NextFin news, Russian President Vladimir Putin has intensified hybrid warfare against Europe, causing widespread disruptions across several countries during the past week, according to reports from September 27, 2025. The tactics include drone incursions over airports, cyberattacks, and ambiguous sabotage activities, primarily affecting Denmark, Poland, Estonia, and other NATO members.
On Thursday and Friday, Danish airports, including Copenhagen and Aalborg, were forced to close temporarily due to suspected drone activity. Danish Prime Minister Mette Frederiksen warned that Europe should prepare for “more violent and frequent hybrid attacks” as a new reality, highlighting the threat without explicitly naming Russia as the culprit, though officials consider Moscow the main threat. The head of Denmark’s internal security police, PET, stated that the risk of Russian sabotage in Denmark remains high.
Poland reported over 19 violations of its airspace by Russian drones, prompting the scrambling of fighter jets and heightened alert of Patriot missile defense systems. Estonia experienced a 12-minute breach of its airspace by Russian MiG-31 fighter jets, an incident described by a top US general as either poor pilot training or a deliberate expansion of Russian aggression. These incursions have raised alarm among NATO allies, who are considering stronger defensive measures.
In addition to aerial threats, Europe has faced cyberattacks that paralyzed flights and disrupted infrastructure, further complicating the security environment. The ambiguity surrounding the perpetrators complicates responses, as European officials weigh the risks of misattribution against the need to bolster defenses and maintain public trust.
European nations, particularly those on NATO’s eastern flank, are responding by enhancing their defense capabilities. Denmark is supplying Ukraine with F-16 fighter jets, assisting in drone development, and acquiring long-range missiles. Several countries are collaborating to build a multi-layered “drone wall” defense system to detect and intercept rogue drones without costly fighter jet deployments.
Western officials face a dilemma in addressing hybrid warfare: publicly blaming Russia risks escalating tensions and feeding Moscow’s strategic aims, while downplaying the threat could leave societies unprepared for potential escalation. The hybrid warfare campaign imposes tangible costs on European civilians, including airport delays, rising energy prices, and increased security expenditures.
Despite these gains for Putin in spreading instability and pressure across Europe, the hybrid warfare strategy carries significant risks. There is potential for accidental civilian casualties in NATO countries, which could provoke a disproportionate military response. Additionally, the blurred lines between state-sponsored sabotage and organized crime complicate attribution and response efforts.
U.S. officials have urged Europe to strengthen its own defense posture amid these challenges. NATO allies have warned Moscow that further airspace violations could be met with force, including shooting down Russian aircraft, a stance that Moscow has threatened would lead to war.
Overall, Russia’s hybrid warfare campaign tests Europe’s unity, resilience, and readiness to adapt to new security threats. The ongoing conflict in Ukraine and the expansion of hybrid tactics to Europe’s doorstep underscore the complex and evolving nature of modern warfare in the region.
