The granted patent US12026257B2 outlines a computer-implemented method and system for conducting behavior-based analysis of program execution within an operating system. The method involves monitoring operations performed by a program in a live environment through kernel filter drivers and callback functions. This monitoring encompasses both user space and kernel space operations, generating event data for each monitored operation. The event data is then normalized into a logical structure, allowing for the construction of a stateful model that reflects the hierarchical relationships and attributes of the monitored operations. The system analyzes this model to identify behaviors associated with the program execution and applies a scoring mechanism to assess the likelihood of malware presence based on these behaviors.

Additionally, the patent describes features for real-time updates to the stateful model in response to new events, outputting representations of identified behaviors, and storing these behaviors in a behavioral profile database. The system can be implemented in a cloud-based environment or distributed across multiple computers, facilitating concurrent operation of various programs. The analysis of behaviors may also include aggregating data and determining behavior patterns, ultimately enabling the identification of potential malware within the program execution. This comprehensive approach aims to enhance the security and reliability of software applications by providing detailed insights into their operational behaviors.
