Dynamic Network Signature Mapping (DNSM) is introduced as a novel and advanced approach for detecting ransomware threats through adaptive, real-time analysis of network traffic patterns. Utilizing an integrated framework of convolutional and recurrent neural networks, DNSM captures spatial and temporal dependencies within network data, enabling precise classification of ransomware activities even under encrypted or high-volume conditions. Unlike traditional, signature-based methods, DNSM constructs a dynamic and evolving threat profile that reduces the need for manual updates, thereby improving adaptability to emerging ransomware techniques. Empirical results from the study validate DNSM’s ability to maintain high detection accuracy and low false positive rates across a spectrum of network environments, while demonstrating efficient real-time performance critical for high-stakes operational contexts. The modularity of DNSM, coupled with its automated threat scoring and pattern recognition capabilities, establishes it as a resilient solution that addresses the demands of modern ransomware detection, offering a scalable, resource-effective alternative for proactive network security.
