Summary: Most Targeted Sectors by Ransomware in 2025

Ransomware remains one of the most critical cyberattacks for businesses and organizations. In 2025, far from decreasing, this threat has grown in sophistication, customization, and operational and economic impact.

Sector analysis shows that attacks are not distributed evenly: certain sectors carry the highest risk, becoming priority targets for cybercriminals both in Spain and globally.

Most Targeted Sectors in Spain

In Spain, the Manufacturing and Industrial sector leads ransomware attacks in 2025, accounting for over 34% of incidents. Its high exposure is due to low tolerance for downtime and the digitization of OT systems, making it a strategic target.

Consulting, Professional Services, and Healthcare sectors also face elevated risk due to the need to quickly recover critical data and services. Technology and Financial Services stand out because of their digital dependence, where an encryption event can cause immediate economic losses and reputational damage.

Most Targeted Sectors Globally

Globally, Manufacturing and Industrial remains the most affected sector by ransomware in 2025, accounting for 25% of attacks. Its heavy reliance on automated processes and the critical impact of any disruption in the supply chain make it a strategic extortion target.

Healthcare and Technology sectors occupy the next level of risk, with 15% and 12% of attacks respectively, due to the value of sensitive data and intellectual property. Other sectors such as Financial Services, Logistics, and Energy remain exposed, where digitalization and the critical nature of their infrastructures make them key targets for cybercriminal groups.

Impact of Ransomware Attacks by Sector

Manufacturing and Industrial: an attack can paralyze production lines and the supply chain, generating economic losses for every hour of downtime. The digitization of OT systems makes rapid restoration of critical processes essential.

Healthcare and Consulting/Professional Services: information hijacking compromises sensitive data and can block essential services, affecting patient and client trust.

Technology and Financial Services: dependence on digital systems makes any encryption event an immediate economic and reputational risk. Attacks can halt platforms and compromise strategic intellectual property.

Logistics, Energy, and Critical Infrastructure Operators: attacks can stop control systems, delay operations, and generate direct losses, affecting clients and partners.

Globally, Manufacturing and Industrial remains the most targeted sector, followed by Healthcare and Technology, where the value of data and the criticality of processes increase pressure on organizations. Sectors such as Financial Services, Logistics, and Energy remain strategic targets due to digitalization and the critical nature of their systems.

Ransomware Trends and Sector Impact

Ransomware attacks are increasingly targeted and aim to compromise critical systems and strategic data. They not only encrypt information but also paralyze operations and generate economic and reputational losses.

A single incident can halt production, block essential services, or affect key platforms, with direct impact on clients and partners.

Protection requires prioritizing backups, access monitoring, system updates, and staff training to ensure operational continuity against increasingly sophisticated threats.
