The blog post discusses the visualization techniques used by CrowdStrike to improve the interpretability of deep learning models, particularly convolutional neural networks (CNNs), in detecting malware through PowerShell scripts. It highlights the application of Grad-CAM, a method originating from computer vision, to generate heatmap visualizations that identify and explain the most predictive features for classifying malware. The article details how this technique aids in validating the decision-making criteria of models, ensuring they focus on relevant indicators of malicious activity. It also emphasizes the importance of visualization in confirming that CNNs activate around the appropriate features and describes the process of using Grad-CAM to enhance malware detection capabilities by identifying significant substrings in scripts. Additionally, the post underscores the broader application of these techniques beyond computer vision into natural language processing tasks, showcasing the versatility and potential of CNNs in cybersecurity.
