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 analyzes the behavior of the filesystem in two stages - first by creating a filesystem metadata based on file operations during a time interval and comparing it to a normal pattern, and second by analyzing 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 outlined in the patent involves determining patterns of changes in the filesystem based on backup data, calculating abnormal scores to detect abnormal behavior, and presenting indications of infection within a user interface. The system uses machine learning models to assess abnormal behavior and encryption likelihood in files, with features trained on various types of filesystem data. Additionally, the patent covers the recording of filesystem changes in metadata, the use of entropy features to detect encryption, and the assessment of entropies to determine infection. Overall, the patent details a comprehensive approach to ransomware detection in filesystems using backup data and machine learning models.
