Europe greyzone attacks risks

Highlights

Suspected greyzone attacks disrupted supermarket freezers across Finland and Ireland, causing defrosting, temperatures up to 50C, and food losses worth millions of euros.
Additional attacks targeted French blood-bank refrigeration and triggered hoax bomb threats that forced airliner diversions, emergency landings, and fighter-jet escorts across Europe.
Sales of emergency preparedness goods surged after the UK government's Be Ready campaign, with Robert Dyas radio sales up 160% and Maplin torch sales nearly quadrupling.

Cross-sector disruption highlights new vulnerabilities

As reported by The Guardian, suspected greyzone attacks this week hit supermarket freezers, commercial aviation and blood-bank refrigeration systems across Europe, underlining how digitally connected infrastructure is opening fresh points of failure for retailers and other operators.

Supermarket freezers from Finland to Ireland reportedly switched from freezing to defrosting, in some cases reaching 50C and forcing stores to discard food worth millions of euros. The article says Russian hacktivists claim responsibility for some of the sabotage, though attribution remains unclear and other state-linked or unaffiliated actors could also be involved.

In Sweden, some of the affected stores had not linked their freezer systems to national retail networks with centralized protection, exposing a weaker layer of cyber defence. The incidents come as companies have already strengthened payment and logistics systems after costly ransomware episodes, suggesting attackers are now probing less protected operational technology.

Other disruptions this week include attempts to interfere with refrigeration at French blood banks and hoax bomb threats that force airliners across Europe to divert, make emergency landings or receive fighter-jet escorts. The broader pattern also includes suspected arson, drone incursions, GPS interference over the Baltic Sea, damage to subsea cables and pipelines, and repeated disinformation activity.

Preparedness spending gains urgency across Europe

The incidents are reinforcing a wider European debate over resilience planning for households, businesses and essential services. The UK government's Be Ready campaign, launched last month, is presented as part of that shift, offering guidance on emergency preparation for crises linked to climate risks or state-backed terrorism.

Evidence cited in the article suggests public demand for preparedness goods is already responding. Retailer Robert Dyas reports weekly radio sales jump 160% within a week of the campaign's launch, while Maplin says radio sales nearly double, power-bank sales more than double and torch sales rise to almost four times normal levels.

Sweden's long-running civil preparedness model is described as more comprehensive, with official guidance sent to households covering civil defence duties, volunteering, home supplies and ways to verify whether a crisis warning is genuine. The argument is that visible resilience can reduce the strategic value of sabotage by limiting panic and making disruption less effective.

For businesses, the warning is broader than cyber security alone. The article points to food inflation and oil and fertilizer shortages tied to disruption around the Strait of Hormuz after U.S. airstrikes, and argues that future attacks on ports, shipping routes, power, water or subsea data cables could create severe knock-on effects for industrialized economies that depend on complex imports and digital connectivity.

Cybersecurity and privacy startup funding surged in Q3 as larger late-stage rounds pushed total investment to $6.8 billion even while overall deal counts fell, our publication previously reported. We highlighted how AI-focused and identity-security companies attracted the biggest checks, alongside continued consolidation through major acquisitions—signalling that spending priorities are increasingly shaped by escalating digital threats.
