presents a pattern identified by PET. The use of inexperienced proxies may make operations less reliable, but repeated attempts can still create danger for companies and infrastructure. It also complicates efforts to identify who is directing the activity.

Why might Russia shift from broad efforts to disrupt Western support toward targeting companies that directly supply Ukraine?

Christensen said Russia concluded that broad targeting had not deterred NATO from supporting Ukraine. That judgment reportedly pushed Moscow toward a narrower strategy. Instead of trying mainly to create general disruption, Russia is accused of selecting companies whose work directly supports Ukraine’s military. The aim would be to increase the cost of assistance and weaken its practical effect.

The clearest example is the alleged targeting of Danish military-equipment suppliers. Christensen said Russia is trying to hit weapons production because it has a direct impact on the front line. Russia’s Defense Ministry also listed European drone and drone-component manufacturers as potential military targets in April. These examples point to supply chains as strategic pressure points.

The shift does not mean broader hybrid activity has ended. Denmark’s defense intelligence service expects Russia to intensify attacks against Western countries. It means the alleged campaign may combine general disruption with carefully chosen industrial targets. That could make security at factories and suppliers more important as Western support continues.

What is NATO, and why does its continued support for Ukraine matter to Russia's strategy?

NATO, the North Atlantic Treaty Organization, is a military alliance among member countries. In this article, NATO represents the Western military support that Russia wants to deter from continuing. Its support matters to Russia’s strategy because assistance to Ukraine helps sustain the country’s war effort. The article does not list specific NATO contributions, but it links the alliance directly to continued backing for Kyiv.

Christensen said Moscow concluded that earlier, broad targeting had not deterred NATO from supporting Ukraine. Russia is therefore accused of seeking more direct effects by targeting weapons production. Danish companies supplying military equipment are alleged to be among those targets. The logic is to pressure the practical supply of equipment rather than only create general fear or disruption.

The reported shift suggests that Russia may continue testing ways to weaken Western assistance. Denmark’s defense intelligence service warned that hybrid attacks against Western countries could intensify. Russia denies involvement in sabotage or hybrid warfare, so the allegations remain contested. NATO’s continued support is presented as the strategic pressure Russia is trying to change.
