Why SMEs Are the New Target for Ransomware Gangs

The threat of ransomware has evolved rapidly over the past few years. What was once a problem reserved for large enterprises and public sector bodies has now shifted dramatically towards a different set of targets, small and medium-sized enterprises. The logic is simple: SMEs are often less equipped, less prepared, and more likely to pay to restore critical operations. That’s made them ideal targets for cybercriminals looking to maximise reward with minimal resistance.

Across the UK, the National Cyber Security Centre has consistently flagged this growing risk. Organisations that once thought they were too small to be noticed are now finding themselves squarely in the sights of international ransomware gangs. Whether you’re an engineering firm with 40 employees or a law office with three branches, the threat is real.

This article explores the driving forces behind this shift and what businesses can do to protect themselves, especially in light of compliance frameworks such as IASME, Cyber Assurance, Cyber Essentials, UK Cyber Security, GDPR, and ISO 27001.

Ransomware-as-a-Service Has Changed the Game

Traditional ransomware attacks were once carried out by technically skilled groups that developed and launched their own campaigns. Today, the ecosystem is far more commercialised. With the rise of Ransomware-as-a-Service (RaaS), anyone with criminal intent can rent the tools they need to launch sophisticated attacks.

This lowers the barrier to entry and vastly increases the number of threat actors. RaaS kits include not only the malware itself but also customer support, tutorials, and even affiliate models that encourage non-technical people to get involved.

SMEs are often viewed as soft targets in this new model. With fewer security controls and leaner IT teams, they’re seen as more likely to pay quickly and without fuss.

The Economics of Targeting SMEs

Cybercriminals are, at their core, economically motivated. While the payoff from attacking a large multinational can be massive, these organisations are more likely to have robust defences, incident response teams, and backups that reduce the impact of ransomware.

SMEs, on the other hand, often lack these layers of protection. They also may not have the cash flow or infrastructure to survive extended downtime. As a result, they are statistically more likely to pay.

A 2024 report from Hiscox found that 53% of UK SMEs had experienced a cyberattack in the last 12 months, and over 30% of those involved ransomware. Alarmingly, only 36% had a fully documented incident response plan in place.

Entry Points That Make SMEs Vulnerable

One of the key reasons SMEs are increasingly targeted is the number of weak entry points in their environments. These include:

• Poorly secured remote desktop access (RDP)
• Unpatched software
• Use of outdated operating systems
• Lack of multi-factor authentication (MFA)
• Low employee awareness of phishing

Many SMEs rely on third-party service providers or outsourced IT support. While this can be cost-effective, it can also introduce risks if those vendors don’t follow strong security protocols.

Phishing Remains a Primary Attack Vector

The most common method of delivering ransomware is still phishing. Emails that appear to come from trusted sources, clients, suppliers, or internal staff, are used to trick users into clicking malicious links or downloading infected attachments.

This is especially dangerous in smaller companies where formal training may be limited. The phishing emails themselves have become harder to spot, often using real names, spoofed domains, and even previous message threads to increase believability.

Organisations aligned with Cyber Essentials are better positioned to defend against phishing. This government-backed scheme mandates controls like email filtering, MFA, and staff training, all critical for reducing phishing success rates.

Supply Chain Weaknesses Amplify Risk

An SME may think they’re too small to matter, but their connection to larger firms can change that. Attackers frequently target smaller suppliers as a stepping stone to reach larger companies.

A breach at a small IT provider, for example, could give an attacker access to multiple clients’ systems. The 2020 SolarWinds attack and the Kaseya breach in 2021 are high-profile examples that showed how widespread the damage can be.

By aligning with frameworks like ISO 27001 and IASME Cyber Assurance, SMEs can demonstrate that they’re not the weakest link in a larger supply chain.

The Role of Cyber Insurance and Compliance Frameworks

There’s been a marked increase in the number of SMEs purchasing cyber insurance. However, insurers are getting stricter. Many now require companies to meet the standards laid out in Cyber Essentials or IASME Cyber Assurance to qualify for coverage.

That’s pushing more organisations to formalise their security policies, implement MFA, encrypt data, and ensure regular backups are in place.

Meanwhile, GDPR continues to loom large. While ransomware primarily targets business continuity, it often results in data breaches that must be reported under GDPR rules. Fines for non-compliance can be devastating, even for small firms.

Detection and Response Gaps Are Widening

The smaller the business, the more likely it is that cybersecurity is treated as a part-time concern. Many SMEs have no dedicated security staff. Often, the office manager or general IT support person is responsible for everything.

This results in significant delays in detecting and responding to incidents. Attackers know this and often plant malware that remains dormant until the most disruptive moment.

By the time an alert is raised, it may be too late. This is why aligning with UK Cyber Security guidance is so important. Regular audits, active monitoring, and tested response plans make a significant difference.

Backups Alone Are No Longer Enough

Many SMEs believe that having a backup is their best defence. While this was once true, modern ransomware groups now steal data before encrypting it. They then threaten to release sensitive information if payment isn’t made, this is known as double extortion.

Even if the data is restored from backup, the reputational damage and regulatory risk remain. This is where frameworks like ISO 27001 prove their value by mandating a holistic approach to information security.

Building Resilience Through Staff Awareness

People remain both the greatest vulnerability and the strongest defence. A well-trained employee can spot a phishing email or flag a suspicious file before it causes damage.

Security awareness training is essential, not optional. It should cover:

• Recognising phishing emails
• Safe use of removable media
• Reporting suspicious behaviour
• Social engineering tactics

Certification under Cyber Essentials requires basic awareness training, but ongoing reinforcement is key to building a security-minded culture.

The Rise of Managed Security Services

As threats grow more complex, more SMEs are turning to managed security service providers (MSSPs). These vendors offer 24/7 monitoring, incident response, and threat intelligence, capabilities that are often out of reach for smaller teams.

However, it’s critical to vet MSSPs carefully. They should be aligned with IASME, Cyber Assurance, and broader UK Cyber Security objectives. Trusting your security to a third party demands the same scrutiny you’d apply to hiring a new executive.

Policy, Process and Culture

Security isn’t just a tool, it’s a mindset. SMEs must embed cybersecurity into their culture, from boardroom discussions to front-desk routines.

That means:

• Documenting policies
• Assigning clear roles
• Conducting regular risk assessments
• Testing incident response plans
• Ensuring suppliers are security-aligned

Frameworks like ISO 27001 and IASME Cyber Assurance provide the scaffolding needed to build this culture sustainably.

Final Thoughts

SMEs can no longer afford to assume they’re beneath the notice of ransomware gangs. The data is clear, and the attacks are real. But with the right strategy, based on education, investment, and frameworks like Cyber Essentials, GDPR, and UK Cyber Security guidance, organisations can turn their vulnerabilities into strengths.

Cybersecurity isn’t a checkbox. It’s a daily discipline. And for SMEs, it may now be the most important investment they make.
