Ransomware-as-a-Service: Why It’s Booming

Ransomware used to be the domain of highly skilled hackers, today, anyone with bad intentions and a credit card can launch an attack. The rise of ransomware-as-a-service (RaaS) has turned ransomware into a thriving criminal business model, and SMBs are among the biggest targets.

At Commercial Networks, we help SMBs strengthen SMB cyber security defences and recover quickly if ransomware strikes. Understanding why RaaS is booming is the first step in protecting against it.

Ransomware-as-a-Service: What It Is

Ransomware-as-a-service works much like a legal subscription model. Instead of building malware themselves, attackers rent ready-made ransomware kits from criminal operators. These services often include:

Malware variants with ongoing updates.
Management dashboards for tracking victims.
Payment processing through cryptocurrency.
Even “customer support” to help criminals launch campaigns.

The result? A lower barrier to entry, meaning more attacks from less skilled cybercriminals. According to Europol’s Internet Organised Crime Threat Assessment 2025, RaaS has fuelled a surge in ransomware incidents across Europe, with SMBs disproportionately affected.

Why Ransomware-as-a-Service Is Booming

Several factors explain the growth of RaaS:

Profitability – ransomware remains one of the most lucrative forms of cybercrime.
Accessibility – dark web marketplaces make it easy to buy ransomware kits.
Affiliate models – RaaS providers share profits with attackers, incentivising more campaigns.
Automation – AI tools are now used to generate phishing lures and automate attacks.
Global reach – criminals can target businesses anywhere with little risk of prosecution.

The National Cyber Security Centre warns that ransomware groups are becoming more professional, using business-like structures to expand operations.

The SMB Impact

For SMBs, the rise of RaaS is bad news. Many assume they’re too small to be targeted, but attackers see them as easier prey. The UK Cyber Security Breaches Survey 2025 revealed that over two-thirds of medium-sized businesses experienced an attack in the past year, with ransomware featuring prominently.

The risks include:

Downtime – systems locked and inaccessible for days.
Financial loss – ransom payments, lost revenue, and recovery costs.
Reputation damage – clients lose trust if their data is compromised.
Insurance challenges – some insurers are refusing to pay out without evidence of strong cyber security practices.

At Commercial Networks, our Managed IT Services provide round-the-clock monitoring, patching, and backup management to reduce the risk and impact of ransomware.

How SMBs Can Defend Against RaaS

The good news: SMBs can take practical steps to defend against ransomware-as-a-service. The NCSC’s ransomware guidance recommends:

Backups – maintain secure, offline, and regularly tested backups.
Multi-factor authentication – block unauthorised access to accounts.
Patch management – keep systems and software updated to close vulnerabilities.
Email filtering – reduce the risk of phishing emails reaching staff.
Awareness training – teach employees to spot suspicious attachments or links.

Real-World Example

In 2025, the Harrods data breach showed how third-party vendors can open the door to attackers. Although not strictly a ransomware incident, it demonstrates how attackers exploit weak links in supply chains. Many RaaS groups are now targeting supply chains deliberately, using affiliates to spread ransomware more widely.

Final Thoughts: Ransomware Isn’t Going Away

Ransomware-as-a-service has made it easier than ever for criminals to launch attacks. For SMBs, this means ransomware is not a distant threat, it’s a daily risk. The organisations that thrive will be those that treat security as an ongoing process, not a one-off project.

At Commercial Networks, we help SMBs move from vulnerable to resilient. Through SMB cyber security, Managed IT Services, and ongoing awareness training, we make ransomware defence achievable.
