Ransomware is no longer a sporadic cyber threat. It is a scaled, structured criminal industry and it is accelerating.
Cyble recorded 6,604 ransomware attacks in 2025, representing a 52% increase on 2024. The year ended at near-record levels, with 731 ransomware attacks recorded in December 2025 alone. Supply chain attacks also surged, rising 93% year on year, from 154 incidents in 2024 to 297 in 2025 [BackBox - Ransomware and Supply Chain Attacks Soared in 2025 - 2026].
The Russian-linked group Qilin led all ransomware groups in 2025 with 1,138 victims, including 190 in December and a further 115 in January 2026. Meanwhile, the United States accounted for 55% of global ransomware attacks in 2025. Cyber Security analyst Paul Shread warned that the threat landscape remains “perilous” heading into 2026, reinforcing the need for renewed focus on cyber security best practices [TechRepublic - Ransomware Attacks Surge in 2025 - 2026].
The direction of travel is clear. The threat landscape is not stabilising. It is intensifying.
3 structural shifts are driving the surge.
Cybercrime now operates like a franchise model. Toolkits, infrastructure and negotiation playbooks are packaged and sold to affiliates. This lowers the technical barrier to entry and increases attack volume while maintaining sophistication.
Rather than targeting organisations individually, threat actors compromise trusted vendors and service providers to gain downstream access. A single breach can unlock dozens of victims.
Modern ransomware rarely begins with obvious malware, it often starts with stolen credentials, session hijacking and privilege escalation within Microsoft 365 and cloud environments.
If identity is weak, attackers do not need to break in. They log in.
Organisations with 200 to 5,000 users sit in a dangerous middle ground:
Many have invested in security tooling, but fewer have operationalised it effectively.
Technology alone does not stop ransomware. Visibility without rapid response still results in a breach.
Most successful attacks exploit gaps in monitoring, identity governance and response speed rather than the absence of tooling.
Backups matter. Incident response plans matter. Cyber Insurance matters. But these are recovery mechanisms, not prevention strategies.
The real cost of ransomware extends far beyond the ransom payment:
A prevention-first strategy is materially more cost-effective than breach recovery.
In 2026, the critical question is not whether you can recover. It is whether you can reduce breach probability in the first place.
That requires:
CyberOne delivers performance-led cyber security built around Microsoft’s integrated security ecosystem. The objective is not tool sprawl. It is a measurable risk reduction aligned to business outcomes.
Microsoft Entra forms the control layer. Through Conditional Access, Multi-Factor Authentication, Privileged Identity Management and identity governance, the most common ransomware entry points are reduced.
If privilege escalation is contained, large-scale encryption cannot propagate. Identity is critical infrastructure.
Microsoft Defender for Endpoint provides behavioural detection, attack surface reduction and automated containment. Suspicious activity is isolated quickly to prevent lateral movement.
This reduces dwell time and limits blast radius.
Defender for Cloud and Defender for Cloud Apps provide continuous visibility across Azure and Microsoft 365 environments. Misconfigurations and abnormal behaviours are identified before they become pathways to breaches.
Defender for Office 365 reduces phishing, malicious links and credential-harvesting attempts, yet remains the primary initial access vector for ransomware groups.
Security controls are only effective if continuously monitored.
CyberOne’s Managed Microsoft Security services, Assure365, provide round-the-clock monitoring, triage and human-led incident response. AI-driven detection is combined with expert analysis to deliver:
Security posture is continuously reviewed and optimised, not left static after deployment.
With supply chain attacks rising sharply, implicit trust is no longer viable. CyberOne helps organisations implement Zero Trust architecture using Microsoft capabilities, ensuring:
Trust must be continuously validated, not permanently assumed.
The ransomware growth trajectory is clear; attackers are scaling operations, refining techniques and targeting identity and cloud environments with precision. Mid-market organisations cannot rely on fragmented controls or reactive playbooks.
Enterprise-grade security, delivered efficiently and aligned to Microsoft’s ecosystem, is now the minimum requirement for resilience.
6,604 attacks in a single year is not just a statistic. It is a clear warning. The organisations that will lead in 2026 will not be those that recover fastest. They will be those who prevent more, detect earlier and respond decisively.
Ransomware is scaling. Your defence strategy must scale faster.
