Application: Ransomware infection detection in filesystems (Patent ID: US20230409713A1)
The patent filed by Rubrik Inc. describes a system for detecting ransomware infection in filesystems using backup data of machines. The system operates in two stages, first analyzing the behavior of the filesystem by comparing patterns of file operations to a normal pattern, and then examining the content of files for signs of encryption. By combining the results of both stages, the system determines whether the filesystem is infected by ransomware. The method involves using a ransomware detection model to calculate abnormal scores based on changes in the filesystem, detecting abnormal behavior, and presenting an indication of infection within a user interface.
Additionally, the patent includes claims related to training the model feature using training data, recording patterns of changes in filesystem metadata, assessing file encryption based on entropy features, and determining infection based on abnormal behavior and encryption scores. The patent also covers the use of machine learning models to calculate abnormal scores, the representation of normal patterns of changes in the filesystem, and the application of the method to virtual machines. Overall, the patent outlines a comprehensive approach to ransomware detection in filesystems using backup data and behavioral analysis, with a focus on combining multiple indicators to accurately identify infections.
