Ransomware as a Service (RaaS) has turned sophisticated cyberattacks into a criminal subscription business. Attackers no longer need deep technical skills — they rent ready-made tools, execute attacks, and split the proceeds with developers. Singapore businesses, large and small, are firmly in the crosshairs.
The short answer to what you should do: strengthen access controls, maintain tested offline backups, train your staff, and have a written incident response plan. The rest of this article explains why the threat is escalating and what each of those steps actually involves.
What is Ransomware as a Service?
Traditional ransomware attacks required the criminal to build the malicious software themselves. RaaS separates those roles. The ecosystem has three layers:
- Developers — skilled programmers who build, maintain, and update the ransomware code, offering it as a product.
- Operators — groups that manage campaigns, handle ransom negotiations, and run the infrastructure.
- Affiliates — buyers or renters of the toolkit who carry out individual attacks and pay the developers a share of each ransom collected.
This division of labour has made attacks far more scalable. A criminal with almost no technical background can now deploy enterprise-grade ransomware simply by paying a subscription fee. The result is a dramatic increase in attack volume globally, and Singapore has not been spared.
Why Singapore Is a High-Value Target
Singapore’s advanced digital infrastructure, internationally connected businesses, and high concentration of financial and legal data make it a priority target. Two cases illustrate the stakes.
In one widely reported incident, a Singapore-based multinational suffered two weeks of operational disruption after a RaaS-enabled attack encrypted critical data. The attackers demanded SGD 2 million in ransom; total losses exceeded SGD 5 million. In April 2023, law firm Shook Lin & Bok paid approximately SGD 1.89 million (21.07 bitcoins) to the Akira ransomware group.
These are not isolated events. The Cyber Security Agency of Singapore (CSA) has documented a sharp upward trend in reported ransomware incidents. A study by cybersecurity firm Cybereason found that four in five Singaporean organisations surveyed had been targeted by ransomware in the prior 24 months — the highest rate among countries in the survey.
How RaaS Attacks Are Evolving: Double Extortion
The original ransomware model was straightforward: encrypt the victim’s files, demand payment for the decryption key. Businesses with good backups could in principle recover without paying.
Double extortion closes that escape route. Before encrypting, attackers now exfiltrate sensitive data — customer records, legal documents, financial data — and threaten to publish or sell it unless the ransom is paid. Backups protect against the encryption; they do not protect against the leak. This is why pure technical defences are no longer sufficient.
The Three Business Risks to Understand
Operational disruption. A successful ransomware attack can bring critical business functions to a halt. Even if data is eventually recovered, the downtime — days or weeks — carries direct revenue loss, missed deadlines, and broken contracts.
Data theft and extortion. Under double extortion, even a business that can restore from backup faces exposure of confidential client or employee data. The reputational and legal consequences of that exposure are often more damaging than the ransom itself.
Reputational damage. Clients, partners, and regulators notice breaches. For professional services firms, financial institutions, and healthcare providers, a ransomware incident that becomes public can erode trust that took years to build.
Five Practical Defences for Singapore Businesses
1. Harden your access controls
Multi-factor authentication (MFA) on every account is the single most effective measure against the credential-based intrusions that typically precede a ransomware deployment. Disable legacy authentication protocols that do not support MFA. Segment your network so that a compromised endpoint cannot easily reach your most critical systems.
2. Maintain tested offline backups
The word “tested” is critical. A backup that has never been used in a recovery drill is an untested assumption. Follow the 3-2-1 rule: three copies of data, two different media types, one offline and air-gapped. Test restoration quarterly.
3. Build and rehearse an incident response plan
An incident response plan written in a calm moment is invaluable during the chaos of a live attack. It should define: who is the incident lead, who contacts law enforcement and the CSA, who speaks to clients and media, and what the decision criteria are for paying or not paying a ransom. Revisit and rehearse it at least annually.
4. Train your staff
The most common entry point for ransomware is a phishing email clicked by an employee. Security awareness training — covering phishing recognition, safe link handling, and what to do when something looks suspicious — reduces that surface area substantially. Training does not need to be technical; it needs to be regular and practical.
5. Think carefully before paying a ransom
Most cybersecurity professionals and law enforcement agencies advise against paying. Payment does not guarantee recovery, funds criminal operations, and can expose the organisation to regulatory scrutiny. Before reaching that decision in a crisis, have legal counsel and a specialist incident response firm on retainer so you are not making the call cold.
The Cybersecurity Workforce Dimension
Every item on the list above requires people who understand how to implement and maintain it. Singapore’s demand for cybersecurity professionals continues to outpace supply. For individuals looking to enter the field, roles in threat detection, incident response, and security operations are genuinely in demand — and many of the people now working in these roles came from non-technical backgrounds.
At CFCI, 75% of graduates who secured cyber roles had no prior IT background. If you are curious about whether a career in cybersecurity is within reach, the starting point is understanding the landscape — which is exactly what our free information session covers.

Protecting Your Business Starts With the Right Knowledge
Ransomware as a Service is not going away. The economics of the model are too attractive, and the barriers to entry for criminals are too low. For Singapore businesses, the question is not whether to invest in cybersecurity resilience — it is where to start and how to build competence in-house over time.
If you want to strengthen your organisation’s human layer — the staff who recognise threats, respond to incidents, and maintain the defences — or if you are personally exploring a move into cybersecurity, we run a free information session that covers both the threat landscape and how practical skills are built.

Frequently Asked Questions
What is Ransomware as a Service (RaaS)?
Ransomware as a Service is a criminal business model where developers create and lease ransomware tools to affiliates, who then carry out attacks and share a cut of the ransom. It works like a subscription platform, dramatically lowering the technical barrier to launching a ransomware attack.
How common are ransomware attacks on Singapore businesses?
The Cyber Security Agency of Singapore (CSA) reported an 89% increase in ransomware cases in a single year during the early 2020s, and a Cybereason study found four in five Singaporean organisations had been targeted within a 24-month window — the highest rate among the countries surveyed.
Should a company pay a ransomware demand?
Most cybersecurity experts and law enforcement agencies advise against paying. Payment funds further criminal activity, does not guarantee data recovery, and may expose the organisation to legal risk in certain jurisdictions. The better approach is prevention: offline backups, tested recovery procedures, and a documented incident response plan.
What is the best first step a Singapore SME can take against ransomware?
Start with the basics: enforce multi-factor authentication on all accounts, maintain tested offline backups, keep software patched and up to date, and run regular staff awareness training.
