    ADVANCING RANSOMWARE DETECTION SYSTEM USING MACHINE LEARNING
    (Sri Lanka Institute of Information Technology, 2025-09) De Silva, G.A.A.I.S
    Ransomware attacks pose a significant and evolving threat to data security and operational integrity, necessitating advanced detection mechanisms. This project aims to develop an effective ransomware detection system leveraging machine learning techniques, specifically Recurrent Neural Networks (RNN) and auto encoders, to analyze network traffic for anomalies indicative of ransomware activity. Utilizing the UNSW-NB15 datasets, we undertook extensive data preprocessing, including handling missing values and normalizing features, to prepare the datasets for training. The model employs Long Short-Term Memory (LSTM) layers to capture temporal dependencies and patterns within the network traffic data. The training and validation processes focused on normal traffic data to establish a baseline for detecting deviations caused by ransomware. Our results demonstrate high accuracy in distinguishing between normal and ransomware-infected traffic, with a clear ability to identify potential threats in real-time. This innovative approach showcases the potential of RNN-based auto encoders in enhancing cyber security measures. The conclusion emphasizes the system’s effectiveness in providing early warnings of ransomware attacks, thereby significantly aiding in the protection of valuable data assets and maintaining operational continuity.
