Ransomware-as-a-Service (RaaS) is a criminal business model where cybercriminals rent out ransomware tools and infrastructure to affiliates who carry out attacks. This subscription-based approach has led to a 126% increase in ransomware attacks in the first quarter of 2025, with operators typically taking 20-30% commission from successful ransom payments.
Key Protection Methods:
- Implement offline backup systems that cannot be accessed through network connections
- Use network segmentation to isolate critical systems from general access
- Conduct regular employee training on sophisticated phishing techniques
Current RaaS Target Analysis
| Target Sector | Appeal to RaaS Operators | Average Ransom Demand |
| Healthcare | Critical services, patient safety concerns | £150,000 – £500,000 |
| Education | Limited security budgets, valuable research data | £50,000 – £200,000 |
| Manufacturing | Supply chain disruption potential | £200,000 – £1,000,000 |
| Professional Services | Sensitive client information | £100,000 – £400,000 |
How Does Ransomware as a Service Work?
RaaS operates like legitimate software-as-a-service platforms, complete with customer support, regular updates, and user-friendly interfaces. Criminal organisations develop and maintain ransomware tools, then rent access to affiliates who carry out actual attacks.
These platforms provide comprehensive packages including encryption software, payment systems, negotiation services, and public relations management for victim communications. Some RaaS providers offer 24/7 technical support to ensure affiliates can successfully deploy attacks.
The subscription model includes performance guarantees, with some providers offering refunds if attacks fail to generate expected results. This professional approach attracts numerous affiliates who view cybercrime as a low-risk, high-reward opportunity.
Is Ransomware as a Service Increasing?
Yes, RaaS has fundamentally altered how cybercriminals operate and target UK businesses. This model allows individuals with minimal technical expertise to launch sophisticated ransomware campaigns by purchasing access to professional-grade malware and supporting infrastructure.
The democratisation of cybercrime through RaaS platforms has led to a 126% increase in ransomware attacks during the first quarter of 2025 compared to the same period in 2024. This surge demonstrates how accessible criminal tools have expanded the pool of potential attackers.
RaaS operators typically retain 20-30% of ransom payments as commission, whilst affiliates keep the remainder, creating powerful incentives for developing increasingly effective attack methods.
Who Do Ransomware Criminals Target?
RaaS operators primarily target UK organisations with strong financial capabilities and critical operational dependencies. Healthcare trusts, local councils, educational institutions, and small-to-medium enterprises represent prime targets due to their limited cybersecurity resources and high recovery urgency.
Manufacturing companies and supply chain operators face particular risks, as attacks can disrupt entire industry sectors. The interconnected nature of modern business means that a single successful RaaS attack can cascade across multiple organisations.
Professional services firms, including legal practices and accounting companies, attract attention due to the sensitive client data they store. The reputational damage from data exposure often compels these organisations to pay ransoms quickly.
How to Protect Against Ransomware as a Service?
UK businesses can significantly reduce their vulnerability to RaaS attacks through comprehensive security strategies. However, the professional nature of RaaS operations means that traditional security measures alone are insufficient against these sophisticated threats.
Implementing robust backup and recovery systems remains the most effective defence against ransomware. Offline backups that cannot be accessed through network connections provide crucial insurance against encryption attacks.
Network segmentation limits ransomware spread by isolating critical systems from general network access. This approach ensures that even successful initial compromises cannot easily reach high-value targets.
Employee training programmes must address the sophisticated social engineering techniques used by RaaS affiliates, as many successful attacks begin with convincing phishing emails that bypass technical security measures.
Can Police Stop Ransomware as a Service?
Law enforcement agencies have achieved notable successes against major RaaS operations, but complete elimination remains extremely challenging. High-profile takedowns of platforms like Conti and DarkSide have disrupted criminal networks and recovered millions in ransom payments.
However, the decentralised nature of RaaS makes lasting impact difficult. When authorities shut down one platform, operators often migrate to new infrastructure within days or weeks.
The cat-and-mouse nature of cybercrime enforcement means that whilst individual operations may be disrupted, the underlying RaaS model continues to evolve and adapt to law enforcement pressure.
What to Do if Hit by Ransomware?
Immediately isolate affected systems to prevent further encryption by disconnecting from networks and shutting down systems. This decision requires balancing operational needs against security concerns, but quick action can limit damage significantly.
Report attacks to the National Cyber Security Centre and local police to provide valuable intelligence for law enforcement whilst potentially accessing support resources. Many organisations hesitate due to reputational concerns, but transparency often leads to better outcomes.
The question of whether to pay ransoms remains controversial. Whilst payment may provide immediate system recovery, it funds criminal operations and provides no guarantee that data will be restored or remain confidential.
Future of Ransomware as a Service
RaaS platforms will likely incorporate more artificial intelligence and automation throughout 2025, making attacks more efficient and harder to detect. These improvements will lower skill barriers for affiliates whilst increasing attack success rates.
Cloud-based RaaS infrastructure will become more prevalent, offering operators greater resilience against law enforcement actions. The shift to distributed architectures makes platforms harder to shut down completely.
UK businesses must recognise that RaaS represents a permanent shift in the cybercrime landscape rather than a temporary trend. Long-term security strategies must account for the professional, persistent nature of these threats.
