A significant majority of cyber vulnerabilities exploited by attackers continue to remain unaddressed for extended periods, exposing organizations to prolonged digital risk, according to findings from a recent cybersecurity study. The research indicates that nearly 88 per cent of exploited vulnerabilities remain unresolved for six months or longer, underscoring persistent weaknesses in patch management and cyber hygiene practices across industries.
The study highlights that attackers are increasingly focusing on known and previously disclosed vulnerabilities rather than relying solely on new or zero-day exploits. This trend suggests that delayed remediation, rather than lack of awareness, is a major contributor to successful cyber intrusions. Even after vulnerabilities are actively exploited in real-world attacks, many organizations fail to apply patches or mitigation measures in a timely manner.
Several factors contribute to these delays. Complex IT environments, concerns about system disruption, limited cybersecurity resources and dependence on legacy infrastructure often slow down remediation efforts. In some cases, vulnerabilities persist because affected systems are embedded in critical operations, making immediate patching operationally challenging.
From a risk management perspective, the findings point to a widening gap between vulnerability disclosure and effective remediation. Prolonged exposure increases the likelihood of data breaches, ransomware attacks and operational disruptions, particularly in sectors handling sensitive financial or personal data. The study suggests that attackers benefit from this window of inaction, repeatedly exploiting the same weaknesses across multiple targets.
The research reinforces the importance of prioritized patch management, continuous vulnerability monitoring and stronger coordination between security, IT and business teams. As cyber threats grow in scale and sophistication, regulators and insurers are also paying closer attention to how organizations manage known vulnerabilities and respond to exploitation alerts.
The findings serve as a reminder that timely remediation remains one of the most effective defenses against cyber risk, and that failure to address known issues can significantly amplify financial, operational and reputational exposure.
