Patching Vulnerabilities Faster: The Key to Reducing Cyber Risk

A research study released by Trend Micro on March 25, 2025, has revealed a significant correlation between vulnerability patching speed and reduced cybersecurity risks. The study shows that organizations implementing rapid patching protocols experienced a measurable decrease in their Cyber Risk Index (CRI), demonstrating the critical importance of timely security updates in today’s threat environment.

The findings are striking: companies that reduced their patch implementation window from 30 days to 7 days saw an average 34% reduction in successful breach attempts. This highlights the exponential relationship between patching velocity and security posture enhancement.

 The Severity of Delayed Patching

The research examined exploitation patterns across major industries and revealed that threat actors routinely weaponize new vulnerabilities within hours of disclosure. This accelerated attack timeline has fundamentally altered the security equation, creating a narrow defensive window that modern security teams must operate within.

Perhaps most concerning is the discovery that 78% of successful breaches in the past quarter exploited vulnerabilities where patches were available but not yet implemented. This represents a preventable security failure that continues to plague organizations of all sizes.

According to Trend Micro’s 2025 Cyber Risk Report, the overall average Cyber Risk Index improved consistently throughout 2024, with a 6.2-point difference from February to December. However, the overall average CRI of 36.3 still falls within the medium risk level (31-69), indicating that organizations still have several risk factors that need addressing.

 Understanding How CREM Calculates the Cyber Risk Index (CRI)

The Cyber Risk Exposure Management (CREM) solution provides organizations with a quantifiable measure of their security posture through the Cyber Risk Index (CRI). This metric transforms qualitative risk assessments into a numerical value that enables businesses to track progress, compare against industry benchmarks, and prioritize remediation efforts.

 The CRI Scale and Risk Levels

The CRI uses a scale from 0-100 to represent an organization’s security posture:

• Low Risk (0-30): Organizations in this range are considered relatively secure, with immediate significant measures generally not necessary
• Medium Risk (31-69): Organizations have several risk factors that need to be addressed, and it is advisable to consider and implement appropriate countermeasures
• High Risk (70-100): Organizations are exposed to severe risks, and prompt and robust security measures are essential to mitigate potential threats

Research has found that organizations with a CRI above the average have a greater likelihood of suffering from attacks than those with a lower CRI.

 How Vulnerabilities Are Exploited

Trend Micro researchers identified a particularly aggressive exploitation campaign targeting a recently disclosed memory corruption vulnerability in widely-used API management systems. Their analysis revealed sophisticated attackers utilizing a multi-stage attack sequence that begins with vulnerability scanning and progresses to payload delivery within minutes of identifying vulnerable systems.

The report emphasizes that “the speed at which threat actors weaponize new vulnerabilities has reached unprecedented levels,” making the traditional quarterly patching cycle dangerously obsolete.

The research details a representative attack sequence exploiting CVE-2025-11482, a critical vulnerability affecting enterprise API gateways. Initial exploitation typically begins with a memory corruption trigger that enables arbitrary code execution. The complete attack chain from initial exploitation to lateral movement shows the points where prompt patching would terminate the attack sequence.

 Who’s Behind These Exploits

Trend Micro’s Zero-Day Initiative monitoring shows an increase in the use of zero-day exploits by ransomware groups. Prior to 2020, the use of zero-day exploits by ransomware groups was extremely rare, but there have been 59 zero-day exploits leveraged by ransomware attacks since then. It’s possible that ransomware attacks have become profitable enough that groups can now pay for zero-days instead of relying on N-day exploits.

Monitoring of the cybercriminal underground reveals that LockBit, Qilin, and Black Basta were among the top ransomware intrusion sets based on breaches reported on leak sites. Ransomware groups had the most victim enterprises from North America, with 369 successful breaches on companies that did not pay ransom in that region.

 Who Is At Risk

The education sector had the highest average CRI at the beginning of the year and remained among the sectors with the highest CRI by the last quarter of 2024. Enterprises and organizations in this sector are vulnerable to cyberattacks that could disrupt educational services, cause data breaches, lead to intellectual property theft, and damage reputation.

Enterprises in the agriculture and construction industries also have significant work to do. Attack surfaces of enterprises in these sectors are more vulnerable to attacks than other industries, which could mean operational disruption. Both sectors have a strategic position in global supply chains, so the impact of successful attacks might have a ripple effect on an international scale.

Other sectors involved in the supply chain, such as the energy and transportation sectors, should also shift to a more proactive risk management approach to reduce their overall exposure and make their organizations resilient to attacks.

Larger enterprises typically have more complex networks; with more employees comes a larger attack surface, and so their respective security operations centers face a more challenging task of patching vulnerabilities, maintaining proper security configurations, and securing endpoints.

 Effective Remediation Strategies

Organizations scoring in the lowest quartile of the Cyber Risk Index shared common characteristics: extended patching timelines, inconsistent vulnerability scanning, and fragmented security ownership. Conversely, entities achieving favorable CRI scores implemented automated patch management, maintained comprehensive asset inventories, and prioritized vulnerabilities based on exploitation potential rather than solely on CVSS scores.

When properly implemented, automated patch management can detect, test, and deploy critical security updates within hours of release, dramatically reducing the exposure window and consequently lowering an organization’s Cyber Risk Index.

Trend Micro recommends the following key actions to improve cyber risk posture:

1. Optimize security settings to maximize product features and be alerted on misconfigurations, vulnerabilities, and other risks. Leverage native sensors or utilize third-party sources to build a comprehensive view of your attack surface.
2. When a risky event is detected, contact the device and/or account owner to verify the event, and investigate the event using appropriate workbench tools.
3. Inventory stale accounts to delete inactive and unused ones. Disable risky accounts, or reset their passwords with strong ones, and enable multi-factor authentication (MFA).
4. Apply the latest patches or upgrade the version of applications regularly.
5. Apply the latest patches or upgrade the operating system version regularly.

Adopting a risk-based approach allows organizations to anticipate threats, strategize resource allocation, tailor security measures, and enhance situational awareness with the continuous discovery, assessment and mitigation of an enterprise’s IT ecosystem. By identifying high, medium, and low risk components of the attack surface, organizations can create an action plan to prevent attacks before they even happen and lower their overall risk in the near, medium, and long term.
