47% of Organisations Fail to Detect Breach Until Data is Stolen

Ransomware continues to evolve beyond simple file encryption into highly organised operations focused on stealing sensitive information, maintaining prolonged access and exploiting weaknesses before organisations even realise they have been compromised. Today’s attackers are increasingly patient, choosing to remain hidden inside enterprise environments while gathering intelligence, escalating privileges and identifying valuable assets.

A recent report highlighted by Singapore Business Review’s ransomware findings illustrates how serious this problem has become. According to the report, attackers remained inside enterprise networks in Singapore for nearly two and a half weeks on average before being detected during ransomware incidents. Even more concerning, almost half of ransomware victims only discovered the breach after corporate data had already been stolen.

Ransomware is becoming increasingly difficult to detect

Traditional ransomware often announces its presence immediately by encrypting systems and displaying ransom notes. Modern ransomware campaigns operate very differently. Threat actors spend considerable time conducting reconnaissance, identifying high-value systems and disabling security controls before launching the final stage of the attack.

The report found that 47 per cent of ransomware victims only detected the compromise after data had already been exfiltrated, a significant increase compared to the previous year. Another 16 per cent only became aware of the attack after receiving a ransom demand. These figures suggest that many organisations are losing visibility into what is happening within their own environments.

The longer attackers remain undetected, the greater the potential damage. Extended dwell times allow cybercriminals to access additional systems, collect sensitive information and establish persistence mechanisms that make complete eradication more difficult.

Human and operational challenges continue to weaken defences

Technology alone is not responsible for delayed detection. Operational challenges remain a significant factor. The report identifies alert fatigue as one of the primary reasons critical security warnings are delayed or ignored.

Security teams often receive thousands of alerts every day. Distinguishing genuine threats from routine activity becomes increasingly difficult, particularly as attackers deliberately mimic legitimate user behaviour. According to the report, many respondents indicated that threat actors successfully blended into normal business operations or abused valid privileged accounts to avoid raising suspicion.

Encrypted communication channels present another growing challenge. Nearly half of the respondents reported attackers using encrypted traffic to bypass conventional monitoring tools. As encryption becomes the norm across modern enterprise networks, defenders must increasingly rely on behavioural analytics rather than simple signature-based detection.

AI is changing both sides of the cybersecurity battlefield

Artificial intelligence is reshaping cybersecurity at an unprecedented pace. While organisations increasingly deploy AI to automate security operations and improve detection capabilities, attackers are leveraging the same technologies to increase the sophistication and scale of their campaigns.

The report found that almost one-third of organisations identified AI agents, agentic infrastructure and generative AI applications as among their most significant cybersecurity risks. Meanwhile, a separate survey found that businesses in Singapore experienced one of the highest rates of AI-related cyber incidents among the countries surveyed.

AI introduces new forms of risk beyond traditional cyberattacks. Poorly governed AI systems may inadvertently expose sensitive information, create new attack surfaces or introduce vulnerabilities through third-party integrations. As organisations continue adopting AI-powered business tools, security governance must evolve alongside technological innovation.

Advanced threat groups are raising the stakes

The report identified several highly sophisticated threat actors operating within enterprise environments. Among the most prominent were Lazarus Group, the North Korea-linked state-sponsored threat actor, alongside RansomHub and several advanced persistent threat groups.

Unlike opportunistic cybercriminals, these groups often possess significant technical resources and well-developed attack methodologies. They invest substantial effort into remaining undetected while collecting intelligence and establishing long-term access.

Singapore has previously been identified as one of Southeast Asia’s most heavily targeted countries for exploit attacks and Remote Desktop Protocol attacks. This broader threat landscape reinforces that organisations cannot assume they are too small or insignificant to become targets. Modern cybercriminals increasingly automate reconnaissance, allowing them to identify vulnerable organisations at scale.

Faster detection is becoming the most important defence

Preventing every cyberattack is unrealistic. Even organisations with mature security programmes may experience attempted compromises. The critical differentiator is increasingly detection speed.

Continuous monitoring, network visibility, threat hunting and behavioural analytics significantly improve an organisation’s ability to identify malicious activity before attackers achieve their objectives. Rather than relying solely on perimeter defences, organisations should focus on detecting unusual behaviour throughout the network.

Equally important is incident response preparedness. Organisations that regularly rehearse cyber incidents through tabletop exercises and technical simulations are generally better equipped to contain attacks before they escalate into major business disruptions.

Cybersecurity resilience is therefore measured not only by preventing attacks but also by minimising the time between compromise, detection and response.

How Privacy Ninja helps organisations strengthen ransomware resilience

The latest ransomware findings reinforce the importance of combining proactive security testing with continuous monitoring and robust governance. Privacy Ninja helps organisations reduce ransomware risk through a comprehensive portfolio of cybersecurity and data protection services.

Our Vulnerability Assessment and Penetration Testing (VAPT) services identify weaknesses across networks, cloud environments, web applications, APIs and mobile applications before attackers can exploit them. We simulate real-world attack techniques to help organisations understand their true exposure and prioritise remediation based on business risk.

Privacy Ninja also supports organisations through Data Breach Management, helping clients prepare for, respond to and recover from cybersecurity incidents efficiently. Our DPO-as-a-Service further strengthens organisational governance by supporting compliance with the PDPA while improving data protection practices across people, processes and technology. Together, these services enable organisations to build stronger resilience against ransomware, advanced persistent threats and emerging AI-driven cyber risks.

The latest ransomware findings reveal a concerning shift in today’s cyber threat landscape. Attackers are becoming increasingly stealthy, remaining hidden for extended periods while stealing valuable information before launching their final attacks.

Delayed detection, alert fatigue, encrypted communications and AI-enabled attack techniques all contribute to a more complex defensive environment. Organisations must therefore move beyond traditional security models and adopt continuous visibility, proactive testing and well-practised incident response capabilities.

As cybercriminals continue refining their methods, organisations that invest in strong cybersecurity governance, continuous monitoring and regular security assessments will be significantly better positioned to detect threats earlier, minimise operational disruption and protect the sensitive information entrusted to them.
