The increasing prevalence and sophistication of cyber threats have introduced unique challenges in protecting critical systems and sensitive data from evolving ransomware attacks that adapt rapidly to evade conventional detection strategies. Addressing the need for more adaptive and resilient defenses, the Dynamic Threat Signal Clustering (DTSC) model offers an innovative methodology for detecting ransomware through the clustering of threat signals based on distinctive ransomware behaviors. By employing a real-time, high-dimensional clustering algorithm, DTSC can dynamically identify ransomware patterns amidst vast network traffic, demonstrating improved detection accuracy while significantly reducing false positive rates compared to traditional signature-based approaches. DTSC not only enhances operational efficiency through its refined clustering mechanism, which isolates malicious signals even within complex network environments, but also optimizes resource utilization, making it adaptable to both high-traffic enterprise systems and more resource-limited infrastructures. Experimental results indicate that DTSC's ability to continuously recalibrate in response to emerging threats enables robust adaptability, positioning it as a vital addition to the modern cybersecurity landscape. The implications of DTSC's success extend across cybersecurity practices, offering a scalable and highly effective tool for ransomware detection that is capable of safeguarding critical infrastructures against one of the most persistent and rapidly evolving cyber threats.
