• Abstract summary: In the face of increasing cyber threats, particularly ransomware attacks, there is a pressing need for advanced detection and analysis systems. Most of these proposals leverage non-incremental learning approaches that require the underlying models to be updated from scratch to detect new ransomware. This approach is problematic because it leaves sensitive data vulnerable to attack during retraining, as newly emerging ransomware strains may go undetected until the model is updated. We present the Sysmon Incremental Learning System for Analysis and Detection (SILRAD), which enables continuous updates to the underlying model and effectively closes the training gap.

• Abstract: In the face of increasing cyber threats, particularly ransomware attacks, there is a pressing need for advanced detection and analysis systems that adapt to evolving malware behaviours. Throughout the literature, using machine learning (ML) to obviate ransomware attacks has increased in popularity. Unfortunately, most of these proposals leverage non-incremental learning approaches that require the underlying models to be updated from scratch to detect new ransomware, wasting time and resources. This approach is problematic because it leaves sensitive data vulnerable to attack during retraining, as newly emerging ransomware strains may go undetected until the model is updated. Furthermore, most of these approaches are not designed to detect ransomware in real-time data streams, limiting their effectiveness in complex network environments. To address this challenge, we present the Sysmon Incremental Learning System for Ransomware Analysis and Detection (SILRAD), which enables continuous updates to the underlying model and effectively closes the training gap. By leveraging the capabilities of Sysmon for detailed monitoring of system activities, our approach integrates online incremental learning techniques to enhance the adaptability and efficiency of ransomware detection. The most valuable features for detection were selected using the Pearson Correlation Coefficient (PCC), and concept drift detection was implemented through the ADWIN algorithm, ensuring that the model remains responsive to changes in ransomware behaviour. We compared our results to other popular techniques, such as Hoeffding Trees (HT) and Leveraging Bagging Classifier (LB), observing a detection accuracy of 98.89% and a Matthews Correlation Coefficient (MCC) rate of 94.11%, demonstrating the effectiveness of our technique.

  Deep learning models are vulnerable to Trojan attacks, where an attacker can install a backdoor during training time to make the resultant model misidentify samples contaminated with a small trigger patch. We propose a novel trigger reverse-engineering based approach whose computational complexity does not scale with the number of labels, and is based on a measure that is both interpretable and universal across different network and patch types. In experiments, we observe that our method achieves a perfect score in separating Trojaned models from pure models, which is an improvement over the current state-of-the art method.
