This paper introduces a novel integrated hybrid malware attack detection algorithm, focusing on enhancing cybersecurity within blockchain systems by addressing the prevalent challenges of Byzantine fault tolerance, Reentrancy, and DDOS attacks.The significance of this research lies in its contribution to safeguarding blockchain technology, a cornerstone for secure,decentralized digital transactions, against sophisticated malware threats. Current cybersecurity solutions frequently fall short of offering a complete defense mechanism, making it difficult to effectively combat a variety of dynamic malware attacks atthe same time. Thus, the main objective of this research is to provide a hybrid framework that combines DDOS attack prevention, reentrancy attack detection, and Byzantine fault tolerance detection into a single, cohesive architecture. Theproposed hybrid framework encompasses a detailed algorithmic approach integrating SHA-256 and DSA to analyze theaforementioned three malware attacks. A hybrid model combining these algorithms, implemented in one block, has been developed to mitigate malicious activity. These measures aim to improve computational complexity and expedite execution within the network of nodes. To test the efficacy of the proposed framework, the approach is tested on the NSL-KDD dataset to analyze the malicious activities. The performance analysis of the proposed frameworks presents a recall and F1 score of .73 and .68 respectively. Furthermore, for efficient mitigation, the time and space complexity analysis are performed on proposed algorithms for attack analysis, which resulted in a combination of constant and linear time complexity operations. The findings reveal that the proposed algorithm successfully identifies and mitigates the targeted malware attacks and maintains optimal performance in terms of time and space complexity. This research's contribution to the cybersecurity field is significant, offering a robust, scalable solution that enhances the resilience of blockchain networks against a broad spectrum of malware attacks.

Digital finance emerges and grows along with the environment of the unlimited integration of information technology and finance. This led to a shift from the traditional way of performing finance in different areas to another digital one. With the ongoing evolution of technology, financial innovation has made new inventions. More intelligent digital finance has emerged, which creates new opportunities and facilities. The COVID-19 pandemic has accelerated global digital transformation by altering businesses' and consumers' relationships with digital technologies in months. Digital finance becomes a necessity and offers previously unseen opportunities. The digitalization process also poses new challenges and risks which require a continuous update of regulations set by supreme committees and institutions to safeguard national security. Strict legal law is needed to strengthen trust and confidence in using e-services. Progress in three key areas will boost the prospects for broader adoption of digital finance, crypto, and decentralized finance (DeFi) markets.
