Ransomware remains one of the most persistent and damaging threats to organizations worldwide. According to the recent report from the ZIUR Industrial Cybersecurity Center, 1,951 ransomware incidents were detected globally during the fourth quarter of 2025, representing a 14.6% increase compared to the previous quarter.
This increase confirms that ransomware activity is not sporadic, but a sustained trend that threatens both large corporations and a diverse range of businesses. Supply chain-intensive sectors such as manufacturing, technology, healthcare, and consumer services have been among the most affected. This highlights that the proliferation of attacks continues unabated and keeps finding vulnerabilities in exposed systems.
In Spain, although the confirmed incidents (33) are a fraction of the global total, sectors such as transport and tourism showed a higher relative incidence, precisely because of their dependence on complex and highly interconnected technological ecosystems.
The nature of the observed attacks reflected a growing diversification of actors, moving from highly organized groups to more fragmented campaigns that exploit weak configurations, default credentials, or poor digital hygiene practices to infiltrate, encrypt data, and, in many cases, demand ransoms for its release.
Furthermore, the report emphasizes that this is not merely an isolated technical problem: both organizations and industrial sectors must adopt a comprehensive preventative approach that combines technology, processes, and awareness. Resilience is not built by reacting after an attack, but by anticipating it and reducing the attack surface before an incident occurs.
How CIBERIA helps prevent and combat ransomware
Faced with this persistent threat scenario, CIBERIA supports organizations in being able to prevent and confront attacks. Having robust defenses and early response capabilities can make the difference between a manageable incident and an operational disaster.
CIBERIA's SOC-T service is a key tool for addressing challenges like ransomware through features such as continuous 24/7 monitoring. This allows for the detection of anomalous behavior linked to malicious encryption attempts or lateral movement within the network before the incident spreads. Its configuration enables advanced detection and event correlation, helping to identify typical ransomware patterns even when attackers use sophisticated techniques to remain undetected. Therefore, in the event of an incident, the system will respond immediately, and with the support of one of our experts, operations will be restored quickly.
Resilience: A Strategic Investment
Ransomware doesn't just encrypt data: it can paralyze operations, damage reputations, generate significant financial losses, and compromise the trust of customers and stakeholders. Therefore, adopting a proactive defensive stance should not be seen as a cost, but as a strategic investment in business continuity and sustainability.
In 2025, with nearly 2,000 incidents in the last quarter alone, the evidence is clear: cybersecurity must be a cross-cutting priority that combines technology, processes, and people. CIBERIA represents a key pillar in this regard by supporting companies in Spain and Portugal in building more secure, resilient, and better-prepared organizations to face current and future threats.
