From supermarket fridges to passenger flights, a wave of threats is testing Europe's defenses

A wave of cyberattacks and bomb threats is testing Europe’s ability to protect critical infrastructure, with disruptions ranging from compromised supermarket refrigeration systems to widespread flight cancellations. The incidents have exposed vulnerabilities across sectors that underpin daily life and commerce, raising questions about how well-prepared governments and companies are for simultaneous, low-cost disruptions. The threats add pressure on regulators and operators to harden defenses and improve coordination across borders. What to watch next is whether authorities tighten cybersecurity and threat-response requirements for essential services, and whether businesses accelerate spending on resilience measures.
