“We have to be aware that war has many forms, and we must be prepared,” a senior European Union official warned this week as a wave of hybrid aggression ripples across the continent.
From manipulated supermarket refrigeration units to a surge in hoax bomb threats grounding commercial flights, Europe is facing a coordinated campaign of destabilization that exploits the very infrastructure that keeps its economy breathing.
The disruption began in the early hours of October 12, when silent alarms flickered to life in dozens of French supermarkets. Hackers had seized control of industrial temperature-control systems, forcing freezers and refrigerators to maximum heat.
The result was thousands of euros in spoiled inventory and a clear signal: the digital walls surrounding the food supply chain are thinner than once believed. Similar incidents soon followed in Belgium, Ireland, Sweden, Estonia, Luxembourg, and Finland.
The aggression has since evolved into a campaign of psychological warfare. Thousands of Italian schools were forced to evacuate this week due to anonymous bomb threats, while across the continent, commercial aviation has been thrown into chaos. Eurocontrol ha contabilizado al menos 35 aviones afectados en unos 20 aeropuertos. The European Commissioner for Transport, Apostolos Tzitzikostas, confirmed between 40 and 45 such threats against commercial flights in a single week.
The Grey Zone Strategy
Italian Defense Minister Guido Crosetto described the situation as a war fought “below the threshold,” a calculated strategy designed to blur the lines of attribution. “Everything is connected: the refrigerators, the blood banks in France, the drones, the aircraft, the threats. This is the era we have to live in,” Crosetto stated after the school evacuations. He added, “We will have to get used to it.”
The complexity of identifying the culprits reflects the shifting nature of modern statecraft. While France has officially blamed Iran’s Islamic Revolutionary Guard Corps for the supermarket attacks and signaled its intent to push for international sanctions, the diplomatic consensus remains fractured. In Belgium, Interior Minister Bernard Quintin initially pointed to Iranian involvement, though Foreign Minister Maxime Prévot later urged caution, noting that current evidence remains inconclusive.
Simultaneously, digital footprints suggest the involvement of Kremlin-linked actors. Two hacker groups, NoName057(16) and Z-Pentest, claimed responsibility for the refrigeration attacks. Italian aviation authorities reported that some of the hoax bomb emails were signed by a Russian supremacist group. As Tim Bosch, a former Dutch intelligence officer and current security consultant, observed, “If it walks like a duck and quacks like a duck, it is probably a duck.”
Digital Interconnectivity as a Security Liability
These hybrid operations exploit the profound interconnectivity of the European market. A report from the European Union Agency for Cybersecurity (ENISA) highlighted that 8,257 security incidents were recorded in 2025, with more than half driven by ideological motivations. The report warns that the distinction between state-sponsored spies, digital activists, and common criminals is rapidly dissolving as these groups share methods and infrastructure.
Recent systemic failures further exposed the vulnerability of this hyper-connected network. A Microsoft server outage left Dutch municipal governments and British hospitals struggling to manage basic services, while a separate telecommunications fault forced the U.S. Federal Aviation Administration to ground flights for over four hours.
These technical failures serve as a backdrop to the hybrid attacks, proving that service disruptions can be triggered by both accidental glitches and intentional sabotage.
“The current tactics of the grey zone exploit the way our economies are connected,” says Elisabeth Braw, a senior fellow at the Atlantic Council. This interconnectedness means that no sector is truly isolated. If today’s target is a cooling system in a French grocery store, tomorrow’s target could be the household routers that connect citizens to the internet or the power grids that sustain urban life.
The Challenge of Escalating Instability
The timing of this campaign is not coincidental. As the conflict in Ukraine remains deadlocked, European intelligence officials see a clear escalation in Russia’s hybrid efforts. From flying explosive-laden drones into German airports to targeting national blood banks, the goal is to erode public confidence in the state’s ability to protect its citizens.
“The enemies of the European project are digging to find vulnerabilities and exploit them,” one European intelligence official noted on the condition of anonymity. “They don’t even have to create a crack; they just have to exploit the ones that are already there. And they will do whatever it takes to try to destabilize Europe.”
As national authorities scramble to harden their digital defenses, the reality of the situation remains sobering. The continent has moved from a period of digital optimism to one of systemic fragility, where the convenience of a “smart” society has effectively handed adversaries a map of the most effective pressure points.
Authorities continue to investigate the source of the recent hoax messages, but as the incidents continue to mount, the question is no longer who is behind the latest attack, but how much more chaos the public can endure before the cumulative effect forces a fundamental change in European security policy.
“These attacks are part of a strategy to increase chaos,” said Crosetto. “We will have to get used to it.”
